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 Regulations

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