Identify the three regions of the male urethra.

Guida verificata passo dopo passo

Understand that the male urethra is divided into three main anatomical regions based on their location and surrounding structures.

Identify the first region as the prostatic urethra, which passes through the prostate gland and is the widest part of the urethra.

Recognize the second region as the membranous urethra, which is the shortest and narrowest part, passing through the urogenital diaphragm.

Identify the third region as the spongy (or penile) urethra, which runs through the length of the penis within the corpus spongiosum and ends at the external urethral orifice.

Summarize the three regions as: prostatic urethra, membranous urethra, and spongy (penile) urethra.
