What is the insertion point of the rectus abdominis muscle?

The insertion point of the rectus abdominis muscle is correctly identified as the xiphoid process of the sternum and the cartilages of ribs 5-7. The rectus abdominis is a key muscle in the abdominal area, primarily involved in flexing the lumbar spine and stabilizing the pelvis and spine during movements.

By attaching at the xiphoid process and the lower ribs, this muscle plays a crucial role in various functional activities, such as bending forward and maintaining posture. Understanding the anatomy of this muscle, including its origin and insertion points, is essential for effective assessment and treatment in sports massage therapy.

Other potential options do not represent the actual insertion of the rectus abdominis; the greater trochanter is related to the hip and not the abdominal muscles, the iliac crest is an origin point for various muscles but not the rectus abdominis, and the aponeurosis of the linea alba is a connective tissue structure running down the midline of the abdomen but not a direct insertion point for the muscle in question.

Thus, the correct identification of the insertion points helps clarify the muscle's functional anatomy in sports massage practice.
