Question

What muscles connect the pelvis and perineum?

Answer 1

Ans:

The pelvis is inferior most part of the trunk consisting of the pelvic girdle and perineum. It supports the urinary and reproductive organs. The bony framework of the pelvis is called the pelvic girdle. It is composed of the two hip bones and the sacrum. Pelvic bones are held together by the two main joints of the pelvis; the pubic symphysis and the sacroiliac joint, and reinforced by pelvic muscles. The pelvic cavity opens superiorly to, and is continuous with, the abdominal cavity through the pelvic inlet. Whilst the pelvic outlet is enclosed by the pelvic floor, made of the pelvic diaphragm. The perineum is the part of the pelvis which contains the external genitalia and anus. It is inferior to the pelvic diaphragm. Regarding the surface anatomy, the perineal area is the region between the thighs, extending from the pubic symphysis anteriorly to the gluteal folds posteriorly.

Muscles that connects the pelvis and perineum are tabulated below:
