Which subcategory of connective tissue does cartilage belong to? Diagram the three subcategories of CT and their components.
Supporting Connective Tissue
Name the three types of cartilage.
Hyaline, elastic fibrous
True or False:
Cartilage obtains nutrients by diffusion since it doesn't have blood vessels.
True.
True or False:
Cartilage forms very quickly (forms template for many of the bones in our bodies).
True.
True or False:
Cartilage forms very early in development from mesenchymal areas.
True
There are two types of cells found in cartilage: chondroblasts and chondrocytes. Compare and contrast em.
Chondroblasts (chondro = cartilage ; blast = blast out something). Come from mesenchymal cells or multipotential CT cells. Differentiate to produce cartilage matrix: chondroitin sulfate fibers. Will eventually turn into a chondrocyte

- Chondrocyte (mature cartilage cell). Located within lacunae, tissue fluid (nutrients/ waste products). Euchromatic nucleus, nucleolus, Golgi complex, RER. Secretes tropocollagen, GAGs. May contain fat droplets.
[ Chondroblasts / chondrocytes ] are mature cartilage cells.
Chondrocytes. (Chondroblasts eventually turn into chondrocytes.)
Chondroblasts differentiate to produce cartilage matrix __________.
A. chondroitin sulfate fibers
B. hyaluronic acid
C. keratin fibers
A. chondroitin sulfate fibers
The ground substance of cartilage consists mainly of what proteoglycan?
chondroitin sulfate
Cartilage perichondrium consists of two layers: [ chondrogenic layer / fibrous layer ] is where dense, irregular connective tissue occurs and [ chondrogenic layer / fibrous layer ] is where chondroblasts are constantly differentiating and dividing.
Fibrous layer is the dense, irregular connective tissue ; chondrogenic layer is where chondroblasts are constantly differentiating and dividng
Cartilage growth can be appositional or interstitial. Describe each.
Appositional is "adding on" where chondroblasts divide, secret matrix. Interstitial is where chondrocytes divide producing isogenous groups (two or more cells within one lacunae).
Which type of cartilage is the most common type in the body?
Hyaline cartilage
Which type of cartilage consists mainly of Type II collagen fibers and chondroitin sulfate?
Hyaline cartilage
Which type of cartilage is distributed mainly in fetal skeleton, articular cartilage, nose, trachea, bronchi?
Hyaline cartilage
Which type of cartilage looks "glassy"? (hint: it's name)
Hyaline cartilage
Which type of cartilage has little ground substance, large chondrocytes, and typically contain large lipid droplets?
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
A. Elastic cartilage
Which type of cartilage is distributed mainly in the external ear, epiglottis, and part of the larynx?
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
A. Elastic cartilage
Which type of cartilage most closely resembles CT, functions as strengtheners at transitions, has minimal grounds substance, and has bundles of collagen type I fibers that fill its matrix?
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
B. Fibrocartilage
This cartilage type's chondrocytes may appear in parallel rows or randomly distributed.
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
B. Fibrocartilage
This cartilage types functions to provide stiffness and great tensile strength at tendon insertions.
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
B. Fibrocartilage
This cartilage is distributed at annulus fibrosus of intervertebral disc, pubic symphisis and attachment of some tendons to bones.
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline cartilage
B. Fibrocartilage
True or False:
Fibrocartilage is the only cartilage that does NOT have a perichondrium.
True
Put the following stages of cartilage calcification in order:
A. Calcium phosphate is deposited in matrix, restricting diffusion of nutrients.
B. Chondrocytes greatly hypertrophy
C. Chondrocytes secrete alkaline phosphatase (calcium magnet)
D. Chondrocytes die leaving behind calcified matrix
E. Bone is laid down upon the calcified matrix
B, C, A, D, E.
True or False:
Regarding cartilage calcification, calcified matrix turns into bone.
FALSE!! Bone is simply laid on top of the calcified matrix!
___________ in the fibrous layer of the perichondrium differentiate into ____________ in the chondrogenic layer. When it has surrounded itself with cartilage, it is then called a ________. A cluster of these cloned from a single one is called __________, representing interstitial growth of this tissue.

Fill with: chondroblast, chondrocyte, fibroblast, isogenous group, multipotential cell
MULTIPOTENTIAL CELLS in the fibrous layer of perichondrium ---> CHONDROBLASTS which, when surrounded by cartilage ---> CHONDROCYTE. then ISOGENOUS GROUP. digital histology Cartilage > Hyaline, 4 of 10
