Canaliculi
The thin fibrous membrance that lines the medullary cavity is called the:

The metacarpals are the bones of the foot.
False
The periosteum lines the medullary cavity.
False
The tibia and fibula are the bones of the lower arm.
False
Small spaces in the bone matrix where bone cells are located
Lacunae
The bone cells in the Haversian system are found in little spaces called:
Lacunae
The hollow shaft of a long bone is called the:
Medullary cavity
Trabeculae are:
Needle like threads of spongy bone that surround a network
tough connective tissue surrounding the shaft of long bones
Periosteum
The red bone marrow is important in the skeletal function of:
Producing blood hematopoiesis
Canaliculi are small canals that help supply the bone cells with food and oxygen.
True
Chondrocytes are cartliage cells.
True
The articular cartliage covers and cushions the ends of the bones.
True

true
The storage of calcium is an important function of the skeletal system.
