Skeletal System Flashcards
(25 cards)
What is a long bone
A long straight bone that allows for gross movements
What is a short bone
A small bone that allows for fine controlled movements
What is a flat bone
A large bone that usually protects organs
What is an irregular bone
Specifically shaped bone to protect parts of the body
What is a synovial joint
A freely movable joint that is specially designed to prevent injury and allow movement
What are the 6 parts of a synovial joint
Synovial fluid, bursae, synovial membrane, ligament, tendon, cartilage
What is synovial fluid and where is it produced
It lubricates joints to reduce friction and is produced in the synovial membrane
What is the function cartilage
Absorbs shocks and covers the bone with h prevents them from rubbing together
What is the bursae
Fluid filled bag that prevents friction
What is the synovial membrane
The lining of the joint that produces synovial fluid
What does a ligament attach
Attached bone to bone
What does a tendon attach
Attaches muscle to bone
What are the 2 types of synovial joints
Hinge, ball and socket
What movement does a ball and socket joint allow
Flection, extension, abduction, adduction, circumduction, rotation
What movement does a hinge allow
Plantar flexion, Doris flexion, flexion, extension
What type of joint is in the knee
Hinge
What type of joint is in the hip
Ball and socket
What type of joint is in the shoulder
Ball and socket
What type of joint is in the elbow
Hinge
What type of joint is in the ankle
Hinge
What does the Skelton provide
Movement, mineral storage, protection, production of red blood cells, shape, support
What is the acronym for the skeleton functions
M,M,P,P,S,S
How many bones do you need to know for the gcse
18 (including 2 sets of phalanges, (meta)tarsals, (meta)carpals)
What are the possible movements at a joint
Flexion, extension, abduction, adduction, plantar flexion, Doris flexion, rotation, circumduction
