Misc. Flashcards
Proximal attachment of Dorsal Interossei?
Adjacent sides of metacarpal (Bipennate)
Distal attachment of Dorsal Interossei
Digits 2-4 Bases of Proximal Phalanges ; Extensor expansions
Proximal attachment of Palmar Interossei
PALMAR surface of 2nd 4th and 5th metacarpal as UNIPENNATE
It doesn’t need to attach to the 3rd metacarpal because the 3rd digit cannot be adducted
Distal attachment of Palmar Interossei
Base of PROXIMAL phalanx and Extensor expansions of digit 2, 4, 5
Adductor Pollics Proximal Attachment
Oblique head: Base of 2nd and 3rd metacarpals; Capitate adjacent carpal bones
Transverse head: Shaft of 3rd metacarpal
Adductor Pollicis Distal Attachment
Proximal Phalanx of thumb
Lumbricals proximal attachment
Lateral 2 tendons of FDP as Unipennate
Medial 3 tendons of FDP as Bipennate
Distal Attachment of lumbricals
RADIAL SIDE of extensor expansions of digit 2-5
Flexor digitorum superficialis Proximal attachment

Radial head: Anterior Radius
Flexor Digiti Minimi Proximal attachment
Hook of hamate
Flexor Retinaculum
Flexor digiti minimi AND abductor digit Minimi distal attachment?
Base of 5th proximal phalange
(What pinky muscle attaches to the 5th metacarpal?)
Proximal attachment of Abductor Digiti Minimi?
Pisiform
(he is small so he gets abducted)
Extensor Indicis PROXIMAL and DISTAL ATTACHMENT?
Posterior surface of ulna AND Interosseous Membrane
Extensor Expansion of 2nd digit
Abductor Pollicis Longus proximal attachment?
Posterior ULNA RADIUS and interosseous membrane
Distal attachment of Abductor Pollicis Longus?

Extensor pollicis brevis proximal attachment
Posterior surface of radius and interosseous membrane
Extensor pollicis brevis distal attachment
Base of proximal phalanx of thumb
Extensor pollicis longus proximal attachment
Posterior Ulna and interosseus membrane
Distal attachment of the Extensor Pollicis Longus
Base of distal phalanx of thumb

Hook of Hamate
Flexor Retinaculum
Opponens Digiti Minimi distal attachment
Medial Border of 5th metacarpal
Flexor Digitorum Profundus Proximal Attachment
Proximal ulna and interosseous membrane
Flexor Digitorum Profundus Distal Attachment
Medial Part: Base of distal phalax of digit 4 and 5
Lateral Part: Base of distal phalanx digits 2 and 3
Flexor Pollicis Longus Proximal attachment
Anterior radius and and adjacent interosseous membrane
Distal attachment of Flexor pollicis longus
Base of distal phalanx of thumb
Pronator Quadratus Proximal and Distal attachment?
Proximal: Anterior distal Ulna
Distal: Anterior distal Radius
Distal attachment of Opponens Pollicis
1st metacarpal
What carpals articulate with the radius?
Scaphoid and Lunate
What carpal articulates with the thumb?
Trapezium
Proximal attachment of Flexor Carpi Ulnaris
Posterior Ulna and Medial Epicondyle (common flexor tendon)
Pronator Teres proximal attachment
Coronoid process of ulna AND medial epicondyle
what travel through the interosseous membrane?
Anterior Interosseous Nerve
Underrated Anconeus action?
Abducts ulna during pronation
also assists with elbow extension and elbow stabilitity
What forms the cubital fossa?
Brachioradialis
Pronator teres
Supinator and brachialis
Imaginary line between two epicondyles, forming ceiling
What goes through the cubital fossa?
- Biceps Tendon
- Brachial Artery
- Median Nerve
- *Median cubital vein
3 Actions of the biceps?
Short head prevents dislocation
Supination
Elbow Flexion
Biceps Brachii Proximal and Distal attachment?
Short head: Corcoid process
Long head: Supraglenoid Tubercle
Distal attachment: Tuberosity of radius and fascia of forearm via bicipital aponeurosis
Brachioradialis Action
Flex the elbow in midpronated position (humerolnar joint)
Assists to pronate and supinate the forearm when these
movements are resisted/from end range (humeroradial joint)
Brachialis Proximal and Distal attachment
Distal half of anterior Humerus -> Ulna Tuberosity and coronoid process of ulna

Flexor Carpi Ulnaris Proximal and Distal attachments
PROXIMAL: Humeral head: Common flexor tendon from
medial epicondyle of humerus
Ulnar head: Posterior ulna
DISTAL: Pisiform, hook of the hamate, and base of 5th
metacarpal
