|
only one elbow muscle on the common origin
|
pronator teres
|
|
|
how many superficial, intermediate, deep muscles
|
3 superficial, 1 intermediate, 3 deep
|
|
|
all superficial and intermediate muscles are attach at
|
a common flexor origin which is the medial epicondlye and epicondylar ridge
|
|
|
the more superficial the muscle
|
the more superior on the common origin, and the more proximal the action
|
|
|
the more deep the muscle
|
the more distal the action
|
|
|
the more superior the muscle
|
the more action at the elbow and at the wrist
|
|
|
the more inferior the muscle
|
the less action at the elbow
|
|
|
the more distal the attachment of the muscle
|
the more hand and finger function is involved
|
|
|
medial humerus anterior flexors in order of superior to inferior attachment
|
pronator teres
flexor carpi radialis palmaris longus flexor carpi ulnaris flexor digitorum superficialis no deep muscles are on the common origin |
|
|
outlaw muscles of anterior forearm
|
pronator teres and quadratus. they do not cross the wrist. 1st muscle and most deep muscle of anterior forearm are outlaws
|
|
|
wrist flexor properties/range of motion, and daily living ROM, train with?
|
twice as strong as its antagonistic exensors (better pullers than pushers)
ROM=70-90 Daily living ROM=10-15 train with a rubber band/rolling dumbbell |
|
|
wrist flexors carpal tunnel formation ulnar side and radial side
|
pisiform and hamate on ulnar side
trapezium and scaphoid form tunnel walls on radial side |
|
|
wrist flexors carpal tunnel formation on the floor/ceiling
|
capitate/lunate are floor of tunnel
flexor retinaculum is ceiling of tunnel |
|
|
flexor carpi radialis description
|
action at the wrist, mutual neutralizer for radial deviation. located tendon of anterior wrist
|
|
|
flexor carpi radialis o/i/a
|
o:med. epicondylar ridge
i:base of #2 and sometimes #3 metacarpal A:wrist/elbow flexion/radial deviation |
|
|
palmaris longus description
|
can be missing in some people/ action at the wrist. palpate exact center of anterior wrist, usually runs outside of retinaculum. forms the palmar aponeurosis for extensive palmar attachment
|
|
|
palmaris longus o/i/a
|
o: med. epicondyle
i:palmar aponeurosis a:wrist/elbow flexion/palmar cupping |
|
|
flexor carpi ulnaris description
|
action at the wrist/mutual neutralizer for ulnar deviation with extensor carpi ulnaris/ located tendon on little finger side
|
|
|
flexo carpi ulnaris o/i/a
|
o:medial epicondyle;olecranon process
i:hamate, pisiform, #5 metacarpal a:wrist/elbow flexion/ulnar deviation |
|
|
intermediate/deep forearm description
|
one on common origin. 3 on radius/ulna deep
all have very distal digit action except for the outlaw. one is specialized for the thumb, 2 share digits |
|
|
flexor digitorum superficialis description
|
intermediate layer, action at the fingers. more distal and more deep location means actions are more distal. single tendon splits into 4 in palm and each 4 split in 2 at middle phalanx
|
|
|
flexor digitorum superficialis o/i/a
|
o:med. epicondyle, coronoid process, oblique line of radius
i:base and lateral surface of middle phalanx 2,3,4,5 a:wrist/finger flexion |
|
|
deep muscles origins move between ulna and radius
|
1st - ulna.. flexor digitorum profundus
2nd-radius..flexor pollicis longus 3rd- ulna...pronator quadratus |
|
|
flexor digitorum profundus description
|
first muscle to leave common origin all together. most deep and most distal flexor. most action at fingers and hand. beings with the origin interchange at the ulna. last of true wrist flexors.
|
|
|
flexor digitorum profundus o/a/i
|
o: proximal anterior/medial ulna
i:base of the distal phalanx of 4 fingers a:finger/wrist flexion |
|
|
flexor pollicis longus description
|
only thumb muscle organized with forearm.
|
|
|
flexor pollicis longus o/i/a
|
o:anterior radius
i:base of distal phalanx #1 a: wrist and thumb flexion |
|
|
pronator quadratus description
|
pronation only, outlaw, does not cross wrist, deepest muscle.
|
|
|
pronator quadratus
|
o: ant. ulna
i: anterior radius a: pronation |
|
|
medial epicondylitis
|
pain in the common flexor origin. irritation an inflammmation due to extreme finger and or wrist flexion. 5 muscles attached and pulling on one location
|
|
|
medial epicondylitis golf elbow
|
players between age of 35-60, brief case carriers, carpenters, word processors. radiating pain over medial elbow
|
|
|
causes of golf elbow
|
underlying rotator cuff weakness. compensate for internal rotation weakness by flick of the wrist.
Poor body positioning, compensate for good follow through with flick of the wrist, rather than trunk and hips |
