Arthritis may affect the disc or the bony part of the TMJ.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Arthritis is a condition that causes inflammation and damage to the joints. The temporomandibular joint (TMJ) is the joint that connects the jawbone to the skull, and it can be affected by arthritis. Arthritis can impact both the disc, which acts as a cushion between the jawbone and the skull, as well as the bony part of the TMJ. Therefore, it is true that arthritis may affect both the disc and the bony part of the TMJ.Rate this question:

The articular disc is tightly attached to the medial and lateral poles of the condyle.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The articular disc is a structure located in the temporomandibular joint (TMJ) that helps to cushion and stabilize the joint during movement. It is indeed tightly attached to the medial and lateral poles of the condyle, which are the rounded ends of the mandible bone that articulate with the skull. This attachment allows the articular disc to move smoothly with the condyle during jaw movements, providing support and preventing excessive friction or dislocation. Therefore, the statement is true.Rate this question:

Irregular movements of the disc may make popping sounds.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Irregular movements of the disc can cause the bones in the joint to rub against each other, resulting in a popping sound. This can occur in various joints in the body, including the spine, jaw, and knees. It is often associated with conditions such as temporomandibular joint disorder (TMJ) or joint hypermobility syndrome. Therefore, it is true that irregular movements of the disc can lead to popping sounds.Rate this question:

Neck spasms; tMJ pain
Correct Answer
referred painExplanation
Referred pain is a phenomenon where pain is felt in a different area of the body than the actual source of the pain. In this case, the individual is experiencing neck spasms and TMJ pain. The term "referred pain" suggests that the pain in the neck and TMJ area may be caused by a different underlying issue in another part of the body. It is possible that the source of the pain is located elsewhere, but is being perceived as neck spasms and TMJ pain.Rate this question:
- 11.
Grinding sensation in TMJ
Correct Answer
arthritisExplanation
The grinding sensation in the TMJ (temporomandibular joint) is commonly associated with arthritis. Arthritis is the inflammation and stiffness of the joints, which can affect the TMJ as well. This condition can cause pain, swelling, and difficulty in jaw movement. The grinding sensation is often a result of the roughening or wearing down of the joint surfaces due to arthritis. Seeking medical advice and treatment from a healthcare professional is recommended to manage the symptoms and improve the condition.Rate this question:
- 12.
Attrition
Correct Answer
bruxismExplanation
Bruxism is the correct answer because it is a term used to describe the habit of grinding or clenching one's teeth. It is often done unconsciously during sleep or as a response to stress. Attrition, on the other hand, refers to the gradual wearing away of tooth structure due to factors such as age, tooth grinding, or improper alignment. While attrition can be a consequence of bruxism, it is not the specific term used to describe the grinding or clenching action itself.Rate this question:

Inability to close the mouth.
Correct Answer
subluxationExplanation
Subluxation refers to a partial dislocation of a joint, where the joint surfaces are not completely separated but are misaligned. In the context of the given statement, subluxation can cause the inability to close the mouth properly. This misalignment can occur due to various reasons such as trauma, joint hypermobility, or certain medical conditions. It can result in pain, limited range of motion, and difficulty in performing normal joint functions, including closing the mouth.Rate this question:

Which of the following is true about lateral excursions of the jaw?
- A.
They are controlled by the upper hear of the lateral pterygoid
- B.
They are controlled by the lower head of the lateral pterygoid
- C.
The jaw moves toward the side on which the laterla pterygoid contracts
- D.
If the jaw moves to the right, the condyle on the other side moves posteriorly
- E.
None of the above
Correct Answer
B. They are controlled by the lower head of the lateral pterygoidExplanation
The correct answer is that lateral excursions of the jaw are controlled by the lower head of the lateral pterygoid. The lateral pterygoid muscle is responsible for moving the jaw from side to side. It has two heads, the upper head and the lower head. The lower head of the lateral pterygoid specifically controls the lateral movements of the jaw. When this muscle contracts, the jaw moves towards the side on which the muscle is contracting. Therefore, the correct statement is that the lateral excursions of the jaw are controlled by the lower head of the lateral pterygoid.Rate this question:

