Question | Answer |
---|---|
name the three types of cartilage | hyalin, Elastic, fibrous |
what is the most common type of cartilage? | hyaline |
this is a group of chondrocytes that come from the same parent group | isogenous group |
where is Hyaline cartilage located? | trachea, bronchi, larynx, nose..etc. |
this disease occurs due to the thinning of cartilage between the bones and the cartilage starts to proliferate and the tissue can't hold itself together | osteoarthritis |
this is an autoimmune disease of joints which tends to be bilateral. extra cells go to the joint capsule and it becomes thicker. the joint surfaces then start to rub together. | Rheumatoid Arthritis |
if cartilage is avascular, where do the nutrients come from? | the perichondrium |
Elastic cartilage is located here | Eustachian tube, External ear, and Epiglottis |
this condition is due to repeated trauma causing hematomas between the perichondrium and cartilage, preventing nutrition, resulting in the underlying cartilage being replaced by dense irregular CT. common in wrestlers | cauliflower ear (Auricular Hematoma) |
this type of cartilage is made of hyaline matrix and dense regular connective tissue and has no perichondrium. | fibrocartilage |
this type of cartilage growth occurs between the cells | interstitial growth |
this type of cartilage growth occurs when the entire cartilage gets bigger | Appositional Growth |
if cartilage is avascular, how does repair and growth take ploace? | via the Perichondrium |
this type of growth occurs when mesenchyme turns directly to bone and occurs mostly in the skull | intramembranous ossification |
this type of growth occurs when mesenchyme first turns to cartilage, and then to bone | endochondral ossification |
list the five zones of the growth plate for endochondral ossification | reserve cartilage, proliferation, hypertrophy, calcified cartilage, resorption/osteogenesis. |
in this disease, the zone of proliferation does not occur during endochondral ossifricaiton | Achondroplasia |
