The tarsals are the bones of the:

foot

Which of the following is not a function of the skeletal system?

Anything that's not support, protection, movemnt, storage, and hematopoiseis

Nutrients pass from the blood vessels to the bone cells by way of the :

Canaliculi

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

Endosteum

Endosteum

a bone can grow as long as this remains

Epiphyseal plate

The end of long bones are called the:

Epiphysis

Osteclasts are the bone-forming cells

False

Osteoblasts are the bone-resorbing cells.

False

The epiphysis is the hollow area in the shaft of the bone where marrow is stored.

False

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

The concentric rings surrounding the central canal of an osteon are called lamella.

True

true

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