Term | Definition |
Tissues | Are a group of cells with a common embryonic origin that function together to carry out specialized activities |
4 Types of Tissues | Epithelial, Connective, Muscular, and Nervous |
Epithelial Tissues | Cover body surfaces and form protective barriers. Also form glands and line hollow organs, body cavities, and ducts. Secretes mucous, hormones, and other substances. |
Connective Tissues | Protect, supports, and bind organs. Ex: Fat, RBC, WBC, and Platelets |
Muscular Tissues | Generates heat used by the body and the physical force needed to make body structures move. |
Nervous Tissues | Detects changes in the body and respond by generating nerve impulses |
Tissues develop from 3 primary germ layers known as... | Endoderm, Mesoderm, and Ectoderm |
Epithelial tissues develop from... | all three germ layers |
Connective and Muscle tissues develop from... | mesoder |
Nervous tissue develops from... | ectoderm |
Simple Squamous Epithelium | Composed of a single layer of flat cells found in air sacs of lungs, capillaries, lining of blood vessels, heart, and lymphatic vessels. |
Simple Cuboidal Epithelium | Composed of a single layer of cubed shaped cells often found lining the tubules of the kidneys and many other glands. |
Simple Columnar Epithelium | Forms a single layer of column-like cells common in the digestive tract |
Goblet cells | Simple columnar cells that have differentiated |
Pseudostratified Columnar Epithelium | Appears to have layers due to having nuclei at various depths, but is a single layer of cells attached to the basement membrane. Characteristic of the upper respiratory tract |
Stratified Squamous Epithelium | Has an apical surface that is made up of squamous (flat) cells, with other layers that have different shapes--ideal for protection against strong friction forces. Featured in outer layers of skin |
Stratified Cuboidal Epithelium | Has an apical surface made up of two or more layers of cube-shaped cells located in sweat glads and part of urethra |
Transitional Epithelium | Cells change shape depending on the state of stretch in the tissue. Ex: Bladder domes cells when empty or flattened cells when full |
