The two primary muscles that help maintain the pelvis in its correct centered position are the gluteus medius and the iliopsoas. The gluteus medius, located on the outer surface of the pelvis, stabilizes the hip during movement, while the iliopsoas, which consists of the psoas major and iliacus muscles, is crucial for hip flexion and stabilizing the lumbar spine. Together, these muscles contribute to pelvic alignment and overall stability during various activities.
The hip muscles play a crucial role in walking by providing stability, support, and power to the movement of the legs and pelvis. They help to control the movement of the hip joint and facilitate the swinging motion of the legs during each step.
The rectus abdominis: flexes the trunk, compresses the abdomen and stabilizes the pelvis External oblique:unilaterally: contra lateral rotation and ipsilateral( same side) side bending Bilaterally: flexes the trunk, compresses abdomen, and stabilizes the pelvis Internal oblique: unilaterally, ipsilateral side bending and rotation Bilaterally: flexes trunk, compresses abdomen, and stabilizes the pelvis The transverse abdominis: unilaterally rotates the trunk ipsi laterally Bilaterally: compresses the abdomen
Vestigal Structures.
The thighs protect several vital structures, including the femur bone, major blood vessels, and nerves that run from the hip to the knee. They also safeguard muscles critical for movement, such as the quadriceps and hamstrings. Additionally, the thigh area supports and stabilizes the pelvis and lower body during activities like walking, running, and standing. Overall, the thighs play a crucial role in both protection and mobility.
iliopsoas....
The edge of the pelvis refers to the bony prominence on the side of the pelvis known as the iliac crest. It serves as an attachment site for several muscles and ligaments and helps support the weight of the body when standing.

When walking, the major muscles targeted are the quadriceps, hamstrings, glutes, calves, and hip flexors. These muscles work together to move and stabilize the body during the walking motion.