Which structure prevents the condyle from moving too far anteriorly?
- A.
Articular eminence
- B.
TMJ capsule
- C.
Lower collageous lamina
- D.
Temporomandibular ligament
- E.
Both b and c
Correct Answer
E. Both b and cExplanation
Both the TMJ capsule and the lower collagenous lamina prevent the condyle from moving too far anteriorly. The TMJ capsule is a fibrous structure that surrounds the temporomandibular joint, providing stability and limiting excessive movement. The lower collagenous lamina is a thickened band within the TMJ capsule that helps restrict anterior movement of the condyle. Therefore, both structures work together to prevent the condyle from moving too far forward.Rate this question:

The disc of the TMJ is attached laterally and medially to the
- A.
Medial pterygoid
- B.
Lateral pterygoid
- C.
Poles of the condyle
- D.
Retrodiscal pad
- E.
None of the above
Correct Answer
C. Poles of the condyleExplanation
The disc of the TMJ is attached to the poles of the condyle. The poles of the condyle refer to the rounded ends of the mandibular condyle, which are located on both sides of the jaw joint. The attachment of the disc to the poles of the condyle allows for smooth movement and proper functioning of the temporomandibular joint. The other options, such as the medial and lateral pterygoid muscles and retrodiscal pad, are not directly involved in the attachment of the TMJ disc.Rate this question:

Pull the disc forward
- C.
Keep the disc from being pulled too far back
- D.
Keep disc from being pulled to far forward
- E.
None of the above
Correct Answer
D. Keep disc from being pulled to far forwardExplanation
The posterior collagenous lamina is a structure in the body that helps to prevent the disc from being pulled too far forward. This means that it acts as a barrier or support to limit the movement of the disc in the forward direction. It helps to maintain the proper alignment and positioning of the disc, preventing excessive movement that could lead to injury or damage.Rate this question:

The temporomandibular ligament is found in the
- A.
Posterior part of the capsule
- B.
Medial part fo the capsule
- C.
Anterior part fo the capsule
- D.
Lateral part of the capsule
Correct Answer
D. Lateral part of the capsuleExplanation
The temporomandibular ligament is found in the lateral part of the capsule. This ligament plays a crucial role in stabilizing the temporomandibular joint, which connects the jawbone to the skull. Its location in the lateral part of the capsule suggests that it helps to prevent excessive lateral movement of the jawbone, ensuring proper alignment and function of the joint.Rate this question:

Pain in the TMJ coming from other areas is known as ___________ pain.
- A.
Myofascial
- B.
Referred
- C.
False
- D.
None of the above
Correct Answer
B. ReferredExplanation
Referred pain is a phenomenon where pain is felt in a different location from its actual source. In the context of the question, if someone experiences pain in the temporomandibular joint (TMJ) that originates from other areas of the body, it is referred pain. This means that the source of the pain may be located elsewhere, but the individual feels the pain in their TMJ. Myofascial pain refers to pain that originates from the muscles and soft tissues, but it is not specifically related to pain felt in the TMJ. "False" and "none of the above" are not relevant to the concept of referred pain.Rate this question:

Dislocation of the TMJ is referred to as
- A.
Protraction
- B.
Retrusion
- C.
Subluxation
- D.
Depression
- E.
None of the above
Correct Answer
C. SubluxationExplanation
Subluxation refers to a partial dislocation of the temporomandibular joint (TMJ). It occurs when the condyle of the mandible slips forward and then returns to its normal position. This can cause pain, clicking or popping sounds, and difficulty in opening and closing the mouth. Subluxation is different from complete dislocation or luxation, where the condyle remains displaced and requires manual intervention to return it to its proper position. Therefore, subluxation is the correct term to describe the dislocation of the TMJ in this context.Rate this question:
