Prepared microscope slide. Chordata: Amphibian skin (frog) sec.
The integument of a frog consists of two layers: the epidermis (squamous epithelium) and the dermis (connective tissue). The epidermis in frogs comes from ectoderm whereas the dermis mainly comes from mesoderm. The epidermis of an amphibian contains mucous glands and poison glands, but no hair follicles or sweat glands.From the Southern Illinois University School of Medicine, THIS image shows the basic epithelial configuration of a gland, with surface epithelium (here a nonkeratinized, stratified squamous epithelium) invaginating to form a simple gland, with one single secretory unit connected to the surface by a short duct.
These prepared slides are of very high quality produced in the U.S. by Lee Gonzales, a licensed histologist. The attached image of frog skin is of the slide being offered, at 400x.
