Pelvic Anatomy Muscles

Deep urogenital diaphragm layer. They form a large sheet of skeletal muscle that is thicker in some areas than in others.

Pelvis Hip Anatomy

The pelvic girdle is formed by a single hip bone.

Pelvic anatomy muscles. They support the pelvic organs especially during increases in intra abdominal pressure and also aid in urinary and faecal continence. Innervated by sacral nerve roots s3 s5. Anterior pubic bodies of the pelvic bones.

This muscle is responsible for holding in urine and feces. They form a large sheet of skeletal muscle that is thicker in some areas than in others. The muscles of the pelvis form its floor.

It is enervated by the nerve to the obturator internus. The iliococcygeus has thinner fibers and serves to lift the pelvic floor as well as. Innervated by the pudendal nerve.

The right and left hip bones plus the sacrum and the coccyx together form the pelvis. Lying exposed between the protective bones of the superiorly located ribs and the inferiorly located pelvic girdle the muscles of this region play a critical role in protecting the delicate vital organs within the abdominal cavity. There are many muscles that form the pelvic floor including puborectalis pubococcygeus iliococcygeus and coccygeus.

The hip bone attaches the lower limb to the axial skeleton through its articulation with the sacrum. It originates from the ilium and ischium. Posteriorly ischial spines of the pevlic bones.

This muscle makes up most of the levator ani muscles. The pelvic floor consists of three muscle layers. There are many organs that sit in the pelvis including much of the urinary system and lots of the male or female reproductive systems.

Innervated by pudendal nerve. Laterally thickened fascia of the obturator internus muscle known as the tendinous arch. The skin tissues and organs in the pelvis are supplied by the vasculature of the pelvis and innervated by many nerves of the pelvis including the pudendal nerve.

The floor of the pelvis is made up of the muscles of the pelvis which support its contents and maintain urinary and faecal continence. Female pelvis muscles puborectalis. The muscles of the pelvic floor are collectively referred to as the levator ani and coccygeus muscles.

These muscles have attachments to the pelvis as follows. This muscle forms most of the lateral wall of the pelvis and traverses through the lesser sciatic foramen attaching to the greater trochanter of the femur. The muscles of the abdomen lower back and pelvis are separated from those of the chest by the muscular wall of the diaphragm the critical breathing muscle.
