    • Epithelial Tissue
      • Epithelial tissue covers the whole surface of the body.
      • It is made of closely packed cells that are arranged in one or more layers.
      • They are divided into two groups, simple and stratified.
      • Epithelial tissues duties are those of secretion, absorption, sensation and protection.
      Home Epithelial Tissue Credits
    • Simple Squamous
      • Cells flattened laterally with a sparse cytoplasm.
      • Thin and permeable, this epithelium is located where filtration or exchanging of substances by rapid diffusion.
      Home Epithelial Tissue Simple Squamous Credits
    • Stratified Squamous
      • The most common form of stratified epithelia.
      • Composed of several layers that are thick and suited for protection of the body.
      • This epithelium is constantly damaged and is subject to regeneration often.
      • This epithelium covers your whole body and extends a short distance into each body opening.
      Home Epithelial Tissue Stratified Squamous Credits
    • Simple Columnar
      • Single layer of small closely packed cells, aligned in a row.
      • It lines all of the digestive tracts from the stomach to the rectum.
      • These cells absorb and secrete materials .
      • Display cilia on their surfaces that help them to move substances through the digestive tracts.
      Home Epithelial Tissue Simple Columnar Credits
    • PsuedoStratified Columnar
      • Cells lay on the basement membrane and only the tallest of them reach the free surface of the epithelium.
      • These cells are generally unspecialized and give rise to taller cells.
      • They do absorb and secrete substance like the simple columnar cells.
      Home Epithelial Tissue PsuedoStratified Columnar Credits
    • Simple Cubiodal
      • Single layer of cells as tall as they are wide.
      • The spherical nuclei stain darkly, which makes them look like beads.
      • These cells primary duties are secretion and absorption.
      • This form of epithelium is found mainly in the smallest ducts of glands and also in the kidney tubules.
      Home Epithelial Tissues Simple Cuboidal Credits
    • Stratified Cuboidal
      • A epithelium that is found rarely in the body.
      • It is found mainly in ducts and some of the larger glands.
      • It usually consists of two layers of cuboidal cells.
      • This type of epithelial is found in transitional area between two other types of epithelia.
      • Its only apical layers of cells are columnar.
      Home Epithelial Tissue Stratified Cuboidal Credits
    • Transitional Epithelium
      • Forms linings of the urinary organs, which stretch as they fill with urine.
      • The apical cells vary in appearance and depending degree of the organs distension.
      • When the organs are full of urine the cells go from about six layers to three.
      • The ability for these cells to change form allows a greater volume of urine to flow through to tube like organ.
      • In the bladder it allows more urine to be stored.
      Home Epithelial Tissue Transitional Credits
    • Nervous Tissue
      • This is the main component in the nervous system.
      • It connects the brain, spinal cord, and the nerves.
      • These regulate our body and control our functions.
      • Neurons, which are common in nervous tissue, are specialized nerve cells that generate and control nerve impulses.
      • The branches and webs that form nervous tissue are one of the most important items in our body.
      Home Nervous Tissue Credits
    • Muscle Tissue
      • Tissue that has the ability to contract and pull in order to conduct the desired movements.
      • Muscle tissue is characterized by both voluntary and involuntary and then striated or smooth
      • From these classifications three main classes of muscle tissue come forth. The three classes are smooth involuntary, striated voluntary, and striated involuntary.
      Home Muscle Tissue Credits
    • Skeletal
      • Tissue put in connective tissue sheets that are attached to the bones from the skeleton.
      • Theses types of muscle form the flesh of the body.
      • As these muscles contract, they pull on bones or skin causing the body to move.
      • Skeletal muscles are long, cylindrical cells that contain an abundance of nuclei.
      Home Muscle Tissue Skeletal Credits
    • Smooth
      • The smooth muscle cells, as individuals are spindle shaped and the have one centrally located nucleus.
      • Smooth muscle cells are found primarily in the walls of hollow organs such as digestive tract and urinary tract organs.
      • It contracts to squeeze substances through these types of organs.
      • It contracts in intervals of contracting then relaxing.
      Home Muscle Tissue Smooth Credits
    • Cardiac
      • Found in the wall of the heart.
