The point at which the testes make contact with the internal abdominal oblique, this portion of the oblique is:

Answer 31

Skeletal muscle portion

Question 32

The skeletal muscle portion of the internal abdominal oblique that the testes come into contact with, will form a new inguinal ring called the:

Answer 32

Middle inguinal ring

Question 33

At the point at which the middle inguinal ring is formed, what occurs with internal abdominal oblique muscles?

Answer 33

Stretches out and forms cremaster muscle

Question 34

Why do males have a cremaster muscle when this is absent in females?
