Types of Tissues

Tissues

A collection of specialized cells and cell products that perform a specific function

Connective Tissue

One of the four primary tissues types; provides a structural framework for the body that stabilizes the relative positions of the other tissue types; includes cartilage, bone, and blood

Epithelial Tissue

Covers body surfaces, lines cavities and tubular structures, often needed for secretion and absorption

Simple Epithelium

Consists of a single layer of cells covering the basement membrane

Simple Squamous Epithelium

The cells are thin and flat, and the nucleus occupies the thickest portion of each cell

Simple Cuboidal Epithelium

Resemble little hexagonal boxes when seen in three dimensions, but in typical sectional view they appear square

Tendons

A collagenous band that connects a skeletal muscle to an element of the skeleton

Ligaments

Dense band of connective tissue fibers that attach one bone to another

Blood

The ground substance of this connective tissue is plasma

Cartilage

A connective tissue with a gelatinous matrix containing chondrocytes

Bone

A connective tissue consisting of living cells held in a rigid matrix of collagen fibers embedded in calcium salts.

Muscle Tissue

A tissue characterized by the presence of cells capable of contraction

Skeletal Muscle Tissue

Contractile tissue characterized by striated, voluntary muscle

Cardiac Muscle Tissue

Striated tissue characterized by intercalated disks

Smooth Muscle Tissue

is found in the walls of blood vessels; around hollow organs such as the urinary bladder; and in layers around the respiratory, circulatory, digestive, and reproductive tracts

Neural(Nervous)Tissue

Is specialized for the conduction of electoral impulses from one region of the body to another

Adipose Tissue

Connective tissue dominated by adipocytes; stores energy but is also metabolically/hormonally active

Extracellular Matrix

collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.

Dense Fibrous Tissue

mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.

Pseudostraified Columnar

type of epithelium that, though comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified epithelia.

Transitional Epithelium

type of tissue consisting of multiple layers of epithelial cells which can contract and expand. It is so named because of this function in the transition of degree of distension.

Stratified Columnar Epithelium

rare type of epithelial tissue composed of column shaped cells arranged in multiple layers. Stratified columnar epithelia are found in the conjunctiva of the eye, in parts of the pharynx, anus, the uterus, and the male urethra and vas deferens. It is also found in the lobar ducts in salivary glands. The cells function in secretion and protection.

Stratified Squamous Epithelium

onsists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.

Stratified Cuboidal Epithelium

type of epithelial tissue composed of multiple layers of cube-shaped cells. Only the most superficial layer is made up of cuboidal cells, and the other layers can be cells of other types.

glial cells

cells that support and protect neurons

RhoGAM

Used to prevent an immune response to Rh positive blood in people with an Rh negative blood type

Antigen

A protein that, when introduced in the blood, triggers the production of an antibody

antibody

A protein that acts against a specific antigen

Erythropoietin (EPO)

hormone secreted by the kidney to stimulate the production of red blood cells by bone marrow

stem cells

unspecialized cells that retain the ability to become a wide variety of specialized cells

Leukocytes

white blood cells, fight infection

Lymphocytes

The two types of white blood cells that are part of the body's immune system: B and T cells

serum

plasma without clotting factors

Plasma

liquid portion of blood that also includes clotting proteins

Platelets

thrombocytes; small fragments that are instrumental in forming a blood clot

hyaline cartilage

Most common type of cartilage; it is found on the ends of long bones, ribs, and nose; also called articular

elastic cartilage

cartilage with abundant elastic fibers; more flexible than hyaline cartilage; ears and nose

Type O blood

Also known as the universal donor

Type AB blood

Also known as the universal recipient

antibody

a highly specific protein molecule produced by the body that destroys or inactivates an antigen that has entered the body

Type A blood

This blood type produces B antibodies

Rh factor

Symbolized "D", this protein is present on some red blood cells and was first discovered in monkey species

Bone tissue

A type of connective tissue with a calcified, collagenous matrix

soma

the main cell body of a neuron

endothelium

simple epithelial tissue found lining the heart and blood vessels

RhoGAM injection

an immune serum that prevents a mother's blood from becoming sensitized to foreign antibodies from her fetus

Axon

the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands

osteon

the smallest function unit of bone

Haversian canal

Channels in bone that contain blood vessels and nerves

Canaliculi

Hairlike canals that connect lacunae to each other and the central canal in bone

ground substance

mostly water, this includes the basic components of connective tissue's "matrix"

fibroblast

most abundant cell type in connective tissue, secretes protein fibers and matrix into the extracellular space; critical for tissue repair
