Pituitary
gland (hypophysis) -- known as the Master Gland because of the
hormonal control it exerts on many other glands
Study the diagram of the pituitary gland
noting the relationship among the anterior and posterior
parts, the vascular supply, and the hypothalamus of the brain.
Name two basophils and two
acidophils and give the target cells for their secretions.
Examine a section of
pituitary and identify the
anterior pituitary, the posterior pituitary,
and the intervening pars intermedia with cysts representing
remnants
of Rathke's pouch. The latter structure may be
better seen on slide 122. The pars intermedia is poorly developed in
humans. Note the abundance
of large capillaries among the clumped, epithelial cells in the
anterior pituitary.
The staining property of
chromophobes is believed to have what functional significance?
Hormones stored in the axons of the pars nervosa are synthesized in
cell bodies located where?
