27
Q

diarthroses found

A

ends of long bones; also called synovial joints

28
Q

synovial joints 6 basic characteristics

A

joint capsule, articular cartilage, joint cavity, synovial fluid, synovial membrane, accessory structures (ligaments, cartilage, tendons, bursae)

29
Q

joint capsule

A

envelope that surrounds synovial joint

30
Q

articular cartilage

A

hyaline cartilage surrounds ends of ones

31
Q

joint cavity

A

space inside of the joint capsule

32
Q

synovial fluid

A

fluid inside of the joint cavity

33
Q

synovial membrane

A

secretes synovial fluid

34
Q

accessory structures

A

helps stabilize and protects joints

35
Q

sensory nerves and blood vessels purpose in joints

A

detect pain and amount of stretch in join, nourish tissues present

36
Q

functions of synovial fluid

A

lubricate surface of articular cartilages and reduce friction, nourish chondrocytes, act as shock absorber

37
Q

accessory structures of synovial joints

A

menisci, ligaments, tendons

38
Q

menisci

A

thin fibrous cartilage between surfaces of some joints

39
Q

what are ligaments and tendons made of?

A

dense regular CT

40
Q

ligaments connection

A

bone to bone

41
Q

tendon connection

A

bone to muscle

42
Q

bursae

A

sac structure containing synovial fluid and are lines by synovial membrane

43
Q

strength vs mobility

A

less moveable = stronger joint

44
Q

types of joints

A

ball and socket, condyloid joint, gliding joint, hinge joint, pivot joint, saddle joint

45
Q

most moveable joint

A

ball and socket

46
Q

condyloid joint

A

allows for movement in few different planes

47
Q

gliding joint

A

movement is slight

48
Q

hinge joint

A

permit angular motion in single plane

49
