athletic injurys test

Question 1

what are the three types of joints and the movements of each

Answer 1

fibrous (synarthroidal) no range of movement sutures in skull bones and teeth
cartilaginous (amphiarthroidal) slightly moveable sacroiliac symphysis pubis intervertebral joints
synovial (diarthroidal) freely moveable (many types)

Question 2

what are the six types of synovial joints and examples for each

Answer 2

ball and socket ex shoulder and hip joints

gliding ex intercarpal and intertarsal joints

Question 3

what are the six types of synovial joints and examples for each

Answer 3

ball and socket ex shoulder and hip joints
gliding ex intercarpal and intertarsal joints
hinge ex knee elbow joints of phalanges
pivot ex atlantoaxial joint proximal radio ulnar joint
saddle ex carpometacarpal (thumb joint)
ellipsoid ex radio carpal joint (wrist)

Question 4

define tendons

Answer 4

attach muscle to bone made of protein flexible bc of collagen

Question 5

define ligaments

Answer 5

attach bone to bone less flexible joint stabalizers

Question 6

bursae

Answer 6

small fluid filled sacks bw tendons ligaments and bones to reduce friction

Question 7

joint capsule

Answer 7

a fibrous structure that consists of a synoibal memebrane an a fibrous capsule

Question 8

articulating cartilage

Answer 8

located at the end of bones to allow smoooth mobement bw bones adn act as a shock absorbers

Question 9

joint cavity

Answer 9

bw two articulating bones slowly release synovial fluid which lubricates the joint reducing friction and providing nutrients

Question 10

synovial fluid

Answer 10

lubricates joints to release friction

Question 11

hyaline cartilege

Answer 11

found at the end of bones (nose larynx)

Question 12

extrinsic ligaments

Answer 12

help stabalize the joint (bones to bones)

Question 13

vascularity

Answer 13

the amount of blood a tissue requires

Question 14

tendonitis

Answer 14

inflammation of a tendon, most commonly from overuse but also from infection or rheumatic disease

Question 15

contusion

Answer 15

soft tissue is compressed against hard bone capillaries are torn which allows bleeding into tissues causing a bruise

Question 16

strain

Answer 16

ligament or the joint capsule is stretched or torn

Question 17

acute vs chronic injurys

Answer 17

Acute injuries happen suddenly, such as sprained ankles. Chronic injuries happen after you play a sport or exercise over a long period of time. Sports injuries are first treated with R-I-C-E: Rest, Ice, Compression (pressure on the injury), and Elevation (raise the injured area above the heart).

Question 18

degree of sprains

Answer 18

1st degree is mild and should take a few days to heal
2nd degree moderate and requres rreatment from a physiotherapist
3rd degree most severe may require surgery often 6-12 months to fully recover

Question 19

bones

Answer 19

most rigid tissue they will break before they bend

Question 20

ligaments

Answer 20

are less rigid than bones but do not have the stretching properties of tendons ligaments are static joint stabilizers

Question 21

tendons and muscles

Answer 21

are dynamic stabilizers tendons are more stretchy than igaments butt will tear if pushed too far

Question 22

osteoarthritis

symptoms causes treatments and prevention

Answer 22

the protective cartilage that cushions the ends of your bones wears down over time.
symptoms: Pain. Stiffness. Tenderness. Loss of flexibility. Grating sensation. Bone spurs. Swelling.
causes genetics overuse previous injury
treatments surgery lose weight and be active
prevention be active keep a healthy body weight

Question 23

what is cte

Answer 23

chronic traumatic encephalopathy

Question 24

what is a serious injury

Answer 24

not currently a threat to athletes life but could become life threatning if not treated

Question 25

what is a non life threating injury

Answer 25

soft tissue injuries such as muscle strains ligament strains abrasions cuts and blisters
