The 1st carpometacarpal (CMC) joint is a ___________________ joint.
Saddle - Unique Movements - Flexion (frontal plane) - Extension (frontal plane) - Abduction (sagittal plane) - Adduction (sagittal plane) - Opposition (oblique) - Circumduction
Joints of the hand
1. Carpometacarpal joints (CMC) 2. Metacarpophalangeal joints (MCP) 3. Interphalangeal joints - Distal interphalangeal joints (DIP) - Proximal interphalangeal joints (PIP)
Interphalangeal (PIP and DIP) articulations are __________________________, and include ________________________ movements.
1. Hinge 2. Flexion and extension
Carpometacarpal (CMC) articulations are ______________________.

The movements of the wrist are ________________________.
1. Flexion 2. Extension 3. Ulnar Deviation (Adduction) 4. Radial Deviation (Abduction) 5. Circumduction
Bones of the hand
1. Metacarpals (5) 2. Phalanges - Distal - Middle - Proximal
Joints of the wrist
1. Radiocarpal joint (wrist joint) - Between the forearm (radius) and the wrist (carpals) 2. Ulnarcarpal joint - Between the forearm (ulna) and the wrist (carpals) 3. Intercarpal joints - Between all carpal joints
The ___________________ is the most commonly fractured carpal. The _________________________ is the carpal that is most commonly dislocated during FOOSH.
1. Scaphoid 2. Lunate
The ______________________ directly articulate with the distal end of the radius.
