Epithelial Tissue <ul><li>Epithelial tissue covers the whole surface of the body. </li></ul><ul><li>It is made of closely packed cells that are arranged in one or more layers. </li></ul><ul><li>They are divided into two groups, simple and stratified. </li></ul><ul><li>Epithelial tissues duties are those of secretion, absorption, sensation and protection. </li></ul>Home Epithelial Tissue Credits
  3. 3. Simple Squamous <ul><li>Cells flattened laterally with a sparse cytoplasm. </li></ul><ul><li>Thin and permeable, this epithelium is located where filtration or exchanging of substances by rapid diffusion. </li></ul>Home Epithelial Tissue Simple Squamous Credits
  4. 4. Stratified Squamous <ul><li>The most common form of stratified epithelia. </li></ul><ul><li>Composed of several layers that are thick and suited for protection of the body. </li></ul><ul><li>This epithelium is constantly damaged and is subject to regeneration often. </li></ul><ul><li>This epithelium covers your whole body and extends a short distance into each body opening. </li></ul>Home Epithelial Tissue Stratified Squamous Credits
  5. 5. Simple Columnar <ul><li>Single layer of small closely packed cells, aligned in a row. </li></ul><ul><li>It lines all of the digestive tracts from the stomach to the rectum. </li></ul><ul><li>These cells absorb and secrete materials . </li></ul><ul><li>Display cilia on their surfaces that help them to move substances through the digestive tracts. </li></ul>Home Epithelial Tissue Simple Columnar Credits
  6. 6. PsuedoStratified Columnar <ul><li>Cells lay on the basement membrane and only the tallest of them reach the free surface of the epithelium. </li></ul><ul><li>These cells are generally unspecialized and give rise to taller cells. </li></ul><ul><li>They do absorb and secrete substance like the simple columnar cells. </li></ul>Home Epithelial Tissue PsuedoStratified Columnar Credits
  7. 7. Simple Cubiodal <ul><li>Single layer of cells as tall as they are wide. </li></ul><ul><li>The spherical nuclei stain darkly, which makes them look like beads. </li></ul><ul><li>These cells primary duties are secretion and absorption. </li></ul><ul><li>This form of epithelium is found mainly in the smallest ducts of glands and also in the kidney tubules. </li></ul>Home Epithelial Tissues Simple Cuboidal Credits
  8. 8. Stratified Cuboidal <ul><li>A epithelium that is found rarely in the body. </li></ul><ul><li>It is found mainly in ducts and some of the larger glands. </li></ul><ul><li>It usually consists of two layers of cuboidal cells. </li></ul><ul><li>This type of epithelial is found in transitional area between two other types of epithelia. </li></ul><ul><li>Its only apical layers of cells are columnar. </li></ul>Home Epithelial Tissue Stratified Cuboidal Credits
  9. 9. Transitional Epithelium <ul><li>Forms linings of the urinary organs, which stretch as they fill with urine. </li></ul><ul><li>The apical cells vary in appearance and depending degree of the organs distension. </li></ul><ul><li>When the organs are full of urine the cells go from about six layers to three. </li></ul><ul><li>The ability for these cells to change form allows a greater volume of urine to flow through to tube like organ. </li></ul><ul><li>In the bladder it allows more urine to be stored. </li></ul>Home Epithelial Tissue Transitional Credits
  10. 10. Nervous Tissue <ul><li>This is the main component in the nervous system. </li></ul><ul><li>It connects the brain, spinal cord, and the nerves. </li></ul><ul><li>These regulate our body and control our functions. </li></ul><ul><li>Neurons, which are common in nervous tissue, are specialized nerve cells that generate and control nerve impulses. </li></ul><ul><li>The branches and webs that form nervous tissue are one of the most important items in our body. </li></ul>Home Nervous Tissue Credits
  11. 11. Muscle Tissue <ul><li>Tissue that has the ability to contract and pull in order to conduct the desired movements. </li></ul><ul><li>Muscle tissue is characterized by both voluntary and involuntary and then striated or smooth </li></ul><ul><li>From these classifications three main classes of muscle tissue come forth. The three classes are smooth involuntary, striated voluntary, and striated involuntary. </li></ul>Home Muscle Tissue Credits
