Tissue unit review (Chapter 4)

adipose tissue

functions are long term energy storage, cushioning, and insulation

simple squamous epithelium

single row of flat scale-like cells that line capillaries and air sacs in the lungs

stratified epithelium

tissue made of multiple cell layers; mainly found in areas of high friction

reticular

connective tissue made of bold fibers and primarily found in the liver and lymphatic organs

tissue

a group of cells working together for a common function

epidermis

outer skin layer made of stratified squamous epithelium

ligament

strong strip of dense regular connective tissue that holds and connects two bones together

tendon

strip of dense regular connective tissue that connects a muscle to a bone

nervous

general tissue type whose cells conduct electrical impulses

muscle

general tissue type whose cells contract and cause movement

basement membrane

deep border between epithelial and connective tissue; secretes sticky proteins to help hold together the different tissues

dense irregular tissue

connective tissue type made of disorganized fiber bundles; concentrated around organs

extracellular matrix

non-living glue like fibers and ground substance produced by connective tissue cells

basement membrane

sticky bottom border layer in between epithelial and connective tissue

osteocyte

bone cell which helps produce rings of solid calcified bone tissue

chondrocyte

cell which makes a spongy matrix characteristic of cartilage tissue

biopsy

surgical removal of a small piece of tissue for microscopic examination

dense regular connective tissue

tissue type of ligaments and tendons

epithelium

tissue found on organ surfaces and organ inner linings ; typically arranged in simple or stratified layers

secretion

the process to release chemical products from cells

aerolar tissue

the most common connective tissue type made of sticky crisscrossing fibers

histology

the study of tissues and their associated health problems

cilia

microscopic hairs lining the inner trachea and bronchiole tubes; typically found in pseudostratified columnar epithelium

blood

liquid connective tissue whose matrix is the plasma

cuboidal

epithelial cells that typically produce and secrete chemical products; normally shaped like a square box

desmosome

interlocking cytoskeleton connnections like "snapping" together two adjacent cells

gap junctions

microscopic tunnels for ion and small molecule transport between cells

adhesion belt

bands of dense proteins that connect between cells microfilaments; sort of like velcro strips between cells

lumen

space within a tubular part or organ, such as the space within a blood vessel or intestine

avascular

lacking blood vessels; such as cartilage and epithelial tissue
