The Human Body: Anatomical Regions, Directions, and Body Cavities Mrs. Rich, RN, BSN

Bell Work Define the body directions in your own words. Use phone/ipad to help you Superior inferior Anterior posterior Medial lateral Proximal Distal Caudal Cranial

At the conclusion of this lesson I CAN: Model the anatomical position Differentiate between various directional terms and model their position Identify the body cavity to which various organs are located https://www.youtube.com/watch?v=kvHWnJwBkmo

Anatomical Position Body erect Feet slightly apart Palms facing forward Thumbs point away from body Figure 1.7a

Medial Toward the midline of the body Lateral Away from the midline of the body Proximal Toward a reference point (extremity) Distal Away from a reference point (extremity) Inferior Lower or below Superior Upper or above Cephalad or Cranial Head Caudal or Caudad Tail, tail end Anterior Toward the front Posterior Toward the back Dorsal Ventral

Directional Terms Table 1.1

Directional Terms Table 1.1

Body Planes Sagittal – divides the body into right and left parts Frontal or coronal – divides the body into anterior and posterior parts Transverse or horizontal (cross section) – divides the body into superior and inferior parts

Body Planes and Sections The body may be sectioned (cut) along a flat surface called a plane. The three most common planes are: Sagittal (Median) plane (cuts body into left & right) Frontal (coronal) plane (cuts body into front & back) Transverse plane (cross section) (cuts body into superior & inferior parts) Sagittal – think twins

Body Planes and Sections Which plane could be used to separate the hemispheres of the brain? the top and bottom of the kidney? Which plane could be used to separate the anterior and posterior parts of the body? Use full sentences
