the anterior pituitary. these various parts are separated by meningial membranes, suggesting that the pituitary of other vertebrates may have formed from the fusion of a pair of separate, but associated, glands. most armadillos also possess a neural secretory gland very similar in form to the posterior pituitary, but located in the tail and associated with the spinal cord. this may have a function in osmoregulation. there is a structure analogous to the pituitary in the octopus brain. intermediate lobe although rudimentary in humans (and often considered part of the anterior pituitary), the intermediate lobe located between the anterior and posterior pituitary is important to many animals. for instance, in fish, it is believed to control physiological color change. in adult humans, it is just a thin layer of cells between the anterior and posterior pituitary. the intermediate lobe produces melanocyte-stimulating hormone (msh), although this function is often (imprecisely) attributed to the anterior pituitary. the intermediate lobe is, in general, not well developed in tetrapods, and is entirely absent in birds. location of the pituitary gland in the human brain pituitary and pineal glands the arteries of the base of the brain. mesal aspect of a brain sectioned in the median sagittal plane. pituitary pituitary gland cerebrum.inferior view.deep dissection.
