Cards

Term
CMC Flexion
Definition
Movement of the thumb toward the fifth digit in a plane parallel to the palm (frontal plane movement)
Term
CMC Extension
Definition
Movement of the thumb away from the fifth digit in a plane parallel to the palm (frontal plane movement)
Term
CMC Abduction
Definition
Movement of the thumb away from the palm in a plane perpendicular to the palm (sagittal plane movement)
Term
CMC Adduction
Definition
Movement of the thumb toward the palm in a plane perpendicular to the palm (sagittal plane movement)
Term
Opposition
Definition
Combination of flexion and abduction to produce a movement where the tip of the 1st and 5th digits touch
Term
MCP Flexion
Definition
Bending the MCP joint so the anterior surface of the proximal phalanx moves closer to the palm
Term
MCP Extension
Definition
Straightening of the MCP joint so that the anterior surface of the proximal phalanx moves away from the palm
Term
IP Flexion
Definition
Bending of the IP joint so that the anterior surface of the distal phalanx moves toward the anterior surface of the proximal phalanx
Term
IP Extension
Definition
Straightening of the IP joint so that the anterior surface of the distal phalanx moves away from the anterior surface of the proximal phalanx
Term
CMC articulations
Definition
trapezium - MC 1
trapezoid - MC 2
capitate - MC 3
hamate - MC 4&5
Term
MCP Abduction
Definition
Occurs when the second, fourth, and fifth fingers move away from the third digit, OR when the third digit moves in either direction
Term
MCP Adduction
Definition
Occurs when the second, fourth and fifth fingers move back toward the third digit. There is no adduction for the middle finger
Term
PIP Flexion / Extension
Definition
bending / straightening occurring between the proximal and middle phalanges
Term
DIP Flexion / Extension
Definition
bending / straightening occurring between the middle and distal phalanges
Term
Extrinsic muscles originate...
Definition
outside (proximal) the hand, radius, ulna, or humerus
Term
Flexor Digitorum Superficialis OIA
Definition
O: medial epicondyle of the humerus at the common flexor tendon, coronoid process of the ulna, and proximal anterior radius
I: tendons split and insert on the sides of the middle phalanges of digits 2-5
A: PIP flexion digits 2-5,
MCP flexion digits 2-5,
assists wrist flexion
Term
Flexor Digitorum Profundus OIA
Definition
O: Upper 3/4 of ulna
I: Distal phalanges of digits 2-5, running through the split in the FDS tendon along the way
A: DIP flexion digits 2-5,
PIP flexion digits 2-5,
MCP flexion digits 2-5,
assists wrist flexion
Term
Extensor Digitorum OIA
Definition
O: lateral epicondyle of humerus at the common extensor tendon
I: bases of distal phalanges 2-5
A: DIP extension digits 2-5,
PIP extension digits 2-5,
MCP extension digits 2-5,
assists wrist extension
Term
Extensor Expansion Ligament / Extensor Hood
Definition
an extension of the extensor digitorum tendon, which turns into a small triangular shaped aponeurosis, serves as an attachment point for the lumbricales and Interossei and allows them to impart action on the DIP joint
Term
Extensor Digiti Minimi OIA
Definition
O: lateral epicondyle of humerus at the common extensor tendon
I: base of the distal phalanx of digit 5
A: DIP extension digit 5,
PIP extension digit 5,

Term
Extensor Pollicis Brevis OIA
Definition
O: posterior distal radius
I: base of the proximal phalanx of the thumb
A: MCP extension digit 1,
CMC extension digit 1
