Young children's bones have a greater risk of fracturing because of incompletely ossified bone.

Question 29

There are more bones in the appendicular skeleton than in the axial skeleton.

The cribriform plate is part of the sphenoid bone.

Question 36

The skull contains more than 25 bones.

Question 37

Before childbirth,the symphysis pubis softens.

Question 38

The largest of the bones making up the innominate bone is the ischium.

There are two arches of the foot-one lengthwise and one crosswise.

Question 42

The parietal bone is involved in three sutures-the lambdoidal,the squamous,and the coronal.

Question 43

The olecranon and coronoid fossae are markings of the scapula.

Question 44

False ribs attach only to the thoracic vertebrae.

Question 45

When the knee is flexed,the patella can be easily distinguished.

The vomer bone forms immovable joints with four other bones-the sphenoid,the palatine,the ethmoid,and the frontal.

Question 48

The lesser trochanter is a marking of the tibia.

Question 49

The bones of the skull form only sutures (immovable joints),not movable joints.

Question 50

Only the radius has a direct articulation with the bones of the wrist.

Question 51

Both the tibia and fibula articulate with the femur.

Question 52

Although the mandible seems to be one bone,it is the result of a fusion of two bones in infancy.

Question 53

The dens is found on the second cervical vertebra,or axis.

Question 54

The joint between the scapula and ribs is a fibrocartilage joint.

Question 55

The wrist consists of six irregular carpal bones.

Question 56

An open fracture is also known as a compound fracture.

Question 57

The number of thoracic vertebra is the same as the number of ribs.

Question 58

The xiphoid process and the manubrium are at opposite ends of the sternum.

Question 59

The sagittal suture joins the right and left parietal bones.
