Lectures 6-7 - Articular Flashcards
What is human motion caused by?
levers being accelerated about axes by applying torques
In what plane does flexion and extension take place?
sagittal
What movement takes place in the frontal plane?
abduction and adduction
What movement happens in the transverse plane?
rotation
Rotation is the movement about the longitudinal axis of a limb. Which is not included in rotation?
a) internal (medial) rotation of the shoulder
b) external (lateral) rotation of the shoulder
c) adduction / abduction
d) supination/ pronation of the forearm

d) Hyline Cartilage
e) Joint Cavity
f) Extrinsic ligaments
there is no synovial cover, it is synovial membrane
What does synovial membrane in synovial joints do?
covers the joint cavity
What are the two joints of the pectoral girdle?
clavicle & sternum = sternoclavicular
clavicle & scapula = acromioclavicular
Which two are not movements of the pectoral girdle?
a) elevation & depression
b) protraction & retraction
c) adduction & abduction
adduction and abduction
