cavities & planes
Question | Answer |
---|---|
Cavity | a space within the body which contains internal organs(viscera) |
Ventral Cavity | contains organs that are invloved in maintining a constant internal enviroment or homeostasis |
Thoracic Cavity | Chest Cavity |
Dorsal Cavity conatins | Cranial Cavity, Vetebral Cavity |
Cranial Cavity | Holds the brain |
Vertebral Cavity | Contains the spinal cord |
Pleural Sacs | Each contains a lung |
Mediastinum | Lies between the lungs, contains the heart, thymus gland, part of the esophagus and trachea |
Abdominal Cavity | Conatins the stoamch, small inestine, most of the large intestine,liver,spleen,kidneys, and uterus |
Pelvic Cavity | Hold the bladder,part of the large intestine,female reproductive organs, and the male scrotal sac |
Transeverse Plane | Divides the body or organ into upper and lower portions |
Parasagittal Plane | The sagittal plane does not pass through the midline but instead divides the body or organ into unequal right and left sides |
PARA | NEAR |
Midsagittal (Medain) Plane | A plane passes through the midline of the body or organ and divides it into equal right and left sides |
Sagittal Plane | Is a vertical plane that divides the body or organ into right and left sides |
Sagittal | Arrow |
Planes | Sagittal, Midsagaittal, Transverse, Parasagittal, Frontal, Oblique |
Oblique Plane | Passes through the body or organ at an angle between a transverse plane and a sagittal plane or between a transverse plane and a frontal plane |
Frontal Plane | Divides the body or organ into front and back portions |
Longitudinal Sections | Sections that are produced by a plane running along the long axis of a long narrow structure |
Cross-Sections | Sections that are produced by a plane running perpendicular to the long axis |
Diaphragm | Separtes the thoracic cavity from the abdominopelvic cavity |
Abdominopelvic Cavity | Consits of two continunous cavities: abdominal cavity and the pelvic cavity |
Pericardial Cavity | Surrounds the heart and each pleural cavity contains a lung |
