Penis Shaft Anatomy
The penis shaft is composed of three main erectile structures: two corpora cavernosa and one corpus spongiosum. Surrounding these structures is a layer of connective tissue, skin, blood vessels, and nerves.
Corpora Cavernosa
These two chambers run along the top of the shaft and fill with blood during arousal, causing the penis to become firm.
Corpus Spongiosum
This structure surrounds the urethra and helps protect the urinary passage during erection.
Skin and Nerve Supply
The skin on the penile shaft is thin and sensitive. Nerves support pleasurable sensation and contribute to sexual response.
