This concept grounded in genetics, implying that our cells are pre-programmed to age and die. This theory stands in contrast to wear and tear theory. Which emphasiz...

Neuro endocrine theory(biological clock) of aging

NEURO ENDOCRINE THEORY OF AGING  According to Neuro endocrine theory the aging process is happening in hypothalamus,pituitary,and thyroid or the in regulatory action of these glands.Vladimer Dilman an internationally renowned endocrinologist put forward this theory in 1968.He found that there is considerable decline in the production of hormones in our body with increasing age,the secretion of thyroid,adrenel cortex,testis (males),ovary (females),pituitary (growth hormone) etc will falls.The production of aminoacids, peptides,monoamines enzymes etc also will decrease.it is also noted that the functional decline in neurons, Human endocrine system What are the functions of endocrine glands? Endocrine system is a group of glands,which produce most of all important hormones for our body.These hormones controls our growth development,moods,metabolism,reproduction etc. The glands includes Hypothalamus,pituitary,pineal(these3glands situated in brain),thyroid(neck)...
