Special senses  [ EYE] These are organs in the body that performs specialised functions. They contain sensory receptors which receives sensory impulses and pass them to the appropriate centers in the brain for interpretation.   ➡️ Types of Sensory Receptors - based on the type of stimuli they detect: 1. Mechanoreceptors - pressure receptors, stretch receptors, and specialized mechanoreceptors involved  in movement and balance.  2. Thermoreceptors - skin and viscera, respond to both external and internal temperature.  3. Pain receptors - stimulated by lack of O2, chemicals released from damaged cells and inflammatory  cells.  4. Chemoreceptors - detect changes in levels of O2, CO2, and H+ ions (pH) as well as chemicals that  stimulate taste and smell receptors  5. Photoreceptors - stimulated by light ➡️ Distribution of Receptors in the body: Special Senses • mediated by relatively complex sense organs of the head, innervated by cranial ...

RETINA DETACHMENT  Retinal detachment describes an emergency situation in which a critical layer of tissue (the retina) at the back of the eye pulls away from the layer of blood vessels that provides it with oxygen and nourishment. Retinal detachment leaves the retinal cells lacking oxygen. The longer retinal detachment goes untreated, the greater the risk of permanent vision loss in the affected eye. The retina sends visual images to the brain through the optic nerve. When detachment occurs, vision is blurred. A detached retina is a serious problem that can cause blindness unless it is treated. The retina normally lies smoothly and firmly against the inside back wall of the eyeball and functions much like the film in the back of a camera. Millions of light-sensitive retinal cells receive optical images, instantly "develop" them, and send them on to the brain to be seen. If any part of the retina is lifted or pulled from its normal position, it is considered detac...
