chapter 33 Flashcards
(36 cards)
articulation and joint
the area where a bone meets another bone
how are articulations and joints classified
fibrous - no movement
cartilaginous - slight movement
synovial - free movement
type of synovial joints (6)
ball-and-socket condyloid gliding joint Hinge joint Pivot joint Saddle Joint
Abduction
lateral movement away from the midline of the body
adduction
lateral movement toward the midline of the body
circumduction
turing in a circular motion
combinds adduction and abduction flexion and extension
flexion
the state of being bent
extension
the state of being straight
hyperextension
the state of exaggerated extension results often in an angle greater than 180°
dorsiflexion
backward bending of the hand of foot
plantarflexion
flexion of the foot
rotation
turning on an anxis
internal rotation
a body part turning on it axis toward the midline of the body
external rotation
a body part turning on it axis away from the midline
pronation
the assumption for the prone position
supination
the assumption of the supine position
what is orthopedics
refers to the correction or prevention of disorders of the body structures used in locomotion
tonus
a term used to describe the state of slight contraction
- normal state of skeletal muscles
what factors affect movement and alignment
developmental level muscular, skeletal and nervous system problems mental health lifestyle attitude and values fatigue and stress external factors
exercise
active exertion of muscles involving the contraction and relaxation of muscle groups
muscle contraction types
isotonic
isometric
isokinetic
isotonic
involves shortening of muscles and active movement
isometric
involves muscle contraction without shortening
isokinetic
involves muscle contraction with resistance provided at a constant rate by an external device
