,Distal - answerssituated farthest from the midline or beginning of the body structure
Medial - answerstoward, or nearer, the midline
Lateral - answerstoward, or nearer, the side of the body, away from the midline
Major Body Cavities - answersDorsal cavity, Cranial cavity, Spinal cavity, Ventral cavity,
Thoracic Cavity, Abdominal Cavity
Dorsal Cavity - answers-located along the back of the body and head
-contains organs of nervous system
-divided into two portions
Cranial Cavity - answers-located within the skull, surrounds and protects the brain
Spinal Cavity - answers-Located within the spinal column; surrounds and protects the
spinal cord
Ventral cavity - answers-Located along the front of the body
-Contains body organs that sustain homeostasis
The Ventral Cavity is divided into - answersThoracic Cavity, Abdominal Cavity
Thoracic Cavity - answerssurrounds and protects heart/lungs
Abdominal Cavity - answersContains major organs of digestion
Quadrants of the Abdomen - answersRight upper quadrant (RUQ)
Left upper quadrant (LUQ)
Right lower quadrant (RLQ)
Left lower qudrant (LLQ)
Peritoneum - answers-Multilayered membrane
-Protects and holds the organs in place within the abdominal cavity
Parietal Peritoneum (OUTSIDE) - answers-Outer layer, lines the interior of abdominal
wall
Mesentery (MIDDLE) - answers-Double layer, attaches parts of intestine to interior
abdominal wall
Visceral Peritoneum - answersInner Layer; surround organs of abdominal cavity (on the
inside, up against in the organ)
Regions of the thorax and abdomen: - answerscomprise a descriptive system that
divides the abdomen and lower portion of the thorax into nine parts
, Right and Left Hypochondriac Regions: - answersare covered by the lower ribs
Epigastric Region: - answersis located above the stomach
Right and Left Lumbar Regions: - answersare located near the inward curve of the
spine
Umbilical Region: - answerssurrounds the umbilicus
Right and Left Iliac Regions: - answersare located near the hip bones
Hypogastric Region: - answersis located below the stomach
Pelvic Cavity: - answersthe space formed by the hip bones and contains the organs of
the reproductive and excretory systems
Abdominopelvic Cavity: - answersrefers to these two cavities as a single unit: abdominal
and pelvic
Dissection - answersDerived from the Greek word meaning 'cutting up'.
Physiology - answersThe study of the function of living organisms and their parts.
Pathology - answersThe scientific study of disease.
Cells - answersThe smallest living units of structure and function in the body.
Tissue - answersA group of cells that act together to perform a function.
Organ - answersThe heart is an example of this.
Levels of organization - answersFrom most simple to most complex: chemical, cell,
tissue, organ, system.
Anatomical position - answersThe position assumed when using directional terms to
describe the body.
Supine position - answersDescribes the body lying face up.
Prone position - answersDescribes the body lying face down.
Dorsal - answersCan be used in place of the term posterior in humans.
Anterior - answersThe opposite term for posterior in humans.
Superficial - answersThe opposite term for deep.
