|
matrix
|
|
What are the three types of cartilage?
|
hyaline, elastic, and fibrocartilages.
|
|
Where can hyaline cartilage be found?
|
at end of the nose and weaar surfaces of joints
|
|
Where can elastic cartilage be found?
|
External ear
|
|
Where can fibrocartilages be found?
|
In between vertebrae
|
|
___________ are cartilage cells.
|
Chondrocytes
|
|
___________ are living bone cells.
|
Osteocytes
|
|
Found in the bone, Haversian canels are made up of ___________ and ___________.
|
blood vessels and nerves
|
|
In bone, ______________ connects Haversian canals.
|
volkman canal
|
|
In bone, ___________ transport 02, nutriets from Haversian canal to lacuna.
|
canoculi
|
|
In bone, matrix is made up of salts ______ and _______-.
|
Calcium, Phosphorous
|
|
Why does cartilage heal slow?
|
Poor blood supply
|
|
_____________ is known as growth hormone.
|
Somatotropin
|
|
How does cartilage grow? (4 steps)
|
Brain releases somatotropin. Somatotropin stimulates chrondocytes to produce matrix. New matrix is deposited under perichondrium. Cartilage gets larger.
|
|
Growth zones in the bone are called _________ ___________-.
|
epiphyseal plates
|
|
How does bone grow? (3 steps)
|
Brain release somatotropin. Somatotropin stimulates epiphyseal plate to deposit new matrix on either side. Length of bone increases.
|
|
As soon as ____ _____________ kick in growth plates disappear.
|
sex hormones
|
|
How does the bone grow in diameter? (3 steps)
|
Brain releases somtotropin. Somatotropin stimulates osteocytes under periosteum to produce matrix which is deposited under the periosteum.Somatotropin stimulates osteoclasts lining marrow cavity to remove matrix to allow marrow cavity to increase in diameter.
|
|
Name the six major types of joints.
|
Hinge, ball & socket, immovable joint, partially movable, gliding, and pivotal.
|
|
Where can hinge joints be found?
|
fingers, elbows, knees, mandible
|
|
Where can ball and socket joints be found?
|
humerus and scapula, femure and pelvis
|
|
Where cn immovable joints be found?
|
bones of the skull; male pelvis bone
