Cells
epithelial, connective tissue (adipose), supportive tissue (cartilage/bone), muscle tissue
Cell types (7)
Simple squamous Simple cuboidal Simple columnar Stratified squamous Stratified columnar Pseudo stratified columnar Transitional
Simple squamous (location)
lung, kidney, liver
Stratified (location)
skin, rumen of cow
Transitional (location)
urogenital tract only
Epithelial
covering or bordering body or organ, cell free surface contacts environment, connected to underlying tissue by a basal membrane
Epithelial cell types
squamous, stratified, transitional, glandular
Simple squamous epithelium
lung, kidney, glands
Exocrine glands
merocrine, apocrine, holocrine
Glandular epithelium
produces secretions- proteins, lipids, carbohydrates
Matrix
Fibers (collagen, glycosaminoglycans, hyaluronic acid), amorphous group substance
Connective tissue
connective tissue proper, cartilage, bone, blood
Adipose tissue
energy storage, temperature insulation
Supportive tissue
cartilage, bone
Cartilage
elastic (ear), hyaline (joints), fibrous (intervertebral)
Elastic cartilage
elastic fibers (structural support) - ear, larynx, trachea
Hyaline cartilage
provides joint movement, cushions movements, no blood vessels
Fibrous cartilage
coarse collagenous fibers (intervertebral discs, meniscus)
Bone cells
mesenchymal cells, osteoblasts, osteocytes, osteoclasts
Osteoblasts
Store Ca++, new bone formation
Osteoclasts
Eat away bone, multinucleated cells, brush border, resorption lacunae, acid hydrolyses pH decreases, bone resorption, bone remodeling
Types of bone
woven, lamellar
Woven bone
Large lacunae, random arranged; collagen fibers in random pattern
Lamellar bone
cells and collagen in an orderly fashion
