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
