Hormone | Definition, Function, & Types

 

Hormones

 These are manufactured substances which are released into the body fluids by one cell or a social occasion of cells and affect various cells of the body.

ENDOCRINOLOGY

This is the science stressed over the plans and components of the endocrine organs and the end and treatment of the issues of the endocrine structure.

Components of synthetic compounds

1. Help to control the inside environment by dealing with its engineered association and volume.

2. Transport substances through the cell film.

3. Expect a basic piece of improvement and progression.

4. Add to the fundamental patterns of spread,

    Planning, food of the nascent life form, and transport

    of newborn children.

5. Oversee assimilation and energy balance in the body.

Types

1. Close by synthetics: These have unequivocal neighborhood ramifications for the body.

Model: Acetyl choline, secretin and Cholecystokinin.

2. General synthetic substances: These impact body cells far away from their places of release. A few general synthetics impact all of the cells of the body, similar to advancement compound and thyroid substance. On the other hand, a couple of synthetic compounds impact simply on target cells since they have unequivocal receptors for the substance. for instance ACTH, estrogen, and progesterone.

Portrayal OF HORMONE

Considering THE CHEMICAL NATURE

1. Peptides

• Front pituitary synthetic compounds - GH, ACTH,

      prolactin

• Back pituitary synthetic compounds - ADH,

                oxytocin

• Islets of langerhans - Insulin, glucagon, somatostatin

• Thyroid organ - calcitonin

• Parathyroid organ - parathyroid compound

• Synthetic compounds of the GIT, i.e substance P

• Conveying and inhibitory synthetic compounds of the

      operational hub

• Ovaries - relaxin

2. Glycoproteins

  HCG, TSH, LH, and erythropoietin

3. Steroids

  (Cholestrol subordinates)

• Adrenal cortex (aldosterone, cortisol

  adrenal androgens)

• Ovaries (estrogen and progesterone

• Gonads (testosterone)

4. Aminoacids

(Tyrosine subordinate)

Thyroid organ - T3 - T4,

5. Amines

 (Tyrosine subordinates)

         • Acetylcholine, epinephrine,

  Nor-epinephrine and melatonin.
