Tissue Identification
What is Simple Squamous Epithelium?
A single layer of flat, scale-like cells ideal for rapid gas diffusion.
What are endocrine glands?
Ductless glands that secrete hormones directly into the bloodstream.
The primary cell responsible for producing collagen fibers in connective tissue.
Fibroblasts
A single layer of tall cells with oval nuclei lined up near the base, commonly lining the digestive tract.
Simple columnar epithelium
What are exocrine glands?
Glands that release their secretions through ducts onto epithelial surfaces.
What are Macrophages?
Tissue-resident immune cells that engulf cellular debris and bacteria via phagocytosis.
Stratified Squamous Epithelium
A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane.
What are Mucous Cells?
These cells produce a pale-staining, thick glycoprotein fluid used for lubrication.
Granule-filled connective tissue cells that release histamine during allergic and inflammatory reactions.
Mast Cells
What is Simple Cuboidal Epithelium?
Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.
What are serous cells?
Secretory cells that produce a thin, enzyme-rich watery fluid.
