The two crura of penis (one crus on each side) constitute the root of penis along with the bulb of penis. The two crura flank the bulb – one to each side of the bulb. Each crus is attached at the angle between the perineal membrane and ischiopubic ramus. The deep artery of the penis enters the anterior portion of the crus. Distally, each crus transitions into either corpus spongiosum of the body of the penis.[1]
Structure
[edit]Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end.[citation needed]
Each crus begins proximally as a blunt-pointed process in anterior to the tuberosity of the ischium, along the perineal surface of the conjoined (ischiopubic) ramus.[citation needed]
Just proximal to the convergence of the two crura, they come into contact with the bulb of (corpus cavernosum of) penis.[citation needed]
The crura are covered by an ischiocavernosus muscle.
