The deltoid muscle is the muscle [1] forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis)
The deltoid is a large, triangular shaped muscle that covers the top of each shoulder joint. The deltoids are comprised of three parts: The anterior (front) deltoid: Helps with shoulder flexion ...
The axillary nerve supplies two muscles in the arm: deltoid (a muscle of the shoulder) and teres minor (one of the rotator cuff muscles). The axillary nerve also carries sensory information from the shoulder joint. It also innervates the skin, covering the inferior region of the deltoid muscle, known as the regimental badge area. [9]
In addition to the four muscles of the rotator cuff, the deltoid muscle and teres major muscles arise and exist in the shoulder region itself. [3] The deltoid muscle covers the shoulder joint on three sides, arising from the front upper third of the clavicle, the acromion, and the spine of the scapula, and travelling to insert on the deltoid ...
In human anatomy, the deltoid tuberosity is a rough, triangular [1] area on the antero lateral (front-side) surface of the middle of the humerus. [2] It is a site of attachment of deltoid muscle . [ 2 ]
The deltoid tubercle of spine of scapula is a prominence on the spine of scapula. The spine, at lateral to the root of the spine , curves down and laterally to form a lip. [ 1 ] This lip is called the deltoid tubercle.
The shoulder fly (also known as a lateral raise) works the deltoid muscle of the shoulder. The movement starts with the arms straight, and the hands holding weights at the sides or in front of the body. Body is in a slight forward-leaning position with hips and knees bent a little.
A variety of methods may be used to diagnose axillary nerve palsy. The health practitioner may examine the shoulder for muscle atrophy of the deltoid muscle. [2] Furthermore, a patient can also be tested for weakness when asked to raise the arm. [2] The deltoid extension lag sign test is one way to evaluate the severity of the muscle weakness.
