BI231 Tissue Test

simple squamous epithelium

single layer of flattened cells, function is diffusion and filtration, location is air sacs of lungs, walls of capillaries

stratified squamous

cells at apical surface are flattened, lines the esophagus and forms the skin epidermis, found as a protective covering where friction is common

Stratified Squamous

basement membrane (basal lamina)

Layer of extracellular matrix attaches epithelia to underlying connective tissues

simple cuboidal epithelium

single layer of cube shaped cells with large, spherical central nuclei, function is limited protection, secretion, absorption, location is kidney tubules, ducts and secretory portions of small glands, ovary surface

stratified cuboidal epithelium

Function: protection

Location: Largest ducts of sweat glands, mammary glands, and salivary glands.

simple columnar epithelium

Cells shaped like bricks standing on end with nuclei at the base of the cell, function is secretion, absorption, protection, location is digestive tract

stratified columnar epithelium

Function: protection and secretion

Location: rare in the body; small amounts in male urethra and in large ducts of some glands

cartilage

A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together. Also used for shock absorption

hyaline cartilage

Most common type of cartilage; it is found on the ends of long bones, ribs, and nose. helps reduce friction between bones

connective tissue

A body tissue that provides support for the body and connects all of its parts

fluid connective tissue

specialized cells that circulate in a watery fluid containing salts, nutrients, and dissolved proteins; including blood and lymph

connective tissue fibers

collagen, elastic, reticular

connective tissue proper

loose connective tissue and dense connective tissue; including fibroblasts, adipose, mast cells, macrophages

loose connective tissue

areolar, adipose, reticular

tendons

A cordlike or bandlike mass of white fibrous connective tissue connects a muscle to a bone

Ligaments

A cord or sheet of connective tissue binding two or more bones at a joint

bone tissue

osseous tissue, osteocytes in lacunae, hard matrix full of calcium, Most rigid connective tissue, Internally supports body structures, very active tissue, heals much more rapidly than cartilage

smooth muscle

Involuntary muscle found in walls of hollow organs, no visible striations, one nucleus per cell, spindle-shaped cells

cardiac muscle

Involuntary muscle tissue found only in the heart, had intercalated disks where “branches” meet, striated, one nucleus per cell

skeletal muscle

A muscle that is attached to the bones of the skeleton and provides the force that moves the bones. Voluntary, produces gross body movements or facial expressions, striated, multinucleate, long, cylindrical, contains connective tissue and tendons

nervous tissue

A body tissue that carries electrical messages back and forth between the brain and every other part of the body, regulates the system, produces myelin, maintains ionic environment, location is brain, spinal cord, nerves

Neurons

a nerve cell; the basic building block of the nervous system, transmits nerve impulses

Transitional

Shape of cells depends upon the amount of stretching

Lines organs of the urinary system

Reticular connective tissue

A complex network of nerve fibers within a brainstem that arouses the cerebrum; a type of connective tissues that cross link and from a fine meshwork

Found in: Lymph nodes, Spleen, Bone marrow

Pseudostratified (ciliated) columnar

Single layer, but some cells are shorter than others

Often looks like a double layer of cells

Sometimes ciliated, such as in the respiratory tract

Elastic Cartilage

cartilage with abundant elastic fibers; more flexible than hyaline cartilage; provides elasticity, location is external ear and epiglottis

Areolar tissue

Most widely distributed connective tissue

Soft, pliable tissue like "cobwebs"

fibrous connective tissue with the fibers arranged in a mesh or net

Functions as a packing tissue

Simple

single layer

Apical

free surface

Simple Squamous

Bone

Fibrocartilage

Pads between vertebrae that are shock absorbers; make invertebral discs made of layers of collagen, compressible, contains fibrous bundles of collagen

Stratified

multiple layers

Blood

Cells surrounded by fluid matrix; fibers only visible in hemostasis

stratified squamous epithelium

pseudostratified ciliated columnar epithelium
