Locomotion And Movement

In humans, femur or the thigh bone is the longest bone of the body. It articulates with the acetabulum to form the hip joint.

Scapula is the largest of the bones that make up each half of die pectoral girdle. It is a triangular flat bone situated in the dorsal part of the thorax between second and seventh rib.

Myosin has two fragments, light meromyosin (LMM) and heavy meromyosin (HMM). HMM consists of two globular sub fragments (S-l) and one rod shaped fibrous sub fragment (S-2). Each S-l segment contains an ATPase site and a binding site for actin.

Our vertebral column is formed by 26 serially arranged units called vertebrae and is dorsally placed. It extends from the base of the skull and constitutes the main framework of the trunk. The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions starting from the skull.
