The term 'PART OF EAR' can be solved by the four-letter word 'LOBE'. The ear is composed of three main parts: the outer ear, the middle ear, and the inner ear. The outer ear consists of the pinna, which is the visible part of the ear, and the ear canal. The middle ear contains the eardrum and three tiny bones called ossicles. The inner ear is made up of the cochlea, which is responsible for hearing, and the vestibular system, which helps with balance. The LOBE is the fleshy lower part of the outer ear.
