Histology

Single layer (simple) of very thin, flattened cells (squamous). Function: diffusion and filtration. Found in air sacs of lungs, walls of capillaries.

Single layer, cube-shaped cells. Function: Secretion and absorption. Found: Lining of kidney tubules, ducts of glands, covering surface of ovaries

single layer, elongated cells with their nuclei in about the same position in each cell (usually near the basement membrane). Protection, secretion, absorption.Found in the lining of digestive tract and uterus
- contains scattered goblet cells functioning in the secretion of mucus
- some columnar cells (involved in absorption) have tiny finger-like processes called microvilli (increases surface area)

Appear "stratified" but really a single layer with nuclei at various levels giving the appearance of layers. Usually ciliated (tiny, hair-like projections for sweeping materials along a surface). Contains goblet cells.- Function: secretion and cilia-aided movement
- Location: lining air passages like the trachea and tubes of the reproductive system

Muli-layered, squamous cells. Thicker tissue.
Functions in protection. Found lining body cavities like the mouth and outer layer of skin

thick, layered cuboidal cells. "Stretchable" tissue, also forms barrier to block diffusion. Found: lining of urinary bladder.

The cells (dark spots within the tissue) are called fibroblasts (fibro= fiber, blast= to make or create). These are the cells responsible for secreting the fibers present. The larger fibers (typically pink) are called collagen fibers. The small black fibers are elastic fibers. Collectively, the fibers and the rest of the substance surrounding the cells would be referred to as the matrix.

storehouse for nutrients, packed with cells and blood vessels

internal supporting framework of some organs, delicate network of fibers and cells evident cells (reticular cells) and the large, dark fibers (reticular fibers).

Tendons and ligaments, regularly arranged bundles packed with fibers running same way for strength in one direction. orderly fibers running throughout the tissue. These fibers are collagen fibers.Embedded within the fibers are the fiber-producing cells called fibroblasts.

Skin, organ capsules, irregularly arranged bundles packed with fibers for strength in all directions.fibroblasts

Presence of elastic fibers within the matrix of the tissue.

Have a smooth, amorphous (no form) matrix with cells suspended within it. The matrix is compact fibers of collagen and the cells producing the matrix are called chondrocytes. They are contained within tiny chambers called lacunae (“little lakes”).

Is found forming the intervertebral discs in the spinal column, the pubic symphysis, and in the discs of the knee. While its composition is similar to that of hyaline cartilage, it is not as firm and possesses more noticeable collagen fibers.The cells present are still referred to as chondrocytes and are found in lacunae in this tissue as well.

Arranged in concentric ring structures called osteons. In the center of each ring is a structure called a Haversian canal. This canal carries blood vessels through the bone to nourish the cells embedded within the tissue. Around the Haversian canal, rings of bone tissue from called lamellae. Within these rings are the chambers called lacunae that would contain the cells. The cells themselves are called osteocytes (osteo= bone, cyte= cell). Radiating out from the lacunae are tiny channels that allow interaction of the cells with the blood supply. These tiny channels are called canaliculi.
