epithelium

forms membrane

muscle

allows for movement of limbs and for organ movements within the body

nervous

uses electrochemical signals to carry out its functions

connective

supports and reinforces body organs

epithelium

cells of this tissue may absorb and/or secrete substances

nervous

basis of the major controlling system of the body

muscle

it’s cells shorten to exert force

epithelium

forms endocrine and exocrine glands

connective

surrounds and cushions body organs

connective

characterized by having large amounts of extracellular material

muscle

allows you to smile, grasp, swim, ski, and throw a ball

connective

widely distributed; found in bones, cartilage and fat despots

nervous

forms the brain and spinal cord

six major functions of epithelium

protection, absorption, secretion, filtration, discussion, osmosis

special characteristics of epithelium

avascular, regenerate, support by connective (areolar) tissue, cells fit closely together

exocrine

duct from this gland type carries secretions to target organ or location

endocrine

examples are the thyroid and adrenal glands

endocrine

glands secrete regulatory hormones directly into blood or lymph

exocrine

the more numerous of the two types of glands

neither

duct from ovary that carries ovum (egg) to uterus

exocrine

examples are the liver, which produces bile, and the pancreas, which produces digestive enzymes

dense regular tissue

parallel bundles of collagenic fibers provide strength; found in tendons

adipose

stores fat

dense irregular connective

the skin dermis

ossetian (bone) tissue

hardest tissue of our “skull cap”

areolar

composes the basement membrane; surrounds and cushions blood vessels and nerves; its gel like matrix contains all categories of fibers and many cell types

hyaline

forms the embryonic skeleton; covers surfaces of bones at joint; trachea

adipose

insulates the body

hyaline

firm, slightly rubbery matrix; milky white and glassy in appearance

osseous (bone) tissue

cells are arranged in concentric circles around a nutrient canal; matrix is hard due to calcium salts

fibrocartilage

contains collagenous fibers; found in intervertebral discs

reticular connective tissue

makes supporting framework of lymphoid organs

elastic cartilage

found in external ear and auditory tube

blood

provides the medium for nutrient transport throughout the body

collagen fibers

tough protein fibers that resist stretching or longitudinal tearing

matrix (ecm)

composed of ground substance and structural protein fibers

ground substance

composed of glycoproteins and water binding glycosaminoglycans

reticular fiber

fine, branching protein fibers that construct a supportive network

ground substance

the medium through which nutrients and other substances diffuse

elastic fibers

randomly coiled protein fibers that recoil after being stretched
