Terminology and the Body Planes Flashcards
These are the words used to describe the location of an anatomical structure by comparing its position to other structures within the body or within the orientation of the body itself
Directional Terms
What directional terms that describes the front or direction toward the front of the body. Front.
(Eg. The toes are anterior to the foot)
Anterior or Vertral
What directional terms where it describes the back or direction toward the back of the body. Back.
(Eg. The popliteus is posterior to the patella)
Posterior or Dorsal
What directional terms where it describes a position above or higher than another part of the body proper. Higher.
(Eg. The orbits are superior to the Oris)
Superior or Cranial
What directional terms where it describes a position below 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). Ex: The pelvis is inferior to the abdomen
Inferior or Caudal
What directional terms where it describes the side of direction toward the side of the body.
Ex: The thumb (pollex) is lateral to the digits.
Lateral
What directional terms where it describes the middle or direction toward the middle of the body.
Ex: The hallux is the medial toe
Medial
What directional terms where it describes a position in a limb that is bearer to the point of attachment or the trunk of the body.
Ex: The brachium is proximal to the antebrachium
Proximal
What directional terms where it describes a position in a limb that is farther from the point of attachment or the trunk of the body.
Ex: The crus is distal to the femur
Distal
What directional terms where it describes a position closer to the surface of the body
Ex: The skin is superficial to the bones
Superficial
What directional terms where it describes a position farther from the surface of the body
Ex: The brain is deep to the skull
Deep
It is an imaginary two-dimensional surface that passes through the body.
Body Plane
There are three planes commonly referred to anatomy and medicine. What are these planes?
(Sag,Front,Trans Plane)
Sagittal Plane
Frontal Plane
Transversal Plane
It is the plane that divides the body or an organ vertically into right and left sides
Sagittal Plane
What are the two sagittal planes
Midsagittal or Median Plane
Parasagittal or Longitudinal Section
A sagittal plane where this vertical plane runs directly down the middle of the body
Midsagittal or Medial Plane
A sagittal plane where it divides the body into unequal right and left sides
Parasagittal or Longitudinal Section
It is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. It is often referred to as Coronal Plane (“Corona” is Latin for “Crown”)
Frontal Plane
It is the plane that divides the body or organ horizontally into upper and lower portions. It also produce images referred to as cross sections.
Transverse Plane
These cavities contain and protect delicate internal organs, and the ventral cavity allows for significant changes in the size and shape of the organs as they perform their functions. The Lungs, heart, stomach and intestines, for example, can expand and contract without distorting other tissues or disrupting the activity of nearby organs.
It maintains it’s internal organization by means of membranes, sheaths, and other structures that separate compartments
Body Cavities
What are the 2 largest body compartments
Dorsal Cavity Ventral Cavity (more larger)
How many quadrants are there in abdomen and What are those?
4 Quadrants: Right Upper Quadrant Left Upper Quadrant Right Lower Quadrant Left Lower Quadrant
How many Divisions does our Abdomen have?
And what are those
9 Divisions: Right Hypochondriac Region Epigastric Region Left Hypochondriac Region Right Lumbar Region Umbilical Region Left Lumbar Region Right Iliac Region Hypogastric Region Left Hypochondriac Region
It is the area beneath the hypogastric region at the bottom of the pelvic cavity and is sometimes considered to be a tenth division in this system
Perineum
