BIOLOGY
Lobes-
• Adenohypophysis or Anterior pituitary
• Neurohypophysis or Posterior pituitary.
•Adenohyposis consists of three
divisions-
-Pars distalis
-Pars tuberalis
-Pars intermedia

BIOLOGY
•Adenohypophysis arises from the roof
of pharynx as an upward outgrowth
called Rathke’s pouch.
•Neurohypophysis arises from the
hypothalamus as a downward
outgrowth.
•Adenohypophysis consists of two types
of cells
-Chromophobe cells (about 50%)
-Chromophil cells (about 50%)

BIOLOGY
•Chromophobes-
•do not possess granules,stain poorly,
•non secretory, precursors of
chromophils.
•Chromophils contain a large number
of granules and are darkly stained.
•Based on staining property,
-Acidophilic cells or Alpha cells
(about 35%)
-Basophilic cells or beta cells(about
15%)

BIOLOGY
•Chromophils are classified into five
types(secretory basis)
1. Somatotropes - GH
2. Corticotropes - ACTH
3. Thyrotropes - TSH
4. Gonadotropes - FSH & LH
5. Lactotropes - Prolactin

BIOLOGY
•Somatotropes and Lactotropes are
acidophils while others are basophils.
•The secretion of adenohypophysis is
regulated by Releasing and Inhibitory
hormones secreted by the
hypothalamus.

•The Releasing and Inhibitory
hormones are-
-Growth hormone/ Somatotropin
releasing hormone (GHRH or SRH)
-Growth hormone Release Inhibitory
hormone(GHRIH) or Somatostatin
-Thyrotropin Releasing hormone(TRH)
-Corticotropin Releasing hormone

functions:
1. Growth Hormone(GH) or
Somatotropic hormone(STH)
- Stimulates growth of the
body(bone, muscles etc)
- Hyposecretion

Neurohypophysis:
•It is made up of neural type of cells
called pituicytes and unmyelinated
nerve fibres.

BIOLOGY
•The pituicytes act as supproting
cells and do not secrete any
hormone.
•The unmyelinated nerve fibres come
from supra optic and paraventricular
nuclei of hypothalamus through
pituitary stalk.
•Neuohypophysis does not secrete
any hormone but stores and releases
hormones secreted by
neurosecretory cells hypothalamus.

Hormones of Neurohypophysis and
their functions:
1. Oxytocin:
• Secreted by paraventricular
nucleus of hypothalamus.
• Childbirth & facilitating delivery.
• Contracts smooth muscle fibres of
mammary glands and stimulated
release milk after childbirth.

Drug and Alcohol Abuse
•Drug – A chemical which , when
taken in some way alters the body
functions.
•Intake of drug for a medical purpose
to treat body’s disorder is known as
its “Use”.
•Intake of drug for a non-medical
purpose and in amount, strengths
and manner or frequency that impairs
physical and mental function is
called “Abuse”.

Alcohol Abuse:
•Alcoholism is a state of
continued excessive use of
alcohol and addiction to it.
•Alcohol - quickly absorbed in the
stomach and upper part of the
small intestine and reaches
tissues in a few minutes.

a sedative, analgesic and
anaesthetic agent.
