New cards

Hypothalamus

A neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward.

New cards

pituitary gland

The endocrine system's most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.

Brainstem

Midbrain, pons, medulla oblongata (superior to inferior)

New cards

Midbrain

A small part of the brain above the pons that integrates sensory information and relays it upward.
