Question

Why is posterior pituitary known as storage, releaser centre?

Answer 1

The posterior pituitary or neurohypophysis is posterior lobe of the pituitary gland. The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. Two hormones are related to the posterior pituitary: oxytocin and vasopressin. These hormones travel along the axons into storage sites in the axon terminals of the posterior pituitary. In response to signals from the same hypothalamic neurons, the hormones are released from the axon terminals into the bloodstream. The hypothalamus sends hormones directly to the posterior lobe via the nerves, and then the pituitary gland releases them. That's why, posterior pituitary is meant for storage ans release of the stored contents.
