|
effect of GH on bone
|
stimulates formation of somatomedin in liver - which stimulates growth of cartilage in the epiphyseal plate
|
|
|
effect of thyroid hormone on bone
|
stimulates bone growth
|
|
|
effect of calcitonin on bone growth
|
inhibits osteoclast activity - promotes bone growth
|
|
|
what are the three structural classifications of joints
|
fibrous
cartilaginous synovial |
|
|
fibrous joint
|
structural classification of joint
-bones held together by dense regular (fibrous) CT -immovable -three types (gomphoses, sutures, syndesmoses) |
|
|
cartilaginous joint
|
structural classificatio of a joint
-where bones are joined by cartilage |
|
|
synovial joint
|
structural classification of a joint
- where the joint is filled with fluid, bones are enclosed in a capsule, and are joined by ligaments -freely movemable -diarthroses -joint cavity |
|
|
what are the three functional classifications of joints
|
synarthrosis
amphiarthrosis diarthrosis |
|
|
gomphosis
|
type of fibrous joint
- between teeth and jaw bone |
|
|
suture
|
type of fibrous joint
- bone to bone - suture |
|
|
syndesmosis
|
type of fibrous joint
- bones are joined by ligaments only like fibula/tibia, radius/ulna -allow for slight movement - amphiarthroses |
|
|
synarthrosis
|
immovable
|
|
|
amphiarthrosis
|
slightly moveable
|
|
|
diarthrosis
|
freely movable
|
|
|
cartilaginous joints
|
type of structural classification of a joint
- bones attached by cartilage -no joint cavity -can be two types: synchondroses or symphyses |
|
|
synchondroses
|
type of cartilaginous joint
-cartilage and bone like where hyaline cartilage wraps around the head of the femur. |
|
|
symphyses
|
type of cartilaginous joint
- cartilage joins bones together like pubic symphysis and intervertebral discs -amphiarthroses |
|
|
synovial joint accessory structures
|
bursae, fatpads, tendons
|
|
|
bursae
|
fibrous, saclike structure that contains synovial fluid and is lined by synovial membrane
found in synovial joints |
|
|
fatpads
|
often distributed along the periphery of a synovial joint
act as packing material and provide some protection for the joint fill the spaces that form when bones move and the joint cavity changes shape |
|
|
what are the different synovial joints
|
planar (gliding)
hinge pivot condyloid (ellipsoid) saddle joints ball and socket |
|
|
example of pivot joint
|
atlas on the dens of axis
|
|
|
example of hinge joint
|
elbow
|
|
|
example of a saddle joint
|
tarsal and MT
|
|
|
example of a condyloid joint
|
MT and phalanges
|
|
|
example of a planar joint
|
tarsal tarsal
|
|
|
gout
|
arthritis caused by metabolism.. unable to break down uric acid and it builds up in the joints as crystals
|
|
|
osteoarthritis
|
arthritis caused by wear and tear
|
|
|
rheumatoid arthritis
|
genetic - born with it, can be very debilitating
|
