simple squamous epithelium
single layer of flat, scale-like cells found in the outer layer of the duodenum, visceral and parietal
peritoneum, alveoli of lungs, Bowman's capsule, and the endothelium of capillary walls.
simple columnar epithelium
single layer of long, column-shaped cells. Some produce mucous from goblet cells found within them.
Found in the inner layer of the duodenum and line digestive tracts.

simple cuboidal epithelium
single layer of cube-shaped cells found in the inner layer of nephric tubules of kidney and thyroid gland.
pseudostratified ciliated columnar epithelium (PCCE)
one layer of elongated cells found in the inner layer of trachea.
simple epithelia
single layer of cells
stratified epithelia
more than one layer of cells
,epithelial tissues
line the inside and outside of cavities
stratified squamous keratinized epithelium
has a dead, flaky, flattened cornified layer of cells called the stratum corneum
stratified squamous nonkeratinized epithelium
no dead layer present; found in the vagina, mouth, and esophagus.
stratified cuboidal epithelium
tissue that consists of two or more layers of cube-shaped cells, found in sweat gland ducts, pharynx, and
part of the epiglottis.
fibrous, bone, cartilage, blood
4 broad categories of connective tissues.
Loose (areolar)
Adipose
Reticular
Dense regular
Dense Irregular
5 subcategories of fibrous connective tissue
loose (areolar) fibrous connective tissue
found between other tissues and organs; superficial fascia surrounding blood vessels. It contains a
watery matrix with numerous collagenous and elastic fibers. Cells abundant also.
adipose connective tissue
padding at various points beneath the skin- in breasts and on digestive organs. Mostly comprised of
adipocytes with little matrix.
reticular connective tissue
Forms the inner framework, or stroma, of the spleen, lymph nodes, and bone marrow. It is mostly
comprised of reticular fibers and reticular cells. Plays a role in immunity.
dense regular connective tissue
Mostly comprised of densely packed collagen fibers with a few fibrocytes among fibers, tendons,
ligaments, and aponeuroses. They make a flexible, but strong connection. (tow strap)
dense irregular connective tissue
contains mostly loosely arranged collagen fibers, some elastic fibers and fibrocytes. Found in deep fascia,
dermis, scars, and capsule of kidney.
, connective tissue
A body tissue that provides support for the body and connects all of its parts. Contains non-living
components.
bone
yields support and protection and serves as a calcium reservoir. Has a calcified matrix and many collagen
fibers, comprised of osteons.
hyaline, elastic, fibrocartilage
3 subcategories of cartilage connective tissue.
hyaline cartilage
Most common type of cartilage; it is found on the ends of long bones, costal cartilages, tracheal rings,
larynx, part of nasal septum and bronchi.
elastic cartilage
cartilage with abundant elastic fibers; more flexible than hyaline cartilage. Found in epiglottis and
Eustachian tube.
fibrocartilage
cartilage that contains fibrous bundles of collagen, such as that of the intervertebral disks in the spinal
cord.
blood
consists of a liquid matrix (plasma) and formed elements (erythrocytes, leukocytes, platelets)
smooth, cardiac, skeletal
3 types of muscle tissue.
smooth muscle
taperd or spindle-shaped cells arranged in sheet-like layers. Abundant in hollow organ walls.
Uninucleate, non-striated.
cardiac muscle
Involuntary muscle tissue found only in the heart. Uninucleate (or rarely binucleate), branching cells,
striated.
skeletal muscle
attached to bones, striated, voluntary. Consist of myofibrils, striated, nuclei on surface of fibers.
neurons
large cells with axon(s), dendrites, and cell bodies (perikaryon or soma)
