Directional Terms Superior (sup) Pertaining to above Inferior (inf) Pertaining to below Cranial Pertaining to the head Cephalic Pertaining to the head Caudad Toward the tail (downward) Caudal Pertaining to the tail (downward)
Directional Terms Medial (med) Pertaining to the middle Lateral (lat) Pertaining to the side Unilateral Pertaining to one side Bilateral Pertaining to two sides Contralateral Pertaining to the opposite side Ipsilateral Pertaining to the same side
Directional Terms Superficial At, near, or relatively close to thebody surface Deep Farther from the body surface
Directional Terms Some directional terms arebased on the relationship to theaxial and appendicular skeleton Axial and Appendicular Skeleton Axial Skeleton includes The skull (cranial and facial bones)Bones associated with the craniumThe vertebral columnThe thoracic cage Appendicular Skeleton includes Girdles (pectoral and pelvic) Extremities (upper and lower)
Directional Terms Proximal Pertaining to near (to the point ofattachment of a body part Distal Pertaining to away (from the pointof attachment of a body part)
Anatomic Planes Frontal or Coronal A plane that separates the body orstructure into anterior and posteriorsections Sagittal A plane separating the body or a structureinto left and right sections A midsagittal plane seperates into equal leftand right halves Transverse or Horizontal A plane that separates the body orstructure into superior and inferior sections Oblique A plane that separates the body orstructure and is not one of those listedabove
Abdominopelvic RegionsDivisions of the abdominopelvic cavity into 9 artificial divisionfor note taking and communication Umbilical region Around the navel (umbilicus) Epigastric region Directly above the umbilical region Hypogastric region Directly below the umbilical region Hypochondriac region To the right and left of the epigastric region Lumbar region To the right and left of the umbilical region Iliac region To the right and left of the hypogastricregion
Abdominopelvic QuadrantsDivisions of the abdominopelvic cavity into 4 artificial divisionfor note taking and communication Right upper quadrant (RUQ) Refers to the area encompassingthe right lobe of the liver*, thegallbladder*, part of the pancreas,portions of the small and largeintestines, the right kidney Left upper quadrant (LUQ) Refers to the area encompassingthe left lobe of the liver, thestomach, the spleen, part of thepancreas, portions of the smalland large intestines, the leftkidney
Abdominopelvic QuadrantsDivisions of the abdominopelvic cavity into 4 artificial divisionfor note taking and communication Right lower quadrant (RLQ) Refers to the area encompassingportions of the small and largeintestines, the appendix*, the rightureter, and the right ovary anduterine tube in women and rightspermatic duct in men Left lower quadrant (LLQ) Refers to the area encompassingportions of the small and largeintestines*, the left ureter, and theleft ovary and uterine tube in womenand the left spermatic duct in men
Visceral Pain Patterns * On the previous slides, these arekey structures that may indicatepathology with pain in a particularquadrant. While pain in a particular quadrantis should be considered, it isimportant to know that visceralpathology can refer pain to areasaway from their location. Note: These referral zones are notpart of this class.

Directional derivatives and gradient vectors (Sect. 14.5). I Directional derivative of functions of two variables. I Partial derivatives and directional derivatives. I Directional derivative of functions of three variables. I The gradient vector and directional derivatives. I Properties of the the gradient vector.
Three-phase Directional Overcurrent (67) Each one of the three-phase overcurrent stages of the P127 can be independently configured as directional protection with specific relay characteristic angle (RCA) settings and boundaries. Each directional stage has instantaneous (start) forward/reverse outputs available. Directional Overcurrent Tripping .
Here is a quick review of Basic Anatomical Review of Planes, Directions, Regions and Cavities. This is meant as a review and guide to help. It is only the beginning of a fun and fulfilling exploration into the body. Anatomical Position In order to avoid confusion when describing the body, it is always described in the anatomical position.

Figure 5 Default datum planes Figure 6 Datum planes as solid plates Select the Datum Plane button now. Since we currently have no features in the model, Wildfire rightly assumes that we want to create the three standard datum planes. The datum planes represent three orthogonal planes to be used as references for features that will be created later.
