Question

discussing each of the five senses, the cranial nerve(s) responsible for them as well as where the cranial nerves originate and terminate.

Answer 1

Sense organ	function	cranial nerve	origin of cranial nerve	termination of cranial nerve
nose	sensory in action - helps in the odor molecules sensation through olfactory epithelium located at the back of the nasal cavity	olfactory nerve cranial nerve I	olfactory lobe	olfactory epithelium of nasal chamber
eye	sensory in action - help in the vision with the help of the retina, rods, and cons based on the photon incident on it.	optic nerve cranial nerve II	superior colliculi of the midbrain and pretectal nucleus of the brain stem and also in the suprachiasmatic nucleus of the hypothalamus	the retina of the eye - which seen on the back of the eyeball
Skin, tongue, and eyes		Trigeminal nerve cranial nerve V	From the side medulla oblongata
	supplies lacrimal glands, conjunctiva of the eye, skin of forehead, eyelids, etc.	a) Ophthalmic i) Lacrimal nerve ii) Frontal nerve iii) Nasociliary nerve	lateral aspect of the radix motoria	i) Lacrimal gland ii) dorsal margin of the orbit - skin, and conjunctiva of the upper eyelid, the nasal canthus, and the forehead iii) medial aspect of orbit and divide into the ethmoidal nerve to the ethmoidal foramen and infratrochlear nerve. Supplies iris, bulbar conjunctiva, ciliary muscle and cornea
	cheeks, upper gums, upper teeth, and lower eyelids	b) Maxillary	lateral aspect of the radix motoria	supply lacrimal, nasal and palatine glands
	Teeth and gums of the lower jaw, pinna o the ear, lower lip and tongue	c) Mandibular	lateral aspect of the radix motoria
Ear and tongue	Helps in the taste perception, facial expression and also supply the skin of the pinna	Facial nerve cranial nerve VII	two separate nuclei on the medulla oblongata. The sensory fibres from geniculate ganglionsensory innervation to buccal cavity, tongue, mandibular teeth , the lower lip and parts of the facial skin	terminate by dividing into buccal branches to motor muscles of cheek, lips and names. The first branch of it supplies skin on the back of the external ear
Ear	helping in hearing and maintenance of body balance	Vestibulocochlear nerve cranial nerve VIII	ventral and dorsal nuclei of cochlear nuclei on the medulla oblongata	vestibular apparatus of the inner ear
tongue	help in the taste perception, movement of the pharynx and in the secretion of saliva	glossopharyngeal nerve cranial nerve IX	ventrolateral aspect of the medulla oblongata	terminate by dividing into pharyngeal and lingual nerve thus pharyngeal nerve become pharyngeal plexus which join to vagus and lingual nerve terminate in the caudal third part of the tongue
ear	supplying the inner side of the pinna of the ear	cranial part of the vagus nerve cranial nerve X	ventrolateral aspect of the medulla oblongata in between glossopharyngeal and accessory nerve	innervates skin inside the external ear
