The nasopalatine nerve innervates the anterior hard palate and exits through which foramen?
Answer: Incisive foramen
The nasopalatine nerve exits through the incisive foramen, located in the midline of the anterior hard palate just posterior to the maxillary central incisors.
The greater palatine nerve exits through the greater palatine foramen and primarily innervates which area?
Answer: The posterior hard palate and adjacent palatal gingiva
The greater palatine nerve exits the greater palatine foramen (medial to the maxillary third molar) and innervates the posterior hard palate and adjacent palatal gingiva from the canine area posteriorly.
Which cranial nerve provides motor innervation to all intrinsic and most extrinsic muscles of the tongue?
Answer: Hypoglossal nerve (CN XII)
The hypoglossal nerve (CN XII) provides motor innervation to all intrinsic tongue muscles and most extrinsic tongue muscles, controlling tongue movement.
The temporomandibular joint (TMJ) is classified as which type of synovial joint?
Answer: Ginglymoarthrodial (combined hinge and gliding) joint
The TMJ is a ginglymoarthrodial joint capable of both rotational (hinge) movement in the lower joint space and translational (gliding) movement in the upper joint space, separated by the articular disc.
Which muscle of mastication acts as the primary depressor of the mandible (jaw opener) when contracting bilaterally?
Answer: Lateral pterygoid
The inferior head of the lateral pterygoid muscle pulls the condyle and disc forward (translation) during opening, making it the primary muscle of mastication that opens the jaw.
The pterygomandibular raphe serves as an attachment point for which two muscles?
Answer: Buccinator and superior pharyngeal constrictor
The pterygomandibular raphe is a fibrous band that serves as the attachment for the buccinator muscle anteriorly and the superior pharyngeal constrictor muscle posteriorly.
Which cervical lymph node, sometimes called the 'tonsillar node,' is a key landmark palpated during the extraoral lymph node examination?
Answer: Jugulodigastric node
The jugulodigastric (tonsillar) node is located near the angle of the mandible at the intersection of the posterior digastric muscle and the internal jugular vein, and is a key node palpated during cervical examination.
