Mitosis |
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. |
|
Cytokinesis |
the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. |
|
Centromeres |
the region of a chromosome to which the microtubules of the spindle attach. |
|
Tissues |
any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
|
Epithelial Tissue |
line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. |
|
Simple epithelial tissue |
One layer |
|
Statiphied epithelial |
Found as a protective covering where friction is common. |
|
Stratified cuboidal |
2 layers of cuboidal cells |
|
Stratified columnar |
Surface cells are columnar, cells underneath vary in size and shape |
|
Transitional Epithelia |
Shape of cells depends upon the amount stretching. |
|
Glandular Epithelial |
One or more cells responsible for secreting a particular product. |
|
Endocrine gland |
Ductless since secretions diffuse into blood vessels. |
|
Endocrine gland |
Ductless since secretions diffuse into blood vessels. |
|
