a. They form the base of the skull.
b. The four largest sutures occur where the parietal bones join to other bones.
c. They are paired.
d. They form the bulk of the cranial vault
The base of the cranium (skull) is formed by the occipital bone (not the parietal bones).
Which of the following bones is NOT part of the orbit?
a. the zygomatic bone
b. the temporal bone
c. the frontal bone
d. the maxilla
The temporal bone is lateral and too far posterior to contribute to the orbit
Which of the following bones do NOT contain a paired paranasal sinus?
a. the frontal bones
b. the zygomatic bones
c. the ethmoid bones
d. the sphenoid bones
The zygomatic bones do not have paranasal sinuses
Which of the following is NOT a facial bone?
a. the zygomatic bone
b. the vomer bone
c. the nasal bone
d. the maxilla
e. the sphenoid bone
The sphenoid bone is a cranial bone.
The vomer and ethmoid bones form part of the __________.
a. lacrimal fossa
c. nasal septum
d. lateral walls of the nasal cavity
The vomer and ethmoid bones form the bony parts of the nasal septum. The vomer forms the inferior portion of the septum. The perpendicular plate of the ethmoid bone forms the superior portion of the septum.
How many lumbar vertebrae are there in a typical adult skeleton?
A typical adult skeleton has 5 lumbar vertebrae, 12 thoracic vertebrae, and 7 cervical vertebrae.
Which of the following pairs is correctly matched?
a. lumbar vertebrae; short, flat spinous processes
b. thoracic vertebrae; triangular vertebral foramen
c. lumbar vertebrae; bifid spinous processes
d. thoracic vertebrae; transverse foramen
e. cervical vertebrae; rib facets.
The lumbar vertebrae have large, flattened spinous processes as a result of being attached to the large muscles in the back.
Which of the following bones does NOT fit with the other listed bones?
a. the true ribs
b. the sternum
c. the clavicle
d. the vertebrae
The clavicle is part of the APPENDICULAR skeleton.
ach of the 12 ribs articulates with one vertebra. Is this statement true or false?
Each rib articulates with two separate vertebrae. The tubercle of the rib articulates with the rib facet of a thoracic vertebra on the transverse process. The head of the rib articulates with the bodies of two separate vertebrae.
Which of the following bones are part of the axial skeleton?
a. bones of the pectoral girdles
b. bones of the face
c. bones of the lower limbs
d. bones of the the pelvic girdle
The bones of the skull including facial bones are part of the axial skeleton.
The __________ is the only bone in the body that does not directly articulate with any other bone.
a. temporal bone
b. hyoid bone
The hyoid bone does not articulate directly with any other bone. Instead, it is anchored by the stylohyoid ligaments to the styloid process of the temporal bones.
Which of the following would be most associated with process of warming, humidifying, and filtering the air we inhale?
a. hyoid bone
b. the nasal cavity
c. the cranial bones
d. the bones comprising the orbits
Which is the best description for the function of the cranial bones?

b. house the special sense organs
c. allow introduction of food into the digestive system
d. protect the brain
The sphenoid bone is sometimes referred to as a "key stone" of the skull. This is due to the fact that ________.
a. the intricate shape of the sphenoid makes it critical to the distinct characteristics of the individual human face
b. the sphenoid is wedged in the superior most portion of the skull and supports all of the other bones below (excluding the mandible)
c. the sphenoid is in the center of the skull and it articulates (joins) with all of the other bones of the skull (excluding the mandible)
d. the sphenoid bone is solid like a stone and provides the strength necessary to support the skull
sella turcica is part of the ________ bone and houses the ________ gland.
a. sphenoid; thymus
b. ethmoid; thymus

b. the skull, vertebral column, and rib cage
c. arms, legs, hands, and feet
d. the skull, vertebral column, and pelvis
