Muscles of the Body

muscles of the body

Muscles of the body have different names depending on their size, direction, and shape. We will learn their names as well as their functions in this article. The body’s major muscle groups include:

Shape

Muscles are classified according to their shape and size. The biceps muscle has a distinctive squished belly, while the orbicularis has a rhombus-shaped head. The gluteus maximus is the largest muscle in the body, and the orbicularis is the smallest. The names of muscles also indicate their length and relative position to the midline. This information is helpful in determining the size and shape of a muscle.

Size

Size is not the only determining factor in muscle development, as larger muscles produce more force than smaller ones. In addition, muscle size decreases relative strength. This fact is reflected in a study published in the November 2015 issue of Experimental Physiology. For more information, check out the article linked below. Here are some facts about muscle size and strength. To understand how muscle size affects strength, consider the three different types of muscles.

Direction

A description of the direction of muscles in the body is often not accurate. Although they all attach to bones, the names of individual muscles can lead to confusion. Rectus abdominis and oblique abdominis are both considered oblique, and both are located on the upper and lower sides of the body. In order to understand which muscle is which, we’ll first look at the names. Depending on the location, a name may indicate the type of movement.

Functions

The main function of the muscles of the body is to move the body and to support it. Muscles are tissues that contract to move the body, supporting bones and controlling voluntary movement. The cardiac muscle propels blood and helps it reach the other parts of the body, while smooth muscle, which spans the body, contracts to shorten and propel contents across the lumen of multiple organ systems. The muscular system is controlled by the nervous system.

Location

Muscles are named according to where they are located on the body. These muscles are also known as skeletal muscles. Their names reflect their position in relation to the midline. For instance, the frontalis muscle is located on the frontal bone of the skull. Likewise, the rectus abdominis muscle is located in the abdominal region. And the oblique abdominis muscle is located in the frontal bone.
