Options:
explanation: This image shows a dissection of the anterior surface of the lower abdomen and the superior aspect of the right lower limb. The right side of the image shows the male genitalia. The spermatic cord can be seen exiting the inguinal canal just inferior and medial to the arrow. The arrow points to the right inguinal canal. This is a short passage found in the lower abdominal wall, superior to the inguinal ligament, which allows the passage of various structures from the abdominal wall to the external genitalia.
name: Spermatic cord
label: d
answer: no
explanation: This image shows a dissection of the anterior surface of the lower abdomen and the superior aspect of the right lower limb. The right side of the image shows the male genitalia. The external iliac artery passes beneath the inguinal ligament to become the femoral artery, and supplies the lower limb. The femoral nerve, artery and vein (from lateral to medial) can be seen inferior to the inguinal canal. Thus, the arrow points to the right inguinal canal. This is a short passage found in the lower abdominal wall, superior to the inguinal ligament, which allows the passage of various structures from the abdominal wall to the external genitalia. For example, this is the passage by which the spermatic cord reaches the testicles in the scrotum. (The spermatic cord can be seen exiting the inguinal canal just inferior and medial to the arrow).
name: Femoral artery
label: c
answer: no
explanation: This image shows a dissection of the anterior surface of the lower abdomen and the superior aspect of the right lower limb. The right side of the image shows the male genitalia. The external iliac artery is a branch of the common iliac artery which arises in the pelvis superior to the structure indicated by the blue arrow. The external iliac artery passes beneath the inguinal ligament to become the femoral artery and supplies the lower limb. The arrow points to the inguinal canal on the right side. This is a short passage found in the lower abdominal wall, superior to the inguinal ligament, which allows the passage of various structures from the abdominal wall to the external genitalia.
name: External iliac artery
label: e
answer: no
explanation: This image shows a dissection of the anterior surface of the lower abdomen and the superior aspect of the right lower limb. The right side of the image shows the male genitalia. The inguinal ligament represents the white band of tissue formed by the aponeurosis of the inferior aspect of the external oblique muscle, and runs from the anterior superior iliac spine to the pubic tubercle. The arrow points to the right inguinal canal. The floor of the inguinal canal is formed by the inguinal lugaement and the lacunar ligament medially. The inguinal canal is a short passage found in the lower abdominal wall, superior to the inguinal ligament, which allows the passage of various structures from the abdominal wall to the external genitalia. For example, this is the passage by which the spermatic cord reaches the testicles in the scrotum. (The spermatic cord can be seen exiting the inguinal canal just inferior and medial to the arrow).
name: Inguinal ligament
label: b
answer: no
explanation: This image shows a dissection of the anterior surface of the inferior abdomen and the superior aspect of the right lower limb. The right side of the image shows the male genitalia. The arrow points to the right inguinal canal. This is a short passage found in the lower abdominal wall, superior to the inguinal ligament, which allows the passage of various structures from the abdominal wall to the external genitalia. For example, this is the passage by which the spermatic cord reaches the testicles in the scrotum. (The spermatic cord can be seen exiting the inguinal canal just inferior and medial to the arrow).
name: Inguinal canal (right)
