Study Notes

Anatomical Planes

  • The horizontal (transverse) plane divides the body into upper and lower parts.

Anatomical Terms in Movement

  • Adduction of the hip squeezes the legs together, moving towards the midline.
  • Medial rotation is a rotational movement towards the midline.
  • Lateral rotation is a rotating movement away from the midline.
  • Circumduction is the combination of flexion, extension, abduction, adduction, and medial and lateral rotation movements (e.g., in the shoulder joint).

Membranes of the Anterior (Ventral) Body Cavity

  • There are three serous cavities and their associated membranes:
    • Pleura: a serous membrane surrounding the lungs in the pleural cavity.
    • Pericardium: a serous membrane surrounding the heart in the pericardial cavity.
    • Peritoneum: a serous membrane surrounding several organs in the abdominopelvic cavity.
