Trapezius muscle
Extracted from the Wikipedia article Trapezius.
Name and history
The trapezius muscle resembles a trapezium in North American English, also known as a trapezoid in British and other forms of English, meaning an irregular quadrilateral. The word "spinotrapezius" refers to the human trapezius, although it is not commonly used in modern texts. In other mammals, it refers to a portion of the analogous muscle.
