Atlas A: General Orientation to Human Anatomy Flashcards
Anatomical Position
The feet are flat on the floor and close together, the arms are held downward and supinated (palms forward), and the face is directed forward; this position is used as a reference point for directional terminology for anatomy.
Ventral Body Cavity contains:
1 thoracic cavity (includes 2 plural cavities [lungs]; 1 pericardial cavity [heart]; and 1 mediastinum [ contains the pericardial cavity])
1 abdomino-pelvic cavity, (includes abdominal and pelvic organs)
diaphragm: separates the thoracic and abdomen-pelvic cavities.
Dorsal Body Cavity contains:
1 cranial cavity (brain)
1 vertebral cavity (spinal cord)
Name the 4 body regions:
- head
- trunk- thorax; abdomen (upper – right hypochondriac region, epigastric region, and left hypochondriac region; middle – right lumbar region, umbilical region, and left lumbar region; lower – right iliac region, hypogastric region, and left iliac region)
- pelvis
- limbs
