People who are obese are at higher risk of arthritis or osteoporosis due to the increased load across the weight bearing joints‚ and increasing the stress on cartilage and ligaments. People who reduce their smoking and drinking will reduce the risks for low bone mass‚ low bone strength‚ and low body weight.

The senses transmit sensory information’s‚ in the form of electrochemical impulses‚ to the brain. Different forms of energy stimulate the sensory receptors – the nerve endings and cells that detect sensory information. The sensory receptors then initiate neural impulses. Sensation occurs when the neural impulses arrive at the cerebral cortex. Neural impulses that begin in the optic nerve are sent to the visual areas of the cerebral cortex‚ and we see objects. Each person’s unique perception results

The goblin shark has a distinctively long and flat snout‚ resembling a sword blade. The proportional length of the snout decreases with age.[17] The eyes are small and lack protective nictitating membranes; behind the eyes are spiracles. The large mouth is parabolic in shape. The jaws are highly protrusible and can be extended almost to the end of the snout‚ though normally they are held flush against the underside of the head. There are 35–53 upper and 31–62 lower tooth rows. The teeth in the main

not-toxic‚ non-corrosive‚ smooth‚ flexible‚ and low-density. 3. Muscles – Muscles look like bundles of pale pink tissue which pull the bone. Tendons - Tendons are shiny white tissues at the ends of the muscles that attach muscles to bones. Ligaments - Ligaments connect bones to other bones at joints. They look like a shiny white covering of the joint surfaces. Cartilage - Between the bones is another shiny white material that is slippery. This is cartilage‚ which helps the bones move without grinding
