Organization of the Body Flashcards
Imaginary lines drawn through the body that separates the body.
Body Planes
a two-dimensional surface of a three-dimensional structure that has been cut.
section
an imaginary two-dimensional surface that passes through the body.
plane
the plane divides the body or organ vertically into right and left sides.
Sagittal Plane
it runs down directly to the middle of the body
Midsagittal Plane
another term for “midsagittal”
Median Plane
it divides the body into unequal right ad left side
Parasagittal Plane
another term for “Parasagittal Plane”
Longitudinal Section
the plane that divide the body or organ into anterior (front) portion or posterior (rear) portion. it is referred to as coronal plane.
Frontal Plane
the plane that divides the body or organ horizontally into upper and lower portions.
Transverse Plane
Essential for describing the relative locations of different body structure
Anatomical Direction
Describes the front or direction toward the front (or the belly) of the body. The toes are anterior to the foot
Anterior (Vental)
Describes the back or direction toward the back of the body. The popliteus is posterior to the patella. (Toward the rear or back)
Posterior (Dorsal)
describes a position above or higher than another part of the body proper. The orbits are superior to the oris.
Superior (Cranial)
describes a position below (or toward the feet) or lower than another part of the body proper; near or toward the tail (in humans, the coccyx, or lowest part of the spinal column). The pelvis is inferior to the abdomen.
Inferior (Caudal)
describes toward the side or direction toward the side of the body. The thumb (pollex) is lateral to the digits.
Lateral
describes toward the middle or direction toward the middle of the body. The hallux is the medial toe.
Medial
describes a position in a limb that is nearer to the point of attachment or closer form the trunk or origin of the body. The brachium is proximal to the antebrachium.
Proximal
describes a position in a limb that is farther from the point of attachment or the trunk or origin of the body. The crus is distal to the femur.
Distal
describes a position towards or on the surface closer to the surface of the body. The skin is superficial to the bones
Superfical
describes a position farther from the surface of the body. The brain is deep into the skull.
Deep (internal)
the largest body compartments.
Dorsal cavity and Ventral cavity
Contains the brain
Cranial Cavity
contains the spinal cord
Spinal Cavity
contains the lungs
Pleural Cavity
contains the heart
Pericardial Cavity
central region that separates the lungs sits between the sternum and the vertebral column
Mediastinum
upper part; contains the stomach, small intestines, most of the large intestines (except colon and rectum), liver, gallbladder, pancreas, and spleen
Abdominal Cavity
lower part; contains the reproductive organs, urinary bladder, and the last part of the large intestines (colon and rectum)
Pelvic Cavity
