When navigating the body,
directional terms help determine
the exact location of a structure
 All
directional terms
are based on the
body being in the
“anatomical position”
• Facing forward
• Palms outward
 Superior/inferior
(cranial/caudal)
 Anterior/posterior (ventral/dorsal)
 Medial/lateral
 Proximal/distal (usually used with
reference to the limbs)
 Superficial/deep

and its organs
 These lines run longitudinally,

 Spaces
within the body that contain the
internal organs
 There are 7 cavities – two are closed
and 5 are open
1.


The dorsal cavity
Located in the posterior region of the
body
Contains two smaller cavities
Cranial cavity – contains the brain
Vertebral cavity – contains the spinal
cord
2. The ventral cavity
- Located in the anterior region of the trunk
- Contains two smaller cavities separated by the
diaphragm

Thoracic cavity – separated into two compartments by
the medisternum which contains the aorta, esophagus,
trachea, thymus
 Pleural cavities – the spaces surrounding each lung
 Pericardial cavity – the space in which the heart is located

Abdominopelvic cavity
- Large abdominal cavity – the space that contains the stomach, liver,
spleen, gall bladder, kidney, and most of the large and small intestine
- The pelvic cavity – the space that contains the terminal part of the
large intestine, urinary bladder, internal reproductive organs
 In
what cavity would you find the spinal
cord?
 What separates the thoracic and
abdominal cavities?

for specific body areas that
have a special nerve or vascular supply
or those that perform a special function
