Question 2

Male urethra

Answer 2

The length is 18-20 cm

4 parts:
Penile the longest
Membranous the narrowest and shortest 2cm and the fixed one
Bolbous 
Prostatic is the widest

Anterior urethra (Penile and bulber urethra):
examined by —> ascending urethrogram 

Posterior urethra (Membernous and prostatic):
examined by —> micturating or descending cystourethrogrm

Most common injured urethra in general is the membranous bec it is fixed by the urogenital diaphragm and the mechanism usually blunt trauma (saddle injury)

In the anterior urethra the commonest to be injured is the penile

The verumontanum or seminal colliculus is the rounded eminence of the urethral crest within the posterior wall of the mid prostatic urethra. The prostatic utricle opens into it in the midline and the two ejaculatory ducts open just distal to the utricle. On either side of it lie the prostatic sinuses, where numerous prostatic ducts drain.
