superficial forearm flexors

• Flexor Carpi Radialis:

  O: Common flexor origin (CFO) on medial epicondyle of humerus

  R: Oblique: laterally & downwards

  I: Palmar aspect of base of 2nd and 3rd MCs

  A: Flexion and radial deviation of the wrist

  NS: Median Nerve (C5,6,7,8, T1)
• Flexor Digitorum Superficialis:

  O: Long linear origin from two heads

  Medial: CFO, ulnar collateral ligament and the sublime tubercle (on medial coronoid process of ulna)

  Lateral: upper 2/3 anterior border of radius (anterior to oblique line)

  R: Distally and slightly laterally

  I: Forms four tendons that insert into palmar aspect of base of intermediate phalanx of four medial fingers

  A: Flexion of PIP, MCP and wrist joints

  NS: Median nerve (C5,6,7,8,T1)
• Flexor Carpi Ulnaris:

  O: Two heads, Humeral head: CFO

  Ulnar head: Medial border olecranon & posterior border ulna

  R: Distally

  I: Pisiform

  A: Wrist flexion and ulnar deviation

  NS: Ulnar Nerve ((C7),C8,T1)
• Palmaris Longus:

  O: CFO

  R: Distally

  I: Superficial surface of flexor retinaculum and palmar aponeurosis

  A: Weak flexor of the wrist & tightens the palmar fascia. May assist with flexion of the digits.

  NS: Median nerve (C5,6,7, 8,T1)
