Q

what is synovial fluid and where is it found

A

Q

What are the classes of joints

A

synarthroses
amphiarthroses
diarthroses

109
Q

what are synarthrotic/fibrous joints

A

non movable
most fibrous joints
innelastic connective tissue
lack of joint cavity
i.e. cranial sutures, gomphoses (articulation of tooth in alveolus), syndesmoses (ligaments holding joint together)

110
Q

what are amphiarthrotic joints

A

semi movable
mostly cartilaginous
i.e. intervertebral discs

111
Q

what are diarthrotic joints

A

freely moveable joints
synovial joints

112
Q

what are cartilaginous joints

A

formed by cartilage and usually semimoveable

113
Q

what are synchondroses

A

joints
mostly unmoveable-synarthrotic
hyaline cartilage
i.e. costal cartilage and epiphyseal plate

114
Q

what are symphyses

A

joints
shock absorber and limited movement-amphiarthrotic

115
Q

what are synovial joints

A

moveable
diarthroses
most joints of the body

116
Q

what state are tendons when muscle is relaxed

A

tendons are tight

117
Q

what state are tendons when the muscle is active

A

tendons are not tight

118
Q

what is a tendon sheath

A

elongated bursa that wraps around tendon

119
Q

what is Osgood Schalatter’s

A

disease that mainly affects boys that excercize too much
pull on patellar tendon on tibial tuberosity
build extra bone that tears patellar tendon

127
Q

what is arthritis

A

inflammation of the joints

128
Q

what is osteoarthritis

A

deterioration of the articular cartilage (by age, stress, inury) which then leads to the formation of calcifications or bone spurs
little actual inflammation occurs

129
Q

what is rheumatoid arthritis

A

autoimmune disease
severe inflammation
pain
fibrous tissue stiffness and may ossify to immobilize joint

130
Q

what is gouty arthritis

A

genetic disorder in the ability to metabolize uric acid
uric acid crystals build up in the soft joint tissues and causes their inflammation and destruction
usually men

131
Q

what is a sprain

A

twisting of the joint with stretching or tearing of ligaments

132
Q

what is a strain

A

a pulling of a muscle tendon and other connective tissues in muscles, but not the joint tissues

133
Q

what is luxation/dislocation

A

a bone pulls away from its position in the socket of the joint

134
Q

what is subluxation

A

partial dislocation

135
Q

what is separation

A

when the fibrous tissue in syndesmosis stretches or tears
