Epithelial Tissue
- Ureter (stratified transitional epithelium)
Secretary Epithelia & Glands
-Appendix (simple tubular gland)
-Skin (sebaceous and sweat glands)
-Thyroid (concave endocrine gland)
-mucous cell
-serous cell
Epithelial tissue
1.Ureter (stratified transitional epithelium) OM
- Mention if lumen full of liquid (flattened cells)/empty (cylindrical cells)
- Mucosa = stratified transitional epithelium
- Lamina propria (no glands)
- Contains smooth muscle
Secretary epithelium and glands
2. Appendix OM (simple tubular gland)
-mucosa:
simple columnar epithelium
-glands: simple tubular glands (goblet cells -secrete mucus)
-lamina propria: lymphocytes- lymphoepithelial tissue
3. Skin OM (stratified squamous keratinized epithelium)
-Epithelium: stratified squamous keratinized epithelium
-Lamina Propria: hair follicles, sebaceous glands (no exudative duct so drain through hair
follicles) and sweat glands (apocrine)
Dermis: simple coiled tubular glands
-Connective tissue: loose and dense irregular connective tissue
-Adipocytes in adipose tissue
4.Thyroid OM (concave endocrine gland)
- Lobules: formed by septa, coming from fibrous capsule
, - Follicles: Simple cuboidal (in pic) or columnar epithelium (if over functions) filled
with colloid (store hormones as thyroglobulin but secreted into follicular cells when
needed and then absorbed into blood stream)
- Vessels
5. Trachea Mucous cell /goblet cell EM
-Mucous cell: numerous mucus vesicles in cytoplasm
-Ciliated cell: next to it, cilia can be seen in vertical cross section on its free surface
6. Serous cell EM
-abundant secretary granules
-endoplasmic reticulum
-visible nucleus
Connective Tissue
Tendon (regular dense connective tissue)
Subcutaneous Fat (irregular connective tissue and adipose tissue)
Fibroblast EM
Fibrocyte EM
1.Tendon (dense regular connective tissue) OM
-dense regular connective tissue
-longitudinal section of tendon:
parallel collagen fibers, sparse fibroblasts, fibrocytes (nuclei is thin and elongated)
-adipose tissue
2.Subcutaneous tissue (irregular connective tissue and adipose tissue)
-Adipose tissue: separated into lobes of groups of adipocytes by septa of irregular
connective tissue
-Collagen fibers have different directions
- collagen fibers are visible as transverse and elongated cross sections in sample
3.Fibroblast Collagen fibers EM
-Fibroblast nucleus
-Collagen fibers (outside cytoplasm) in elongated and transverse section
-Mitochondria
4.Fibrocyte Collagen fibers
- Ureter (stratified transitional epithelium)
