cells and tissues Flashcards
simple epithelium
one layer of cells
stratified epithelium
multiple layers of cells
squamous epithelium
flat floor-tile-like cells
cuboidal epithelium
cubic cells
columnar epithelium
elongated, column-like cells
transitional epithelium
stretchy cells that can expand
keratin
form the tissues of hair, nails, and outer layer of skin
epithelial tissue
found throughout the body and covers organs
collagen fibers
thick and strong, give the tissue strength and anchor cells together
elastic fibers
they provide elasticity and resilience to tissues
reticular fibers
highly branched and delicate
loose fibrous connective tissue
binds skin to underlying organs and fills spaces between muscles
adipose tissue
stores and releases fats and lipids
reticular connective tissue
provides support and forms a stroma
cartilage
flexible connective tissue that keeps joint motion fluid
bone
gives strength and structure to the bones
connective tissue
compromises most of the body and is the most tissue by weight
muscle tissue
shorten or contract to move body parts
skeletal tissue
is striated, voluntary movement, many nuclei
smooth tissue
not striated, involuntary, one nucleus
cardiac tissue
striated, involuntary, one nucleus
nervous tissue
found in the brain, spinal cord, neurons
neurons
