Question 3

what are the three joint types and their range of movement

Answer 3

fibrous fixed, cartilaginous limited movement, synovial free

Question 4

what types of synovial joints are there

Answer 4

pivotal, hinge, saddle, ball and socket, gliding, ellipsoid

Question 5

what are all the movements joints can do

Answer 5

flexion, extension, abduction, adduction, pronation, supination, elevation, depression, retraction, protraction, plantar flexion, dorsiflexion, inversion, eversion

Question 6

describe the movement for each of the joint movements: flexion, extension, abduction, adduction, pronation, supination, elevation, depression

Answer 6

flexion decreasing the angle between two bones, extension increasing the angles between two bones, abduction moving a body part away from the midline of the body, adduction moving the a body part towards the midline of the body, pronation twisting inwards, supination twisting outwards, elevation raising a body pard, depression, lowering a body part

Question 7

describe the movement for each of the joint movements: retraction, protraction, plantar flexion, dorsiflexion, inversion, eversion

Answer 7

retraction pulling a body part backwards, protraction pushing a body part forwards, plantar flexion bending the foot away from the shin, dorsiflexion bending the foot toward the shin, inversion rotating the foot inward, eversion rotating the foot outward
