This bone helps the tendons to glide over the bony surfaces and prevent excessive wear and tear and at the same time they act alter the direction of pull of the tendons. They are situated at the end of long bones of the limbs
Sesamoid bones
small fragments of bones between bones of the skull.
Wormian or sutural bones
are the abnormal calcifications in soft tissues
Heterotopic bones
Cartilages of the Larynx,
Trachea and Bronchi.
Fibrous skeleton of the
Heart
Splanchnic Skeleton
Bones with their cartilage and ligaments:
Axial skeleton
appendicular skeleton
Endoskeleton
This is located around the longitudinal axis of the body that is most of the bones of the axial skeleton constituted the central body core of the body, the axis
Axial Skeleton (80)
This is composed of bones found in the limbs and their corresponding girdles forming a total of
