For that reason, and because of the dexterity of the shoulder joint itself, the musculature of the shoulder is complex, ranging from massive prime mover muscles to finer stabilizer and fixator muscles. The shoulder (or humeroscapular) joint is formed by the articulation of the head of the humerus with 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.

Types of muscle cells
Skeletal Muscle cells. Skeletal muscle cells are long, cylindrical, and striated.
Cardiac Muscle Cells. Cardiomyocytes are short and narrow, and fairly rectangular in shape.
Smooth Muscle Cells. Smooth muscle cells are spindle-shaped and contain a single central nucleus.

The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

Rectus abdominis. The human rectus abdominis muscle. [edit on Wikidata] Example of a man with a visible rectus abdominis. The rectus abdominis muscle, also known as the “abdominal muscle” or “abs”, is a paired muscle running vertically on each side of the anterior wall of the human abdomen, as well as that of some other mammals.

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.

Muscle diagrams are a great way to get an overview of all of the muscles within a body region. Studying these is an ideal first step before moving onto the more advanced practices of muscle labeling and quizzes. If you’re looking for a speedy way to learn muscle anatomy, look no further than our anatomy crash courses .

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.

Shoulder Tendons. Tendons are extensions of muscles that attach muscles to bone. Muscles move the bones by pulling on the tendons.

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.

The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

Upper arm muscle pain is characterized by mild to severe pain in the muscles between the shoulder and the elbow. It may last for a short time or even become a chronic problem. The arms are the most used body parts and they can be subjected to much pressure and strain.

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.

Muscles of neck. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing. The motion of the muscles of the neck are divided into four categories: rotation, lateral flexion, flexion, and hyperextension. Rotation describes the action of moving the head from side to side,…

These muscles and the deep muscles of the neck can be the causes of neck pain due to muscle strains, muscle tension, and other issues. A common cause of neck pain is muscle strain. This is often a result of incorrect posture.

Superficial Muscles. Located underneath the platysma on the sides of the neck are the sternocleidomastoid muscles. With one on each side of the neck, these help flex the neck and rotate the head upward and side to side. They stretch from behind the ear diagonally to the center of the chest at the sternum.

Cardiac Muscle Cells. Cardiomyocytes are short and narrow, and fairly rectangular in shape.
Smooth Muscle Cells. Smooth muscle cells are spindle-shaped and contain a single central nucleus.

Muscle Cell Definition: A muscle cell is also known as Myocyte, which is a specialized animal cell that can shorten its length by using a series of motor proteins especially arranged in the cell.

The short, non-striated — and, hence — smooth muscle cells contain only one nucleus. Cardiac muscle cells appear striated, though they also appear less organized into stripes than skeletal muscle cells. These cells may branch out, forming physical connections with many surrounding cells.

Upper Back Muscles. The deltoid, teres major, teres minor, infraspinatus, supraspinatus (not shown) and subscapularis muscles (not shown) all extend from the scapula to the humerus and act on the shoulder joint. The trapezius and latissimus dorsi muscles connect the upper limb to the vertebral column.

Upper Back Muscles. The deltoid, teres major, teres minor, infraspinatus, supraspinatus (not shown) and subscapularis muscles (not shown) all extend from the scapula to the humerus and act on the shoulder joint.

The back anatomy includes the latissimus dorsi, trapezius, erector spinae, rhomboid, and the teres major. On this page, you’ll learn about each of these muscles, their locations and functional anatomy. Function of the Back Muscles There are several individual muscles within the back anatomy, and it’s important to take a quick look at all of

Function of the Back Muscles. The back muscles enable you to stand up straight; support and protect your spine; and reach, pull and extend your arms and torso. Poorly developed back muscles lead to everything from muscle tweaks and pulls to imbalances of the musculature to the all-too-common hunched-over look (the “Neanderthal look”).

Back muscles are divided into two specific groups: the extrinsic muscles that are associated with upper extremity and shoulder movement, and the intrinsic muscles that deal with movements of the vertebral column. Several small muscles in the cervical area of the vertebral column are also important.

There are three types of muscles: Skeletal muscles are attached mainly to the skeletal bones but some are also attached to other structures (such as the eyes for eye movement) and causes movements of the body. Cardiac muscle is responsible for the rhythmic contractions of the heart. Smooth muscle lines the walls of hollow organs.

The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

The deltoid muscles are shoulder muscles of the human body. These muscles are broken into three groups, which are the anterior, lateral, and posterior muscles. The anterior deltoid is the muscle located on the front area of the shoulder. This muscle is primarily used by the body to lift the arms straight overhead.

Located superior to the shoulder joint, the deltoid muscle works with the supraspinatus to abduct the arm at the shoulder. On the anterior side of the shoulder, the coracobrachialis, serratus anterior, pectoralis major, and pectoralis minor muscles work as a group to flex and adduct the scapula and humerus anteriorly toward the sternum.

It is named after the Greek letter delta, which is shaped like an equilateral triangle. The deltoid is attached by tendons to the skeleton at the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone).
