Sodium and potassium are important within the nervous impulse; without those living organisms would not be able to send an impulse across a nerve‚ therefore we would not be able to survive. This is because‚ for depolarisation to take place‚ firstly there must be a resting potential at -70mv‚ this is acquired by the sodium-potassium pump‚ which pumps

joint. The tight space between this fibrous band and the wrist bone is called the carpal tunnel. The median nerve passes through the carpal tunnel to receive sensations from the thumb‚ index‚ and middle fingers of the hand. Any condition that causes swelling or a change in position of the tissue within the carpal tunnel can squeeze and irritate the median nerve. Irritation of the median nerve in this manner causes tingling and numbness of the thumb‚ index‚ and the middle fingers -- a condition known

Components * There are three parts to the muscular system: * the muscles themselves‚ * nerve tissues and connective tissues. * The connective tissues (tendons) attach the muscles to the skeletal system. * The nerve tissues conduct the electrical impulses that control the muscles. Muscle characteristic * irritability‚: denotes how a muscle responds when it receives an electrical impulse or is damaged * contractibility‚: is how muscles move; they shorten‚ then relax to control

VITAMINS AND MINERALS Vitamins and minerals make people’s bodies work properly. Although you get vitamins and minerals from the foods you eat every day‚ some foods have more vitamins and minerals than others. Vitamins fall into two categories: fat soluble and water soluble. The fat-soluble vitamins — A‚ D‚ E‚ and K — dissolve in fat and can be stored in your body. The water-soluble vitamins — C and the B-complex vitamins (such as vitamins B6‚ B12‚ niacin‚ riboflavin‚ and folate) — need to dissolve

pairs of nerves branch from the CNS. 12 of the pairs branch from the brain and the other 31 nerve pairs branch from the spinal cord. The 43 pairs of nerves stretch throughout the body to form the peripheral nervous system. The CNS is the coordinator and “decision maker” in the nervous system‚ and the PNS is sending the information as sensory input and receives instructions as motor output to muscles and glands. The autonomic nervous system has some elements in the CNS and it shares some nerves with

The biggest controversy of the deaf community has been the topic of a cochlear implant. The debate is centered around the expense‚ risk and idea of the implants causing deaf people to distance themselves from the deaf community rather than emerging themselves. This is due to the cochlear implants ability to provide a sense of sound to the deaf individual. It is only used when a hearing aid is not strong enough to provide adequate function. The cochlear implant involves a lot of time to consider the
