Axillary Recess

Fig. 6.137a-c. Intra-articular loose bodies, a Schematic drawing of a coronal view through the shoulder illustrates the dependent pouches of a communicating glenohumeral-bursal cavity where loose bodies are more commonly found. They are the lateral recess of the bursa (1), the biceps tendon sheath (2), the axillary recess (3) and the subcoracoid bursa (4). b,c Gross appearance of some small intra-articular loose bodies b at arthroscopic view and c photographed after arthroscopic removal... 

Atrichia with papular lesions (APL) is a rare autosomal-recessive form of total alopecia. Affected individuals are both without eyebrows and eyelashes, and never develop axillary and pubic hair. The scalp hair usually appears normal at birth, but falls out soon after. Defects in the human homolog of the mouse hairless gene (Hr) have been implicated as the molecular basis of this rare form of congenital hair loss.
