The strength, speed and direction of movement are determined by muscle attachments. They come either as direct or indirect which affects how they function and support other body parts. Understanding these differences allows one to appreciate the uniqueness of each action. You will require magnifying instruments to identify these differences.
An indirect attachment is characterized by muscles that seem to end just before the point where the bone should attach. The bone and muscles are separated by tendons. These tendons are made of sheets, theick or fibrous bands. The sheets are referred to as aponeurosis. They are connective in nature and strong enough to hold the bone and the muscles together.
A direct attachment is characterized by an apparent connection between the bone and muscles. The bone seems to be the origin of all the muscles around without a tendon space in between. There are fibers in between, but they can only be seen using a microscope. These fibers are collagen in nature.
The essence of muscles is to facilitate movement of bones in relation to others that are attached. Muscles are characterized by a stationary origin and moving insertion. The region separating the insertion and the origin directs movement and is referred to as the belly. Different parts make movements depending on their functions. This necessitates the presence of different muscle in particular areas.
The intrinsic muscles stand out among the others because its origin and insertion are located within the belly of a muscle. They play a specific role on the part of the body where they are found. Action is a word used to describe the effect muscles have on movement in the body. Each group is connected to another leading to coordinated activity within the body.
Muscles are classified according to their functions and effect they have on body movement. Each category causes a particular effect to be felt because it works in a distinct way. The classes include agonist, synergist, antagonist and fixators.
Agonists are credited for producing huge forces in the body. This unique feature has earned them the name prime movers. They are responsible for basic body movement. Synergists work together with agonist to restrict, direct and coordinate their actions. One agonist requires a group of synergists to effectively function. They support directed motion.
Antagonists work in opposition to the force created by agonist. They achieve this through restriction of range or speed of movement. Such action creates an antagonistic pair where muscles are pulling in different directions. Such action and reaction leads to coordinated movement with specific direction and speed.
The last category is referred to as fixators because they are specific for bones movement. They ensures that bone movement is restricted to prevent straining or dislocations. These restrictions prevent use of excessive force that would damage other tissues of the body. The relationship between these muscles is mutual ensuring that the body achieves coordinated movement.
Muscle attachments vary depending on the part of the human body and the nature of movement required. Identifying the attachment helps a learner appreciate movement. A combination of different muscle types leads to successful movement and action on the body.
