Is the largest part of the nervous system that involves the brain and spinal cord?
the largest part of the nervous system is the peripheral nervous system (PNS) which includes all nerves in all parts of the body except the brain and spinal cord.
What organs make up the nervous system?

Where can one find information on the peripheral nervous system?

What transmits impulses from body organs to cns?

Why is the patellar reflex called a somatic reflex?
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
Does the addition of ether to the nerve cause any permanent alteration in neural response?
no, just temporary
a chemical that transmits a nervous systems signal across a synapse.
What happens to your nervous system after taking magic mushrooms?
The active compounds in magic mushrooms (and their metabolites, as psilocybin is metabolized into psilocin, which is also present in the mushrooms) bind to a specific serotonin receptor in the brain, the 5-HT2A receptor. Activation of this receptor leads to the psychedelic effects through poorly understood mechanisms. Contrary to fairly widespread belief, these compounds have not been shown to be neurotoxic or cause damage to the brain.
Which part of the nervous system is used to coordinate a reflex response?
A spinal reflex is a reflex that is centered in the spinal cord. The parts of the nervous system in one of these include the spinal cord as well as deep tendon nerves and sensory nerves.
What part of the nervous system brings messages to your brain through your spinal cord?
The sensory nervous system. This brings information into the cord and to the brain.
somatic nervous system
Grey matter is nerve tissue that primarily consists of nerve cell bodies, dendrites, and unmyelinated axons, thus having a gray appearance.
What are the symptoms of L5 nerve root effacement?
