Deltoid Muscle 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). The deltoid is widest at the top of the shoulder and narrows to its apex as it travels down the arm. Contraction of the deltoid muscle results in a wide range of movement of the arm at the shoulder due to its location and the wide separation of its muscle fibers.... Click to read more below. The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder.

-    Antagonistic pairs are needed in the body because muscles can only  exert a pulling force, and can't push themselves back into their  original positions. An example of this kind of muscle pairing is  the biceps brachii and triceps brachii.n example of an Antagonistic pair is the contracting of the biceps while the triceps relax. The reverse occurs if the triceps were to contract. Moreover, this is known as the … elbow flexion that consists of the Biceps brachii and Triceps brachii.

Pointer Plus The Scalene muscle group is made up of the Scalenus anterior, Scalenus medius, Scalenus posterior, and Scalenus minimus.Scalenus Anterior The Scalenus anterior is a lateral muscle of the neck. Anatomical Attachments: Origin: Attaches to the anterior tubercles of the transverse processes of C3 through C6 vertebra.calenus Minimus The Scalenus minimus is an anterior muscle of the neck. Anatomical Attachments: According to Travell and Simons, this muscle is absent in a large percentage of the population. It lies posterior to the subclavian artery, underneath the inferior aspect of the Scalenus anterior.

Scalene muscles The middle scalene, (or scalenus medius), is the largest and longest of the three scalene muscles. The middle scalene arises from the posterior tubercles of the transverse processes of the lower six cervical vertebrae.he action of the anterior and middle scalene muscles is to elevate the first rib and laterally flex (bend) the neck to the same side; the action of the posterior scalene is to elevate the second rib and tilt the neck to the same side.

Deltoid Deltoid. The deltoid muscle is located on the outer aspect of the shoulder and is recognized by its triangular shape. The deltoid muscle was named after the Greek letter Delta due to the similar shape they both share. The deltoid muscle is constructed with three main sets of fibers: anterior, middle, and posterior.These fibers are connected by a very thick tendon and are anchored into a V-shaped channel.

Deltoid muscle In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography suggests that it consists of at least seven groups that can be independently coordinated by the nervous system.

- However, your feedback is important to us. The iliacus muscle is found in the lower portion of the trunk, covered in a thick fascia (connective tissue). This muscle is shaped like a triangle, flat, and an exact fit of the iliac fossa — the curved surface of the largest pelvic bone. Together with the psoas major muscle, it is also called the iliopsoas muscle.

Biceps brachii The biceps brachii, sometimes known simply as the biceps, is a skeletal muscle that is involved in the movement of the elbow and shoulder. It is a double-headed muscle, meaning that it has two points of origin or heads in the shoulder area. The short head of each biceps brachii originates at the top of the scapula (at the coracoid process). The long head originates just above the shoulder joint (at the supraglenoid tubercle).
