These chemicals are absolutely essential in many bodily functions including fluid balance, nerve conduction, muscle contraction (including the heart), blood clotting and pH balance. Other materials dissolved in plasma are carbohydrates (glucose), cholesterol, hormones and vitamins. Cholesterol is normally...
Nerve impulses also travel to the opposing leg muscle to inhibit contraction so that it relaxes (this pathway involves interneurons). The response is a quick muscular jerk that does not involve your brain. Humans have lots of hardwired reflexes like this, but as tasks become more complex, the...
Five muscles surround the abdomen. The wall of the abdomen is partly bone but mainly muscle. The muscles form a flexible but firm wall to keep the abdominal organs safe from injury and help them maintain their positions in the erect posture. ...
