Fibers Arc-shaped External

External arcuate fibers (f. arcuate externae) are a group of muscle fibers that are located in the outer part of the muscle. They have an arcuate shape and are located along the muscle, forming its outer surface.

External arcuate fibers play an important role in muscle function. They are responsible for maintaining the shape and tone of the muscle, as well as its ability to contract. In addition, these fibers are involved in the transmission of nerve impulses from the central nervous system to the muscles.

External arcuate fibers may also be involved in various diseases such as myopathy, arthritis and others. In such cases, muscle and fiber function is disrupted, which can lead to a variety of symptoms including weakness, pain and loss of function.

In this article we will consider the topic of arcuate external fibers.

Arc-shaped internal fibers are important elements of human skin. These fibers are made up of proteins and their functions include maintaining skin elasticity, protecting against external influences, and ensuring uniform pigment formation in the skin. The fibers of the inner surface are equipped with dendrites of Merkel cells and nerve endings, which allows them to perceive pain and tactile sensations. The skin would not be as smooth if this small group of fibers were not present on our skin. And now we will look at the outer layer of our skin - HAIR.

The outer layer of the skin, the epidermis, is formed by a multilayer shield of epidermal cells tightly adjacent to each other - scales, hairs, glands. Since hair is part of the epidermis, these cells are named accordingly. The largest part of the skin from a biological point of view - the dermis - has a structure
