1901 Amer. Jrnl. Physiol. 6 155 Following Cohnheim's suggestion..we use the term ‘mucoid’, instead of the previously accepted ‘mucin’, to designate this substance. We agree with Cohnheim that..the term ‘mucin’ may be best applied to the glucoproteids elaborated by true secretory cells, and the term ‘mucoid’ to similar substances in the tissues.
