Epithelial Tissue
Covers the body and its parts; lines various parts of the body; forms continuous sheets that contain no blood vessels; classified according to shape and arrangement. (1)
![Page 3: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/3.jpg)
Simple Squamous
Consists of only one layer of flat scale-like cells.
Substances can readily diffuse or filter through this type of tissue. (1)
![Page 4: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/4.jpg)
Stratified Squamous
Found in the lining of the vagina, mouth, and esophagus.
Free surface is moist and outer epithelial cells unlike those found in the skin do contain keratin. (1)

Transitional
Stratified tissue typically found in body areas such as the wall of the urinary bladder that are subjected to stress and tension changes. (1)

Simple Columnar
Composes a surface of the mucus membranes that line the stomach, intestines, uterus, uterine tubes, and parts of the respiratory tract. (1)
![Page 7: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/7.jpg)
Stratified Columnar
Has multiple layers of columnar cells only the most superficial cells are truly columnar in appearance.
Located in segments of the male urethra and in the mucus layer near the anus. (1)

Pseudostratified
Is found lining the air passages of the respiratory system and certain segments of the male reproductive system such as the urethra. (1)

Simple Cuboidal Composed of one layer of the cuboidal
cells resting on a basement membrane. Is seen in many types of glands and
their ducts. (1)
![Page 10: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/10.jpg)
Stratified Cuboidal
Serves as protective function and typically two or more rows of low cuboidal cells are arranged randomly over a basement membrane. (1)
![Page 11: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/11.jpg)
Glandular
Specialized for secretory activity. Unlike the single or layered cells of the
membranous epithelium cells typically found in protective covering or linings, glandular epithelial cells may function singly as unicellular glands, or they may function in clusters solid cords, or specialized folic ales as multicellular glands. (1)

Connective Tissue
One of the most widespread tissues in the body.
Found in or around nearly every organ of the body. (1)
![Page 13: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/13.jpg)
Loose Ordinary Fibrous
Also known as areolar It is loose because it is stretchable and
ordinary because it is one of the most widely distributed of all tissues. (1)
![Page 14: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/14.jpg)
Apidose
Differs from loose ordinary connective tissue mainly in that it contains predominantly fat cells and many fewer fibroblasts, macrophages, and mast cells. (1)
![Page 15: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/15.jpg)
Reticular
Three-dimensional web that is a reticular network.
Slender branching reticular fibers with reticular cells overlying them composed the reticular meshwork. (1)

Dense Regular Fibrous
Consists mainly of fibers packed densely in the matrix.
Contains relatively few fibroblast cells. (1)
![Page 17: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/17.jpg)
Dense Irregular Fibrous
The bundles of fibers are not arranged in parallel rows instead the fibers intertwine to form a thick mat of strong conductive tissue that can withstand stresses applied from any direction. (1)
![Page 18: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/18.jpg)
Bone
One of the most highly specialized forms of conductive tissue. (1)
![Page 19: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/19.jpg)
Hyaline Cartilage
The low amount of collagen in the matrix gives hyaline cartilage a shiny and translucent appearance.
Is found in the support rings of the respiratory tubes and covering the ends of bones that articulate at joints. (1)

Fibrocartilage
Strongest and most durable type of cartilage.
Matrix is rigid and filled with a dense packing of strong white collagen fibers. (1)
![Page 21: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/21.jpg)
Elastic Cartilage
Contains few collagen fibers but large numbers of very fine elastic fibers that give the matrix a high degree of flexibility.
Found in the external ear and in the voice box. (1)
![Page 22: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/22.jpg)
Blood
Most unusual connective tissue because it exists in a liquid state and contains neither ground substance nor fibers. (1)
![Page 23: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/23.jpg)
Muscle
Specialized tissue type that produces movement. (1)
![Page 24: Tissues & muscles](https://reader034.fdocuments.us/reader034/viewer/2022051412/5487b7a5b4af9faf0d8b5500/html5/thumbnails/24.jpg)
Skeletal
Composes muscles attached to bones; these are the organs that we think of as our muscles. (1)

Smooth
Sometimes called visceral muscle tissue, is found in the walls of the viscera organs (1)

Cardiac
Makes up the wall of the heart (1)

Nervous
Specialized tissue type consisting of neurons and glia that provides rapid communication and control of body function (1)
