☘Definition:-

• The ear is made up of three different sections that work together to collect sounds and send them to the brain: the outer ear, the middle ear, and the inner ear.

1️⃣ The Outer Ear: Collecting Sounds:-

• The outer ear is made up of the pinna — also called the auricle (say: OR-ih-kul) — and the ear canal. The pinna is the part of the ear you see on the side of your head. It's made of tough cartilage covered by skin. Its main job is to gather sounds and funnel them to the ear canal, which is the pathway that leads to the middle ear. Glands in the skin lining the ear canal make earwax, which protects the canal by cleaning out dirt and helping to prevent infections.

2️⃣ The Middle Ear: Good Vibrations:-

• The middle ear is an air-filled cavity that turns sound waves into vibrations and delivers them to the inner ear. The middle ear is separated from the outer ear by the eardrum, or tympanic (say: tim-PAN-ik) membrane, a thin piece of tissue stretched tight across the ear canal. Sounds hit the eardrum, making it move.

3️⃣ The Inner Ear: Nerve Signals Start Here:-

• The vibrations from the middle ear change into nerve signals in the inner ear. The inner ear includes the cochlea (say: KOH-klee-uh) and the semicircular canals. The snail-shaped cochlea changes the vibrations from the middle ear into nerve signals. These signals travel to the brain along the cochlear nerve, also known as the auditory nerve.
