ABSTRACT
Axillary arch muscles have been described as having variable and sometimes multiple insertions. We report a 90-year-old female cadaver with an axillary arch muscle that originated from the latissimus dorsi and was inserted into the pectoralis major, pectoralis minor and coracoid process. Recognising that axillary arch muscles can be present in such complex forms is important in clinical practice.

Keywords: axillary arch muscle of Langer, coracoid process, latissimus dorsi, pectoralis major muscle, pectoralis minor muscle
