-
What is a bursae?
small fluid filled pocket that emptied upon compression
-
What are menisci?
pads of cartilage located between the bones of a synovial joint used for cushioning
-
Two flat surfaces sliding past each other is what type of movement?
gliding
-
Rotation towards the midline is known as:
medial rotation
-
Rotation away from the midline is known as:
lateral rotation
-
Decreasing the angle between two bones is known as:
flexion
-
Increasing the angle between two bones is known as:
extension
-
Extension of a joint beyond anatomical position is known as:
hyperextension
-
Movement of a joint away from the midline is known as:
abduction
-
Movement of a joint towards the midline is known as:
adduction
-
Rotating the palm so that the thumb is oriented towards the midline is called:
pronation
-
Rotating the palm to the thumb is oriented away from the midline is called:
supination
