چکیده
Langer's arch is one of the rare muscular variation in the axillary region. In the present article, a case of 50 year old male cadaver with axillary arch in the right axillary region is being reported. It originated from anterior border of latissimus dorsi and merged with short head of biceps brachii. The embryological derivation, genetic basis and clinical implication of this muscular variant are also discussed.

Innervations of Muscular Axillary Arch of Latissimus Dorsi by Pectoral Loop
Latissimus Dorsi is a Hat and triangular muscle that covers the lumbar region and the inferior part of the thorax.The innervation of this muscle is from the thoracodorsal nerve (C6, C7, CS), a branch of posterior cord of the brachial plexus. This report deals with the dissection of the axillary region of a male cadaver. In this cadaver, we observed a muscular axillary arch which was innervated ...
متن کاملAn unusual case of axillary arch bridging across the anterior and posterior axillary folds in the distal part of axilla
Introduction Axillary arch is an additional muscle bundle of various dimensions extending from latissimus dorsi in the posterior fold of the axilla, to the pectoralis major in the anterior fold, to the short head of the biceps brachii or to the coracoid process [1, 2]. Ramsay, in 1795, described the axillary arch for the first time. He gave the description of a muscle bundle connecting pectoral...

Introduction A number of accessory muscle slip cases in the axilla arising from latissimus dorsi, pectoralis major, ribs and costal cartilages have been reported by different authors [1]. These accessory muscle slips in the axilla have been described under variety of names (e.g., chondro-epitrochlearis, dorsoepitrochlearis, etc). These variant bundles are commonly referred to as “axillary arch”...
متن کاملLanger’s axillary arch (axillopectoral muscle): a variation of latissimus dorsi muscle
Best-known variant structure of the axillary components of men is a muscular or fibro-muscular slip extending from the latissimus dorsi muscle to the tendons, muscles or fasciae of the superior part of the humerus. This variation had first described by Ramsay in 1795 and confirmed by Langer in 1864 and named as axillary arch of Langer. Although different frequencies have been reported from cada...
متن کاملClinical importance of the muscular arch of the axilla (axillopectoral muscle, Langer's axillary arch).
The muscular arch of the axilla is described in a male cadaver on the left side. The condition may be the result of a factor affecting the intrauterin development. Because this muscular arch causes difficulties in staging lymph nodes, axillary surgery, thoracic outlet syndrome, shoulder instability or cosmetic problems, it should be kept in mind for axillary pathologies.
