THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Urethra: in females, the urethra is approximately 4 cm in length, it passes through the perineal membrane and opens as the external urethral orifice in the vestibule above the vaginal opening. Vagina: is situated behind the urethra. The perineal membrane in females is divided by urethra and vagina into two halves.

Detailed explanation-2: -Pubic symphysis joint (front): Your perineum begins at your pubic symphysis, the joint in the front of your pelvis that connects your left and right pelvic bones. Tailbone (back): Your perineum reaches from your pubic symphysis joint back to your tailbone (coccyx).

Detailed explanation-3: -At the apical point – where the membrane attaches to the arcuate ligament of the pubic symphysis – it is referred to as the transverse perineal ligament (pubourethral ligament in females).

Detailed explanation-4: -The pubic symphysis is found on the anterior side of the pelvis and is the anterior boundary of the perineum. The pubic bones form a cartilaginous joint in the median plane, the symphysis pubis. The joint keeps the two bones of the pelvis together and steady during activity.
