This causes some confusion in classification. In addition some structures, such as preputial glands are sometimes called 'modified' sebaceous glands, implying a non-subclass relationship. we follow MP and MA in keeping this class generic and creating a distinct subclass for sebaceuous glands of the skin. The FMA class may be better placed under this subclass.
