  16. The Body as a Whole Level of Organization Cell: It carries all functions of life. Tissue: group of cells with the same activities: epithelial, connective, muscular and nervous tissues. Organ: group of tissues perform special function System: group of organs with common function

  17. Planes of the Body Midsagittal (Median) plane: It divides the body into a right and left half. Sagittal plane: It divides the body into unequal right and left side. Coronal (Frontal) plane: It divides the body into anterior (ventral) and posterior (dorsal) portion. Transverse (Horizontal) plane: It divides the body into superior (upper) and inferior (lower) portions.

  18. Body Cavities Coronal plane divides the body into 2 dorsal and 2 ventral cavities: Dorsal cavities: -Cranial cavity contains the brain. -Spinal cavity contains the spinal cord. Ventral cavities: -Thoracic cavity contains heart and lungs. -Abdominopelvic cavity contains digestive, excretory and reproductive organs. Ventral cavities are separated by the diaphragm.

  19. The Abdominopelvic Region 9 regions 4 quadrants 1- Right hypochondriac 1-Right upper quadrant 2-Epigastric 2-Left upper quadrant 3-Left hypochondriac 3-Right lower quadrant 4-Right lumbar 4-Left lower quadrant 5-Umbilical 6-Left lumber 7-Right inguinal 8-Hypogastric 9-Left inguinal

  20. Directional Terms Superficial:toward the surface of the body. Deep (internal): away from surface of body. Medial: toward midline of the body or structure. Lateral: away from midline of body or structure. Superior (cranial): toward the head or upper part Inferior (caudal): away from head, to lower part. Proximal: nearer to the trunk or a structure. Distal: away from the trunk or a structure. Anterior (ventral): near the front of the body. Posterior (dorsal): near the back of the body. Parietal: pertaining to the outer wall of body cavity. Visceral: pertaining to the covering of an organ.
