sensory nerves, carry messages from the organs to the brain and spinal cord
parasympathetic nerves
involuntary or autonomic nerves. regulate heart rate and respiration, balances out sympathetic nerves
sympathetic nerves
autonomic nerves that affect the body during times of stress.
The central nervous system is made up of?
the brain and spinal cord
The peripheral nervous system is made up of?
Cranial nerves (12 pair)
Spinal nerves (31 pair)
Autonomic nerves divided into parasympathetic and sympathetic
Parts of the brain are?
Cerebrum
Thalamus
Hypothalamus
Cerebellum
Pons
Medulla Oblongata
Cerebrum is responsible for?
Thinking, personality, sensations, movements and memory
Thalamus is responsible for?
sensory impulses such as pain
Hypothalamus is responsible for?
body temp, sleep, sex drive, appetite, controls the pituitary glans
Cerebellum is responsible for?

Pons is responsible for?
connection of nerves to the eyes and face
Medulla oblongata is responsible for?
regulating the heart, blood vessels and respiratory system. Crosses over left to right, right to left.
Cauda equina
the tail end of the nerves in the spinal column.
spinal cord
nervous tissue extending from the Medulla oblongata to the second lumbar vertebrae where it ends with the cauda equina
gray matter
found in the brain and spinal cord, contains cell bodies and dendrites of peripheral nerves
white matter
myelin sheath, found in the spinal cord, covers gray matter, contains nerve fibers
meninges
membranes that cover the brain and spinal cord
The three meninges are?
dura mater
arachnoid membrane
pia mater
The cerebral cortex is?
the outer region of the cerebrum, contains sheets of nerve cells, gray matter of the brain
