Q

Optic Nerve (II)

A

Extension of brain carrying afferent fibers

Oculomotor Nerve (III)

Superior divisions: levator palpeerde superioris, superior rectus Inferior division: medial rectus, inf. rectus, inf. oblique

Trochlear nerve (IV)

arises from post. midbrain enters orbit thru supraorbital fissure

Abducent Nerve

arises from brainstem between pons & medulla enters orbit thru supraorbital fissure

Ophthalmic Nerve (CN V1)

first branch of trigeminal nerve

Nasociliary Nerve (V1)

branch off ophthalmic nerve (V1) through supraorbital fissure in common tendinous ring

Frontal nerve (V1)

branch off ophthalmic nerve (V1) via supraorbital fissure above tendinous ring

Lacrimal Nerve (V1)

branch off ophthalmic nerve (V1) via supraorbital fissure above tendinous ring

Facial Nerve (VII)

Exits thru stylomastoid foramen motor to mm of facial expression

Temporal Nerve Zygomatic n Buccal n Mandibular n Cervical n Post. auricular n Digastric branch n

branches of Facial Nerve (VII)

Maxillary Nerve (V2)

branch of trigeminal nerve exits thru rotundum

Mandibular (V3)

branch of trigeminal nerve exits thru foramen oval

Facial artery

branch of external carotid upper/lower lip, side of nose, medial eye

Maxillary artery

branch of external carotid medial cheek, upper lip, wall of mouth, chin

Transverse Facial Artery

branch from superficial temporal, terminal branch of external carotid artery lateral cheek

Ophthalmic Artery

branch of internal carotid exits cranium thru supraorbital fissure

Mandibular Nerve (V3)

branch of trigeminal nerve

Main Stem (V3)

Mandibular nerve branch - meningeal branch - nerve to medial pterygoid

Anterior Trunk (V3)

Mandibular nerve branch Buccal- sensory cheek masserteric- motor deep temporal- motor nerve to lat. pterygoid

Posterior Trunk (V3)

Mandibular nerve branch Auriculotemporal Lingual Inferior alveolar - nerve to mylohyoid - incisive -mental

Maxillary Artery

Largest branch external carotid artery

Maxillary Nerve

Enters thru foramen rotundum 4 divisions: 1. ganglion 2. zygomatic 3. post. alveolar 4. infra-orbital

Hypoglossal nerve (XII)

enters thru hypoglossal canal innervates all intrinsic tongue muscles
