ENDOCRINE SYSTEM Flashcards
A small BEAN-SHAPED GLAND at the base of the brain, located in a bony cavity in the base of the skull – the sella turcica.
PITUITARY GLAND
pituitary gland is located in a bony cavity in the base of the skull called
SELLA TURCICA
_______ control the other endocrine glands and influence growth, metabolism, and maturation
SECRETIONS
pituitary gland is divided into:
ANTERIOR PITUITARY (adenohypophysis)
POSTERIOR PITUITARY (neurohypophysis or pars nervosa)
anterior pituitary
adenohypophysis
posterior pituitary
neurohypophysis or pars nervosa
a thin cell layer BETWEEN the PARS DISTALIS and the NEUROHYPOPHYSIS.
PARS INTERMEDIA
Thin zone of basophilic cells
PARS INTERMEDIA
pars intermedia is a thin zone of
basophilic cell
surrounds the NEURAL STALK.
PARS TUBERALIS
the pars tuberalis surrounds the
NEURAL STALK
Consist of basophilic secretory cells
PARS TUBERALIS
pars tuberalis consist of
BASOPHILIC SECRETORY CELLS
Consist of secretory cells called CHROMOPHILS (include acidophils and basophils) and CHROMOPHOBES
PARS DISTALIS
pars distalis Consist of secretory cells called
CHROMOPHILS & CHROMOPHOBES
secretory cells that include ACIDOPHILS and BASOPHILS
CHROMOPHILS
the LARGEST PART of the hypophysis.
PARS DISTALIS
pars distalis is the largest part of the
HYPOPHYSIS
located at the BASE OF HYPOTHALAMUS from which extends the pituitary stalk or infundibulum
