A&P 1 Unit 1 (Lab) [Intro to Anatomical Terms] Flashcards
Anatomical Position
The specimen is presented facing forward, with the toes pointing forward, the feet shoulder width apart, and the palms facing forward. (This presentation of anatomical specimens creates a standard point of reference that facilitates communication among scientists and healthcare professionals.)
Supine
Facing up.
Prone
Facing down.
Anterior (ventral)
Front.
Posterior (dorsal)
Back.
Proximal
Toward an attached base.
Distal
Away from an attached base.
Superior (cranial)
Above; at a higher level (in the human body, toward the head).
Inferior (caudal)
Below; at a lower level.
Superficial
At, near, or relatively close to the body surface.
Deep
Farther from the body surface.
Medial
Toward the body’s longitudinal axis; toward the midsagittal plane.
Lateral
Away from the body’s longitudinal axis; away from the midsagittal plane.

Planta (sole)
Posterior (dorsal) Cavity
Cranial Cavity (contains the brain) & Vertebral Cavity (contains the spinal cord)
Anterior (ventral) Cavity
Thoracic Cavity (Pericadial Cavity & Pleural Cavities) & Abdominopelvic Cavity (Abdominal Cavity & Pelvic Cavity)
Serous Membrane
Living sheets of cells associated with the thoracic and abdominopelvic cavities. Secretes Cavity specific fluid to lubricate and cushion the organs in the cavity.
Visceral Pericardium (serous membrane)
Clings to the heart.
Parietal Pericardium (serous membrane)
Lines the pericardial cavity.
Visceral Pleura (serous membrane)
Clings to the lungs surface.
Parietal Pleura (serous membrane)
Lines the pleural cavity.
Visceral Peritoneum (serous membrane)
Covers many organs in the abdominopelvic cavity.
Parietal Peritoneum (serous membrane)
Lines the body cavity wall.
Transverse or Horizontal (plane)
Separates superior and inferior portions of the body. A cut in this plane is called a CROSS SECTION.
Sagittal (plane)
Separates right and left portions.
Midsagittal (plane)
Or MEDIAN SECTION, the plane passes through the midline, dividing the body into right and left halves.
Parasagittal (plane)
Cut parallel to the midsagittal plane, separates the body into right and left portions of unequal size.
