Unit 2: Tissues

4 types of tissues

muscular, epithelial, nervous, connective

3 types of muscle tissue

smooth, cardiac, skeletal

involuntary, nonstriated, uninucleated (muscle)

smooth

uninucleated, striated, involuntary (muscle)

cardiac

multinucleated, striated, voluntary (muscle)

skeletal

converts stimuli to impulses and passes them (nervous)

neurons

supports and protects neurons (nervous)

neuroglia

3 types of cells in connective tissue

fibroblast, macrophage, mast

contributes to tissue formation (connective)

fibroblast

destroys infectious organisms (connective)

macrophage

controls immune responses (connective)

mast

3 types of fibers in connective tissue

collagen, reticular, elastic

skin, muscle, and bone fibers (connective)

collagen

liver, bone marrow, lymphatic fibers (connective)

reticular

skin, tendon, ligament fibers (connective)

elastic

3 types of loose connective tissue

areolar, reticular, adipose

holds organs in place, made of elastic and reticular fiber (connective)

areolar

supports bone marrow, made of reticular fiber (connective)

reticular

provides energy, storage, insulation, made of collagen fiber (connective)

adipose

3 types of dense connective tissue

dense regular, dense irregular, elastic

stucture, made of collagen fiber (connective)

dense regular

strength, made of collagen fiber (connective)

dense irregular

fix stretched fibers, made of elastic fiber (connective)

elastic

3 types of specialized connective tissue cartilage

hyaline, elastic, fibro

structure cartilage in joints (connective)

hyaline

flexible cartilage, in nose, ear, larynx (connective)

elastic

cushion cartilage in between joints and muscles (connective)

fibro

types of epithelial tissue

squamous, cuboidal, columnar, transitional, glandular

stratified tissue that swells to store liquid, looks like smushy cubes (epithelial)

transitional

group of cells that secrete fluids (epithelial)

glandular epithelium

3 types of exocrine secretion (epithelial)

merocrine, apocrine, holocrine

exocytosis (epithelial)

merocrine

cell pinches off with secretion (epithelial)

apocrine

cell ruptures and spills secretion in ducts (epithelial)

holocrine

diffusion to secrete fluids (epithelial)

endocrine secretion
