Compositional parts and their functions . Pinna (ear flap) The ear flap or pinna is the outer portion of the ear. This is the physical portion of the ear that you see on the side of your head, which is used like a satellite dish to collect sound and transmit it inward where it can be translated into the appropriate medium. Meatus (ear canal) What Are the 3 Main Parts of an Ear? In the simplest terms, the ear can be categorized into three primary anatomical collections: the outer ear, the middle ear, and the inner ear: The Outer Ear is the curved part of the ear that is visible on the outside of the head. Its primary purpose is to collect sound waves, just like a satellite dish collects radio waves. The ear can be divided into three parts: The external ear includes the pinna (outer, visible ear) and the ear canal; The middle ear includes the tympanic membrane (ear drum) and the ossicles (middle ear bones) The inner ear, which includes the cochlea (organ of hearing) and vestibule (organ of balance)
The structure of the auditory canal has two parts. a) The outer one-third of the canal is made up of cartilage. It has skin with hair follicles. Cerumen and pilosebaceous glands are also seen in this part and are a seat for Staphylococcus bacterial infections too. b) The inner two-thirds of the canal is made of bone. Parts of the Outer Ear The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3]. The tympanic membrane is a very thin structure that separates the outer ear canal from the middle ear space. Eye Parts. Description and Functions. Cornea. The cornea is the outer covering of the eye.
