4. Final Structural Differentiation The pituitary gland achieves its final form, including the complete separation of anterior and posterior lobes, by the end of the first trimester The gland remains connected to the hypothalamus by the pituitary stalk, allowing it to integrate signals from the brain and regulate various endocrine functions in the body. This dual-origin structure and function are what make the pituitary gland a unique and critical component of the endocrine system, acting as a bridge between the nervous and endocrine systems.
