Spelling Notes
Both "anulus" and "annulus" are acceptable spellings. Gray's Anatomy uses "annulus fibrosus," Terminologia Anatomica uses "anulus fibrosus," and Nomina Anatomica uses both forms. Etymologically speaking, anulus seems to be the correct spelling as it is the diminutive of L. anus, a ring, hence anulus, a little ring.
"Fibrosus" has no correct alternative spelling; "fibrosis" has a different meaning and is incorrect in this context.

Of chemic blood, warned of the coming fury.
By the sea’s side hear the dark-vowelled birds.”
