ENDOCRINE GLAND Flashcards
Anterior Pituitary
Subdivided into:
○ Pars tuberalis
○ Pars
intermedia
○ Pars distalis
Posterior Pituitary Subdivided into:
○ Infundibular
stalk
○ Pars nervosa
MAJOR ENDOCRINE GLANDS (4)
○ Pituitary Gland
○ Pineal Gland
○ Thyroid Gland
○ Parathyroid Gland
Anterior and posterior part is directly
attached to the
HYPOTHALAMUS
Pituitary gland occupies a fossa of the
sphenoid bone called
SELLA TURCICA
Originate primarily on the
PARAVENTRICULAR NUCLEI
OXYTOCIN
Originate from the SUPRAOPTIC
NUCLEI
ANTIDIURETIC HORMONE (ADH)
Derived from an outgrowth of oral
mucosa (Rathke’s pouch)
ANTERIOR PITUITARY GLAND
○ Anterior portion
○ Darker stained
PARS DISTALIS (adenohypophysis)
○ Posterior portion
○ Lighter stained
PARS NERVOSA (neurohypophysis)
○ Delineation between pars distalis and
pars nervosa
○ Separates anterior and posterior
pituitary gland
○ Indicated by the symbol (*)
PARS INTERMEDIA
Connects the hypothalamus to the
pituitary gland
● PITUITARY STALK
PITUITARY GLAND
○ Divided into:
Divided into:
■ Anterior Pituitary
■ Posterior Pituitary
A fossa of the sphenoid bone
● SELLA TURCICA
Resembles the Central Nervous Tissue
(CNS)
● INFUNDIBULAR STALK and PARS NERVOSA
