An Axillary Arch Muscle And Its Clinical Importance- A Case Report
Journal Title: International Journal of Medical and Health Sciences - Year 2013, Vol 2, Issue 2
Abstract
The axilla is a pyramidal space, situated between the upper lateral part of the chest and the medial side of the arm. Axilla is the area connects the cervical and upper limb regions; most of the important structures from neck region passes through the axilla and reach the upper limb. Knowledge of muscular, vascular, and neural variations in the axilla is of great clinical importance, especially in mastectomies, breast reconstruction, and axillary bypass operations. During routine dissections for undergraduate medical students at Department of Anatomy, in an 84-year-old male cadaver, we found a muscular slip on the right axillary fossa that originated from latissimus dorsi muscle and attached to the deep surface of the tendon of pectoralis major muscle.The axillary artery proximal to the arch muscle showed variable course. The compression of neurovascular bundle of axilla by an axillary arch muscle is discussed in literature. Presence of an axillary arch muscle has immense clinical and morphological significance.
