2. Brief Introduction
ENDOCRINE SYSTEM
Vertebrate hormones regulate
such diverse activities as;
Growth
Development
Reproduction
Metabolic Rate
Fluid Balance
Blood Homeostasis
And Coping with stress

Hormones are Regulated by the Glands
In this Presentation, Mainly we are going to
explain about the Classical Human Endocrine
glands

 Controls an immense
amount of our bodily
functions.
 Located in the middle of the
base of the brain and
encapsulates the ventricle
portion of the third ventricle.
Hypothalamus

5. Your Logo
• Located in the center of the skull.
• the size of the Pituitary gland is about the size of a
pea.
• Important link between the nervous system and
the endocrine system and releases many
hormones which affect
• Growth
• sexual development
• metabolism
• system of reproduction
• . The pituitary gland has two distinct parts, the
anterior and the posterior lobes.
• This gland was once believed to be the main
controlling gland of the body.
• The pituitary gland then makes hormones of its
own in answer to the body's needs.
Pituitary gland

6.  the "third eye" by ancient people.
 The pineal does contain a complete map of the
visual field of the eyes, and it plays several
significant roles in human functioning.
 center for the production of the hormone
melatonin.
 regulates daily body rhythms, most notably the
day/night cycle, prevents jet lag, is implicated in
seasonal affective disorder, coordinates
fertility, and allows for deep restful sleep
patterns
 Connect to the brain and nerves system through
a complex network of bidirectionnel links.
Pineal gland

7.  Shaped like a butterfly.
 and usually weighs less than one ounce.
 The thyroid cartilage covers the larynx
and produces the prominence on the
neck known as the "Adam's Apple".
 Controls the rate at which the body
produces energy from nutrients.
 If the body does not get enough iodine,
the thyroid gland cannot produce a
proper amount of hormones for this
conversion process.
Thyroid gland

8.  small endocrine glands in the neck that
produce parathyroid hormone.
 Humans have four parathyroid glands.
 located in variable manner on the
posterior surface of the thyroid gland,
or, in rare cases, within the thyroid
gland itself or in the chest
(mediastinum) or even the thymus.
 control the amount of calcium in the
blood and within the bones.
Parathyroid gland

9.  Forms in a part of the immune system.
 It is situated in the upper part of the chest.
 made up of two lobes that join in front of
 function is to transform lymphocytes (white
blood cells developed in the bone marrow) into
T-cells (cells developed in the thymus)
 The thymus enlarges from about the 12th
week of gestation until puberty.
 transported to various lymph glands.
 play an important part in fighting infections and
disease.
Thymus gland

10.  found on top of both of
the kidneys.
 The center of the
adrenal consists of the
medulla which
produces epinephrine
and norepinephrine.
Adrenal gland

11. • pancreas has two main functions:
• to produce pancreatic
endocrine hormones, which
help regulate many aspects of
our metabolism
• to produce pancreatic
digestive enzymes
Pancreas

12. o produce a female hormone
and it called as estrogen.
o store female sex cells, or
“ova.”
Ovary

13. Testes is male gonads.
Suspended within a sac of skin called the
Scromtum.
It is composed of seminiferous tubles.
It have two main function:
 Formation, Developmet and excretion
of sperm.
 The secretion of testosteron.
Testes

14. Conclusion
Hormones are Regulated
by the Glands
Growth
Development
Reproduction
Metabolic Rate
Fluid Balance
Blood Homeostasis
And Coping with stress
Endocrine system is the system
of glands that produce
endocrine secretions that help to
control bodily metabolic activity