  12. 12. Skeletal <ul><li>Tissue put in connective tissue sheets that are attached to the bones from the skeleton. </li></ul><ul><li>Theses types of muscle form the flesh of the body. </li></ul><ul><li>As these muscles contract, they pull on bones or skin causing the body to move. </li></ul><ul><li>Skeletal muscles are long, cylindrical cells that contain an abundance of nuclei. </li></ul>Home Muscle Tissue Skeletal Credits
  13. 13. Smooth <ul><li>The smooth muscle cells, as individuals are spindle shaped and the have one centrally located nucleus. </li></ul><ul><li>Smooth muscle cells are found primarily in the walls of hollow organs such as digestive tract and urinary tract organs. </li></ul><ul><li>It contracts to squeeze substances through these types of organs. </li></ul><ul><li>It contracts in intervals of contracting then relaxing. </li></ul>Home Muscle Tissue Smooth Credits
  14. 14. Cardiac <ul><li>Found in the wall of the heart. </li></ul><ul><li>As this muscle contracts it pumps blood through blood vessels to all parts of the body. </li></ul><ul><li>Cardiac muscles although the same as skeletal muscles in ways they also differ. </li></ul><ul><li>Cardiac cells are uninucleate and are branching cells that fit together tightly at specific points. </li></ul>Home Muscle Tissue Cardiac Credits
  15. 15. Connective Tissue <ul><li>Class of tissue that is mainly an exclusion of certain tissues. It is not a definite definition. </li></ul><ul><li>Duties are mainly structure and support. </li></ul><ul><li>It is identified commonly by its characteristic of non-living tissue. </li></ul>Home Connective Tissue Credits
  16. 16. Hyaline <ul><li>Hyaline or Gristle the most common type of cartilage in the body. </li></ul><ul><li>It contains large amounts of collagen fibers. </li></ul><ul><li>The matrix of this substance appears amorphous and glassy. </li></ul><ul><li>Hyaline provides stringy pads that absorb compression at the joints. </li></ul><ul><li>A majority of the embryonic skeleton is formed of hyaline before the bone is formed. </li></ul>Home Connective Tissue Hyaline Credits

Loose Reticular <ul><li>Resemble areolar tissue but the only fibers in its matrix are reticular. </li></ul><ul><li>These fibers lie scattered and are widely distributed in the body. </li></ul><ul><li>The cells are found in the lymph nodes, the spleen, and bone marrow. </li></ul>Home Connective Tissue Loose Reticular Credits
  22. 22. Loose Adipose <ul><li>Similar to areolar tissue in structure and function but its nutrient storing ability is much greater. </li></ul><ul><li>The matrix of this cell is scanty and the cells are packed closely together. </li></ul><ul><li>A form of oil occupies the cells volume and displaces the nucleus to one side of the cytoplasm. </li></ul><ul><li>These cells can become some of the largest cells in the body. </li></ul><ul><li>Adipose tissue is richly vascularized and it has high metabolic activity. </li></ul>Home Connective Tissue Loose Adipose Credits
  23. 23. Loose Areolar <ul><li>Shared by some of the other connective tissues, its duty is to support, bind and hold bogy fluids. </li></ul><ul><li>It also functions to defend the body against infection and storing nutrients. </li></ul><ul><li>This type of tissue is made obvious by its loose arrangement of its fibers. </li></ul>Home Connective Tissue Loose Areolar Credits
  24. 24. Blood <ul><li>Bodily fluid found within blood vessels and it is the most atypical connective tissue. </li></ul><ul><li>Although it doesn’t connect things in your body it does produce mesenchyme and it consists of blood cells. </li></ul><ul><li>Blood consists of a matrix called blood plasma, which carries the blood cells. </li></ul><ul><li>Blood has a wide variety of cells. The cells that are most common in blood are red blood cells, and scattered white blood cells. </li></ul><ul><li>Blood functions as a transport for the cardiovascular system, carrying nutrients, wastes, respiratory gases, and many other substances. </li></ul>Home Connective Tissue Blood Credits
