Question 1

Which of the following statements about the functions of the paranasal sinuses is False ?

Accepted Answer

All of the statements about the functions of the paranasal sinuses are true. They provide an extensive area of mucous epithelium, make the skull bones lighter, secrete mucus that enters the nasal cavities, and support cilia that move the mucus.

Question 2

What process is the insertion site for the temporalis muscle?

Accepted Answer

The temporalis muscle inserts at the coronoid process of the mandible. This muscle is involved in elevating the mandible, thus playing a crucial role in the chewing process.

Question 3

The hyoid bone is suspended by ________.

Accepted Answer

The hyoid bone is unique in that it is suspended by ligaments. These ligaments attach the hyoid bone to the styloid process of the temporal bone and to the thyroid cartilage, allowing it a degree of movement necessary for swallowing and speech.

Question 4

A bent nasal septum that slows or prevents sinus drainage is known clinically as a ________ septum.

Accepted Answer

A deviated nasal septum is one that is crooked or off-center, which can cause obstruction and difficulty with sinus drainage.

Question 5

As the result of an accident, Bill suffers a dislocated jaw. This injury would involve the

Accepted Answer

A dislocated jaw typically involves the displacement of the condylar process of the mandible, which is the portion of the jaw that articulates with the temporal bone of the skull. The other options listed are not typically involved in this type of injury.

Question 6

You witness one of your friends in a fight. Your friend Gregg is hit in the jaw and when looking at him, his face looks misaligned. You immediately take him to the emergency room and are not surprised to learn that he has a broken

Accepted Answer

The mandible is the only bone listed that is part of the jaw, which would cause a misaligned face if broken. The temporal bone, zygomatic bone, external auditory meatus, and clavicle are not part of the jaw and would not cause a misaligned face.

Question 7

The hyoid bone

Accepted Answer

The hyoid bone attaches to tongue muscles, is linked to the styloid process by a ligament, and is located superior to the larynx. Therefore, all three statements are correct and the best choice is D - all of the above.

Question 8

If there were no paranasal sinuses, all of the following would be True , except

Accepted Answer

The ability to sneeze is not directly related to the presence of paranasal sinuses. Sneezing is a reflex to clear the nasal passage, which would still occur without sinuses.

Question 9

The most significant skull growth occurs before the age of

Accepted Answer

The answer of The most significant skull growth occurs before...

Question 10

Each of the following bones is a component of the orbital complex, except the ________ bone.

Accepted Answer

The nasal bone is not a component of the orbital complex. The other four bones listed (lacrimal, sphenoid, ethmoid, and frontal) are all part of the orbital complex, which encloses and protects the eyeball. The nasal bone is located in the nasal region of the skull and is involved in the formation of the bridge of the nose.

Question 11

A nerve that carries sensory information from the teeth and gums of the lower jaw passes through the

Accepted Answer

The nerve that carries sensory information from the teeth and gums of the lower jaw is the inferior alveolar nerve. It enters the mandible through the mandibular foramen and then passes through the mandibular canal, which runs through the ramus of the mandible. Choice D is the correct answer as it identifies the correct location where the nerve enters the mandible.

Question 12

While volunteering in an outpatient clinic for underprivileged families in your neighborhood, you observe the nurse assessing an infant. The mother had complained about the baby not eating and having several episodes of diarrhea lasting three days. You know the nurse suspects possible dehydration when she

Accepted Answer

The nurse checks the anterior fontanel for depression because a sunken fontanel can be a sign of dehydration in infants.

Question 13

What organ is located in the lacrimal fossa?

Accepted Answer

The lacrimal fossa houses the lacrimal gland, which produces tears. Therefore, the correct answer is C, tear gland.

Question 14

The paranasal sinuses are located in all of the following bones, except the

Accepted Answer

The paranasal sinuses are located in the frontal, ethmoid, sphenoid, and maxillae bones, but not in the zygomatic bone.

Question 15

The bony portion of the nasal septum is formed by the

Accepted Answer

The bony portion of the nasal septum is formed by the perpendicular plate of the ethmoid bone and the vomer bone. Therefore, option C is the correct answer. The nasal bones do form a portion of the nose, but not the septum specifically. The perpendicular plate of the ethmoid bone also contributes to the septum. The sphenoid bone is not directly involved in forming the bony portion of the nasal septum.

Question 16

While visiting your friend who recently gave birth, she comments on her infant's soft spot. You think to yourself that the correct term for the "soft spot" located at the intersection of the frontal, sagittal, and coronal sutures is the

Accepted Answer

The "soft spot" located at the intersection of the frontal, sagittal, and coronal sutures is known as the anterior fontanel. This fontanel allows for the growth and expansion of the skull in infants, and typically closes by 18-24 months of age.

Question 17

The nasal complex consists of all of the following bones, except the

Accepted Answer

The nasal complex consists of the ethmoid, sphenoid, frontal, and maxillary bones, but not the zygomatic bone.

Question 18

Each of the following statements concerning the development of the skull is True , except that

Accepted Answer

The bones of the skull develop from multiple ossification centers, not a single ossification focus.

Question 19

Which of the following carries tears to the nasal cavity?

Accepted Answer

The nasolacrimal canal is a narrow passageway that carries tears from the lacrimal sac into the nasal cavity.

Question 20

The anterior fontanel is located

Accepted Answer

The anterior fontanel is the soft spot on a baby's head that is located where the frontal bone and parietal bones meet. Therefore, it is both posterior to the frontal bone and anterior to the parietal bones. Option D is the only answer choice that reflects this location.
