Additionally, the nervous tissue that reach out from the brain and spinal cord to the rest of the body nerves are also part of the nervous system. We can anatomically divide the nervous system into two major regions: the central nervous system CNS is the brain and spinal cord, the peripheral nervous system PNS is the nerves Figure The brain is contained within the cranial cavity of the skull, and the spinal cord is contained within the vertebral canal of the vertebral column. The peripheral nervous system is so named because it is in the periphery—meaning beyond the brain and spinal cord.

Figure Functional Divisions of the Nervous System In addition to the anatomical divisions listed above, the nervous system can also be divided on the basis of its functions. The nervous system is involved in receiving information about the environment around us sensory functions, sensation and generating responses to that information motor functions, responses and coordinating the two integration. Sensation refers to receiving information about the environment, either what is happening outside ie: heat from the sun or inside the body ie: heat from muscle activity. When information arises from sensory receptors in the skin, skeletal muscles, or joints this is known as somatic sensory information; when information arises from sensory receptors in the blood vessels or internal organs, this is known as visceral sensory information. The nervous system produces a response in effector organs such as muscles or glands due to the sensory stimuli.

16.4 The Peripheral Nervous System
Posted on 9-May-2021
When the effector organ is a skeletal muscle, the information is called somatic motor; when the effector organ is cardiac or smooth muscle or glandular tissue, the information is called visceral autonomic motor. Voluntary responses are governed by the somatic nervous system and involuntary responses are governed by the autonomic nervous system, which are discussed in the next section. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed. This is called integration see Figure In the CNS, stimuli are compared with, or integrated with, other stimuli, memories of previous stimuli, or the state of a person at a particular time.

This leads to the specific response that will be generated. The CNS then creates a motor plan that is executed by the efferent branch working with effector organs. Chapter Review The nervous system can be separated into divisions on the basis of anatomy and physiology. The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function. Functionally, the nervous system can be divided into those regions that are responsible for sensation, those that are responsible for integration, and those that are responsible for generating responses.

Scientists who research this topic typically use twin studies to determine the heritability of intelligence. The findings from this study reveal a genetic component to intelligence figure below. If parents were to provide their children with intellectual stimuli from before they are born, it is likely that they would absorb the benefits of that stimulation, and it would be reflected in intelligence levels. Figure 7. The correlations of IQs of unrelated versus related persons reared apart or together suggest a genetic component to intelligence. The reality is that aspects of each idea are probably correct. Certainly, there are behaviors that support the development of intelligence, but the genetic component of high intelligence should not be ignored. As with all heritable traits, however, it is not always possible to isolate how and when high intelligence is passed on to the next generation. Range of Reaction is the theory that each person responds to the environment in a unique way based on his or her genetic makeup.

According to this idea, your genetic potential is a fixed quantity, but whether you reach your full intellectual potential is dependent upon the environmental stimulation you experience, especially in childhood. Think about this scenario: A couple adopts a child who has average genetic intellectual potential. They raise her in an extremely stimulating environment. It is likely that the stimulating environment will improve her intellectual outcomes over the course of her life. But what happens if this experiment is reversed? If a child with an extremely strong genetic background is placed in an environment that does not stimulate him: What happens? Another challenge to determining origins of high intelligence is the confounding nature of our human social structures. The same is true for socioeconomic status. Children who live in poverty experience more pervasive, daily stress than children who do not worry about the basic needs of safety, shelter, and food. These worries can negatively affect how the brain functions and develops, causing a dip in IQ scores.

Jensen had administered IQ tests to diverse groups of students, and his results led him to the conclusion that IQ is determined by genetics. In his theory, Level I is responsible for rote memorization, whereas Level II is responsible for conceptual and analytical abilities. According to his findings, Level I remained consistent among the human race. In fact, Rushton and Jensen reviewed three decades worth of research on the relationship between race and cognitive ability.

Learning disabilities are considered specific neurological impairments rather than global intellectual or developmental disabilities. A person with a language disability has difficulty understanding or using spoken language, whereas someone with a reading disability, such as dyslexia, has difficulty processing what he or she is reading. Often, learning disabilities are not recognized until a child reaches school age.

The intelligence levels of all individuals seem to benefit from rich stimulation in their early environments. Highly intelligent individuals, however, may have a built-in resiliency that allows them to overcome difficult obstacles in their upbringing. Learning disabilities can cause major challenges for children who are learning to read and write.

