Anatomical Terminology Anatomical Position

 Relative positions of body parts can change when we move our body  Anatomical terminology assumes a standard position  Right vs Left Body Regions

 Head  The vocabulary of  Neck anatomy and physiology roots in  Trunk Latin, and was  Upper limbs developed so that  Lower limbs there would be a common, international language Directional Terms

 Anterior ------towards the front of body  Posterior------towards the back of body  Ventral------”belly”  Dorsal------” back”  Superior/Cranial/Cephalic-----Towards head  Inferior/Caudal------Towards feet (tail)  Medial------Towards midline  Lateral------Away from midline

Directional Terms, con’t…

 Proximal------Near the point of attachment/origin  Distal------Far from the point of origin  Superficial------Towards the surface of body  Deep------Away from the surface Planes and Sections

 Sagittal----divides body or organ into right and left parts  Mid-sagittal—equal halves  Parasagittal---unequal halves

 Frontal (coronal)—divides body or organ into anterior and posterior parts  Transverse---divides body or organ into superior and inferior parts

 Oblique---passes through organ or body at an angle between transverse and sagittal

Body Cavities

 Large spaces within the body that contain, protect, separate and support internal organs  Cranial cavity—contains brain

 Vertebral cavity—Contains spinal cord and the beginning of spinal nerves  Thoracic cavity—chest cavity, contains pleural and pericardial cavities and mediastinum  Pleural—each surrounds lung, the serous membrane is the pleura  Pericardial—surrounds the heart, the serous membrane is the pericardium  Mediastinum—central portion of thoracic cavity between the lungs  Abdominopelvic cavity  Abdominal cavity—contains stomach, spleen, liver, gall bladder, small intestine and most of the large intestine; serous membrane is the peritoneum

 Pelvic cavity—contains lower part of large intestine and reproductive organs

 Viscera—organs inside the thoracic and abdominopelvic cavities

 Serous membrane—thin, slippery, double layered membrane  Parietal layer—lines the walls of cavities (outer layer)  Visceral layer—covers and adheres to viscera (inner layer) Abdominopelvic Regions

 Right hypochondriac  Epigastric  Left hypochondriac  Right lumbar  Umbilical  Left lumber  Right inguinal (iliac)  Hypogastric  Left inguinal (iliac) Assignment

 Using notes and Chapter 1, review the vocabulary pertaining to anatomical position
