cerebellum
what does the diencephalon link
cerebrum with brain stem
which cranial nerve is not myelinated
cranial nerve #1
TRUE OR FALSE: the mamilary bodies are involved in lactation
false
what does the cerebellum coordinate and is covered by
body movement and the cerebellar cortex
JoJo begins to experience mood swings and disturbed thirst and hunger. Imaging studies indicate that a brain tumor is the likely cause of these disorders. In what part of the brain is the tumor most likely located?
hypothalamus
with which part of the brain do we link our endocrine and central nervous system with
hypothalamus
role of anterior cingulate
impulse control and decision making
Role of middle peduncle?
input from cortex via pons
what is nucleus accumbent involved in and is regulated by
involved in reward and addiction and is regulated by dopaminergic projections
role of the nuclei and tracts in pons
involved with reparation and relays info to and from cerebellum
function of the hippocampus
located in limbic system(temporal lobe) and stores/recalls longer term memory
role of the poutine respiratory center
located in pons and interacts with medulla respiratory center to smooth respiration rhythm
what does the pons link to?
mesencephalon, diencephalon, cerebrum, and spinal cord
nickname and function of mesencephalon
midbrain and is a part of brainstem that processes sight, sound, and associated reflexes
what does basal nuclei determine
movement and helps cerebellum stabilize it
No sensory information, with the exception of _______, reaches the cortex without prior processing in the thalamus.
olfaction
what sense does the maxillary bodies in the hypothalamus process
olfaction
which cranial nerve is serape from sensory area
olfaction
accountant patient has tumor in
orbitofrontal cortex
the cerebrum matches motor _____ to motor ____ and to then adjust the motor ____
plan, movement, plan
The _____ and the cerebellum act in synchrony to regulate the movements of the limbs.
pons
role of Purkinje cells
process and communication in cerebellar cortex
the posterior group includes pulvinar, lateral and medial. which process sensory, visual and auditory
pulvinar: sensory lateral: visual medial: auditory
what is the tegmentum
red nucleus with many blood vessels involved in subconscious motor control
via what nucleus does the amygdala receive input and send output
send input via basolateral nucleus and sends output via central nucleus
what does the third ventricle in the thalamus do
separate left and right thalamus
what control is the pons involved in?
somatic and visceral motor control
functions of hypothalamus include
subconscious control of skeletal muscles, autonomic function, coordination of nervous and endocrine system, secretes hormones, drives sleep/hunger/thirst, regulates body temp
what are the two pairs of sensory nuclei in tectum
superior and inferior colliculus
what relays info like pain reflex and perception from basal nuclei and cerebral cortex
thalamus
The cerebellar hemispheres are separated at midline by ____
vermis
what is superior colliculus involved in
visual reflexes
what is the fornix
white matter tract connecting hippocampus w hypothalamus
function of basal nuclei
-help initiate and terminate movements -suppress unwanted movements -regulate muscle tone -control subconscious contractions of skeletal muscles
what hormone does hypothalamus secrete
ADH
Damage to the left superior colliculi would interfere with the reflex ability to _____. a. turn the head to the left b. voluntarily move the right arm c. turn the head to the right d. react to loud noises originating on the left e. maintain proper posture
C
which lobes does the primary fissure separate
anterior + posterior
where does the anterior and posterior lobes get their info from
anterior gets info from spinal cord and posterior gets it from cortex
what is the branched white matter left by the purkinje cells called
arbor vitae
what is inferior colliculus involved in
auditory reflexes
Which of the following is not a function of the limbic system? a.Contains cerebral and diencephalic components b.Functions in maintaining homeostasis in cold weather c.Located between the border of the cerebrum and diencephalon d.Links conscious functions of the cerebral cortex with unconscious functions of the brain stem e.Functions in emotions, learning, and memory
b
role of cerebral peduncles
carry sensory and motor info to and from brain
the amygdala controls _____
emotions
