Attached surface is bound to the basement membrane or BL
Name 4 general types of tissues
Epithelial, Connective, Muscle, Neural
Primary Function of Epithelial Tissue
Protection, others include absorption and secretion
2 Classifications of Epithelial Tissue
1. Number of Cell layers (simple,stratified epithelium) 2. Shape of Cells (squamous, cuboidal,columnar)
Simple Squamous Epithelium
Single layer of broad, flat cells, body's most delicate epithelium, located where absorbtion or diffustion takes place, (smooth) lining of the heart, blood vessels, and ventral body cavities
Stratified Squamous Epithelium
located where mechanical stress is severe, top layer of skin & lining esophagus and mouth, protect against abrasion, pathogens and chemical attacks
Simple Cuboidal Epithelium
Located in kidney tubules. Provide limited protection, secretion and absorption
Stratified Cuboidal Epithelium
RAREst of all epithelium, lines some sweat gland ducts, Provides protection, secretion and absorption
Transitional Epithelium
Multiple layers of cells tha permit expansion and recoil after stretching. Located in bladder.
Simple Columnar Epithelium
Nuclei elongated, have microvilli, line stomach, intestines and tubes. Protection, secretion,absorption
Pseudostratified Ciliated Columnar Epithelium
Appears layered, but all attached to basal lamina, shapes of nuclei vary, have cillia at top, located in resporatory track, trachea, bronchi, parts of male reproductive tract
stratified Columnar Epithelium
rare, Only the superficial layer appears illongated, located in the urethra, salivary glands, pharynx, epiglottis
