The virtual histology slide box provides an introduction to the histology of general tissue types and specific organ systems. Each specimen is accompanied by a caption that provides information on staining, magnification, and the structures shown. Virtual microscopy is provided in cooperation with Smart Zoom. Complementary to this Article, the contains numerous images of captioned histopathological specimens with the same virtual microscopy feature.
General histology distinguishes between four basic types of animal tissue.
The following sections provide a range of examples for subtypes of each of these four basic types of tissue. Specific organ tissues are presented in the section onbelow.
Simple squamous epithelium
Intestinal serosa (=)
Pulmonary alveoli ( as an example of specialized epithelium)
Nonkeratinized stratified squamous epithelium
Skin ( )
Simple cuboidal epithelium
Kidney (epithelium of the proximal tubule)
Ovarian surface epithelium
Duct epithelium of sebaceous
Simple columnar epithelium
Tubuloacinar glands ()
Tubuloalveolar glands in( )
Tubuloalveolar glands in mucus glands (Brunner glands in the duodenum)
Submucosa of the
Fetal bone (woven/fibrous bone)
Mature bone (secondary/lamellar bone)
The following sections will provide examples of these specific organ tissues:
- Organs of the circulatory system
- Respiratory tract and lungs
- Blood and hematopoiesis
- Lymphoid organs
- Digestive system
- Accessory organs of the digestive tract
- Kidneys and the urinary tract
- Female reproductive organs
Slides of fetal tissue can be found in both the individual organ sections and a separate section onto enable quick comparison of fetal and adult tissues in the anatomical context as well as provide to easy reference in the embryological context.
Skin with skin appendages
There are two types of skin: and glabrous (hairless) skin. Hairy skin is less keratinized than glabrous skin and contains all types of ( , , , , and ). In contrast, glabrous skin is highly keratinized and only contains .
