Gross Features

The glans is the most distal cone-shaped portion of the penis and is covered by a soft rubbery mucosal membrane devoid of adnexal structures extending through the coronal sulcus and inner foreskin. It contains the glans corona, frenulum, and meatus urethralis. The corona corresponds to the most proximal and widest portion of the glans. The frenulum is an infolding of the inner foreskin inserted at the level of the meatus urethralis. The meatus urethralis is a ventrally located slit-like orifice near the tip of the glans which receives the distal (penile) urethra. From a cut surface through the glans the following anatomical levels are discernable from surface to deep tissues: (1) a squamous mucosa; (2) corpus spongiosum, forming most of the glans volume; and (3) corpus cavernosum, surrounded by the tunica albuginea. The foreskin is a mucocutaneous infolding which covers the glans and presents an inner

Fig. 3.1 Anatomy of penis mucosal surface that reflects over itself to continue in the outer surface as the preputial skin. The zone of reflection forms the preputial orifice. At cut surface the foreskin presents the following anatomical levels from surface to deep tissues:

1. A squamous mucosa

2. Bundles of the dartos muscle extending from the homologous layer in the shaft

3. Preputial skin

The coronal sulcus is a cul-de-sac located between the glans corona and the inner foreskin. From surface to deep tissues the following anatomical layers are recognized:

1. A squamous mucosa

2. Bundles of dartos muscle, reflecting from fibers passing from the shaft to the foreskin

3. Buck's fascia

The penile shaft is covered by skin, similar to that found elsewhere. A transverse section through the middle of the shaft will disclose the following anatomical levels

1. Skin of the shaft

2. Bundles of dartos muscle

3. Buck's fascia

4. Two dorsally located corpora cavernosa enclosed in a tunica albuginea and separated by a median septum

5. A ventrally located corpus spongiosum with the penile urethra.

The penile urethra enters the corpus spongiosum in the penile root and runs throughout its entire length. Proximal to the meatus urethralis it expands to form the fossa navicularis. Surrounding the penile urethra there is a connective tissue merging imperceptibly to the corpus spongiosum.
