Directional Terms Lecture 02
Anatomical Directions Body Location Meaning Ventral or Anterior At or near the front surface of the body or its parts Dorsal or posterior At or near the back surface of the body or its parts Lateral At or near the side surface of the body or its parts
Body Location Medial Central Peripheral Proximal Meaning At or toward the midline of the body Toward the center of the body Away from the center of the body Nearest to the point of attachment Distal Furthest from the point of attachment Cavity A hollow part or space in a structure
Body Location External Internal Palmar Inferior Superior Caudal Cranial Meaning The outside or outer part of a structure The inside or inner part of a structure Concerning the palm of the hand Beneath Over or above Away from the head, toward the tail, inferior portion of the body Pertaining to the skull
Body Planes • Midsagittal – Divides body into equal right and left portions • Midline of the body – Medial – Lateral
Body Planes…
Body Planes… • Frontal or Coronal – Divides body into front and back portions
Body Planes…
Body Planes… • Transverse – Cuts across body – Superior (Cranial, Cephalic) – Inferior (Caudal)
Body Planes…
Body Regions • Nine abdominal regions – Identified from left to right – Move from top to bottom – One row at a time
Body Regions…
Abdominal Quadrants • Landmark = umbilicus (navel) • Quadrants – RUQ, – LUQ, – RLQ, – LLQ
Abdominal Quadrants…
Body Cavities • Dorsal Cavity – Cranial – Spinal • Ventral Cavity – Thoracic – Abdominal – Pelvic
Body Cavities…
Divisions of the Back • Cervical Vertebrae (C 1 – C 7) • Thoracic Vertebrae (T 1 – T 12) • Lumbar Vertebrae (L 1 – L 5) • Sacrum • Coccyx
Divisions of the Back…
