Sternal part -originates from the posterior aspect of xiphoid process. Costal part - originates from the internal surfaces of the lower costal cartilages and ribs 7-12. Lumbar part - originates from the bodies of vertebrae L1-L3 and intervertebral discs, the anterior longitudinal ligament and ...
Ribs are flat, narrow and curved bones of strips found in the chest of vertebrates. They are attached to the vertebrae on the dorsal side and to the sternum on the ventral side. This attachment forms an enclosed structure called the rib cage. Read on to
Human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship wit
The human skeleton, like that of other vertebrates, consists of two principal subdivisions, each with origins distinct from the others and each presenting certain individual features. These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendi...
Butterfly-shaped bone formed by the fusion of the 5 sacral vertebrae Articulates with the 2 hip bones posteriorly Each side articulates with the ilium via the sacroiliac joints. Coccyx : Terminal end of the spine Inferior to the sacrum An attachment for various muscles, tendons, and ligam...
Human muscle system, the muscles of the human body that work the skeletal system, that are under voluntary control, and that are concerned with movement, posture, and balance. Broadly considered, human muscle—like the muscles of all vertebrates—is ofte
to stabilize it in supporting the weight of the upper body; the joint’s motion is also limited by the irregular surfaces of the sacrum (the fused vertebrae of the lower spine), which closely articulate with the ilium (the uppermost of the three bones composing each half of the pelvis). ...
