Epithelial tissue - ANS -cells arranged in sheets -have an apical (free) side and a basal side (attached to basement membrane) -covers exposed surfaces of body -lines internal passageways + organs -forms endocrine + exocrine glands 3. Epithelial cell arrangement - ANS -Simple = 1 layer -Stratified = multiple layers -Pseudostratified = column shaped multiple layers 4. Epithelial cell shapes - ANS -squamous: thin and flat -cuboidal: cube-like -columnar: long, column-like 5. Simple squamous epithelium - ANS single layer of flattened cells Ex. Lines blood vessels 6. Simple cuboidal epithelium - ANS single layer of cube shaped cells Ex. Bronchioles in lungs 7. Simple columnar epithelium - ANS Made up of a single layer of tall cells that fit closely together Ex. Female reproductive system 8. Stratified squamous epithelium - ANS Outer layer of skin Ex. Outer layer of skin 9. Transitional epithelium - ANS urinary bladder, stretches and retracts Ex. Urinate bladder 10. Epithelial glands - ANS merocrine, apocrine, holocrine 11. merocrine glands - ANS Secretions released from secretory vesicles via exocytosis at the apical surface 12. Apocrine glands - ANS Apical portion of cytoplasm becomes packed w/ secretory vesicles and is shed 13. Holocrine glands - ANS Secretions via loss of whole entire cell 14. Epithelial membranes - ANS cutaneous, mucous, serous 15. Mucous membranes - ANS Lubricate + protect inside of organs and cavities
