Bones of the upper limb and pectoral girdle and the bones of the lower limbs and the pelvic girdle or examples of what skeletal region
Appendicular skeleton
What bone is roughly cube shape, like the ankle and wrist bone
Short bones
Sternal bones, ribs, scapula, clavicle, most of the cranial bones or examples of what type of bone

Sutural (wormian) bones
Suture that crosses the crown of the head from right to left and joins the frontal bone to the perietal bone
Coronal suture
Sutured laterally side connects the Perio bone to the Temporel bone
Squamous suture
Suture that connects the two Parietal bones
Sagittal suture
Suture connects the parietal bone to the occipital bone
Lambdoidol suture
How many bones are in the skull
22
Blank bone is a pair. It is on the right and left of the top part of the skull

Ethmoid bone
Bone is not a pair it is posterior cranial base
Occipital bone
