Epithelial Tissue

• Surface/ Lining layer

• Cell close together

• sits on the basement membrane

• Simple: One layer

• Stratified: More than one layer

Squamous Epithelium

Flat

Cuboidal epithelium

Square

Columnar Epithelium

Rectangular

Simple Squamous Epithelium location, name of space in between, look, parts

Location: Lining of blood vessels

Space: Airsac

Look: Looks like many connections and lines

Parts: Nucleus, Cell membrane, cytoplasm

Simple cuboidal Epithelium location, base of tissue, part of cell, type, and look

Location: Lining of kidney

Base: Basement membrane

Simple Columnar Epithelium w/microvilli (non-ciliated) cell parts, other cells, location

Microvilli: Absorb nutrients

Goblet cells: Small base with mucus in the middle. has cytoplasm and a nucleus

Has a nucleus, a cell membrane, cytoplasm, microvilli, goblet cells, and basement membrane

Location: Lining of G.I. Tract

Pseudostratified Columnar epithelium parts, location, cell type

Looks layered but is not

• Has cillia, mucus, cytoplasm, cell membrane, nucleus

• Columnar cells or Goblet cells

• Location: Lining of airways

• Cilia move mucus

Transitional Epithelium cell type, location, parts of tissue

• Cell types: Stratified cuboidal cells on bottom w/ columnar cells on top (pillow shape on top)

• Parts of tissue: basement membrane, cell membrane, nucleus, cytoplasm

• Location: Lining of urinary bladdar

Non-keratinized stratified squamous epithelium cell type, description, location, parts of cell,

• Cell Type: cuboidal at base, squamous at top

• Description: many layers, gradual change between cuboidal and squamous, cells alive on surface, moist

• Location: Lining of body openings

• Cell parts: Nucleus, cell membrane, cytoplasm, basement membrane

Keratinized stratified squamous epithelium location, description, cell type, location, parts of cell

• Description: Dry skin surface (Cutaneous body tissue) to protect from water loss. 2 zones. First zone deeper has flattening alive cells, second zone has very thin dead cells

• Location: Body surface

• Cell type: Squamous

• Parts of cell: Nucleus, cytoplasm, cell membrane, basement membrane, dead cells (surface), live cells (deeper layers)

Areolar Connective Tissue location, description, cell types and parts

• Description: Has thin and bent elastic fibers, as well as thick and straight collagen fibers

• Cell type: Fibroblast/ fibrocyte

• Cell parts: nucleus, collagen fibers, elasin fiber, matrix

Adipose (Fat, triglyceride) location, description, cell type and parts

• Location: Under epithelium, cushioning organs, between muscles

• Description: Looks like cotton balls, fat vacuole, little cytoplasm, clustered in tissue

• Cell Type: Adipocyte
