Study Notes
Tissues
- Tissues are formed when similar cells with similar functions come together.
- There are four main tissue types: epithelial, connective, muscle, and nervous.
Epithelial Tissues
- Cover surfaces, line internal organs and make up glands.
- Cells are closely linked, forming a sheet-like structure.
- Classified based on cell shape:
- Squamous (flat and scale-like)
- Cuboidal (cube-shaped)
- Columnar (column-like)
- Transitional (stretchy and variable in shape)
- Classified by cell arrangement:
- Simple squamous: Single layer of flattened cells, nuclei are flattened discs.
- Simple cuboidal: Single layer of cube-shaped cells, round nuclei.
- Simple columnar: Single layer of elongated cells, elongated nuclei.
- Stratified squamous: Multiple layers of same cell type, flatten as they move outwards.
- Stratified cuboidal: 2-3 layers of cubed cells.
- Stratified columnar: Multiple layers of columnar or cubed cells.
- Pseudostratified columnar: Single cell layer, appears layered because nuclei are at different levels.
- Transitional: Changes appearance based on tension.
- Glandular: Specialized cells, produce and secrete substances into ducts or body fluids, found in glands.
- Functions:
- Physical protection (against external and internal abrasion)
- Absorption (intestinal absorption)
- Filtration (tracheal filtration)
- Excretion (renal excretion, sweating)
- Sensation (ear, skin, nose, tongue sensation)
- Specialized secretion (hormones, enzymes)
- Permeability (kidneys, lungs)
Connective Tissues
- Most common tissue type.
- Found in organs, bones, nerves, muscles, and skin.
