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 anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment. The compartment contains three muscles; the biceps brachii, the brachialis and the ...
The muscles of internal rotation include: of arm/humerus at shoulder. Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3 ...
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
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 ...
The size and orientation of its functionally important features, including the deltoid tubercle, greater tubercle, and medial epicondyle, are pivotal to an animal's style of locomotion and habitat. In cursorial (running) animals such as the pronghorn , the deltoid tubercle is located about a quarter of the way down the shaft, which allows for ...
The coracoid process of the scapula is not subcutaneous; It is covered by the anterior border of the deltoid. However, the tip of the coracoid process can be felt on deep palpation on the lateral aspect of the clavipectoral triangle. The coracoid process is used as a bony landmark when performing a brachial plexus block.
