📂በጣም ወሳኝ ባዮሎጂ የምስል ጥያቄ በኢንትራንስ ፈተና ሊመጣ የሚችል 👉Parts of the ear
1.Outer ear (external ear):
Outer ear is the part of your ear that’s visible and contains glands that secrete ear wax.
👉Its funnel-shaped canal leads to your eardrum, or tympanic membrane.
2.Middle ear: The middle ear contain three tiny bones in this area — the malleus, incus and stapes. They transfer sound vibrations to eardrum
👉The middle ears also contain eustachian tubes, which help equalize the air pressure .
3.Inner ear: The inner ear contains two main parts: the cochlea and the semicircular canals.
👉 Cochlea is the hearing organ. This snail-shaped structure contains two fluid-filled chambers lined with tiny hairs. When sound enters, the fluid inside of your cochlea causes tiny hairs to vibrate, sending electrical impulses to your brain.
👉The semicircular canals, also known as the labyrinthine, are responsible for balance.