The brain controls what we think and feel, how we learn and remember, and the way we move and talk. But it also controls things we're less aware of — like the beating of our hearts and the digestion of our food. Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain.

The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant. What Are the Parts of the Nervous System? The nervous system is made up of the central nervous system and the peripheral nervous system: The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system. The human brain is incredibly compact, weighing just 3 pounds. It has many folds and grooves, though. These give it the added surface area needed for storing the body's important information. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body. Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae.

They're both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products. What Are the Parts of the Brain? The brain is made up of three main sections: the forebrain, the midbrain, and the hindbrain. The Forebrain The forebrain is the largest and most complex part of the brain. It consists of the cerebrum — the area with all the folds and grooves typically seen in pictures of the brain — as well as some other structures under it. The cerebrum contains the information that essentially makes us who we are: our intelligence, memory, personality, emotion, speech, and ability to feel and move. Specific areas of the cerebrum are in charge of processing these different types of information.

These are called lobes, and there are four of them: the frontal, parietal, temporal, and occipital lobes. The cerebrum has right and left halves, called hemispheres. They're connected in the middle by a band of nerve fibers the corpus callosum that lets them communicate. These halves may look like mirror images of each other, but many scientists believe they have different functions: The left side is considered the logical, analytical, objective side. The right side is thought to be more intuitive, creative, and subjective. So when you're balancing your checkbook, you're using the left side. When you're listening to music, you're using the right side. It's believed that some people are more "right-brained" or "left-brained" while others are more "whole-brained," meaning they use both halves of their brain to the same degree.

The outer layer of the cerebrum is called the cortex also known as "gray matter". Information collected by the five senses comes into the brain to the cortex. This information is then directed to other parts of the nervous system for further processing. For example, when you touch the hot stove, not only does a message go out to move your hand but one also goes to another part of the brain to help you remember not to do that again. In the inner part of the forebrain sits the thalamus, hypothalamus, and : The thalamus carries messages from the sensory organs like the eyes, ears, nose, and fingers to the cortex.

How Does the Nervous System Work? The basic workings of the nervous system depend a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body. All neurons, however, relay information to each other through a complex electrochemical process, making connections that affect the way we think, learn, move, and behave. Intelligence, learning, and memory. As we grow and learn, messages travel from one neuron to another over and over, creating connections, or pathways, in the brain.

It's why driving takes so much concentration when someone first learns it, but later is second nature: The pathway became established. In young children, the brain is highly adaptable. In fact, when one part of a young child's brain is injured, another part often can learn to take over some of the lost function. But as we age, the brain has to work harder to make new neural pathways, making it harder to master new tasks or change set behavior patterns. That's why many scientists believe it's important to keep challenging the brain to learn new things and make new connections — it helps keeps the brain active over the course of a lifetime.

The things we've done, learned, and seen are first processed in the cortex. Then, if we sense that this information is important enough to remember permanently, it's passed inward to other regions of the brain such as the hippocampus and amygdala for long-term storage and retrieval. As these messages travel through the brain, they too create pathways that serve as the basis of memory.

Different parts of the cerebrum move different body parts. The left side of the brain controls the movements of the right side of the body, and the right side of the brain controls the movements of the left side of the body. When you press your car's accelerator with your right foot, for example, it's the left side of your brain that sends the message allowing you to do it. Basic body functions. A part of the peripheral nervous system called the autonomic nervous system controls many of the body processes we almost never need to think about, like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system prepares the body for sudden stress, like if you witness a robbery. When something frightening happens, the sympathetic nervous system makes the heart beat faster so that it sends blood quickly to the different body parts that might need it.

Light entering the eye forms an upside-down image on the retina. The retina transforms the light into nerve signals for the brain. The brain then turns the image right-side up and tells us what we are seeing. Every sound we hear is the result of sound waves entering our ears and making our eardrums vibrate. These vibrations then move along the tiny bones of the middle ear and turned into nerve signals. The cortex processes these signals, telling us what we're hearing. The tongue contains small groups of sensory cells called taste buds that react to chemicals in foods. Taste buds react to sweet, sour, salty, bitter, and savory. The taste buds send messages to the areas in the cortex responsible for processing taste. Olfactory cells in the mucous membranes lining each nostril react to chemicals we breathe in and send messages along specific nerves to the brain. The skin contains millions of sensory receptors that gather information related to touch, pressure, temperature, and pain and send it to the brain for processing and reaction.
