This is a table of skeletal muscles of the human anatomy. There are around 640 skeletal muscles within the typical human body.

Cardiac and skeletal muscles are “striated” in that they contain sarcomeres and are packed into highly regular arrangements of bundles; smooth muscle has neither.

The torso also harbours many of the main groups of muscles in the body, including the: The organs, muscles, and other contents of the torso are supplied by nerves, which mainly originate as nerve roots from the thoracic and lumbar parts of the spinal cord. Some organs also receive a nerve supply from the vagus nerve.

Muscle Cell Definition. A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell.

This structure is similar to the smooth endoplasmic reticulum of other types of cell. To produce contractile force, myosin associates with actin filaments, rotating a little and then pulling the filaments across each other, like oars propelling a boat. Skeletal muscle cells also contain two regulatory proteins, known as troponin and tropomyosin.

Skeletal muscle is a fascinating tissue with a complex structure. It consists of elongated multinuclear cells called the myocytes (or myofibers). The muscle cells can be anything from 1 mm to 30 cm in length. The longest muscle cell in our bodies can be found in the sartorius muscle and is 30 cm (nearly 12 inches!) long.

There are around 640 skeletal muscles within the typical human body. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article.

Chest Anatomy: All About the Chest Muscles. The chest anatomy includes the pectoralis major, pectoralis minor and the serratus anterior. Learn about each of these muscles, their locations, functional anatomy and exercises for them.

Function of the Chest Muscles. The chest is part of a larger group of “pushing muscles” found in the upper body. The chest, as part of this group, enables you to perform pushing actions such as the barbell bench press or a daily activity such as moving a heavy dresser.

Shoulder Muscles Anatomy. Shoulder muscles move the shoulder blades and upper arm bones. The main shoulder muscles are trapezius, deltoid, pectoralis major and 4 rotator cuff muscles: subscapularis, supraspinatus, infraspinatus and teres minor.

Each joint is surrounded by: tendons, to attach the muscles to the bones. The collection of muscles and tendons in the shoulder is known as the rotator cuff. It stabilizes the shoulder and holds the head of the humerus in the glenoid, a shallow cavity in the scapula.

Medically reviewed by Healthline’s Medical Network on March 23, 2015. The shoulder has about eight muscles that attach to the scapula, humerus, and clavicle. These muscles form the outer shape of the shoulder and underarm.

The muscles in the shoulder aid in a wide range of movement and help protect and maintain the main shoulder joint, known as the glenohumeral joint. The largest of these shoulder muscles is the deltoid. This large triangular muscle covers the glenohumeral joint and gives the shoulder its rounded-off shape.

Some compound exercises for the legs also involve the lower back. Bodybuilders commonly divide the body’s individual muscles into ten major muscle groups. These do not include the hip, neck and forearm muscles, which are rarely trained in isolation. The most common exercises for these muscle groups are listed above.

The upper body comprises seven general muscle regions in the shoulders, chest and back. Each of these regions contains several muscle groups consisting of several muscle heads, or parts.

The main muscle group of the chest is the pectorals. A well-developed chest is very important because it will add major size to your inner upper body. The chest is a very visible part of the upper body, that can add weight and force to all your martial arts moves. The pectorals or pecs are the large chest muscles.

Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body.

[edit on Wikidata] Skeletal muscle is one of three major muscle types, the others being cardiac muscle and smooth muscle. It is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.

Rectus abdominis. The rectus abdominis muscle is located in the front of the body, beginning at the pubic bone and ending at the sternum. It is located inside the abdominal region. The muscle is activated while doing crunches because it pulls the ribs and the pelvis in and curves the back.

The rectus abdominis is an important postural muscle. It is responsible for flexing the lumbar spine, as when doing a so-called “crunch” sit up.

The number of muscles of the body is estimated to be around 600, so there’s certainly a lot to cover. A good way to get started is to learn using a regional approach. For example, starting by learning the muscles of the upper extremity, then the muscles of the lower extremity, and so on.

Picture of the Stomach. The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

These are located in the shoulder blade area, and each related tendon also attaches to the humerus. The supraspinatus muscle and tendon allow the arm to raise and lower. The infraspinatus muscle and tendon allow the arm to extend forward and sideways. The teres minor and subscapularis muscles and tendons allow the arm to rotate.

There are 10 muscles and 11 shoulder tendons related to shoulder mobility. The shoulder joint offers a fuller range of motion than any other joint in the body. The bicep has two shoulder tendons: the long head and the short head.

See your doctor for a precise diagnosis if you have upper arm muscle pain. According to medical specialists, pain in the upper arm is normally located in between the shoulder and the elbow.

In this article, we shall look at the anatomy of the muscles of the upper arm – their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm – biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve.
