Additional Information
  • Hormones :
    • The chemical messengers, found in the gut are critical in regulating the intake of food and energy expenditure.
    • The body’s biggest hormone-producing structure, the gut secretes more than 20 various peptide hormones, some of these affect the eating pattern, sensation of pleasure during nibbling while some others target the brain to control appetite and so on.
  • Gastrin :
  • It is a peptide hormone primarily responsible for enhancing gastric mucosal growth, gastric motility, and secretion of hydrochloric acid (HCl) into the stomach.
  • It is present in G cells of the gastric antrum and duodenum.
  • Endocrine cells present in different parts of the gastro-intestinal tract secrete four major peptide hormones  -
    • Gastrin, Secretin, Cholecystokinin (CCK), and Gastric Inhibitory Peptide (GIP).
  • Gastrin acts on the gastric glands and stimulates the secretion of hydrochloric acid and pepsinogen.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. Lachrymal glands or tear glands are situated
