	* epibranchial placodes - give rise to the distal cells of the sensory ganglia of cranial nerves V, VII, IX and X.		* epibranchial placodes - (epipharyngeal placodes) give rise to the distal cells of the sensory ganglia of cranial nerves V, VII, IX and X.
			** geniculate placode - associated with the first pharyngeal cleft, generates the geniculate ganglion and distal parts of cranial nerve VII
			** petrosal placode - associated with the second pharyngeal cleft, generates the glossopharyngeal ganglion[disambiguation needed] and distal parts of cranial nerve IX
			** nodosal placode - associated with the third pharyngeal cleft, generates the nodose ganglion and distal parts of cranial nerve X

	motor - innervates the sternocleidomastoid and trapezius muscles		motor - innervates the sternocleidomastoid and trapezius muscles
			* sternomastoid - muscle superficial layer side of the neck, rotation of the head
			* trapezius - superficial muscles from occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula, move the scapulae and support the arm

Line 1:		Line 1:
			==Cranial Nerves==
			===CN I Olfactory===
			sensory - olfactory receptor neuron axons

			olfactory epithelium to cribriform plate of the ethmoid bone then to the olfactory bulb
			===CN II Optic===
			sensory - retinal ganglion neuron axons

			development - CNS out-pouching of the diencephalon (optic stalks)

			optic nerve fibres covered with myelin produced by oligodendrocytes

			ensheathed in all three meningeal layers (dura, arachnoid, and pia mater)
			===CN III Oculomotor===
			motor - innervates muscles that enable most eye movement

			development - oculomotor nerve is derived from the basal plate of the embryonic midbrain

			===CN IV Trochlear===
			motor - innervates the superior oblique muscle that enables eye movement


			===CN V Trigeminal===
			(semilunar ganglion or gasserian ganglion)

			three major branches - ophthalmic nerve (V1), maxillary nerve (V2), mandibular nerve (V3)

			mixed motor/sensory
			* sensory - provide tactile, proprioceptive, and nociceptive afference to the face and mouth.
			* motor - innervate the skin of the face via ophthalmic (V1), maxillary (V2) and mandibular (V3) divisions. Special visceral efferent (SVE) axons innervate the muscles of mastication via the mandibular (V3) division.

			===CN VI Abducent===

			motor - innervates the lateral rectus muscle that enables eye movement

			development - from the basal plate of the embryonic pons

			===CN VII Facial===
			mixed motor/sensory

			motor - innervates the muscles of facial expression

			sensory - taste from the anterior two-thirds of the tongue and oral cavity

			development - second pharyngeal arch
			* motor derived from the basal plate of the embryonic pons
			* sensory derived from cranial neural crest

			===CN VIII Acoustic===
			sensory - auditory and equilibrium

			development - otic placed

			===CN IX Glossopharyngeal===
			mixed motor/sensory

			lies anterior to the medulla oblongata

			Branchial motor (special visceral efferent) – supplies the stylopharyngeus muscle.

			Visceral motor (general visceral efferent) – provides parasympathetic innervation of the parotid gland via the otic ganglion.

			Visceral sensory (general visceral afferent) – carries visceral sensory information from the carotid sinus and carotid body.

			General sensory (general somatic afferent) – provides general sensory information from inner surface of the tympanic membrane, upper pharynx (GVA), and the posterior one-third of the tongue.

			Visceral afferent (special visceral afferent) – provides taste sensation from the posterior one-third of the tongue, including circumvallate papillae.

			===CN X Vagus===
			(pneumogastric nerve) responsible for heart rate, gastrointestinal peristalsis, sweating, and muscle movements in the mouth, including speech (via the recurrent laryngeal nerve)

			development
			* motor derived from the basal plate of the medulla oblongata
			* sensory derived from cranial neural crest

			===CN XI Accessory===
			motor - innervates the sternocleidomastoid and trapezius muscles

			===CN XII Hypoglossal===
			motor - hypoglossal nucleus of the ventromedial medulla oblongata from a number of smaller rootlets

			development - basal plate of the medulla oblongata
