|
Resolution |
Function in microscope that enables the observer to distinguish structures and points that are separated by short distances; gives sharp detail. |
|
|
Histology |
Study of tissues and their microscopic structure. |
|
|
Basic tissue types |
Epithelial, connective, muscle, and nervous |
|
|
Basement Membrane |
Underlying tissue that is attached to epithelium. Thin extracellular layer composed of the basal lamina and the reticular lamina. |
|
|
Basal Surface |
Side of epithelium that faces the basement membrane. |
|
|
Apical Surface |
The side of the epithelium that faces the body cavity, lumen, or environment |
|
|
Squamous Cells |
Thin and flat cells, much broader than they are thick |
|
|
Cuboidal Cells |
Shaped like a cube |
|
|
Columnar Cells |
Taller than they are wide. |
|
|
Simple Epithelium |
Comprised of a single layer of cells in which every cell touches the basement membrane |
|
|
Stratified epithelium |
Consists of multiple layers of cells. Classified by the shape of cell at the apical surface. |
|
|
Mesothelium |
The simple squamous Epithelium that lines body cavities. |
|
|
Endothelium |
Layer that lines the heart and blood vessels. |
|
|
Microvilli |
Utilized by Simple columnar epithelium cells to increase surface area for transport |
|
|
Cilia |
Utilized by Simple columnar Epithelium to allow substances to be moved across the apical surface. |
|
|
Skeletal muscle |
Found in skeletal muscles that are attached to the skeleton and can be controlled voluntarily to produce body movement. Is multinucleate, each cell will have several nuclei |
|
|
Smooth Muscle |
Found in the wall of hollow organs and is involuntarily controlled. |
|
|
Cardiac Muscle |
Comprises the majority of the wall of the heart and is involuntarily controlled. Cells are connected by special intercellular connections known as intercalated disks |
