Muscle Tissue, Function & Levers

The go across tissue has four main properties; Excit baron, Contractibility, Extensibility and snap bean. Excitpower; The ability to serve to stimuli. Contractibility; The ability to contract. Extensibility; The ability to stretch without causing a tear. Elasticity; The ability to be able to return to typical shape. enchantment contraction is taking place the muscular corpse performs 3 functions; Motion, Heat Production and Maintenance of posture. Motion; The ability of existence able to move e.g. walking or running. However, with head you must(prenominal) know about levers.

First-class; when the muscle force and repellent force is on different slopes of the fulcrum e.g. the head resting on the vertebral column. As the head is r aised, the facial portion of the skull is th! e resistance, the fulcrum is amid the book of maps and occipital bone, and the effort is the contraction of the muscles of the back. Second-class; when the muscle force and resistive force act on the same side of the fulcrum, with the muscle force acting through the take aim continuing than that through which the resistive force acts - e.g. raising the body up onto the toes. The body is the resistance, the ball of the foot is the fulcrum, and the effort is...If you neediness to get a full essay, order it on our website: OrderCustomPaper.com
