An injury to the head left Maria with the inability to filter sensory input, what area of her brain was damaged?
pons
cerebellum
medulla oblongata
thalamus
Damage to which part of the brain is most deadly?
midbrain
pons
medulla oblongata

Which part of the brain controls the endocrine system?

Why do we have two enlargements (cervical and lumbar) in our spinal cord?
The cervical enlargement supplies nerves to upper limbs while the lumbar supplies nerves to lower limbs
Our spinal cord has to support more weight in these areas so it needs to be thicker
The cervical enlargement is responsible for all sensory information while the lumbar for all motor information
Both enlargements serve no physiological purpose that we know of
If a person had a major injury between C3 and C4 (cervical) area in their spinal cord, they would suffer from
Alzheimer’s
paraplegia
quadriplegia
CTE
If a person had a major injury between T1 and T10 (thoracic) area in their spinal cord, they would suffer from
Alzheimer’s
paraplegia
quadriplegia
CTE
________ roots take _________________ commands to the muscles and glands.
dorsal; sensory
dorsal; motor
ventral; sensory
ventral; motor
If a person suffered damage to one of the dorsal roots branching off of their spinal nerve, what would be the result?
They would be unable to send out motor commands to muscles and glands that nerve controls
They would have loss of sensation and experience numbness in the area that nerve monitors
They would be paralyzed
Nothing would happen, dorsal root function is overrated
What is the function of cranial nerve 8 vestibulocochlear?
vision
face sensation and movements
hearing and balance
smell
What is the function of cranial nerve 2 optic?
vision
face sensation and movements
hearing and balance
smell
Damage to which of the following cranial nerves could result in death?
olfactory
trigeminal
vagus
optic
facial
What is the difference between spinal and cranial nerves?
spinal nerves are connected to the brain while cranial connect to the spinal cord
cranial nerves are connected to the brain while spinal connect to the spinal cord
spinal nerves are not as important as cranial nerves
cranial nerves control most of the body while spinal nerves only control the head

C8
C2
C6
C4
Tomas lost all movement and sensation in his shoulders. Which spinal root is damaged?
dorsal root
ventral root
both dorsal and ventral roots
What is a dermatome?
A region of skin that covers the head
A specific region of the body surface monitored by a spinal nerve
When trauma or compression of a nerve cause all sensory and motor to be lost
The name of cranial nerve #13
What do medical professionals use a dermatome chart for?
To determine how many tau tangles a person has in the brain from concussions
To see the color of each nerve or body part in a specific region
To diagnosis spinal nerve damage or infection
To see if the body is in "fight or flight" mode or in "rest and digest" mode
When we are under stress or in survival mode, what division of the autonomic nervous system is in charge of our involuntary functions?
sympathetic
parasympathetic
What is the purpose of reflexes?
To protect our body by maintaining homeostasis
To allow our brain to communicate with our body
To prepare our body for stressful situations
To repair our body when it gets damaged
Which of the following shows the components of a complex reflex arc in the correct order?
Stimulus, Motor Neuron, Sensory Neuron, Interneuron, Response
Stimulus, Sensory Neuron, Interneuron, Motor Neuron, Response
Response, Motor Neuron, Sensory Neuron, Interneuron, Stimulus
Interneuron, Motor Neuron, Sensory Neuron, Response, Stimulus
A simple reflex is different from a complex reflex arc because ...
simple reflexes do not need a stimulus
complex reflexes do not have a sensory neuron
simple reflexes do not have a interneuron and respond rapidly
complex reflexes do not have a motor neuron
When sensory and/or motor function are lost in a specific area of the body we call it a
Peripheral Nerve Palsy

both positive and negative feedback
neither positive and negative feedback
