Question 4 - Name the parts of the urethra in males (4 marks)

The urethra in males is divided into four parts:

1. Pre-prostatic Urethra: This is the initial part of the urethra that is connected to the bladder. It is surrounded by the internal urethral sphincter which controls the flow of urine from the bladder.

2. Prostatic Urethra: This part of the urethra passes through the prostate gland. Seminal ducts from the prostate gland open into this part of the urethra.

3. Membranous Urethra: This is the shortest and narrowest part of the male urethra. It passes through the urogenital diaphragm and is surrounded by the external urethral sphincter.

4. Spongy or Penile Urethra: This is the longest part of the urethra that passes through the penis. The ducts from the bulbourethral glands open into this part of the urethra.
