The corpus cavernosum refers to two sponge-like regions of erectile tissue found in the penis. These structures fill with blood during sexual arousal, causing an erection. The urethra is a tube that carries urine from the bladder out of the body and also transports semen during ejaculation. Diseases affecting these areas can impact sexual function, urinary health, and overall well-being.
- Corpus Cavernosum: Erectile tissue in the penis responsible for achieving and maintaining an erection.
- Urethra: A tube that conducts urine from the bladder to the outside of the body and semen during ejaculation.
- Erectile Dysfunction (ED): The inability to achieve or maintain an erection suitable for sexual intercourse.
- Urethritis: Inflammation of the urethra, often caused by infection.
- Peyronie’s Disease: A condition where fibrous scar tissue develops inside the penis, causing curved, painful erections.
Pathophysiology
Structure
- Corpus Cavernosum: Each penis contains two corpora cavernosa running along its length. These tissues are composed of sponge-like columns of erectile tissue containing blood vessels and smooth muscle.
- Urethra: Extends from the bladder through the penis, surrounded by the corpus spongiosum (another erectile tissue) to keep the urethra open during erection.
Blood Supply
- The corpus cavernosum receives blood through the deep artery of the penis. During sexual arousal, these arteries dilate, increasing blood flow into the erectile tissue.
- Veins that drain blood from the corpus cavernosum are tightly compressed to maintain the erection by trapping blood within the tissue.
Nerve Supply
- Autonomic Nervous System: Controls blood flow into and out of the corpus cavernosum.
- Somatic Nerves: Responsible for sensation and erection.
- Proper nerve function is crucial for initiating and maintaining erections.
