3 sectional planes
Frontal, Sagittal, transverse
Serial reconstruction
Important for studying histological structure and analyzing images produced by radiological procedures
Body Cavities
Protect delicate organs and permit changes in size of organs
Diaphragm
Separates the superior thoracic cavity from the inferior abdominopelvic cavity
The abdominopelvic cavity contains the
peritoneal cavity which is lined by the peritoneal. Many digestive organs are supported and stabilized by mesenteries.
The abdominal cavity extends from
the inferior surface of the diaphragm to an imaginary line drawn from the inferior surface of the most inferior spinal vertebra to the anterior and superior margin of pelvic girdle. Inferior to this is the pelvic cavity
The thoracic and abdominopelvic cavities contain
Narrow fluid filled spaces lined by serous membrane. The thoracic cavity contains 2 pleural cavities separated by the mediastinum
The mediastinum contains the
Thymus, trachea, esophagus, blood vessels, and pericardial cavity.
Pleura
The membrane lining the plural cavities
Serous pericardium
The membrane lining the pericardial cavity
Epithelium
Is an avascular sheet of cells that forms a surface, lining, or covering
Tissues
Collections specialized cells that are organized to preform a number of functions
Exocrine secretions
Are discharged through ducts to the exterior
Endocrine secretions
Aka hormone, are released by gland cells into the interstitial fluid
