How to Stretch the Psoas Muscle

The psoas (sō-ŏz) muscle is approximately 16 inches long. It begins at both sides of the 12th thoracic vertebrae of the back, and stretches all the way down to each of the legs, where it makes a final connection with the lesser trochanter.

Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy. The transpyloric plane and McBurney’s point are among the marked locations. Locations of specific organs: The following vertebral levels are generally given by the middle of the vertebral body: The oblique fissure of the right lung goes from the spinal process of thoracic vertebra 3 towards the navel The horizontal fissure goes along the 4
