(Stratified columnar epithelium)
Connective tissue
- Wide variety of forms in the body including blood, bone, cartilage, and lymph
- Found throughout the body
- Common theme in that they contain cells that are within a matrix
- In most cases the matrix is produced by the cells in the tissue
- Functions
- “Connecting” structures together (ie. ligaments and tendons)
- Transport (blood and lymph), body structure (bone, cartilage), and fat storage (adipose)
Connective Tissue Cells
- Different types of cells, depending on their location and function
- Common cells
- Those of the immune system (macrophages)
- Fibroblasts are a part of many connective tissues and are fairly unspecialized cells.
- Highly specialized
- Specific cells such as osteocytes (in bone), chondrocytes (in cartilage), adipocytes (in adipose), and reticulocytes (in reticular connective tissue)

Epidermis
Epidermis description
- A stratified squamous epithelium in which the upper layer of cells is keratinized (containing many tough keratin filaments)
Epithelial naming convention
- Named according to how many cell layers are in the epithelium and by the shape of the cells nearest the apical layer
- One layer of cells is called simple, whereas more than one layer is stratified
- Simple
- Squamous: cells that are flat
- Cuboidal: cube-shaped
- Columnar: column-shaped
- Stratified
- For stratified epithelia, the shape is named according to the uppermost (apical) layer
- For example in the stratified squamous epithelium, the top most layer is flattened (squamous), but often the lower layers appear more cuboidal
Epithelial surfaces
- Apical surface: “free” or facing an opening
- Basal surface: anchored to other tissues
Epithelial tissue functions
- Cover the surface of organs
- Line the inside of open cavities
- Form glands that produce secretions

(Hyaline cartilage)
Gland types & descriptions
- Sebaceous glands: Sebum on the hair shaft
- Sudoriferous glands: Produce sweat
- Ceruminous glands (skin of the ear canal): Produce a waxy substance called cerumen
