Question 1

Which of the following indicates temporomandibular joint (TMJ)pathology?

Accepted Answer

Malocclusion of the teeth can be a result of TMJ pathology, as the joint is responsible for the movement and alignment of the mandible (lower jaw) in relation to the maxilla (upper jaw). Dysfunction of the TMJ can lead to alterations in the bite, causing malocclusion. Mastication of the teeth (A), occlusion of the teeth (C), and a fractured tooth (D) do not necessarily indicate TMJ pathology.

Question 2

The nasal septum is formed on its posterior half by the vomer bone and the perpendicular plate of which of the following?

Accepted Answer

The perpendicular plate of the ethmoid bone forms the posterior half of the nasal septum, while the vomer bone forms the inferior and posterior portion. The hard and soft palates and maxillary bones do not contribute to the formation of the nasal septum.

Question 3

The middle ear is connected to the nasal passages of a patient via which of the following?

Accepted Answer

The Eustachian tube connects the middle ear to the nasal passages, allowing for equalization of pressure between the middle ear and outside environment. The external auditory canal is the part of the ear that leads to the eardrum, the internal auditory canal connects the inner ear to the brainstem, and the vestibular cochlea is a structure in the inner ear that is involved in balance and spatial orientation.

Question 4

What structure is located anteriorly in the neck,can be palpated,and functions as the tongue's attachment site?

Accepted Answer

The hyoid bone is located anteriorly in the neck, can be palpated, and functions as the tongue's attachment site. The thyroid cartilage and cricoid cartilage are also located in the neck, but they do not serve as the tongue's attachment site. The lesser cornua are part of the hyoid bone but alone do not function as the tongue's attachment site.

Question 5

A patient's superior row of teeth are fixed within what structure?

Accepted Answer

The superior row of teeth are fixed within the alveolar process, which is a part of the maxillary bone.

Question 6

Which of the following describes the area of a patient's mouth that represents everything past the teeth and leading to the trachea?

Accepted Answer

The oral cavity is the correct term for the area of the mouth that is beyond the teeth and leads towards the trachea. It encompasses the space inside the mouth, including the tongue, gums, and the entrance to the throat.

Question 7

What structure covers the larynx superiorly?

Accepted Answer

The thyroid cartilage covers the larynx superiorly and is commonly referred to as the "Adam's apple" in men.

Question 8

What is "swimmer's ear" medically known as?

Accepted Answer

Swimmer's ear is medically known as otitis externa, which is inflammation or infection of the external ear canal.

Question 9

What are the small rough projections found on the surface of a patient's tongue that assist in the movement of food during chewing?

Accepted Answer

Papillae are small rough projections found on the surface of the tongue that assist in the movement of food during chewing. They also contain taste buds, which are responsible for sensing different flavors. Vermilion is the red-colored border of the lips, and papules are small, raised bumps on the skin that are not related to the tongue.

Question 10

The cochlea and the semicircular canals sit within a bony,fluid-filled labyrinth formed within which structure?

Accepted Answer

The temporal bone houses the bony labyrinth of the inner ear, which includes the cochlea and semicircular canals.

Question 11

Which of the following structures would be damaged first by a severe blow to the thyroid cartilage?

Accepted Answer

The thyroid cartilage is a part of the larynx, so a severe blow to it would most likely damage the larynx first. The trachea, esophagus, and pharynx are located adjacent to the thyroid cartilage, but the larynx would be the most directly affected.

Question 12

The maxilla does not articulate with which of the following?

Accepted Answer

The maxilla bone articulates with many bones such as the zygoma, nasal, and lacrimal bone, but not with the mandible bone. The mandible bone articulates with the temporal bone to form the temporomandibular joint.

Question 13

How many permanent teeth would a patient have,assuming no previous trauma or injury to the mouth?

Accepted Answer

The human dentition consists of 32 permanent teeth, including 16 in the maxilla (upper jaw) and 16 in the mandible (lower jaw). This includes 8 incisors, 4 canines, 8 premolars, and 12 molars.

Question 14

What is the shape of the external ear-which is maintained by an accumulation of cartilaginous tissue-called?

Accepted Answer

The external ear is made up of the auricle (also known as the pinna), which is the visible part of the ear that is shaped like a curved funnel. This shape is maintained by an accumulation of cartilaginous tissue.

Question 15

What connects the tongue from its underside to the floor of the oral cavity?

Accepted Answer

The lingual frenulum is a thin strip of tissue that connects the underside of the tongue to the floor of the oral cavity.

Question 16

Which type of tooth luxation is marked by a depression into the alveolar process relative to the contiguous teeth and to its match on the opposite side?

Accepted Answer

Intruded tooth luxation is marked by a depression into the alveolar process relative to the contiguous teeth and to its match on the opposite side. Extruded tooth luxation is marked by the tooth being pushed out of the socket, while avulsed tooth luxation is marked by the tooth being completely knocked out of the socket. Fractured tooth luxation is marked by a break in the tooth structure.

Question 17

What is the outermost covering of a tooth?

Accepted Answer

Enamel is the outermost and hardest covering of a tooth, responsible for protecting the underlying dentin and pulp from wear and decay.

Question 18

What anchors a tooth's root to the alveolar process?

Accepted Answer

Cementum is a specialized connective tissue that covers the root of the tooth and anchors it to the bone of the alveolar process. It also serves as a protective layer for the underlying dentin. Dentin, pulp, and enamel do not play a direct role in anchoring the tooth's root to the alveolar process.

Question 19

What artery is typically associated with a patient bleeding anteriorly as the result of a nasal fracture?

Accepted Answer

The anterior ethmoid artery is typically associated with a patient bleeding anteriorly as the result of a nasal fracture. This artery supplies the anterior part of the nasal septum and can be damaged in nasal fractures, leading to anterior nosebleeds.

Question 20

The articular disk found in the TMJ is _________ on its superior surface and ________ on its inferior surface.

Accepted Answer

The answer of The articular disk found in the TMJ...
