Most distal bones of the hand/wrist? how many? Phalanges, 14
2nd group of bones in hand/wrist? how many? metacarpals (palm), 5
third group of bones in hand/wrist? how many? carpals (wrist), 8.
Two beaklike process on ulna? Olecranon and coronoid process.
What process can be palpated on on the posterior aspect of elbow joint? Olecranon process.
What is the coronoid tubercle? Medial margin of he coronoid process, opposite the radial notch.
The large concave notch that articulates with the distal humerus? Trochlear notch.
What are the depression/s on the anterior side of the humerus? Coronoid (above trochlea) and radial fossa (above capitulum)
What are the depression/s on the posterior side of humerus? olecranon fossa.
What are the three concentric arcs of a True Lateral elbow? Trochlear sulcus, outer ridges of capitulum and trochlea, and trochlear notch of ulna.
During the act of pronation, what happens? Radius crosses over the ulna.
Radius is lateral or medial? lateral.
MCP of 1st-5th joints are what type? Ellipsoidal. (flex/extension, ab,add, circumduction)
