  1. The Human Body: An Orientation Anatomical Terms

  2. Anatomical Position Body erect, feet slightly apart, palms facing forward, thumbs point away from the body Figure 1.7a

  3. Directional Terms Superior –closer to the head inferior –away from the head Anterior- front of body posterior –back of the body Medial-towards midline lateral- away from midline (side) intermediate between a more medial and lateral structure

  4. Directional Terms Proximal – closer to origin or attachment distal –farther from the origin of the body Superficial- closer to body surface (skin) deep –away from the body surface (bone)

  5. Directional Terms Table 1.1

  6. Directional Terms Table 1.1 (continued)

  7. Directional Terms Table 1.1 (continued)

  8. Regional Terms Axial – head, neck, and trunk Appendicular – appendages or limbs Figure 1.7a

  9. Figure 1.7b

  10. Body Planes Sagittal and medial – divides the body into right and left parts Midsagittal – sagittal plane that lies on the midline Frontal or coronal – divides the body into anterior and posterior parts Transverse or horizontal (cross section) – divides the body into superior and inferior parts Oblique section – cuts made diagonally

  11. Body Planes Figure 1.8

  12. Body Cavities • Dorsal cavity protects the nervous system, and is divided into two subdivisions • Cranial cavity is within the skull and encases the brain • Vertebral cavity runs within the vertebral column and encases the spinal cord • Ventral cavity houses the internal organs (viscera), and is divided into two subdivisions: thoracic and abdominopelvic

  13. Body Cavities Figure 1.9

  14. Body Cavities • Thoracic cavity –divided into pleural cavities, the mediastinum, and the pericardial cavity • Pleural cavities – each houses a lung • Mediastinum – contains the pericardial cavity, and surrounds the remaining thoracic organs • Pericardial – encloses the heart

  15. Body Cavities • The abdominopelvic cavity is separated from the superior thoracic cavity by the dome-shaped diaphragm • It is composed of two subdivisions • Abdominal cavity – contains the stomach, intestines, spleen, liver, and other organs • Pelvic cavity – lies within the pelvis and contains the bladder, reproductive organs, and rectum

  16. Ventral Body Cavity Membranes Parietal serosa covering the body walls Visceral serosa covering the internal organs Serous fluid separates the serosae Figure 1.10

  17. Other Body Cavities Oral and digestive – mouth and cavities of the digestive organs Nasal –located within and posterior to the nose Orbital – house the eyes Middle ear – contain bones (ossicles) that transmit sound vibrations Synovial – joint cavities
