2. Introduction
● Group of biological structures closely work with
nervous system
● *Ductless
● Well supplied of blood vessels
● Secrete *harmones direct to bloodstream
1) *Duct - channels in which harmons secret their
secretions.

3. Types
1. Pituitary glands
2. Thyroid glands
3. Adrenal glands
4. Pancreas glands
5. Gonads

4. 1. Pituitary glands - master glands
● Its secretes control over; Adrenal, Thyroid, Gonads
● Half inch diameter but control wide range of body
functions
● Lies in base of brain just below hypothalamus
● Secrete growth hormone Important in physical
development
● Deficiency of its secretions results Dwarfism 4

5. 2. Thyroid glands
● Lies side of Adam’s Apple, secrets hormones -
thyroxine
● Conjunction with pituitary, affect metabolism and
physical growth
● High thyroid output and Low thyroid outputs
● Affect structure and function of nervous system
● Hypothyroidism - Cretinism in children 5

7. 3. Adrenal glands
● Lies upper end of both kidneys
● Endocrine Adrenal cortex secrete hormones play
important role in salt and carbohydrate metabolism
● In injury to this part treated by these hormones
● Adrenal medulla Not true endocrine
● Epinephrine - prepare body for emergency work, fast
heart beat 7

8. 4th. The Pancreas
● Situated under the stomach
● It has Insulin hormone to maintain the level of blood
sugar
● When insulin decreases (liver releases sugar high)
● When insulin increases stored in liver (sugar low)
● When insulin produce insufficiently it enters through
kidneys and controlled by Injection of Insulin 8

9. 5th. The Gonads
● Testis for male and Ovaries for female
● Male hormones (Androgen) & female hormones
(estrogen)
● Secondary sex characteristics are features that
appear during puberty in humans(features such as
pubic hair, breast development in females, and
beards in males.)

● Progesterone, important in Menstrual Cycle and in
maintaining the uterus in a quiet state during
development of the fetus during pregnancy.
