Between the Pelvis and the Ribcage: The Abdominal Muscles. The abdominal muscles are the main bridge between the pelvis and the rib cage besides the lower spine. Our bones hold us up and our muscles move us. Ligaments connect bones to bones and tendons connect muscles to bones. Throughout most of the body there is a closely quartered network of bones along with muscle, ligament, tendons. Each supports the other in the alignment of the body .
Tendons connect the muscle belly to bone and they attach to the bone periosteum-more connective tissue that covers all bones. Contraction of the muscle belly pulls on the tendon and in turn, the bone it is attached to. Limb muscles (such as the biceps brachii in the upper arm) have two attachments to bone.The proximal or origin is the attachment closest to the trunk. The distal or insertion is the attachment furthest from the trunk.Trunk muscles (such as the rectus abdominus in the stomach) also have two attachments-superior (closer to the head) and inferior (further from the head). A closer look at muscle anatomy shows that each muscle belly is made up of muscle cells or fibres.imb muscles (such as the biceps brachii in the upper arm) have two attachments to bone. The proximal or origin is the attachment closest to the trunk. The distal or insertion is the attachment furthest from the trunk.
