Which skeleton is made of cartilage instead of bone?
The human skeleton is made up of 206 bones, which are connected by joints and ligaments. However, there is one part of the human body that has a skeleton made of cartilage instead of bone: the ear.
The ear is divided into three parts: the outer ear, the middle ear, and the inner ear. The outer ear is made up of skin and cartilage, and it is responsible for collecting sound waves and directing them into the ear canal. The middle ear is located behind the eardrum, and it contains three small bones called the ossicles. The ossicles vibrate when sound waves hit the eardrum, and they transmit these vibrations to the inner ear. The inner ear is located deep within the skull, and it contains the cochlea, which is a spiral-shaped organ that converts sound vibrations into electrical signals that are sent to the brain.
The cartilage in the ear is called hyaline cartilage. Hyaline cartilage is a smooth, flexible type of cartilage that is also found in the nose, trachea, and bronchial tubes. It is strong enough to support the ear, but it is also flexible enough to allow the ear to move.
