How does the way in which the hypothalamus communicates with the anterior and posterior pituitary glands differ? How does this reflect the functional differences of the anterior and posterior pituitary glands?

Explanation:

Hyposis

The pituitary gland or pituitary gland is an endocrine gland that secretes hormones responsible for regulating homeostasis including the tropic hormones that regulate the function of other glands of the endocrine system, depending in part on the hypothalamus, which in turn regulates the secretion of some hormones. It is a complex gland that is housed in a bone space called the Turkish sphenoid bone chair, located at the base of the skull, in the middle cerebral fossa, which connects with the hypothalamus through the pituitary stem or pituitary stalk. It has an oval shape with an anteroposterior diameter of 8 mm, transverse of 12 mm and 6 mm vertically, on average it weighs 500 milligrams in the adult man, 600 mg in the woman and in which they have had several deliveries, up to 700 mg. 2

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
