The sensory organ that involved in the mechanism of sight

• ear

• eye

• skin

• nose

• tongue

The largest sensory organ

• eye

• tongue

• ear

• skin

• nose

The type of taste

Other sense that is closely related to sense of the smell is the

• sense of hearing

• sense of taste

• sense of touch

Retina of the eye contains two types of photoreceptors, which are

• rod cells and cone cells

• rod cells and square cells

• triangle cells and cone cells

• circle cells and square cells

Mechanism of sight

• light-->lens-->brain-> retina

• light-->retina-->brain-->lens

• light-->brain-->retina-->lens

• light-->lens-->retina--> brain

Mechanism of hearing

• sound-->ear drum-->ossicles--> cochlea-->brain

• sound-->ossicles-->ear drum--> cochlea-->brain

• sound-->brain-->ossicles--> cochlea-->ear drum

• sound-->ear drum--> cochlea-->ossicle-->brain

The older person is weaker their ability of hearing because

• aging

• range of hearing become larger

• ear drum become more elastic

• ear drum less elastic
