Answer:
outer ear
Explanation:
The ear can be divided into three different structures: 1-the outer ear, 2-the middle ear, and 3- the inner ear. The outer ear can be defined as the external part of the ear, which is composed of cartilage and skin. The outer ear consists of the auricle or 'pinna' (i.e., the cartilaginous portion of the ear), and the external auditory meatus (also known as the ear canal). The outer ear acts to direct sounds and vibrations into the ear canal to the tympanic membrane. Moreover, the middle ear is a cavity between the outer and inner ear that functions to transmit sound energy from the ear canal to the cochlea. Finally, the inner ear acts to convert acoustic energy into nerve impulses, which are transmitted to the central nervous system.
