List the hormones of the anterior lobe of the pituitary gland?

Explanation

The anterior lobe of pituitary secretes six tropic hormones such as growth hormones (GH) , thyroid stimulating hormone (TSH) adreno corticotropic hormone (ACTH) follicle stimulating hormone (FSH) luteniizing hormone (LH) luteotropic hormone (LTH) and melnocyte stimulating hormone (MSH) (in lower animals only).The posterior lobe of pituitary secretes the hormones namely vasopressin and oxytocin
Hormones of Adenhypophysis:
(i) . Growth hormone (GH) :
1. It is also known as somatotropic hormone (STH) or Somatotropin
2. Growth hormone promotes growth of all the tissues and metabolic process of the body.
3. It influnces the metabolic of carbohydrates,proteins and lipids and increases the rate of protein biosynthesis in the cells. it simulates chondrogenesis (cartilage formation) . osteogenesis (bone formation) and helps in the retention of minerals like nitrogen potassium phosphorus ,sodium etc. in the body
II) Thyroid stimulating hormone (TSH) or thyrotropin:
TSH is a glycoprotein hormone which stimulates the thyroid gland to secrete tri-iodothyronine `(T_2)` and thyroxine `(T_4)` TSH secretion is regulated by negative feedback mechanism
III) Adreno cortico trople hormone (ACTH) :
1. ACTH is a peptide hormone that stimulates the adrenal cortex to secrete glucocorticoids and mineralocorticoids
2. It stimulates melanin synthesis in melanocytes induces the release of fatty acids from adipose tissues and stimulates insulin secretion.
3. ACTH secretion is regulated by negative feedback mechanism
(IV) Follicle stimulating hormone (FSH) :
1. FSH is a glycoprotein hormones which regulates the functions of the gonads (overy and testis)
2. In males FSH along with androgens acts on the germinal epithelium of seminiferous tubules and stimulates the production and release of sperms (spermatogenesis )
3. In females FSH acts on the ovaries and brings about the development and maturation of graffian follicles
(V) Luteinizing hormone (LH) :
1. LH is a glycoprotein hormone which is also known as interstitial cell stimulating hormone (ICSH)
2. In males ICSH acts on the interstitial cells of testis to produces the male sex hormone, testosterone,Im female
3. LH along with FSH matures the ovarian follicles
4. LH independently induces ovulation maintains the corpus luteum and promotes synthesis release of ovarian hormones
5. FSH and LH are collectively reffered as gonadotropins
(VI) Luteotropic hormones (LTH):
1. LTH is also called luteitropin or lactogenic hormones or prolactin or mammotropin
2. It is a protein hormone which stimulates milk secretion after the child birth in females.
