involved in the maintenance of homeostasis, the regulation of feeding, drinking and sexual activity , circadian rhythm, and emotional expression
hypothalamus
mesencephalon develops into the
midbrain
diencephalon develops into the
thalamus, epithalamus, hypothalamus, subthalamus
Theepithalamusis a small region of the diencephalon consisting of the _________, _______ nuclei, and _________.
Theepithalamusis a small region of the diencephalon consisting of the pineal gland, habenular nuclei, and stria medullaris thalami.
The pineal gland contains no true neurons, only
glial cells
