Examples Figure 2: Elastic cartilage tissue with large chondrocytes and elastic fibers stained pink in the matrix. Elastic cartilage is found in the epiglottis (part of the larynx) and the pinnae (the external ear flaps of many mammals, including humans). Cartilage is classified in three types: 1) elastic cartilage, 2) hyaline cartilage, and 3) fibrocartilage, which differ in the relative amounts of these three main components. Multiple Select Question Select all that apply Indicate which of the following are examples of locations of elastic cartilage. Elastic and hyaline cartilage have similar appearances when stained by H&E because elastic fibers are unstained. Your larynx is a hollow tube that helps move air from your nose and mouth to your lungs. Larynx The larynx is the organ responsible for speech and airway protection. The epiglottis is a flap-like structure located at the entrance of the larynx that plays a crucial role in the respiratory and digestive systems. Its flexibility is crucial for speech and breathing functions. From: Core Anatomy - Illustrated [2019], Musculoskeletal and Sports Medicine For The Feb 11, 2025 · Elastic cartilage's unique properties, due to its high elastin content, make it suitable for locations requiring flexibility and resilience, such as the epiglottis, parts of the larynx, external ear, and auditory tube. Learn why cartilage is vital for movement, joint health, and body support. Study with Quizlet and memorize flashcards containing terms like CARTILAGE, CARTILAGE FUNCTION 1, CARTILAGE FUNCTION 2 and more. Its main function is to prevent food and liquids from entering the trachea, ensuring safe passage into the esophagus. It is more flexible than hyaline cartilage but provides less support than fibrocartilage. The three different types of cartilage tissue are elastic, hyalin, and fibrous. Perichondrium Location In adults, perichondrium: covers hyaline cartilage in the larynx (voice box), trachea (windpipe), nose 11 and ribs (costal cartilage 2), and elastic cartilage in the external ear (auricular cartilage), epiglottis and Start studying Elastic Cartilage. This prevents Feb 8, 2025 · The laryngeal cartilages form an intricate structural framework that is essential for voice production, airway protection, and breathing. Cartilage, a connective tissue, is secreted by chondrocytes and composed of collagen and elastin, providing strength and flexibility. Select one or more: a. This type of cartilage provides support and flexibility and is present at the ends of long bones. During swallowing, the epiglottis swings downward to cover the opening of the trachea, thereby preventing food and beverages from entering the respiratory tract. During swallowing, the epiglottis folds inferiorly to block the entrance to the trachea and bronchi, preventing food and liquid from entering the air passages. Some common locations include: The external ear (also known as the auricle or pinna) The epiglottis, which is part of the larynx and helps prevent food from entering the windpipe during swallowing The Eustachian tube, which connects the middle ear to the back of the throat These areas benefit from the The larynx is composed of an elastic cartilage that is lined by a stratified squamous epithelium with collections of lymphoid tissue scattered throughout the lamina propria. Jan 17, 2018 · Elastic cartilage is found in the ear and epiglottis (located in the throat) as well as parts of the nose and trachea. The type of Oct 9, 2023 · The Epiglottis, a flexible piece of elastic cartilage, is the 'guardian of the airways'. Oct 30, 2023 · The larynx is composed of three large unpaired cartilages (cricoid, thyroid, and epiglottis) and three paired smaller cartilages (arytenoid, corniculate, and cuneiform), making a total of nine individual cartilages. fsjof hywbm scxceoh kklco uquss ejopl cgser cxglhkhr gwv hazj
