Are reflexes mediated via the central nervous system or the peripheral nervous system or both?
Kristaxx
Usually when we talk about reflexes -we are referring to two things: primary sensory processing (peripheral nervous system) followed by a motor response (central nervous system). These types of reflexes do not require higher-order cognitive function to occur - but the brain is made aware of what is going on, presumably so that we learn to avoid the harmful stimulus in the future.
For example, the accidental placement of a hand on a hot surface would usually result in an immediate withdrawal reflex. What's happening here is that pain receptors in the skin - in this case 'nociceptors' activated by thermal stimuli - send impulses to neurons in the spinal cord (the spinal cord is part of the central nervous system) that share circuits with neurons that control muscle contractions. These in turn fire, resulting in an immediate flexion (movement toward the body) of the affected limb.

All nervous tissue outside of the central nervous system is part of this nervous system?
The peripheral nervous system is made up of all the nerves outside the central nervous system.

peripheral nervous system
What is the purpose of newborn reflexes?
Testing for reflexes is an important part of the neurological physical examination in order to detect abnormalities in the central or peripheral nervous system.
Are nerves are found in both the central nervous system and the peripheral nervous system?
Yes. You get different types of of nerves and some are associated with the central nervous system and others with the peripheral nervous system

The nervous system is divided into which two subsystems?
The Central Nervous System and Peripheral Nervous system

What nerves are not apart of the central nervous system?
There are only two nervous systems, Central and Peripheral. So Peripheral is your answer

The portion of the nervous system away from the central nervous system?
peripheral nervous system
What are the two distinct branches in the nervous system?
The central nervous system (composed of the brain and spinal cord) and the peripheral nervous system (composed of the rest).

What are the division of nervous?
the central nervous system and the peripheral
What does the nervous system compose of?
peripheral nervous systemthe peripheral nervous systemperipheraThe peripheral nervous system branches from the central nervous systemIt is called the Peripheral Nervous System(PNS).
What are two main jobs of the nervous system?
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
