Functions Of Muscle Attachments In The Body

By Janelle Burnett


Muscle attachments define the direction, speed and strength of movement. The attachment could either be indirect or direct depending on the functions of the joint at that point. Each category of attachment is defined by different features that must be understood. The distinction requires more scrutiny since some can only be differentiated using microscopic instruments.

You will identify an indirect attachment by the fact that muscles seem to end before getting to the bone. There is a mass of tendons separating muscles and the bone. This region is populated by fibrous bands, theicks and sheets. These sheets are identified as aponeurosis and provide the strength required to complete the connection between the bones and muscles.

The case of direct attachment appears as though nothing separates the muscle and the bone. The impression created is that the muscles have their origin in the bone. The collagen fibers between the bone and the muscle are microscopic. This separation can only be identified using microscopic instruments.

Muscles makes bones move in relation to others. The origin is always stationary while the insertion moves. There is a thick region that is located between the origin and insertion. This is referred to as the belly of that particular muscle. There are different types of muscles depending on their behavior and features in relation to their location in the body.

One distinct muscle type is the intrinsic muscle. It begins and ends in the belly. This means that its functions are significantly different and it can only be found in a certain part of human body. Action is what results when muscles move. The connections between one group of muscles and the other result in coordinated body action.

The body contains different categories of muscles explaining the behavior and functions of the body. The classes are antagonist, agonist, fixators and synergist. They work in distinct ways allowing actions to be coordinated.

The largest force in the human body is produced by agonist. They are thus described as prime movers. They allow basic movement to take place. They are assisted by synergist working in groups. One agonist requires more than one synergist. Synergists coordinate and restrict movement of agonist muscles. It is the synergists that offer direction to action in the body.

Antagonists oppose movement and force produced by agonist. They are responsible for determining the speed and range of movement in the body. This combination is referred to as an antagonistic pair because they work in opposite directions. This offers speed, coordination and direction to actions.

Fixator muscles are specific on the movement of bones. They ensure that the bones remain in place and do not make any movement that could damage the frame. Such restriction is necessary in preventing dislocations and excessive strain on any body part. It is the coordination of different types and categories of muscles that leads to proper and healthy movement.

There are different forms of muscle attachments depending on the level of movement at a particular part of the body. Classification allows a learner to identify and appreciate each attachment. More than one type of attachment may be manifest in a particular area.
