Question

Describe the differences between the functions of the central nervous system and peripheral nervous system (5 Points) List and describe the primary functions of the 4 major lobes of the cerebral cortex

Answer 1

Central nervous system	Peripheral nervous system
The CNS contains the brain and the spinal cord.	The PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body
When the sensory input reaches the CNS, the spinal cord and the brain figure outs what it exactly means, then they quickly orders out the body parts that needs to move faster.	It sends information gathered by the body's sensory receptors to the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body. These nerves which carry information in a way of nerve impulses to and from the brain are called cranial nerves. The nerves that carry impulse to and are carrying information from the spine are called spinal nerves.

The cerebrum is the largest part of the human brain and the cerebral cortex is divided into four sections whihc are called "lobes". The main lobes are: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. There function is listed below:

• The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behavior.
• The occipital lobe functions in processing sensory information regarding the location of parts of the body as well as interpreting visual information and processing language and mathematics.
• The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex.
• The temporal lobe is involved in primary auditory perception, such as hearing, and holds the primaryauditory cortex.
