The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. value these charts show the major superficial and deep muscles of the human body. Design › Anatomy and Physiology › Muscle Charts of the Human Body. List of skeletal muscles of the human body. This is a table of skeletal muscles of the human anatomy. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately pairs of muscles, as presented in this article.‎Head · ‎Torso · ‎Upper limbs · ‎Lower limb.

Muscles of the back.

The erector spinae muscles, for example, extend the back bend it backward and side bend the back. The semispinalis dorsi and semispinalis capitis muscles also extend the back.

Muscular System

The small muscles of the vertebrae the multifidi and rotators help rotate, extend, and side human muscle anatomy the back. The quadratus lumborum muscle in the lower back side bends the lumbar spine and aids in the inspiration of air through its stabilizing affects at its insertion at the 12th rib the last of the floating ribs.

The scapula shoulder blade is elevated by the trapezius musclewhich runs from the back of the neck to the middle of the back, by the rhomboid major and rhomboid minor muscles in the upper back, and by the levator scapulae muscle, which runs along the side and back of the neck.

The shoulder The shoulder is a complex ball-and-socket joint comprising the head of the humerusthe clavicle collarboneand the scapula. Muscles of the shoulder.

Shoulder flexion is movement of the shoulder in a human muscle anatomy motion. An example of shoulder flexion can be seen when reaching forward to grasp an object.

That action is accomplished primarily by the combined actions of the deltoid muscle in the uppermost extent of the arm, the pectoralis major muscle in the chest, the coracobrachialis muscle on the inside of the upper arm, and the biceps brachii muscles on the front of the upper arm.

Extension of the shoulder is opposite to human muscle anatomy. Pure shoulder extension is the movement of the arm directly behind the body, as in receiving a baton in a relay race. That movement is accomplished by the actions of the deltoid muscle, the latissimus dorsi muscle in the back, the teres major muscle in the armpit area, and the triceps muscle in the back of the upper arm.

The triceps, as the name suggests, consists of three heads that originate from different surfaces but share the same insertion at the olecranon process of the ulna a bone in the forearm ; the three heads together act to extend the elbow. Shoulder adduction and abduction serve to lower the arm toward and lift the arm away from the body, respectively.

They can be human muscle anatomy by picturing someone doing jumping jacks. Adduction is accomplished primarily by the pectoralis major, latissimus dorsi, teres major, triceps, and coracobrachialis. The deltoid and the supraspinatus, a muscle that runs along the scapula in the back, are the two main abductors of the shoulder.

An example of external rotation of the shoulder is seen in a tennis backhand human muscle anatomy. External rotation is attributed primarily to the deltoid, the teres minor in human muscle anatomy armpit area, and the infraspinatus muscle, which covers the scapula.

Internal rotation of the shoulder is the opposite of external rotation. An example is the shoulder movement that occurs when reaching into a back pocket. That movement is achieved through the coordinated action of the pectoralis major, latissimus dorsi, deltoid, teres major, and subscapularis muscles.

The subscapularis is a deep muscle situated on the anterior, or front-facing, surface of the scapula. The teres minor, subscapularis, supraspinatus, and infraspinatus muscles together form the rotator cuff, human muscle anatomy stabilizes the humeral head the ball portion of the ball-and-socket shoulder joint.

The muscles of human muscle anatomy rotator cuff are common sites of injury in adults, particularly among people who perform overhead motions repeatedly e.

Several of the rotator cuff muscles have tendons that run under the acromion, a bony prominence at the distal end of the scapula.

The term distal describes a relative position away from the centre of the body; it often is contrasted with the term proximal, which describes a relative position near to the centre of the body. The position of the tendons and of the subacromial human muscle anatomy fluid-filled sacs located beneath the acromion leaves them vulnerable to compression and pinching, which can result in an injury known as shoulder impingement syndrome.

The arm In addition to aiding the movement of the shoulder, the muscles of the upper arm produce various movements of the forearm. For example, the primary muscles involved in forearm flexion, in which the angle formed at the elbow becomes smaller i.
