What are the functions of the peripheral nervous system?

Answer 1

Question 1. What is the nervous system in age related ? Why do these age related changes in brain structure, metabolism, and function occur ? Question 2. How to affects special senses and characterize intrinsic age related changes?

Answer 2

it is outside the brain and spinal cord.
his system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let's take a look at the peripheral nervous system.

Answer 3

When a sharp knife accidentally cuts your finger, neurons in your skin release chemical signals that travel to nerves in the spinal cord and then on to your brain. The brain then interprets the signals as pain.

Answer:

There are many types of nerves present in the body. The optic nerves in the eye transmute light into signals for vision, nerves associate with pain are present in almost every body part. Other nerves are associated with detecting temperature, body positions, hearing, and balance.

Most glands and your heart are tied to detectors by sensors that monitor temperature conditions, CO2 levels in the blood, sugar in the blood, and emotional state to affect the associated organ or gland.

Answer 4

The peripheral nervous system is functionally as well as structurally divided into the somatic nervous system and autonomic nervous system. The somatic nervous system is responsible for coordinating the body movements, and also for receiving external stimuli. It is the system that regulates activities that are under conscious control. The autonomic nervous system is then split into the sympathetic division, parasympathetic division, and enteric division. The sympathetic nervous system responds to impending danger, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement one feels due to the increase of adrenaline in the system. The parasympathetic nervous system, on the other hand, is evident when a person is resting and feels relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and genitourinary systems. The role of the enteric nervous system is to manage every aspect of digestion, from the esophagus to the stomach, small intestine and colon.

Answer 5

I think you mean Central and Peripheral Nervous Systems.\

The CNS controls the brain and spinal chord, and the PNS controls cranial and skeletal nerves.

There are two types of nerves in the PNS: Sensory Nerves and Motor Nerves.

Of Motor Nerves, Somatic Motor Nerves are in charge of controlling skeletal muscles (some people think of this as 'voluntary'), and Autonomic Motor Nerves are in charge of everything else (automatic response, or 'involuntary').

Finally, Autonomic nerves can be further divided into two categories:

Sympathetic nerves, which are in use during 'fight or flight' situations, i.e. 'omg there's a killer clown, i need to send blood and energy away from digestion and sex organs (unless you're attracted to killer clowns :P ), and send it all to my limbs and increase my heart rate so I can fight back'

and Parasympathetic nerves, which are in use during 'rest and relaxation', i.e. 'yay i just ate the killer clown, there' s no more danger but I should probably focus on digesting now instead of having all this blood in my limbs, which i will not be using because i'm gonna spend my afternoon in my Lazyboy playing Skyrim'

I hope that helped.

Answer 6

the peripheral nervous system is used to activate a muscle or group of mussels. they receive a signal or neural response from the brain through the spinal cord. an example is if you kick a ball. It is also known as the voluntary nervous group; however, they don't always need the brain to function. an example is if you step on a sharp object your foot will move off without any concise thought.

Answer 7

sensory nervous system sends informaton to the CNS; Motor nervous system carries information from the CNS.
