Planes, sections, etc. Flashcards
Imaginary lines drawn through the body at various parts to separate the body into sections
Planes
Cut made through the body in the direction of a certain plane
Section
Divides the body into right and left parts
Median or Midsagittal plane
Vertical cut at right angles to sagittal plane, divided the body into anterior & posterior portions
Frontal (Coronal) Plane
cross-section, a horizontal cut that divided the body into upper & lower parts
Transverse Plane
Openings within the torso which contain organs, protect delicate organs from accidental shocks&bumps, & permit the expansion& contraction of organs without disrupting the activities of other organs
Body cavities
Located on the posterior/dorsal surface of the body & surrounds the brain & the spinal cord
Dorsal cavity
The bones of the skull create the cranial cavity to protect the brain
Cranial Cavity
Formed by the vertebrae of the spine & surrounds the spinal cord
Spinal(Vertebral) Cavity
Located on the anterior/ventral surface of the body, which contains the chest & abdomen. The walls are composed of skin, muscle, connective tissue, bone(for 2 cavities), & the serous membrane
Ventral Cavity
The portion of ventral cavity superior to the diaphragm
Thoracic Cavity
The spaces surrounding each lung
Pleural Cavities
A broad middle tissue mass of the thoracic cavity dividing the lungs into two cavities. It includes the aorta, other great blood vessels, esophagus, trachea, thymus, pericardial cavity and the heart
Mediastinum
Space in which the heart is located
Pericardial Cavity
The portion of the ventral cavity inferior to the diaphragm
Abdominopelvic Cavity
