Mid Term Exam Review Flashcards
sagittal plane with frontal axis promotes:
flexion/ extension
frontal plane with sagittal axis promotes:
abduction/ adduction
transverse plane with vertical axis promotes
internal/ external rotation
flexion/ extension occurs in:
sagittal plane/ frontal axis
abduction/ adduction occurs in:
frontal plane/ sagittal axis
internal/ external rotation occurs in:
transverse plane/ vertical axis
isometric
static movement
- promotes stability
isotonic
concentric/ eccentric
- promotes movement
concentric
- shortening
- away from gravity
eccentric
- lengthening
- towards gravity
agonist
antagonist
humeroulnar joint
- hinge
- uniaxial
- flexion/ extension
humeroradial joint
- modified hinge
- biaxial
- flexion/ extension & rotation
proximal radioulnar joint
- pivot
- uniaxial
- pronation/ supination
cubitus varus
medial angulation of the elbow (more than normal)
cubitus valgus
lateral angulation of the elbow
joints involved in forearm rotation
- humeroradial
- proximal & distal radioulnar
flexors of the elbow
- biceps brachii
- brachialis
- brachioradialis
primary function of biceps brachii :
assists with :
- elbow flexion
- forearm supination
primary function of brachialis :
elbow flexion
primary function of the brachioradialis :
- elbow flexion
- can pronate/ supinate the thumb into a neutral position
extensors of the elbow
- triceps brachii
- anconeus
3 heads of the triceps brachii
- long
- lateral
- medial
