Answer 1

Ans5:- 3) saccule.

Saccule and Utricle

The saccule and utricle are referred to collectively as "the otolith organs". They sense linear acceleration and are affected by gravity. They also provide you with information concerning changes in head position (tilt). Because of the way they are situated within the vestibular apparatus, the saccule is more sensitive to vertical acceleration (like riding in an elevator) and the utricle is more sensitive to horizontal acceleration (riding in a car).

The semicircular canals allow us to sense the direction and speed of angular acceleration. The semicircular canals are oriented along three planes of movement with each plane at right angles to the other two.

Spiral organs are organ of choclia.

Ans6:- FACIAL NERVE.

Sensory afferents within three cranial nerves innervate the taste buds

The sensory fibers that innervate the taste buds travel in cranial nerves VII, IX and X. The chorda tympani carries fibers from VII to innervate taste buds on the anterior portion of the tongue, within the fungiform papillae and the anterior portion of the foliate papillae. Buds within the circumvallate papillae and the posterior portion of the foliate papillae are innervated by the lingual branch of the glossopharyngeal nerve (IX). Taste buds of the epiglottis and the esophagus are innervated by the superior laryngeal branch of the vagus (X).
