CNS
Links the encephalon to the spinal cord
What is the brain stem?
The controls involuntary function of the vital organs
What is the autonomic PNS?
Perceives stimulus such as sight and touch
What is a receptor?
The three protective membranes filled with cerebrospinal fluid that protect the brain
What are the meninges?
Dilates the pupil, increases heart rate, slows digestion, stimulates adrenal glands and glucose release, relaxes the bladder
What is the parasympathetic nervous system?
This transmits signals from the spinal cord to muscles
What is a motor nerve?
The two parts that make up the Central Nervous System.
What are the encephalon and the spinal cord?
The 31 pairs of nerves that stem from the spinal cord and the 12 pairs of nerves that stem from the encephalon
What are the spinal nerves and cranial nerves?
What is an effector organ?
This part of the central nervous system processes reflex actions before the brain becomes aware of them
What is the spinal cord?
The system tha coordinates all the functions of the body
What is the Central Nervous System?
This controls voluntary movements
What is the somatic PNS?
This transmits the impulse to the spinal cord, and then to the cerebral cortex
What is a sensory nerve?
The neuroal pathway that controls autonomic, involuntary response to stimulus
What is the reflex arc?
The brain' soutermost layer of gray matter, has lots of folds and ridges
What is the cerebral cortex?
Contracts the pupil, reduces heart rate, stimulates digestion, contracts the bladder, stimulates the reproductive organs
What is the sympathetic nervous system?
This converts the information received from the sensory nerve into a conscious sensation
What is the cerebral cortex?
This neuron generates an immediate response command
What is an interneuron?
