The epiglottis is made up of elastic cartilage, which is a type of cartilage containing elastic fibers that provides flexibility and support. This type of cartilage is present in structures that require both strength and the ability to bend.
The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
hyaline cartilage
We call cartilage that is high in fiber fibrous cartilage. Fibrous cartilage is found in the intervertebral discs and pubic symphysis.
The tip of the nose is connected by the nasal cartilage, which is a type of hyaline cartilage. It gives the nose its shape and structure while allowing for some flexibility and movement.
