1
Q

Area of the skin innervated by the sensory axons within each nerve root

A

dermatome

2
Q

group of muscles that a single spinal nerve root innervates

A

myotomes

3
Q

This nerve innervation provides sensation to half of the 4th and the entire 5th finger; also it is important in muscles in the forearm and hand that allow for wrist and finger flexion

A

Ulnar N.

4
Q

This nerve innervation provides sensation go the thumb and 1-4 fingers; it also is important to the muscles of the forearm and hand that allow for a pincer grasp

A

Median N.

5
Q

This nerve innervation provides sensation to a portion of the skin on the back of the hand; also, it is important to the arm and forearm muscles that extend the elbow, wrist, and finger

A

Radial N

6
Q

This nerve is made from the posterior cord of the brachial plexus

A

Radial N.

7
Q

This nerve is made from the medial and lateral cords of the brachial plexus

A

Medial N.

8
Q

This nerve is made from the medial cord of the brachial plexus

A

Ulnar N.

9
Q

This occurs when the thumb applies counter to maintain and stabilize a movement

A

Grasp

10
Q

This is used for accurate or refined movement for manipulation; it usually occurs between flexor surface of 1 or more fingers and thumb

A

Pinch

11
Q

This grip is used for grasp rather than manipulation

A

Power Grip

12
Q

This grip is used for manipulation rather than grasp

A

Precision Grip

13
Q

In this grip, only the flexed fingers are used, thumb not involved

A

Hook Grip

[FDS and FDP]

14
Q

In this grip, grasps objects that are cylindrical in shape or large enough that the thumb does not touch the fingers

A

Cylindrical Grip

[FDS, FDP, PI and DI, FPL and FPB, AP, OP]

15
Q

In this grip, fingers and thumb adduct onto the object

A

Spherical grip

[PI and DI, FDP and FDS, ED, OP, FPL and FPB, AP]

16
Q

In this grip, skin of the palmar surface of the fingers and the palm curve around the handle and the thumb lies in opposition over the finger tips

A

Fist grip

[FDS and FDP, AP/OP]

17
Q

In this grip, MCP joints of fingers are flexed with IP joints extended; thumb is opposed across the palmar surface of the fingers

A

Lumbrical grip

18
Q

In this grip, all joints of the index finger are flexed and finger tip is brought into contact with the tip of the abducted thumb.

A

2 point pinch

[FDS and FDP, AP, FPB and FPL]

19
Q

In this grip, all joints of the index and long fingers are flexed and the finger tips are brought into contact with the tip of the abducted thumb.

A

3 point pinch

[FDS, maybe FDP, Interossei, AP, FPB, FPL]

20
Q

In this grip, extended thumb is held on the radial side of the index finger

A

Lateral pinch

[FDP, FDS, First Dorsal Interossei, FPL, FPB, AP]

21
Q

This type of pinch is the least precise

A

lateral pinch

22
Q

What is the general resting hand position for splinting?

A

about 20* wrist extension
fingers slightly flexed
thumb slightly opposed and fwd

23
Q

5 indications for splinting?

A
  1. edema
  2. bone/joint alignment
  3. tendon/ligament disruption
  4. muscle weakness
  5. surgical protection
24
Q

4 main purposed for splinting?

A
  1. assist for hand position or movement
  2. protection
  3. support (immobilization and mobilization)
  4. pain management
