Anatomy

The occipital artery does not supply the lower third of the sternocleidomastoid (SCM) muscle:<br> 
Upper third: Supplied by the occipital artery <br>
Middle third: Supplied by the superior thyroid artery and the external carotid artery <br>
Lower third: Supplied by the suprascapular artery, the transverse cervical artery, the thyrocervical trunk, and the superficial cervical artery<br>

Anatomy

The trigeminal ganglion lies on Anterior surface of petrous temporal bone near its apex in Meckel’s cave which is a space of dura mater

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

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

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.
