Bone develops from spindle-shaped cells called

periosteum.^
are large cells, present in the (^)
(^) cavities of bone, which function in the reabsorption (^)
(^) of bone. (^)
ossification is a process in (^)
(^) which dense connective tissue or membranes are (^)
(^) replaced by deposits of inorganic calcium. (^)
The “replacement” of cartilaginous structures with (^)
bone is called ossification. (^)

Haversian canals are surrounded by

The bridge of the nose is made up of the paired (^)
(^) bones. (^)
The hard palate of the roof of the mouth is made up (^)
of the two bones. (^)
The bone, found in the axial (^)
skeleton, has no articulations with other bones and (^)
functions as a support for the tongue. (^)
The first cervical vertebra is called the^

- There are 12 pairs of ribs. The upper seven pairs
articulate directly with the sternum and are called^
ribs; the lower five pairs
do not directly join the sternum and are called^
ribs.
True or False
T F 1. Cartilage actually turns into bone during
ossification.
T F^ 2. The protein matrix of bone is responsible for^
its elasticity and the salts deposited in the
matrix prevent crushing.
T F 3. The more strain on a bone, the less the bone
will develop.
T F 4. It is possible for crooked bones in children
to become straight due to the continued
process of reabsorption.
T F^ 5. The proper calcium ion concentration of^
the blood is controlled and maintained by
the thyroid and parathyroid glands of the
endocrine system.
T F 6. The foramen magnum is the largest orifice in
the skeleton and is found at the base of the
parietal bone.
