What type of cartilage is the epiglottis made of?
Elastic cartilage
Elastic cartilage forms the core of the epiglottis: Perichondrium – a layer of dense irregular connective tissue that surrounds cartilage.
What is elastic cartilage made up of?
elastic fibers
Cartilage is made up of specialised cartilage cells called chondrocytes. In elastic cartilage, they are organised into elastic fibers, which make up a threadlike network or matrix. This matrix is composed of glycosaminoglycans, proteoglycans and multiadhesive glycoproteins.
Why epiglottis is made up of elastic cartilage?
In order to prevent food from entering the air passages of the human larynx and trachea, a thin, leaf-shaped flap of tissue, the epiglottis, closes the opening into the larynx during swallowing. At the core of the epiglottis is a thick elastic collagen support. …
Why is the epiglottis made of elastic cartilage?
The epiglottis is made of elastic cartilage covered with a mucous membrane, attached to the entrance of the larynx. It projects upwards and backwards behind the tongue and the hyoid bone….

Why is epiglottis elastic cartilage?
Is elastic cartilage Basophilic?
Note that the cartilage matrix is relatively homogeneous and basophilic. This is due to the masking of the collagen fibers by the high concentration of the glycosaminoglycans in the ground substance. The matrix immediately surrounding the lacunae is more intensely basophilic. This zone is the territorial matrix.
Does fibrocartilage have elastic fibers?
Fibrocartilage. Fibrous cartilage has lots of collagen fibers (Type I and Type II), and it tends to grade into dense tendon and ligament tissue. It owes its flexibility and toughness to the fibrous tissue, and its elasticity to the cartilaginous tissue.
What type of tissue is fibrocartilage?
Fibrocartilage is a specialized form of connective tissue in which the ground substance is cartilage. The fibrous and cartilaginous components render this tissue extremely tough and resilient. The cell types found in this connective tissue include both fibroblasts/cytes and chondroblasts/cytes.
What type of tissue makes up the epiglottis quizlet?
What type of tissue makes up the epiglottis? The epiglottis is part of the larynx. It is composed of elastic cartilage.
What is fibrocartilage cartilage?
In cartilage. Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
Is elastic cartilage Acidophilic?
Chondrocytes are situated in lacunae and no identifiable perichondrium is present. The matrix is acidophilic because of the large amount of coarse type I collagen fibers .
Is the epiglottis made of elastic cartilage?
Composed mostly of elastic cartilage, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.
Where does the epiglottis attach to the throat?
The epiglottis is a flap of elastic cartilage that sits beneath the tongue at the back of the throat. Its main function is to close over the windpipe (trachea) while you’re eating, to prevent food entering your airways. The epiglottis stalk attaches anteriorly to the internal aspect of the angle of the thyroid cartilage (Figure 1).
Who was the first person to write the epiglottis?
The epiglottis was noted by Aristotle, although the epiglottis’ function was first defined by Vesalius in 1543.
What kind of cartilage is in the middle ear?
Epiglottis Elastic Cartilage. Composed mostly of elastic cartilage, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.
