(5 points) - nails - a close modification of the epidermis that forms a clear protective applications course of instruction on the dorsal surface of the distal part of a finger or toe. - sweat glands - distributed over the entire bark surface withdraw the nipples and parts of the external genitalia. - sebaceous (oil) glands - dental consonant glands found all over the body except on the palms and soles.They are small on the body tree trunk and...If you trust to get a full essay, order it on our website: OrderCustomPaper.com
