ConXport Human Male Pelvis Section (2 Parts), This median section model shows the normal position of male genital organs with bladder and rectum in the male pelvis. Dissectible into 2 parts. The human male pelvis is a complex and essential structure that plays a crucial role in supporting the body's weight, protecting internal organs, and facilitating movement. It consists of several bones and joints that work together to create a strong yet flexible framework. The male pelvis is composed of three main bones: the ilium, ischium, and pubis. These bones fuse together at the acetabulum, forming a cup-shaped socket that articulates with the head of the femur to create the hip joint. The sacrum, a triangular bone at the base of the spine, also contributes to the posterior portion of the pelvis.
