what is a fossa?

•  a depressed area that is often found on flat bones
• a hole that forms in the bone 
• a joint 
• a bone located in the hind leg of large animals 

What are the three major regions of the long bone? 

• the epiphysis, the metaphysis, and the diaphysis
• epistasis, metastasis and diastasis 
• the top middle and bottom 

The epiphysis

• is usually the portion of the bone that is covered with articular (joint) cartilage
• is the shaft of a long bone.
• is found between the mepiphysis and the diaphysis, providing a gradual, broadening transition between the two.

The diaphysis

• is the shaft of a long bone.
• is usually the portion of the bone that is covered with articular (joint) cartilage
• is found between the epiphysis and the diaphysis, providing a gradual, broadening transition between the two.

The metaphysis

• is found between the epiphysis and the diaphysis, providing a gradual, broadening transition between the two.
• is the shaft of a long bone.
• is usually the portion of the bone that is covered with articular (joint) cartilage

The wall of the diaphysis is composed of?

• tightly compact (cortical) bone. 
• cartilage 
• bone marrow 

The cortical bone of the diaphysis forms a central canal called the medullary cavity, which contains the bone marrow.

• True 
• False

Bones in a developing fetus start off as layers of?

• fibrous connective tissue and cartilage.
• underdeveloped bone marrow cells 
• cordical bones

The epiphyseal plate is made up of cartilage and osteoblasts.

• true 
• false

what is a fracture?

• a breakage of the bone 
• a crack in the bone 
• a displacement of the bone
