Diencephalon Flashcards
How many pairs of nuclei are in the thalamus?
26
Why is it called diencephalon?
it refers to two components or complimentary patterns of the brain
functions of thalamus (4)
switching station for all sensory inputs (except olfactory), modulates motor output, role in consciousness, visual/spatial processing system
The thalamus is the gateway to the cortex for what?
sensory information
function of the hypothalamus
regulates ANS, body temperature, hunger, sleep-wake cycle
What works closely with the hypothalamus in endocrine functions?
pituitary gland
What works closely with the hypothalamus in the expression of emotion?
the limbic system
habenula
principle structure of the epithalamus
function of the subthalamus
provides feedback and feedforward circuits of the thalamus and basal ganglia
pituitary gland
master gland of endocrine system
function of pituitary gland
regulates growth, reproductive activities, metabolic processes
function of pineal gland
role in sexual and hormonal functions, sleep-wake cycle
posterior commissure
connects right and left diencephalon
anterior commissure
connects olfactory bulb to amygdala
interthalamic adhesion
allows for communication between two thalamic lobes
septum pellucidum
sheath-like covering that extends over medial wall of lateral ventricles
What migrates peptides from the hypothalamus to the pituitary gland?
hypothalamohypopophyseal tract
What is the hypothalamus/pituitary problem where one dumps out too much fluid?
diabetes insipidus
What is the hypothalamus/pituitary problem where one retains too much fluid?
syndrome of inappropriate antidiuretic hormone secretion (SIADH)
