Proximal phalanges III-V – muscles cross the metatarsophalangeal joint of the toes III-V, so that the insertions match the origin and there is no crossing between the toes

Minus the term “muscle”, with words occasionally rearranged for better classification. The loins and abs are listed as separate lines, as they are sometimes considered separate muscles. – Everything that touches the relationship of a muscle to another muscle, such as superior, inferior, etc. should always be used as a suffix rather than a prefix to create a better sorting list.

Location of the muscle in the standard human body. The location first defines a group such as head, neck, trunk, upper limbs or lower limbs, it can have more specific information. However, this additional information should describe the location and not the features.

A bone or other structure to which a muscle is attached and remains stationary during action. The term “bone” is omitted from bone names.

The nerve(s) that tells the muscle to work (innervates the muscle). The term “nerve” is included for clarity.

Movement performed by a muscle from a standard anatomical position. Other actions may be performed in other positions.

A muscle that can “cancel” or reverse the action of a muscle to some extent. Muscle synergies are seen in the particles that matter.

How many times does the named muscle type occur in a standard human body. It may also be pointed out here that giv muscles occur only in the male or female body. With (F) for female and (M) for male if nothing is marked. We can assume that the muscle occurs in both kjerrs. This where dominance should always be behind the number, not in front of it.

The number of rows in the table for the corresponding Terminologia Anatomica muscle. For example, TA divides the nasal muscle into transverse and alar parts, so their columns are TA of experiment 2.

Name specific ribs, thoracic vertebrae, or cervical vertebrae using C1-7, T1-12, or R1-12 for origin, insertion, and function.

There seems to be no definitive source that counts all skeletal muscles. Different sources group muscles differently depending on what is defined as different parts of a single muscle or as multiple muscles. There are also vestigial muscles that are present in some people and absent in others, such as the palmaris longus muscle.

The typical human body contains between 600 and 840 muscles, depending on how you count them.

In the first table, using a statistical count of the instances of each muscle and not considering where-specific muscles, there are 761 skeletal muscles. Sometimes males and females have the same muscle, but with a different purpose

Specified muscles that do not occur in a standard human 2023 (where specific muscles that occur in a standard male or female are not counted here)

This can be a bit misleading because generally groups of muscles work together to make or break a movement.

Human muscular system, the muscles of the human body that act on the skeletal system, are under voluntary control and are related to movement, posture, and balance. In general, human muscle—like that of all vertebrates—is often divided into striated muscle (or skeletal muscle), smooth muscle, and cardiac muscle. Smooth muscle is under involuntary control and is found in the walls of blood vessels and structures such as the bladder, intestines, and stomach. Cardiac muscle forms the mass of the heart and is responsible for the rhythmic contractions of this vital pumping organ; this too is under involuntary control. With very few exceptions, the distribution of smooth muscle and cardiac muscle in humans is the same as that of other vertebrates.

This article deals with the skeletal muscles of the human body, focusing on muscle movements and the changes that occurred in human skeletal musculature as a result of a long evolutionary process that involved the adoption of an upright posture. Smooth muscle and cardiac muscle and the physiology of muscle contraction are discussed extensively in the muscle article. For descriptions of disorders affecting the human muscular system,

The following sections provide a basic framework for understanding gross human muscle anatomy with descriptions of major muscle groups and their function. Different muscle groups work in harmony and control the movement of the human body.

Neck movement is described by rotation, flexion, extension, and lateral flexion (ie, the movement used to touch the ear with the shoulder). The direction of action can be ipsilateral, which refers to movement in the direction of the muscle that is contracting, or contralateral, which refers to movement away from the side of the muscle that is contracting.

Rotation is one of the most important actions of the cervical (cervical) spine. Rotation is primarily performed by the sternocleidomastoid muscle, which flexes the neck to the ipsilateral side and rotates the neck contralaterally. Together, the sternocleidomastoid muscles on both sides of the neck flex the neck and lift the sternum, helping with forced inspiration. The scalene anterior and middle muscles, also located on the sides of the neck, work ipsilaterally to rotate the neck and to elevate the first rib. Splenius capitis and splenius cervicis, located at the back of the neck, work to rotate the head.

Lateral bending is also an important action of the cervical spine. The sternocleidomastoid muscles are involved in bending the side of the neck. The posterior scalene muscles, located on the lower sides of the neck, ipsilaterally bend the neck laterally and lift the other rib. The splenius capitis and splenius cervicis also help in lateral bending of the neck. The erector spinae muscles (iliocostalis, longissimus, and spinalis) are large, deep muscles that run the length of the back. All three work to flex the neck on the same side.

Bending the neck refers to the movement in which the chin touches the chest. It is mainly performed by the sternocleidomastoid muscles with the help of longus colli and longus capitis, which are located on the front of the neck. Neck extension is the opposite of flexion and is performed by many of the same muscles used for other neck movements, including the splenius cervicis, splenius capitis, iliocostalis, longissimus, and spinalis muscles.

There are many muscles on the back that are involved in the movement of the neck and shoulders. In addition, the axial skeleton, which runs vertically through the back, protects the spinal cord, which innervates almost every muscle in the body.

Several back muscles work specifically to move the back. For example, the erector spinae muscles extend the back (bend it back) and laterally bend the back.
