Hypothalamic-Pituitary Axis

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

The hypothalamus, per Bio 2845, integrates nervous and endocrine control by synthesizing hormones that govern the pituitary, coordinating the body's hormone output from a single point.

Show

Hypothalamic releasing hormones travel through a dedicated portal system directly to the anterior pituitary, bypassing circulation.

Watch for

The hypothalamus is a brain structure that also functions as an endocrine organ — the two roles are not separate.
