Which gland is known as biological clock

These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi and cyanobacteria.Definition of biological rhythm cyclic change in level of bodily chemical or function number of physiological processes with rhythm over 200 types of biological clock control internal and external( endogenous and exogenous) endogenous control where the scn controls the sync of the clock exogenous controlThe pineal gland is controlled by a brain structure known as the suprachiasmic nucleus, located at the base of the brain, dr.The pituitary gland releases fsh to stimulate eggs to grow and mature.A biological clock is an internal timing system which continues without any external time cues and controls the activities of plants and animals.a biological clock is only really an advantage if it means the organism can anticipate environmental changes.

Sunlight and the temperature are the external cues, on which the biological clock partly depends.It is located on the dorsal side of forebrain.The main cog in the human biological clock is the suprachiasmatic nucleus (scn), a group of nerve cells in a region at the base of the brain called the hypothalamus.The suprachiasmatic nucleus is known as the mind's clock, because it coordinates body rhythms in response to changes in lighting that are detected by the eyes.The terms on which the biological clock depends.

Its 20,000 nerve cells sit in the middle of the brain above the back of the eyes and on top of a structure called the hypothalamus.Pineal gland is a small, rounded and reddish brown gland present at the dorsal side of forebrain.On the whole, biological clock are defined by three criteria:• these go down into the pituitary gland • pituitary gland releases acth • acth goes into the adrenal gland and triggers the release of glucocordionds.
