|
Explain the hierarchy of structural organization:
|
1. Chemical Level: atoms form molecules
2. Cellular Level: cells and organelles. 3. Tissue Level: a group of cells performing a common function. 4. Organ Level: a discrete structure made up of more than one tissue. 5. Organ System: organs working together for a common purpose. 6. Organismal level: the result of all simpler levels working in unison. |
|
Describe 4 types of tissue:
|
1. epithelial: covers the surface and line cavities. (Ex: skin and GI tract)
2. connective: body support and protects organs. (Ex: fat, ligaments, bone, cartilage & blood) 3. muscle: movement. 4. nervous: transmits electrical pulses. |
|

|
What are the 3 body planes and sections?
|
1. Coronal (frontal) plane: lies vertically and divides body ito anterior and posterior parts.
2. Median (midsagittal) plane: specific saittal plane that lies vertically in the midline. 3. Transverse plane: Runs horizontally and divides body into superior and inferior parts. |
|
