Title: Penis
Description:
(A) Scheme. (B) Stain Azan, human. (C, D) Stain hematoxylin-eosin, human.
The penis consists of two corpora cavernosa (8) and a corpus spongiosum (10), which surround the urethra-seminal duct (11),
all ending up in the glans penis. All the corpora are encompassed with a dense connective tissue sheath, the tunica albuginea (7),
stained intensely blue in (B). A septum (9) divides the two corpora cavernosa. (6) The skin surrounds the tunica albuginea,
showing a multilayered, keratinizing squamous epithelium (4), followed by the cutis (5) and muscle cell fibers in the subcutis (6).
Details of the thin skin structure of the penis are shown in (C, D), with muscle fibers (12) and a hair follicle (13).
The corpora cavernosa in fact consist of labyrinth-like spaces or cisterns lined with endothelium and formed by trabeculae of
connective tissue and muscle fibers. These blood spaces are filled and drained by muscular helicine arteries (arteriae helicinae).
Keywords/Mesh: penis, cavernous body, corpus cavernosum, urethra, helicine artery, histology, POJA collection
