The type of epithelial tissue that lines the oral cavity is called
A. stratified squamous epithelium.
B. simple columnar epithelium.
C. simple cuboidal epithelium.
D. pseudo-stratified columnar epithelium.
A. stratified squamous epithelium.
RATIONALE: Stratified squamous epithelium lines the cavity. Simple columnar epithelium is tall
and narrow; it lines the intestines and cervix of the uterus. Simple cuboidal epithelium is cubical
in shape and lines the ovaries. Note that pseudo-stratified columnar epithelium appears
stratified, but is in fact, only one layer. Pseudo-stratified epithelium lines is found in the trachea.
The cheekbone is composed of the
A. The temporal process of the zygomatic bone and the zygomatic process of the temporal bone
B. The zygomatic process and the zygomatic bone
C. The palatine processes
D. The frontal process and the frontal bone.
A. The temporal process of the zygomatic bone and the zygomatic process of the temporal bone
RATIONALE: The zygomatic arch (cheekbone) is composed of the temporal process of the
zygomatic bone and the zygomatic process of the temporal bone. The zygomatic process
articulates with the zygomatic bone and completes the infraorbital rim. The palatine processes
articulate with each other to form the anterior major portion of the hard palate and the median
palatine suture. The frontal process articulates with the frontal bone, forming the medial orbital
rim with the lacrimal bone.
What bones form the lateral walls of the skull?
A. The cranial bones
B. The occipital bone
, C. The temporal bones
D. The parietal bones
C. The temporal bones
RATIONALE: The temporal bones (paired bones) form the lateral walls of the skull. The cranial
bones, or neurocranium, (eight bones) surround the brain; four singular bones, two paired
bones. The occipital bone (single bone) forms the posterior portion of the skull. The parietal
bones (paired bones) constitute a large part of the vault and sides of the cranium.
The surface of the condyle articulates with the
A. external acoustic meatus.
B. styloid process.
C. coronoid notch.
D. temporal bone.
D. temporal bone
RATIONALE: The condyle articulates with temporal bone, forming the moving part of the TMJ.
The external acoustic meatus is the ear canal and does not rotate within the condyle. The
styloid process, a pointed piece of bone extending below the ear, projects down and forward
from the inferior surface of the temporal bone. The coronoid notch, also called the coronoid
process, is a concavity on the anterior border of the ramus of the mandible.
A structure in the cell that contains a single, circular DNA, and synthesizes adenosine
triphosphate (ATP) is the
A. mitochondria.
B. lysosome.
C. endoplasmic reticulum.
D. Golgi apparatus.
A. mitochondria
RATIONALE: Mitochondria are powerful cellular organelles that contain a single circular DNA,
and synthesize the body's primary source of energy, adenosine triphosphate (ATP). Lysosomes
contain digestive enzymes and lead the breakdown of foreign substances by the process of
phagocytosis. Endoplasmic reticulum is involved in protein synthesis and the transport of
nutrients to the nucleus. The golgi apparatus stores, packs, and transfers proteins and other
cellular components to the exterior of a secretory cell.
