The bone at D forms a joint with the temporal bone (temporomandibular joint) that allows the mouth to open, close, and move laterally.

Which letter represents the cervical curvature?

The cervical curvature includes the first seven vertebrae and is posteriorly concave. (A)

Which of the following pairings of letter to bone is INCORRECT?

The letter A indicates the frontal bone, not the parietal.

What bone marking is a hole in a bone?

foramen

22

The mandible is unique among the skull bones because of which of the following characteristics?

The mandible is the only bone of the skull that is not joined to the other bones of the skull by immobile sutures

The maxilla articulates with both the nasal bone and the vomer. (c)

Identify the bone(s) that form(s) the majority of the hard palate and a keystone bone of the face.

These bones, along with the palatine bones, form the hard palate. (a)

What is ultimately the fate of fontanels in a child or an adult skull?

They ossify, and in time become sutures.

A fontanelle __________.

allows for compression of the skull during birth, is a fibrous membrane, is found only in the fetal skull

Which vertebra does NOT have a body?

atlas

The __________ of a typical vertebra forms the rounded, central portion that faces anteriorly in the human vertebral column.

body

Which of the following bones are part of the axial skeleton?

bones of the face

The seven bones of the neck are called __________ vertebrae.

cervical

You pick up a vertebra to identify it and note that the transverse processes contain foramina. This unique feature identifies the vertebra as coming from the ________ region of the vertebral column.

cervical

Identify the anterior suture of the bone marking labeled A in the lateral skull view.

coronal suture

Which of these important processes is found on the highlighted bone?

coronoid process (This process, located anterior to the condylar process across the mandibular notch, is the insertion for the temporalis muscle, which is important in moving the jaw and chewing.)

Thoracic vertebrae differ from the other vertebrae in that they have ________.

costal facets

coxa (hip)

Eight bones make up the __________ , which encloses and protects the brain.

The frontal bone articulates with the parietal bone by means of the sagittal suture.

false

The largest and strongest bone of the face is the maxilla.

false

Fontanels are ________.

fibrous membranes in a fetal skull

What is the most specific term you could apply to the rib at D?

floating rib (This is a floating rib because it does not articulate with a costal cartilage and instead terminates in the body wall.)

This bone does not articulate with any other bone in the body. Muscles of the neck and tongue attach to it.

The __________ is the only bone in the body that does not directly articulate with any other bone.

hyoid bone

The hyoid bone is unique because it ________.

palatine bone

The sagittal suture connects the two _______________ bones.

parietal

Which of the following is NOT a function of the facial bones of the skull?

protect the brain from trauma

Which is the best description for the function of the cranial bones?

protects the brain

sagittal

The dens is part of the _______________ cervical vertebra.

second

sphenoid; pituitary

The suture that is found where a parietal and temporal bone meet on the lateral aspect of the skull is ________.

squamous

The __________, commonly referred to as the breastbone, is a flat bone formed by the fusion of three bones: the manubrium, the body, and the xiphoid process.

sternum

The xiphoid process is part of the _______________.

sternum

Identify the bone marking labeled B in the anterior skull view.

superior orbital fissure

The external acoustic meatus is located within the _______________ bone.

temporal
