Options:
explanation: This is a model of the male pelvic and reproductive anatomy. The suspensory ligament of the penis is a midline structure which is attached to the pubic symphysis and maintains the position of the penis during erection. The arrow indicates the spermatic cord, a collection of structures running from the lower abdominal wall into the scrotum. These structures include the ductus deferens of the testicle, the arterial supply, venous and lymphatic drainage of the ipsilateral testicle. The contents of the spermatic cord are covered by three fascial layers – the external spermatic fascia, the cremaster fascia and the internal spermatic fascia.
name: Suspensory ligament of the penis
label: e
answer: no
explanation: This is a model of the male pelvic and reproductive anatomy. The inguinal ligament (and the lacunar ligament medially), form the floor of the inguinal canal. The inguinal ligament runs from the anterior superior iliac spine to the pubic tubercle. The spermatic cord is formed at the opening of the inguinal canal (or the deep inguinal ring), passes through the inguinal canal and enters the scrotum via the superficial inguinal ring. Here the spermatic cord can be seen leaving the inguinal canal.
name: Inguinal ligament
label: b
answer: no
explanation: This is a model of the male pelvic and reproductive anatomy. The external iliac artery is a branch of the common iliac artery. The external iliac artery then passes beneath the inguinal ligament to become the femoral artery. The external iliac artery is not shown in this model. The arrow indicates the spermatic cord, a collection of structures running from the lower abdominal wall into the scrotum. These structures include the ductus deferens of the testicle, the arterial supply, venous and lymphatic drainage of the ipsilateral testicle. The contents of the spermatic cord are covered by three fascial layers – the external spermatic fascia, the cremaster fascia and the internal spermatic fascia.
name: External iliac artery
label: d
answer: no
explanation: This is a model of the male pelvic and reproductive anatomy. The arrow indicates the spermatic cord, a collection of structures running from the lower abdominal wall into the scrotum. These structures include the ductus deferens of the testicle, the arterial supply, venous and lymphatic drainage of the ipsilateral testicle. The contents of the spermatic cord are covered by three fascial layers – the external spermatic fascia, the cremaster fascia and the internal spermatic fascia.
name: Spermatic cord
label: a
answer: yes
explanation: This is a model of the male pelvic and reproductive anatomy. The femoral nerve, artery and vein are located inferior to the inguinal canal, and lateral to the spermatic cord. They are not depicted in this model. The external iliac artery passes beneath the inguinal ligament to become the femoral artery and supplies the lower limb. The arrow indicates the spermatic cord, a collection of structures running from the lower abdominal wall into the scrotum. These structures include the ductus deferens of the testicle, the arterial supply, venous and lymphatic drainage of the ipsilateral testicle. The contents of the spermatic cord are covered by three fascial layers – the external spermatic fascia, the cremaster fascia and the internal spermatic fascia.
name: Femoral artery
label: c
answer: no

Correct answer: a
