Pituitary Gland, Posterior Lobe (Neurohypophysis)

The posterior portion of the pituitary gland, which stores and releases oxytocin and vasopressin (ADH) produced by the hypothalamus.

Key Functions:

• Stores and releases oxytocin (involved in childbirth and lactation).
• Stores and releases vasopressin (Antidiuretic Hormone, ADH) (regulates water balance).
• Directly connected to the hypothalamus via the neurohypophyseal tract.

Interacting Systems & Components:

• Pituitary Gland (part of)
• Hypothalamus (produces hormones released here, specifically supraoptic and paraventricular nuclei)
• Oxytocin
• Vasopressin (ADH)
• Endocrine System (key component)
