1

5 finger method to muscles of the arm that attach to the medial condyle

Thumb = Pronator teres
Index = Flexor Carpi Radialis
Middle = Palmaris Longus
Ring = Flexor digitorum Superficialis
Pinky = Flexor carpi Ulnaris

2

Size and shape of the arm

Depends on the size of the brachialis muscle
Curls in the pronate postion (Revese curls) will work on this muscle.

3

Palmar Fossa

Protects hand from puncture

4

Palmaris longus

Missing in 16% of people, function with it out
Tenses the fassa can be moved to repair liagmanets

5

Biceps brachii and supanator muscles

Work together to supinate the hand

6

Flexor Retinaculum

If cut or torn will bow string the tendons

7

Sever tendons of the hand

Cuts around the finger or palm will send tendons into the forearm as they contract.

8

Saltue Muscle

Adductor Polliscis

9

Tiny muscles of the palm

Help pull on tendons and deal with fine finger movement

10

Posterior arm

lateral epipcondyle for all muscles
All extend and one supinates

11

Two tenonds for the index finger

Extensor indicis and extensor digitorum

12

9 tendons of the hand

front and back

13

Anatomical Snuff box

Pull the thumb up and back, and a pocket will develop
Radial artery is in the pocket

14

Hypertrophy

Get bigger in size as you are active

15

Atrophy

Muscles shrink when not in use

16

Abductor pollicis longus

Hitchhiker thumb

17

5 Superficial muscles at the lateral epicondyle

Extensor carpi radialis longus
Extensor carpi radialis brevis
Extensor digitorum communis
Extensor Digiti Minimi
Extesnor Carpi Ulnaris

18

5 deep posterior muscles, Proximal to distal supinator

Abductor pollicis longus
Extensor pollicis brevis: Inserts on proximal phalanx
Extensor Pollicis Longus: Inserts on the distal phalax
Extensor Indicis
