The nervous system is the body's - ✔✔control center
The central nervous system consists of - ✔✔brain and spinal cord and their associated structures
The peripheral nervous system is comprised of - ✔✔the nerves traveling from the brain or spinal cord to
the target organs and back
The somatic nervous system carries out - ✔✔conscious activities, such as walking, eating, etc
The autonomic nervous system performs functions that - ✔✔don't require conscious thought, such as
breathing, blood pressure, and heart rate
The basic structural and functional unit of the nervous system is the - ✔✔neuron or nerve cell
2 Important types of neurons are - ✔✔sensory neurons and motor neurons
Sensory neurons carry signals of - ✔✔touch, taste, etc to the brain
Motor neurons carry instructions from - ✔✔the brain to the muscles, causing them to move
The primary purpose of a neuron is to - ✔✔transmit an electrical signal that acts either to signal other
neurons or to cause a change in a target organ, such as a muscle or gland
Depolarization is - ✔✔the change in membrane potential that occurs when a nerve is stimulated
, Repolarization is - ✔✔the reestablishment of normal resting membrane potential
Some of the more important neurotransmitters include - ✔✔acetylcholine, norepinephrine, gamma-
aminobutyric acid (GABA), dopamine, enkephalins, serotonin
Reflexes - ✔✔involuntary motor movements initiated by specific sensory input
Receptors - ✔✔nerve endings that detect changes in the environment
Gustatory Sense - ✔✔sense of taste
Olfactory Sense - ✔✔sense of smell
Auditory Sense - ✔✔sense of hearing
The third eyelid found in some species is referred to by which name - ✔✔nictitating membrane
Which receptors are involved with the proprioception sense - ✔✔stretch receptors in the muscles,
tendons, and ligaments
Ipsilateral reflex refers to - ✔✔reflex where the stimulus and response are both on the same side of the
body
What is the test for a proprioception deficit - ✔✔flip over a foot while the animal is standing and see if
the animal corrects the position
What is true of gray matter - ✔✔it makes up the outer tissue layer in the brain
