Four Primary Tissues Flashcards
Attached by nonliving basement membrane
Epithelial
Main glandular tissue
Epithelial
Cells reproduce rapidly (quick healing)
Epithelial
Function: produce and secrete substances
Found: glands - exocrine (salivary and sweat) & endocrine (hormones)
Glandular epithelium
Usually has no vascular tissue (no blood supply)
Epithelial
Cells packed tightly
Epithelial
Provides support, protection, framework, fills space, stores fat, produces blood cells, fights infection, helps repair tissue
Connective
Binds structures together
Connective
Most abundant tissue in your body
Connective
Composed of scattered cells with abundant intercellular tissue mix
Connective
Most have good blood supply
Connective
Cells can reproduce
Connective
Simple
Single layer
Stratified
Multiple layers
Cuboidal
Square
Found throughout the body - covers all surfaces
Epithelial
Columnar
Column (rectangular)
Squamous
Flat
Function: secretion and absorption
Found: kidney tubules, ducts, covering of the ovaries
Simple cuboidal
Function: diffusion and filtration
Found: air sacs in lungs, walls of tiny blood vessels (capillaries)
Simple squamous
Function: secretion and absorption
Found: digestive tract, uterus, ducts of many glands
Simple columnar
Function: secretion
Found: ducts of sweat glands and mammory glands
Stratified cuboidal
Single layer, uneven nuclei, layered appearance, CILIA
Found: lining air passages, and tubes in the reproductive system (including nasal cavity)
Pseudostratified columnar
Function: protection
Found: outer skin, esophagus, tongue, mouth
Stratified squamous
Stretchable
Blocks diffusion (no leaking)
Found in the urinary bladder
Transitional epithelium
Made up of ground substances and fibers
Connective
Three types:
Skeletal, cardiac, smooth
Muscular
Contract or shorten to cause movement
Muscular
Found only in the heart and is under involuntary control
Cardiac
Muscle tissue that is attached to the skeleton that makes gross body movement or changes facial expression
Skeletal muscle
Strong and flexible fibers
Collagenous
Found in the lining of certain organs and it either dilates or constricts to control an organ
Smooth
Covers ends of joints, nose, and respiratory passages
Hyaline cartilage
Respiratory fibers
Elastic
Found in the ears and vocal cords
Elastic
Found in bone, ligaments, and tendons
Collagenous
Forms delicate thin membranes throughout the body
Loose connective tissue
Binds underlying organs to skin and each other
Loose connective tissues
Tendons- muscles to bones
Fibrous connective tissue
Ligaments- bones to bones
Fibrous connective tissue
Fat tissue
Adipose
Called chondrocytes / provides support and attachments / cushions bones
Cartilage
Cartilage
Dense connective
External ear and larynx
Elastic cartilage
Tough, shock absorbing
Fibrocatilage
Allows you to move, voluntary
Skeletal (striated)
Found only in the heart, involuntary
Cardiac
Blood tissue is…
Connective
Nerve impulses are received from other cells and enter the nerve cell here
Dendrite
Where the nerve impulses travel away from the nerve cell
Axon
Found in hollow organs (lining if the stomach, urinary bladder, lining if blood vessels)
Smooth
Main part of cell that contains organelles
Cell body
