In the upper part of the internal occipital crest, a small depression is sometimes distinguishable; it is termed the [[vermian fossa]] since it is occupied by part of the [[vermis]] of the [[cerebellum]]. ==External links== * {{RocheLexicon|34257.000-2}} {{Gray's}} {{Skull}} {{musculoskeletal-stub}} [[th:สันด้านในของท้ายทอย]]
