Diencephalon: thalamus & Hypothalamus Flashcards
What is the primary function of the thalamus?
Relay sensory and motor information to the cerebral cortex.
Which sense does NOT pass through the thalamus?
Olfaction (smell) 👃.
What is the role of the hypothalamus?
Regulates homeostasis, controls the autonomic nervous system, and links the nervous and endocrine systems.
Which gland does the hypothalamus regulate?
Pituitary gland 🧪.
How does the thalamus contribute to motor function?
It relays motor signals from the cerebrum to the body and interacts with the basal nuclei.
