Calcuim is needed for strong bone growth. Meaning all bones start off as cartilage (normally in the womb) and they gradually turn to hard bone (ossification) over a period of years. The scapula forms the posterior of the shoulder girdle. The structures of these bones are similar with respect to cortical bone thickness and the lack of bone marrow however, the osteogenesis of these two bones occurs via different ossification patterns 1. The scapula or shoulder blade is the bone that connects the clavicle to the humerus. How are bones formed? Bones are formed by the ossification of cartilage. Here we focused on the repair of two flat bones, the parietal bone and scapula. Leg - Femur, Tibia and Fibula Ankle - Talus and calcaneus (not shown above) Foot - Tarsals, Metatarsals and Phalanges. Pelvic girdle - Ilium, Pubis and Ischium. The main bones of the human skeleton are: The Skull - Cranium, Mandible and Maxilla Shoulder girdle - clavicle and scapula Arm - humerus, radius and ulna Hand - Carpals, Metacarpals and Phalanges Chest - Sternum and Ribs Spine - Cervical area (top 7 vertibrae), Thoracic (next 12), Lumbar (bottom 5 vertebrae), Sacrum (5 fused or stuck together bones) and Coccyx (the tiny bit at the bottom of the spine). functions to provide support, give our bodies shape, provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement and to produce red blood cells. The Human Skeleton - human skeleton is made up of 206 bones.