      • As this muscle contracts it pumps blood through blood vessels to all parts of the body.
      • Cardiac muscles although the same as skeletal muscles in ways they also differ.
      • Cardiac cells are uninucleate and are branching cells that fit together tightly at specific points.
      Home Muscle Tissue Cardiac Credits
    • Connective Tissue
      • Class of tissue that is mainly an exclusion of certain tissues. It is not a definite definition.
      • Duties are mainly structure and support.
      • It is identified commonly by its characteristic of non-living tissue.
      Home Connective Tissue Credits
    • Hyaline
      • Hyaline or Gristle the most common type of cartilage in the body.
      • It contains large amounts of collagen fibers.
      • The matrix of this substance appears amorphous and glassy.
      • Hyaline provides stringy pads that absorb compression at the joints.
      • A majority of the embryonic skeleton is formed of hyaline before the bone is formed.
      Home Connective Tissue Hyaline Credits
    • Fibrocartilage
      • Perfect structural intermediate between hyaline cartilage and dense regular connective tissue.
      • It has rows of chondrocytes alternating with rows of thick collagen fibers.
      • This allows this type of cartilage to be compressible and resist tension well.
      • It is found where strong support and the ability to withstand great force.
      Home Connective Tissue Fibrocartilage Credits
    • Elastic
      • Almost identical to hyaline cartilage.
      • This contains many more elastin fibers than in hyaline cartilage.
      • Cartilage found where extreme flexibility is needed.
      • It also forms the structure for the outer ear and the epiglottis.
      Home Connective Tissue Elastic Credits
    • Dense Regular
      • One variety of dense connective tissues, all of which have fibers as their predominant element.
      • Dense regular connective tissues contain closely packed bundles of collagen fibers running in the same direction, parallel of the direction of the pull.
      • These white, flexible fibers with great resistance to tension are crowded between the collagen fibers are rows of fibroblasts that continuously manufacture the fibers and scant ground substance.
      • This type of tissue has fewer cells than other fibroblasts and is poorly vascularized.
      Home Connective Tissue Dense Regular Credits
    • Dense Irregular
      • The same structural elements as the regular variety.
      • The bundles of collagen fibers are much thicker and they are arranged irregularly.
      • This type of tissue is in sheets that are formed to deal with tension that is created in many different directions.
      Home Connective Tissue Dense Irregular Credits
    • Loose Reticular
      • Resemble areolar tissue but the only fibers in its matrix are reticular.
      • These fibers lie scattered and are widely distributed in the body.
      • The cells are found in the lymph nodes, the spleen, and bone marrow.
      Home Connective Tissue Loose Reticular Credits
    • Loose Adipose
      • Similar to areolar tissue in structure and function but its nutrient storing ability is much greater.
      • The matrix of this cell is scanty and the cells are packed closely together.
      • A form of oil occupies the cells volume and displaces the nucleus to one side of the cytoplasm.
      • These cells can become some of the largest cells in the body.
      • Adipose tissue is richly vascularized and it has high metabolic activity.
      Home Connective Tissue Loose Adipose Credits
    • Loose Areolar
      • Shared by some of the other connective tissues, its duty is to support, bind and hold bogy fluids.
      • It also functions to defend the body against infection and storing nutrients.
      • This type of tissue is made obvious by its loose arrangement of its fibers.
      Home Connective Tissue Loose Areolar Credits
    • Blood
      • Bodily fluid found within blood vessels and it is the most atypical connective tissue.
      • Although it doesn’t connect things in your body it does produce mesenchyme and it consists of blood cells.
      • Blood consists of a matrix called blood plasma, which carries the blood cells.
      • Blood has a wide variety of cells. The cells that are most common in blood are red blood cells, and scattered white blood cells.
      • Blood functions as a transport for the cardiovascular system, carrying nutrients, wastes, respiratory gases, and many other substances.
      Home Connective Tissue Blood Credits
    • Bone
      • Osseous tissue has an outstanding ability to support and protect body structures and functions.
      • Bones also provide areas for blood cells to synthesize and fat to store.
      • Bones matrices are that of cartilage but much harder and rougher
