|---|---|---|---|---|---|
| Skeletal Cartilage | made up of some variety of cartilage tissue, which consists primarily of water
🗑
|
||||
| cartilage tissue | consists mostly of water, accounting for its resilience, that is the ability to spring back to its original shape after being compressed
🗑
|
||||
| perichondrium | The cartilage which contains no nerves, or blood vessels, is surrounded by a layer of dense irregular connective tissue, the ________
🗑
|
||||
| perichondrium | "around the cartilage" acts like a girdle to resist outward expansion when the cartilage is compressed. Contains the blood vessels from which nutrients diffuse through the matrix to reach the cartilage cells.
🗑
|
||||
| three types of cartilage tissues: | Hyaline cartilages, elastic cartilages, fibrocartilages
🗑
|
||||
| chondrocytes | basic components of cartilage tissues
🗑
|
||||
| chondrocytes | encased in small cavities (lacunea) within an extracellular matrix containing a jelly like substance and fibers
🗑
|
||||
| Hyaline Cartilages | look like frosted glass when freshly exposed, provides support within flexability and resilience.
🗑
|
||||
| Hyaline Cartilages | Most abundant skeletal cartilages
🗑
|
||||
| Skeletal Hyaline Cartilages include | articular cartilages, costal cartilages, respiratory cartilages, nasal cartilages
🗑
|
||||
| articular cartilages | covers the ends of most bones and movable joints
🗑
|
||||
| costal cartilages | connect the ribs to the sternum (breastbone)
🗑
|
||||
| respiratory cartilages | form the skeleton of the larynx (voicebox) and reinforce other respiratory passages
🗑
|
||||
| nasal cartilages | support the external nose
🗑
|
||||
| Elastic Cartilages | looks very much like hyaline cartilages, but they contain more stretchy elastic fibers and are better to stand up to handle repeated bending.
🗑
|
||||
| Elastic Cartilages | type of cartilage in the external ear and the epiglottis (the flap that bends to open the larynx each time we swallow
🗑
|
||||
| Fibrocartilage | highly compressable and have great tensile strength
🗑
|
||||
| Fibrocartilage | The perfect intermediate between hyaline and elastic cartilages, ________ consist of rughly parrallel rows of condrocytes aternating with thick collagen fibers.
🗑
|
||||
| Fibrocartilage | occur in that are subjected to both heavy pressure and stretch, such as pad like cartilages (menisci) of the knee and the discs between the vertibrae
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
