Epithelial tissue
Epithelial tissue
A tissue type that covers external surfaces or lines internal cavities. It is classified as either membranous or glandular.
Membranous Epithelium
Membranous Epithelium
Epithelial tissue that forms layers on surfaces or lines cavities. It can be simple (one layer) or stratified (multiple layers).
Glandular Epithelium
Glandular Epithelium
Epithelial tissue that specializes in secretion. It can be either exocrine (secreting outwards) or endocrine (secreting into the blood).

Study Notes
Tissues of the Body
- Cells combine to form tissues, and tissues combine to form organs.
- Cells combine to form four primary tissues: epithelial, connective, muscle, and nervous tissue.
Epithelial Tissue
- Two types: surface (membranous) and glandular.
- Surface epithelia cover the external body surface or line cavities.
- Two types: simple and stratified.
- Glandular epithelia form exocrine and endocrine glands.
- Exocrine glands secrete into a body surface (e.g., sweat, salivary).
- Endocrine glands secrete hormones into the blood (e.g., pituitary, thyroid).
Membranous Epithelia
- Simple epithelium (one layer): associated with lubrication, absorption, or secretion.
- Simple squamous epithelium (e.g., lung alveoli)
- Simple cuboidal epithelium (e.g., renal tubules)
- Simple columnar epithelium (e.g., intestinal inner-surface)
- Pseudostratified columnar epithelium (e.g., trachea inner-surface)
- Stratified epithelium (multi-layers): associated with protection.
- Stratified squamous epithelium:
- Non-keratinized (e.g., esophagus)
- Keratinized (e.g., skin)
- Stratified cuboidal epithelium (e.g., ducts of sweat glands)
- Stratified columnar epithelium (rare, e.g., male urethra)
- Transitional epithelium (e.g., urinary bladder)
- Stratified squamous epithelium:
Connective Tissues
- Formed by cells and fibers in a ground substance.
- Cells: fibroblasts (fibers and ground substance), mast cells/macrophages/plasma cells (defense), and adipocytes (fat storage).
- Fibers: collagen, reticular, and elastic.
- Ground substance: glycosaminoglycans and proteoglycans.
- Three types:
- Connective tissue proper (loose and dense)
- Connective tissues with special properties (adipose, blood, lymph)
- Supporting connective tissues (bone and cartilage)
Muscle Tissue
- Consists of specialized cells that contract when stimulated.
- Three types of muscle tissue:
- Skeletal (voluntary), attached to skeleton.
- Cardiac (involuntary), in the heart.
- Smooth (involuntary), in the walls of hollow organs (viscera).
Nervous Tissue
- Contains specialized cells that conduct nerve impulses.
- Two types of cells:
- Neurons (conducting cells) transmit impulses from one body region to another
- Glial cells (non-conducting cells) support the neurons (e.g., astrocytes, oligodendrocytes)
