Q

Muscle Nomenclature

A
  • Location – ex Pectoralis (Chest)
  • Origin and Insertion – Brachioradialis (extends from “brachio” meaning arm to the radius)
  • Number of heads – e.g., Biceps (“bi” = two + “ceps” = head)
  • Function – ex. Flexor digitorum (flexes the digits)
  • Size – e.g., Vastus (means large)
    *
    Shape – e.g., Deltoid (means triangular)
    *
    Orientation of fasciculi – e.g., Rectus (means straight)
