CORRECT SOLUTIONS (2026-2027
UPDATED) GRADED A+
A disease that damages the cells of the anterior grey horn will
a-inhibit autonomic regulation
b-cause paralysis or weakness in skeletal muscles
c-interrupt temperature recongnition
d-interrupt proprioception - ANSWER-b- cause paralysis or weakness in
skeletal muscles
After suffering a stroke, Mary finds that she cannot move her right arm. This
would suggest that the stroke damage is in the area of the ________ lobe. -
ANSWER-left frontal
An image of the cross-section of a spinal cord would show anterior (or
ventral) horns. What is in that region? - ANSWER-Cell bodies of motor
neurons
an unlearned and involuntary but predictable motor response to a stimulus
that is rapid and does not involve any processing by the brain is what
relflex? - ANSWER-spinal reflex
ANS - ANSWER-autonomic nervous system
Autonomic Dysreflexia - ANSWER-involves uncontrolled activation of
autonomic neurons, looks as if they are talking but they are not. They think
that they are talking to you, they are not though because they can not
control it. Say things that do not make sense.
,autonomic reflexes - ANSWER-smooth muscle regulation, heart and blood
pressure regulation, regulation of glands, digestive system regulation
autonomic vs somatic - ANSWER-autonomic (involuntary) and somatic
(voluntary)
Sympathetics - Lateral Grey horns of thoracic lumbar spine, sympathetic
trunk and preverterebral ganglia, short pre-ganglionic nerve; long post
ganglionic nerve; pre-ganglionic NT is Ach, Post gaglionic NT is EPI and NE,
Elevate HR and respiratory rate, Pupil dilate, vasoconstrict blood vessels to
digestive organs and vasodilate blood vessels to extremities, global
response, long acting
SOMATIC- slows you down, cranial nerves and sacral nerves, terminal
ganglia that lie near or ont he effector organ, long pre-ganlionic nerve, short
post ganglionic nerve, pre-ganglionic NT is Ach; Post ganglionic Ach, slows
down heart rate and respiratory rate, pupil constrict, vasodilate blood
vessels to digestive organs and vasoconstrict to extremities
brachial plexus - ANSWER-C5-T1, nerves to upper limb, neck, and shoulder
muscles
can any disruption in oxygen or glucose damage the brain? - ANSWER-yes
Cerebellum - ANSWER-A large structure of the hindbrain that controls fine
motor skills.
-Posterior to pons
- divides cerebrum and brainstem
-Connects brainstem via cerebellar peduncles
-functions to smooth and coordinate the intended motion that is happening
detected by the proprioceptors
, -functions in balance and coordination
-regulates tone and posture
Cerebrum - ANSWER-Largest part of the brain; responsible for voluntary
muscular activity, vision, speech, taste, hearing, thought, and memory.
Cholinergic vs. Adrenergic - ANSWER-Cholinergic- stimulates the
parasympathetic nervous system
Adrenergic- increases BP, bronchodialators, reduces intraocular pressure
CN 1 (1) - ANSWER-Olfactory
CN II (2) - ANSWER-Optic
CN III (3) - ANSWER-Oculomotor
CN IV (4) - ANSWER-Trochlear
CN IX (9) - ANSWER-glossopharyngeal nerve
CN V (5) - ANSWER-trigeminal nerve
CN VI (6) - ANSWER-abducens nerve
CN VII (7) - ANSWER-facial nerve
CN VIII (8) - ANSWER-vestibulocochlear nerve
