Q

What is the function of the carpals

A 
• No muscle attachments
• Intercalated segment – movement (muscle cross tehse bones and insert distally) - the bones adapt the shape depending on the muscles beyond them 
• Hand can conform to shape the task
• Protected from abnormal movements
• Scaphoid susceptible to avascular
dictated by muscles acting distally
requires by strong ligaments
necrosis because of retrograde blood supply

Q

What muscles are in layer 2 f the forearm

A

Flexor digitorum superficialis • ORIGINATES FROM MEDIAL
• INSERTS INTO MIDDLE PHALANGES
• INDIVIDUAL MUSCLE BELLIES • MAY NOT HAVE FDS TO THE LITTLE
EPICONDYLE/ RADIUS AND ULNA
OF THE FINGERS
FINGER

17
Q

What muscles are in layer 3 of the forarm

A
  • FDP ORIGINATES FROM THE ULNA AND INSERTS INTO DISTAL PHALANGES OF THE FINGERS
  • SINGLE MUSCLE BELLY (ALL FINGERS
  • FPL ARISES FROM RADIUS AND TOGETHER) INSERTS INTO THUMB DISTAL PHALANX
18
Q

What are the extensors of the wrist

A 
• EXTENSOR CARPI RADIALIS
LONGUS – 2nd METACARPAL
• EXTENSOR CARPI RADIALIS BREVIS
– 3rd METACARPAL
• EXTENSOR CARPI ULNARIS – 5th
METACARPAL
19
Q

Describe the finger extensors

A 
• CENTRAL SLIP – INSERTS INTO BASE • 2 LATERAL SLIPS – INSERT INTO
• WORK TOGETHER BUT CAN BE
OF MIDDLE PHALANX
BASE OF DISTAL PHALANX
DAMAGED IN ISOLATION
20
Q

What are the other finger extensors

A

• EXTENSOR INDICIS (PROPRIUS)
(LIBRARIAN SHUSH MUSCLE) • EXTENSOR DIGITI MINIMI
(MACHIAVELLIAN LAUGH)
• TOGETHER – SHOOTS A WEB

21
Q

What are the thumb extensors

A 
• EXTENSOR POLLICIS BREVIS – BASE
OF PROXIMAL PHALANX
• EXTENSOR POLLICIS LONGUS –
BASE OF DISTAL PHALANX (RETROPULSION)
• ABDUCTOR POLLICIS LONGUS
22
Q

What are the 5 groups of hand muscle s

A

• LUMBRICALS • INTEROSSEI • THENAR EMINENCE • HYPOTHENAR EMINENCE • THUMB ADDUCTOR
(AND PALMARIS BREVIS – YEAH, WHO CARES)

23
Q

What is the function of the lumbar I also

A
  • CROSS THE NEUTRAL AXIS BETWEEN FLEXION AND EXTENSION OF THE DIGITS
  • ARISE FROM FDP TENDONS AND INSERT INTO EXTENSOR EXPANSIONS

• ALLOW OPPOSING MOVEMENTS AT
NEIGHBOURING JOINTS

24
Q

Wha are the interossei

A
  • DORSAL ABDUCT BIPENNATE (dab)
  • PALMAR ADDUCT UNIPENATE (pad)
  • ALSO CROSS THE NEUTRAL AXIS \ THEREFORE ASSIST LUMBRICALS IN FLEXION AT MCPJs AND EXTENSION AT IPJs
25
Q

What are the The are muscles

A

• FLEXOR POLLICIS BREVIS • ABDUCTOR POLLICIS BREVIS • OPPONENS POLLICIS BREVIS
BULK UP THE THUMB CHIEF FUNCTION IS OPPOSITION

26
Q

What are the hypothecate muscles

A

• FLEXOR DIGITI MINIMI • ABDUCTOR DIGITI MINIMI • OPPONENS DIGITI MINIMI
BULK UP HYPOTHENAR EMINENCE CHIEF FUNCTION IS POWER GRIP

27
Q

Describe the thumb adductor

A

• CLOSES OFF GAP BETWEEN THUMB
AND INDEX METACARPALS
• KEY COMPONENT OF PINCH GRIP • BASIS OF FROMENT’S TEST

28
Q

What is palmaris brevis

A

• INVOLUNTARY CONTROL • CAN LOSE CONTROL GIVING RISE

TO A TWITCHY PATIENT

29
Q

Describe the nerve supply to the extrinsic muscle

A
  • RADIAL NERVE – POSTERIOR COMPARTMENT
  • ULNAR NERVE – FCU, ULNAR HALF OF FDP
  • MEDIAN NERVE – EVERYTHING ELSE
30
