10b. Skeletal system Flashcards
What decreases friction in a joint and increases mobility
synovial fluid
What joint absorbs shock and provides some movement?
cartilaginous
What is the function of ligaments?
join bones to bones and stabilise joints
What is the structure of a fibrous joint
fixed joint between between bones
The knee is an example of what type of synovial joint?
Hinge
What prevents friction between bones, muscles, tendons and ligaments.
bursa
osteocytes
connect and communicate between osteoblasts and clasts
chondr
cartilage
What is the function of the joint capsule?
To help stabilise the joint
cost
rib
arthr
joint
What is the root term for joint?
arthr
pelv
pelvic/hip bone
What is at the end of the bone and decreases friction and absorbs shock to increase mobility of joint
articular cartilage
What is function of a cartilaginous joint?
To allow for some movement and absorb shock
What synovial joints allows flexion, extension, adduction, abduction and circumduction ?
saddle, ball and socket and condyloid joints
What is the root term for bone?
oste
What type of joint is found in the elbow?
Synovial
What type of bone tissue is less dense, internal, trabeculae/rod like structures
cancellous bone
What is the function of bursa?
To prevent friction between bones, muscles, tendons and ligaments.
Give an example of a hinge joint
elbow
knee
phalanges
osteogenisis
Production of bone
What is the cavity to help stabilise the joint
joint capsule
What is the root term for bone marrow?
myel
Give an example of sliding/plane joints
carpals, tarsals
What are the functions of the skeletal system?
To protect organs and provide structure
To assiste in productio of movement
To provide a Boundary
To produce RBC
To store minerals
The carpals are exmaples of what type of joint?
gliding/plane
What is the function of the articular cartilage?
to decrease friction and absorb shock to increase mobility of joint
What is the root term for rib?
cost
What synovial joint allows flexion, extension, adduction and abduction = circumduction with the greatest range of movement?
ball and socket joint
