SIMPLE SQUAMOUS SIMPLE CUBOIDAL SIMPLE COLUMNAR EPITHELIAL EPITHELIAL EPITHELIAL - Scale like; cheek - Box like; Kidney - Column like; SIMPLE EPITHLIAL cells, lungs, blood Tubules Digestives, -Single Layer vessels Intestine, Basal, -ASP Nucleus PSEUDOSTRATIFIED COVERING AND LINING COLUMNAR Respiratory Tract – EPITHELIAL Trachea - Protect - Surface epithelium - Fake Layer – Cilia- movement - Irregular Shape Gablet Cells - Mucus STRATIFIED TRANSITIONAL STRATIFIED CUBOIDAL STRATIFIED EPITHELIAL EPITHELIUM EPITHELIAL COLUMNAR STRATIFIED - Change in EPITHELIAL SQUAMOUS - Protective Shape – EPITHELIAL Tissue - Secretion and Apical EPITHELIAL - Skin - Sweat Gland, Protection; Cells mammary Male Urethra - Urinary TISSUE Gland, Bladder Salivary ENDOCRINE GLAND - Ductless Glandular Epithelium Ex. Thyroid, Sweat, - Secretion of Pituitary, etc. substances - Hormones EXCOCRINE GLAND - Duct Ex. Sweat, milk, saliva LOOSE ADIPOSE RETICULAR CONNECTIVE -Fats storage AREOLAR - Mesh like TISSUE cell -Web-like -Insulation Fashion - Lymphatic - Shocks -Yellowish tissue absorption and Binding Tissue CONNECTIVE TISSUE PROPER - Fibroblast DENSE DENSE REGULAR CONNECTIVE CONNECTIVE TISSUE DENSE IRREGULAR CONNECTIVE TISSUE TISSUE - Parallel - Tensile Strength - Random direction - More collagen Ex. Ligaments – Bonse to Bone Ex. Dermis fibers. Tendons – Bone to muscle CONNECTIVE - - greater resistance to TISSUE stretch COLLAGEN - High tensile strength CONNECTIVE TISSUE FIBERS AND GROUND SUBTANCES ELASTIC FIBER - Elastic - Proteoglycans and Cell Adhesion RETICULAR FIBER – Soft organs Ex. Liver and Spleen Hyaline - embryonic Fibro Cartilage – CARTILAGE Skeleton, ribs Elastic – external ear Knee, jaw joints, and cartilage of nose, (auride), epiglottis intervertebral disc - Chondrocytes trachea, larynx SPECIALIZED BONE CONNECTIVE TISSUE - Hardest connective Tissue, - Protection, - Osteocytes LIQUID BLOOD - Plasma SOLID - Red Blood Cell - Erythrocytes - White Blood Cell - Leukocytes - Platelets - Thrombocytes Voluntary Tissue - muscle SKELETAL TISSUE - type of muscle that is primarily responsible for voluntary movements in the body. that is under conscious - FOR LOCOMOTION, FACIAL EXPERSSION, AND POSTURE control. MUSSLE CARDIAC TISSUE - muscle found exclusively in the heart. It TISSUE Involuntary Tissue - muscle is responsible for the heart's contractions, which pump blood throughout the body. types that operate without conscious control. SMOOTH TISSUE - type of involuntary muscle found throughout the body. It plays a key role in various automatic processes Dendrites: Axon: Cell Body (Soma): Branch-like A long, slender Axon Terminals: Contains the extensions projection that The endpoints of NERVE CELL - or neuron, is nucleus and that receive transmits electrical the axon that organelles. signals from impulses away from release the basic functional unit of Responsible other the cell body. neurotransmitters the nervous system.
