The 2 main components of the CNS
Division of the PNS that controls involuntary body functions
What is the autonomic nervous system?
Where the neuron nucleus is located

What is the cell body?
Missing one or more cones
What is color blindness?
The 2 photoreceptors in the eye
A sudden involuntary response to a stimulus
What is a reflex?
Draw an ear diagram. Label the major structures and explain how sound travels to the brain
Pinna -> Auditory canal -> Tympanic membrane -> Malleus -> Incus -> Stapes (through oval window) -> Cochlea -> Cochlear nerve -> Brain

The largest portion of the brain
What is the cerebrum?
Division of the PNS that controls voluntary muscle actions
What is the somatic nervous system?
Neuron structure that receives the stimulus

What is a dendrite?
A slight brain injury; common in sports
What is a concussion?
Structure that creates the boundary between the outer and middle ear
What is the tympanic membrane (ear drum)?

What is a cataract?
Brain structure responsible for balance and coordination
What is the cerebellum?
Pain in the legs/feet could indicate nerve damage in this location
What is the low back (lumbar) region?
Neuron structure that transmits impulses away from the cell body

What is the axon (or axon tail)?
Brain tissue dies when blood flow is restricted (either by a blood vessel rupture or a blood clot)
What is a stroke (cerebrovascular accident)?
The region of the ear that is necessary for hearing and balance
What is the inner ear?
Lobe responsible for vision and color perception

What is occipital lobe (D)?
What is the brain stem?
What is the sympathetic division?
The gaps between the Schwann cells of the myelin sheath

What are the Nodes of Ranvier?
Constant ringing or clicking in the ear
What is tinnitus?
Sense that uses olfactory receptors?
What is smell?
The 3 protective membranes surrounding the brain and spinal cord (collectively named)
What are the meninges?
The 4 lobes of the brain
What are the frontal, parietal, temporal and occipital lobes?
Name the following pathway: receptor -> sensory neuron -> interneuron -> motor neuron -> effector
What is the reflex arc?
The gap between the axon terminals of one neuron and the dendrites of the next neuron
What is the synapse or synaptic cleft?
Autoimmune disorder that destroys the myelin sheath causing muscle weakness, visual and speech disturbances
What is multiple sclerosis (MS)?
What are the malleus, incus, and stapes (hammer, anvil, and stirrup)?
The 5 taste sensations
What are sweet, salty, bitter, sour, and umami?
