Head Anatomy

Skull Bones I

100

The two parts of the cranium

What are the neurocranium and the viscerocranium

200

Suture that separates the parietal and occipital bones

What is the lambdoid suture

300

One of the thinnest portions of the skull located at the junction of the temporal, parietal, occipital, and sphenoid bones

What is the Pterion

400

The joint where the condylar process of the mandible articulates with the temporal bone

What is the TMJ

500

This bone sits on top of the palatine bone when looking inferiorly and extends backwards.  It also separates the posterior nasal apertures/choanae.

What is the vomer

Skull Bones II

100

The foramen where the spinal cord enters the skull

What is the foramen magnum

200

The suture that separates the two parietal bones

What is the sagittal suture

300

Part of the sphenoid bone seen on the lateral view of the skull

What is the greater wing

400

The process of the temporal bone located just posterior to the auricle

What is the mastoid process

500

This area of the ethmoid bone is where small branches of the olfactory nerve penetrate through to the nose

What is the cribiform plate

Facial Muscles

100

Muscle that allows you to press your cheek against your teeth

What is the buccinator

200

Muscle that elevates and protrudes the lower lip

What is the mentalis

300

Muscle that helps depress the mandible and tenses skin of the inferior face and neck

What is the platysma

400

Muscle that deepens the furrow between the nose and corner of the mouth during sadness

Levator labii superioris possibly the levator anguli oris

500

Muscle that draws down the medial angle of the eyebrows producing transverse wrinkles over the bridge of the nose

What is the procerus

Muscles of Mastication

100

Function of the muscles of mastication

What is helping move the mandible during chewing and talking

200

Muscle that closes the jaw and is fan shaped

What is the Temporalis

300

Muscle that opens and protrudes the jaw as well as allowing side to side grinding action

What is the lateral pterygoid

400

Flat, thick muscle that closes the jaw

What is the masseter

500

Muscle that parallels the masseter and closes the jaw

What is the medial pterygoid

Innervation

100

Main function of the facial nerve

What is motor innervation to the muscles of facial expression

200

Two main functions of the trigeminal nerve

What is sensory innervation of the face and motor innervation of the muscles of mastication

300

This branch of the trigeminal nerve provides sensory and motor innervation

What is the mandibular branch

400

This branch of the trigeminal nerve provides sensory innervation over the bridge of the nose

What is the ophthalmic branch

500

This branch of the facial nerve provides motor innervation to the intra-orbital, lateral nasal , and the upper lip areas

What is the zygomatic branch
