Nerve Cell

Microvilli - cellular extensions on epithelial cells in the lumen of thesmall intestine that increase surface area

Cilia - hairlike extensions

underlying tissues by a basement membrane composed of extracellular material containing protein fibers.

Simple Squamous Epithelium. Flat, pancake-shaped. Filters,& protects. Lines internal cavities, the heart, all capillaries & blood vessels, air sacs of the lungs

Simple Cuboidal Epithelium. Cube-shaped. Found in tubules of the kidney -absorbs; ducts of many glands - protects; & secretory portions of some glands -secretes.

Simple Columnar Epithelium. Column-like (tall) with a cylindrical nucleus at the base. Absorbs, protects, & secretes. Goblet cells exist within the simple columnar epithelial tissue. Goblet cells contain mucus.- Nonciliated: Lines the tubes of the digestive tract from the stomach to theanus. - Ciliated: Lines the uterine tube. Functions additionally in the movement of egg cells towards the uterus.

Stratified Squamous Epithelium. Inner layers are cuboidal or columnar; outer layers are flattened. Protect & repel water. Located in the skin, lines the mouth, throat, anal canal, & vagina

Inner layer of the epidermis

Outer layer of the epidermis.

Stratified Cuboidal Epithelium. Cuboidal. Protect. Located in the sweat glands, mammary glands, & salivary glands.

Stratified Columnar Epithelium. Column-like (tall). Protect & Secrete. Located in the eye, pharynx, & salivary glands

Stratified Transitional Epithelium. * Protects & accommodates fluctuations in volume of liquids in an organ. Located in the bladder, ureters, urethra, & prostate. *The shape of the cell changes. The cells appear to be cuboidal with a domed apex when the organ or the tube in which they reside is not stretched. When the bladder fills, the tissue actually compresses and the cells become stretched, and they appear to be flat, irregular, and squamous

Pseudostratified Columnar Epithelium. Looks layered but is not; single layer; all cells come in contact with the basement membrane (like alligator teeth). Protects & secretes.

Located in the membranous part of male vas deferens

• Pseudostratified Columnar Epithelium
• Ciliated: Line the trachea & upper respiratory tract. Functions additionally in the movement of mucus & debris in the trachea up towards the throat so that it cannot enter the lungs

• Pseudostratified Columnar Epithelium
• - Ciliated: Line the trachea & upper respiratory tract. Functions additionally in the movement of mucus & debris in the trachea up towards the throat so that it cannot enter the lungs

Nervous tissue is located in the brain, spinal cord, & nerves. Nervous tissue forms a communication network. Neurons carry signals by conducting electrical impulses, which control the glands and muscles in the body

Areolar Loose Connective Tissue. Lots of collagen fibers. Most predominant connective tissue in the body. Attaches the skin to the underlying tissue; fills the spaces between various organs - holds them in place, cushions & protects them; surrounds and supports the blood vessels.- mast cells contain chemicals involved in the body's defense system.(areol(-a) is Latin for “a little open space”)

2) Adipose Loose Connective Tissue. Fat cells. Large cells with fat-filled vacuoles; nucleus pushed to one side; very few fibers. Located beneath the skin, around the kidney and heart, and in the breast. Insulation, fat storage, cushioning, & protection

Reticular Loose Connective Tissue. Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are thin, branching structures. The fibers form a soft skeleton (stroma) to support the lymph nodes

Regular Dense (Fibrous) Connective Tissue. Example: tendons that attach muscle to bone. Predominantly collagen fibers. The collagen fibers in dense regular connective tissue are organized in a parallel fashion.

Comprises a large portion of the dermis. Predominantly collagen fibers. The collagen fibers in dense irregular connective tissue are not organized in a parallel fashion; they are “swirly”

Most of the skeleton of the mammalian fetus is composed of hyaline cartilage. As the fetus ages, the cartilage is gradually replaced by more supportive bone. In adults, hyaline cartilage is located in the end of the nose and in the rings in the walls of the trachea. The matrix appears as a smooth, solid, blue or pink-colored substance

Fibrocartilage Connective Tissue. Characteristic herringbone pattern. It is located in the pubic symphysis, which is in the middle of the left and right pubic bones. This tissue loosens during labor to aid in deliver

Elastic Cartilage Connective Tissue. Located in the outer ear, larynx, and epiglottis. Similar to hyaline cartilage but contains many yellow elastic fibers that make the matrix look more webbed.

Concentric circles (like tree rings). Located in the bones of the skeleton. Support & protection

Less dense, softer, & weaker than compact bone. It typically occurs at the ends of long bones

Lymph is made up largely of lymphocytes in a special fluid and is largely responsible for the immune system. Located in lymph nodes

Skeletal Muscle Tissue. Striated cells with multiple nuclei. Located in muscles attached to the skeleton. Voluntary (contraction requires conscious control). Functions in voluntary movement of the body

Cardiac Muscle Tissue. Branching striated cells, each with a single nucleus. Located in the walls of the heart. Involuntary (contraction does not require conscious control); functions in pumping blood.- intercalated discs bind fibers togethe

Smooth Muscle Tissue. Spindle-shaped, unstriated cells, each with a single nucleus. Located in walls of digestive tract & blood vessels. Involuntary. Functions in the movement of substances in body cavities
