Flashcards in Week 9: Sensations Deck (24):
1

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

dermatome

2

group of muscles that a single spinal nerve root innervates

myotomes

3

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

Ulnar N.

4

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

Median N.

5

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

Radial N

6

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

Radial N.

7

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

Medial N.

8

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

Ulnar N.

9

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

Grasp

10

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

Pinch

11

This grip is used for grasp rather than manipulation

Power Grip

12

This grip is used for manipulation rather than grasp

Precision Grip

13

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

Hook Grip
[FDS and FDP]

14

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

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

15

In this grip, fingers and thumb adduct onto the object

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

16

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

Fist grip
[FDS and FDP, AP/OP]

17

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

Lumbrical grip

18

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.

2 point pinch
[FDS and FDP, AP, FPB and FPL]

19

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.

3 point pinch
[FDS, maybe FDP, Interossei, AP, FPB, FPL]

20

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

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

21

This type of pinch is the least precise

lateral pinch

22

What is the general resting hand position for splinting?

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

23

5 indications for splinting?

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

24

4 main purposed for splinting?

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