What cartilages in the lid for the larynx?
The laryngeal lid, or epiglottis, is primarily composed of elastic cartilage. This flexible cartilage allows the epiglottis to fold over the larynx during swallowing, preventing food and liquids from entering the airway. Additionally, the larynx itself contains other types of cartilage, including hyaline cartilage in structures like the thyroid, cricoid, and arytenoid cartilages, which provide support and shape to the laryngeal framework.
What are the three kinds of skeletal cartilage?
The three types of skeletal cartilage are hyaline cartilage, elastic cartilage, and fibrocartilage. Hyaline cartilage is the most abundant type and provides support with flexibility. Elastic cartilage contains elastic fibers, allowing for greater flexibility. Fibrocartilage is the strongest type, providing both support and cushioning.
What type of cartilage forms the epiglottis?
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.
Is the ear made of fibrocartilage?
No, the ear is primarily composed of elastic cartilage, which is different from fibrocartilage. Elastic cartilage is flexible and allows the ear to maintain its shape while also being able to bend and move. Fibrocartilage is found in structures that require both support and mobility, such as intervertebral discs.

What connective tissues form framework of outer ear?
The outer ear is primarily composed of elastic cartilage and fibrocartilage. Elastic cartilage forms the pinna of the ear, while fibrocartilage is found in the external auditory canal. These connective tissues provide structural support and flexibility to the outer ear.
Does elastic cartilage form tendons?
No, elastic cartilage does not form tendons. Tendons are primarily composed of dense regular connective tissue, specifically collagen fibers, that attach muscles to bones and provide support for movement. Elastic cartilage, on the other hand, is a type of cartilage that is more flexible and elastic, found in structures like the ear and epiglottis.
Supports the external ear?
The external ear is supported by the elastic cartilage of the auricle (pinna). This cartilage helps maintain the shape and structure of the external ear, allowing it to collect and direct sound waves into the ear canal towards the eardrum. The external ear also contains the earlobe, which is primarily composed of fat and connective tissue.
Where is elastic cartilage found?
Elastic Cartilage is found on the external ears and larynx.

The cartilage that provides support for the larynx and external ear?
elastic cartilage supports the external ear
What type of cartilage forms the epiglottis?
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.
What supports the external ear?
The external ear is supported by elastic cartilage, particularly the auricle (pinna) which is the visible part of the external ear. This cartilage provides structure and shape to the ear while allowing for flexibility and movement.
What is the laryngeal cartilage that keeps swallowed materials out of the lower respiratory system?
epiglottis
