The peripheral nervous system is a network of nerves that transfer messages to the central nervous system (CNS) so that the CNS can interpret the messages.
What is the peripheral nervous system and how does it work with the central nervous system?

Dys is a prefix that means bad;painful.

Neurons ( nerve cells) are the functional units of the nervous system.
What are neurons?

The three functions of the cerebrospinal fluid are: 1) CSF provides shock absorption between the brain & skull and the spinal cord and vertebrae. 2) The brain and spinal cord float in the CSF and this helps reduce their apparent weight. 3) CSF helps to maintain chemical homeostasis.
What are the three functions of the cerebrospinal fluid (CSF)?
300
Nerve.
what does neur/o mean?

The three main parts of a neuron are cell body, dendrites and axon.

The brain is an organ located inside the cranial cavity. The 100 billion neurons in the brain form the main control center of the body. The brain controls consciousness, memory, planning, voluntary actions and also functions as the maintenance of respiration, heart rate, blood pressure and digestion.

The two divisions of the autonomic nervous system are the sympathetic and the parasympathetic. The sympathetic division forms the body's "fight or flight" responses to stress, danger, excitement, exercise, emotions and embarrassment. The parasympathetic division forms the body's "rest and digest" response when the body is relaxed, resting, or feeding.

The spinal cord is a long, thin mass of bundled neurons that carries information through the vertebral cavity. The white matter of the spinal cord serves as the main conduit of nerve signals to the body from the brain. The grey matter of the spinal cord integrates reflexes to stimuli.
What is the spinal cord and what are the functions of the spinal cord?
500
The three functions of The Nervous System are: 1) Sensory-Involves collecting information from sensory receptors that the monitor the body's internal and external conditions. 2) Integration- This involves the processing of sensory signals. 3) Motor-This involves stimulating motor neurons.
What are the three functions of The Nervous System and what do they involve?
500
Meninges and it is the membrane covering the brain and the spinal cord.
What does mening/o, meningi/o stand for and what does it mean?
500
Reflexes. Reflexes allow the body to respond to stimuli quickly by sending responses to effectors before the nerve signals reach the conscious parts of the brain.
What are fast, involuntary responses to stimuli called and what do they do?
500
Esthesia is a suffix that means sensation; feeling.
Is esthesia a suffix or prefix and what does it mean?
