Hyaline Cartilage

found at the ends of bones that are located at movable joints.

When chondrocytes divide and form new matrix, it leads to an expansion of the cartilage tissue from within. This process is called:

interstitial growth.

What is the most common type of cartilage found between bones in freely moveable joints?

hyaline cartilage

The axial skeleton includes:

ribs.

Which of the following is mismatched?

Short bones: examples include the vertebrae

Bones do not have a role in

glycogen production.

What bone shape is the patella?

short bone

Which of the following is a bone projection?

Trochanter

Which of the following is stored in bones?

Phosphate

Osteoblasts:

form new bone.

In adults, yellow marrow is located:

in the medullary cavity of the long bones.

In adults, hematopoietic tissue is mainly found in:

the hip bones.

The osteon is:

the structural unit of compact bone

The notable hardness of bone is attributed to:

the presence of inorganic hydroxyapatites

The epiphyseal plate is:

where bone elongation occurs.

Which of the following is unlikely to trigger bone remodeling?

Glucagon

What is osteoid?

the organic part of the matrix of bone

What is the structural unit of compact bone?

osteon

During infancy and childhood, the most important stimulus of epiphyseal plate activity is:

growth hormone.

Which of the following is correctly matched?

Compound fracture: the bone ends penetrate the skin

Which bone cells form bone?

osteoblasts

What is endochondral ossification?

the formation of bone from pre-existing hyaline cartilage models

What indicates that a long bone has reached its adult length?

closure of the epiphyseal plate

The correct order (from start to finish) of fracture repair is:

Hematoma formation, fibrocartilaginous callus formation, bony callus formation, and bone remodeling.

The main role of the appendicular skeleton is to protect and support body parts

False

What controls bone remodeling?

mechanical stress and hormones

What is the final stage in the healing of a bone fracture?

bone remodeling

Choose the correct pairing.

Paget's disease: excessive and haphazard bone deposition and resorption

Flat bones consist of compact bone sandwiched between spongy bone.

False

Which of the following refers to a bone disorder found most often in the aged and resulting in the bones becoming porous and light?
