Human Anatomy The body in movement - Essay Example There are 206 bones in the human body which have roughly 700 muscles pulling on them. This paper aims at using daily human activities to discuss human and anatomy and the body in movement. Skeletal muscles can be said to be the only voluntary tissue in the human body. Every movement that a human being initiates voluntarily cannot take place in the absence of the skeletal muscles. Skeletal muscles perform the function of contracting in order to make various parts of the body to move closer to the bone they are attached to. Most skeletal bone served two adjustment bones that are connected via joints. Therefore, skeletal muscles can be said to be for the purpose of moving parts of these adjacent body bones close to each other. As a result of this involvement it can be said that skeletal muscles are vital for the movement in human beings. This is because most movements in the bodies of human beings always involve movement of bone joints (Palastanga, Field, and Soames 77). Skeletal muscles are not only essential for voluntary movements, but the involuntary ones too. In most cases, skeletal muscles do not manage to make the human body by themselves. The most common occurrence is that they work together in order to make human bodies move in certain ways. When a muscle initiates a certain movement in the human body, it is always referred to as the prime mover. The prime mover always works together with an opposing muscle that has the main responsibility of availing an opposite effect on the same bones. For instance, the biceps brachii muscle flexes the human hand at the elbow, while the triceps brachii muscle opposes these forces at the same point (Palastanga, Field, and Soames 89). However, there are some muscles that act in support of the body movement initiated by another muscle. Such muscles are referred to as Synergists and have the main purpose of stabilizing the body movement. For this
