Axial skeleton What is it? What's it include?

Runs through the medial part of the skeleton. - skull - ear ossicles - hyoid bone - sternum and ribs (thorax or thoracic cavity) - vertebral column

Appendicular skeleton

Contains - upper extremities and girdles - lower extremities and girdles

Pectoral girdle

Clavicle and scapula

Pelvic girdle

Ilium, ischium, pubic bone

Juggler notch is the?

Throat

True ribs. How many? Where do they attach?

From the top of sternum they are ribs 1-7. They attach directly to the sternum all attach posteriorly to the T. Vertebrae

False ribs. How many? Where do they attach?

- There are 5 false ribs - Ribs 8-10 attach to the superior costal cartilage. - ribs 11 and 12 are the floating ribs. They only attach to the T. Vertebrae. - all attach posteriorly to the T. Vertebrae

Glanoid cavity

A cavity located on the scapula. Head of humorous articulates here.

Ilium

Anterior. Heart shaped part of pelvis. Houses acetabular notch where the femur articulates with

Ischium

Posterior section of pelvis Houses the obturator foremen

Pubic bone

Meets at the midline in the pelvis region.

Describe a the process of healing a fracture...

``` 1- bleeding forms clot 2- periosteum(CT) - forms 3- fibril blasts form 4-osteoblasts form - helps fragments of bone form in blood clot. 5- fragments grow into bone ```

Osteoblasts

Bone forming cells
