⟨⟨HORMONES & THEIR FUNCTIONS ⟩⟩

1. Growth hormone (GH) Or somatotropic hormone (STH)
Function ~ stimulates growth by stimulating protein synthesis.

2. Thyroid stimulating hormone (TSH)
Function ~ stimulates thyroid secretion.

3. Adrenocorticotropic hormone (ACTH)
Function ~ stimulates the production of of steroids by adrenal cortex.

4. Gonadotropic hormones

(i) follicle stimulating hormone (FSH)
Function ~ stimulates gamate, production, secration of s*x hormones, development of follicles.

(ii) interstitial cell stimulating hormone ( ICSH) or luteinising hormone (LH)
Function ~ stimulates the leydig cells of te**is and induces secretion of testosterone. stimulates development of Corpus luteum and ovulation in female.

5. Luteotropic hormone ( LTH) or prolactin
Function ~ stimulates the growth of mammary glands, lactation and maintenance of Corpus luteum.

6. Melanocyte stimulating hormone
Function ~ controls dispersal of melanophores , in man it is doubtful.

7. Oxytocin
Function ~ stimulates secretion of milk from mammary glands ; causes contraction of uterus at the time of child birth.

8. Antidiuretic hormone or ADH (vasopressin)
Function ~ stimulates the nephrons for reabsorption of water.
Stimulates contraction of smooth muscles , blood vessels and causes rise in blood pressure.

9. Thyroxine (T4) and triiodothyronine (T3)
Function ~ control metabolism , regulate body temperature by calorigenic action.

10. Thyrocalcitonin (TCT)
Function ~ controls calcium (Ca++) level in blood , Check osteoporosis .

11. Parathormone
Function ~ maintains proper level of calcium and phosphorus by regulating renal action , thus , controlling calcium and phosphate amount in bones.

12. Insulin (from β cells)
Function ~ stimulates metabolism of carbohydrates. Influences the storage and utilization of sugar , inhibits hepatic gluconeogenesis stimulates glycogenesis.

13. Glucagon (from α cell)
Function ~ influences the enzymatic action of phosphorylase , controlling glycogenolysis in tha liver and muscles ; increases the amount of sugar in blood.
Antagonistic to insulin , inhibits glycogenesis.

14. Somatostatin(ss)
Function ~ suppresses the release of hormones from the pancrease and digestive track.

15. Pancreatic polypeptide
Function ~ inhibits the release of digestive secretion of the pancrease.

16. Adrenaline (epinephrine) and noradrenaline (Norepinephrine)
Function ~ Regulates heart beat , blood pressure , sympathetic nervous system , contraction of involuntary muscles of lung , eyes , gut etc. , Production of blood , flow of saliva and sweat under emotional state.

17. Adrenocorticoids
Function ~ regulate water and electrolyte balance, regulate fat, protein and carbohydrate metabolism; stimulate development of male and female secondary s*xual characters.

18. Testosterone (leydig's cells)
Function ~ affects the normal development and functions of secondary s*xual organs and characters in male.
~ stimulate formation of sperms.

19. Estrogen (graafian follicles )
Function ~ Affects development and maintenance of secondary s*xual characters in female.
~ stimulate maturation of ova.

20. Progesterone ( o***y and Corpus luteum )
Function ~ stimulates uterus for pregnancy, implantation and formation of placenta, also stimulates mammary glands.

21. Relaxin ( Corpus luteum )
Function ~ relaxes ligaments of pelvic girdle at the time of birth.

22. Human chorionic gonadotropin or HCG (placenta)
Function ~ pravints disintegration of the Corpus luteum and maintains progesterone production.

23. Serotonin
Function ~ Helps in vasoconstriction of blood vessels.

24. Melatonin
Function ~ Reduces quantity of FSH and LH, Acts as anti gonadotropic hormone.

25. Thymosin
Function ~ regulates growth, stimulates proliferation of lymphocytes and also hastens s*xual maturity.

🔷♻️Animal Tissue♻️🔷

The tissue found in animals have comparatively some different properties than the plant tissue.

♦️Types of Animal Tissue
Animal Tissues are divided as −

➖Epithelial Tissue
➖Connective Tissue
➖Muscular Tissue
➖Nervous Tissue

🍪Epithelial Tissue
➖Epithelial tissues are the covering and protective tissues in the animal body.
➖Epithelial tissue covers almost all organs and cavities within the body.
➖Epithelial tissue also forms a barrier to keep different body systems separate.
➖Epithelial tissue cells are closely packed (as shown in the image given above) and form a continuous layer.

🍪Connective Tissue
➖Connective tissues are made up of the cells those are separated by non-living material, and known as an extracellular matrix.
➖This matrix could be either liquid or rigid.
➖Connective tissues are further divided as −
* Fibrous connective tissue
* Skeletal connective tissue and
* Fluid connective tissue

➖Tendons are the example of fibrous connective tissue.
➖Bone is an example of a skeletal connective tissue.
➖Bone forms the framework and provide supports to the body.
➖Blood is an example of fluid connective tissue.
➖Blood has a fluid (liquid) matrix known as plasma.
➖In plasma, the red blood cells (RBCs), the white blood cells (WBCs), and the platelets are remaining suspended.

🍪Muscular Tissue
➖Muscular tissue largely consists of elongated cells, and also known as muscle fibers.
➖The muscular tissue is accountable for the movements in our body.
➖The muscular tissue contains special proteins known as contractile proteins; and this protein helps in contraction and relaxation and supports free movement.

🍪Nervous Tissue
➖The brain, spinal cord, and nerves all are composed of the nervous tissue.
➖Cells of the nervous tissue are extremely particular and sensitive for being stimulated and then transmitting the stimulus swiftly from one place to another within the body.
➖The cells of nervous tissue are known as nerve cells or neurons.
➖Nerve impulses allow us to move our muscles whenever we want to do so.
