Definition
| densely packed with cells. |
|
|
Term
| Connective and supporting tissues |
|
Definition
| not densely packed w/cells, fibers dominate the area. |
|
|
Term
|
Definition
| the tissues that form blood cells. |
|
|
Term
|
Definition
| muscle tissue generates tension. |
|
|
Term
|
Definition
| associated with the nervous system; relays information. |
|
|
Term
| How to you differentiate a microspcopic view of an epithelial tissue from a connective or supporting tissue? |
|
Definition
| An epithileal tissue has many densely packed cells and connective tissues are loose there are fewer cells. |
|
|
Term
| Define Enodothelium and Mesothelium. How are the tissues the same and how are they different? |
|
Definition
| They are both simple and squamos epithilium. Endothelium is the tissue that forms a single layer of cells lining various organs and the mesothelium is the epithelium that lines the pleurae, peritoneum, and pericardium. |

Term
| Connective tissue categories |
|
Definition
Connective tissue proper
Recticular tissue
Adipose tissue |
|
|
Term
| Supporting tissue categories |
|
Definition
|
|
Term
| What cells are fixed cells in connective tissue? |
|
Definition
Mesenchymal- along the capllaries of loose connective tissue.
Fibroblast/Fibrocyte-they adhere to collagen adnn elastin fibers. They are active in wound repair.
Adipocyte- have one large lipid cell. |
|
|
Term
| What cells in connective tissue are considered wandering cells? |
|
Definition
Immune response white blood cells- short term events associated w/tissue reactions to injury and disease.
Macrophage: resting and wandering, migrate to sites of tissue injury.
Mast cell/Mastocyte-detects foreign substances and innitiate an inflammatory response.
Lymphocyte-abundant in the submoscal connective tissues of the repiratory and digestive tracts.
Plasma cell/plasmocyte- common in the connective tissue of the intestinal passageways. |
|
|
Term
| What are the principal fibers of connective tissue and clearly describe the functional role of each of the fibers. |
|
Definition
Collagen fibers-they do not stretch. They are major components in cartilage and bone tissue. It is characterized by its great tensile strength.
Elastic fibers- They can be stretched very easiley and can reach 150% of their original length before breaking. They maintain and almost perfect recoil. |
|
|
Term
| How do anatomists classify connective tissues. |
|
Definition
| Connective tissue is named for the most prominent feature of the tissue and the arrangement of that feature in the tissue. |
|
|
Term
| Epidermis is made of what tissue? |
|
Definition
| Stratified squamos epithelial. |
|
|
Term
| Dermis is made of what tissue? |
|
Definition
| Dense irregular connective tissue. |
|
|
Term
| What is the hypodermis made of? |
|
Definition
|
|
Term
| List five functions of the integumentary system. |
|
Definition
| Protection, Sensory perception, excretion, sociosexual communication and identification, an dthermoregulations and water balance. |
|
|
Term
| Name each stratum of the epidermis and its functional significance. |
|
Definition
| Basale or germinativum- growth layer and protection from radiation. Spinosum- strong binding. Granulosum- formation of lipidic extracellular substance. Corneum-dead cells filled with polymerized keratin. |
|
|
Term
| What cells are responsible for the different colors observed in the skin of humans? Describe the relationship these cells have with the major category of epidermal cells and describe how they distribute their pigment. |
|
Definition
| Stratum basale of germinativum. It produces melatonin that moves toward the surface as new cells are produced. |
