Anatomy

The auriculotemporal nerve carries some fibers which are sensory to lining of tympanic cavity

Anatomy

The external (lateral) pterygoid muscle has two primary functions: it assists in depressing the mandible (opening the mouth) and in moving the mandible forward (protrusion). This dual function distinguishes it from other muscles of mastication, which primarily elevate the mandible.

Anatomy

Facial Artery:

1: True, it has cervical and facial portions.

2: True, it arises from the external carotid artery above the lingual artery.

3: True, it crosses the mandible at the anterior edge of the masseter muscle.

4: False, the cervical portion lies beneath the platysma, but the facial portion does not exactly lie "superficial in the carotid triangle"; rather, the facial artery travels more superficially than the cervical part in its course.

Anatomy

The parasympathetic fibers to pterygopalatine ganglion come from greater petrosal nerve

Anatomy

the foramen ovale and foramen rotundum are both openings in the sphenoid bone. The foramen ovale is located posterior and lateral to the foramen rotundum. The foramen rotundum transmits the maxillary nerve (V2), while the foramen ovale transmits the mandibular nerve (V3) and the accessory meningeal artery.

Anatomy

The mandibular 1st molar is supplied by Inferior alveolar nerve and long Buccal Nerve

Anatomy

Lateral pterygoid (paired action):

When both muscles contract together, they pull the condyles and articular discs forward → protrusion of the mandible.

This is important in opening the mouth beyond the initial hinge movement.

Unilateral contraction:

Produces side-to-side (lateral) movements of the mandible, useful in grinding food.

Elevation/Depression:

Elevation is mainly by masseter, temporalis, medial pterygoid.

Depression is mainly by suprahyoid muscles (digastric, geniohyoid, mylohyoid) and gravity.

Lateral pterygoid assists in depression only indirectly by pulling the condyle forward, but its primary function is protrusion.

Anatomy

Clavicle is the first bone to Ossify in the body

24467
Anatomy

The nerve to masseter passes posterior to temporomandibular joint

74505
Anatomy

It attaches superiorly at the medial border of the mandible and inferiorly at the body of the hyoid
