Where is the Location of the One-Head Muscle?

In medicine, there is no term called "one-head muscle". Instead, we usually refer to biceps brachii and triceps brachii. There is also no specific location for the "one-head muscle". If we insist on naming it, we can consider the lower half of the biceps brachii, which is the deep muscle within, as the "one-head muscle".

In medicine, there is no term for the "one-head muscle". We only have biceps brachii and triceps brachii. The biceps brachii is located on the front side of the arm. Its overall shape is fusiform because it has both long and short muscle fibers, hence the name "biceps brachii". Technically speaking, there is no existence of the "one-head muscle". If we insist on naming it, we can consider the lower half of the biceps brachii, which is the deep muscle within, as the "one-head muscle".

The human body has 206 bones and 639 muscles. Here, the muscles refer to skeletal muscles, which connect various bones, tendons, and membranes throughout the body. Their contraction and relaxation enable our joints, eyeballs, eyelids, mouth, and other parts to move. They also allow us to breathe. These skeletal muscles are composed of many muscle cells adhered together to form bundles, hence the total count of 639 muscles. However, due to genetic differences, some people may have "extra" muscles while others may have "fewer" muscles. The extra muscles are usually those that have atrophied, been abandoned, or evolved to disappear in ordinary people. The missing muscles can be explained as having evolved. These variations in muscle mass do not affect our daily activities. Additionally, we also have smooth muscles and cardiac muscles in our bodies. These cells do not exist in bundles, so it is impossible to accurately count their exact number, and everyone has a different quantity of smooth muscle and cardiac muscle cells.
