Lecture 2
Terminology and Body Plan for
the Human Body
1-1
Anatomical Position:
The Standard for Reference
• Anatomical Position
– Body erect, face forward,
feet together, palms face
forward
• Other Body Positions
– Supine: lying face upward
– Prone: lying face downward
1-2
Body Planes
• Sagittal / Midsagittal
(Median)/ Parasagittal
• Frontal (Coronal)
• Transverse (Horizontal) /
Cross
• Oblique: Other than at a
right angle

Terminology and Body Plan
• Directional Terms
– Superior versus
Inferior
– Anterior/Ventral
versus
Posterior/Dorsal
– Medial versus
Lateral
– Proximal versus
Distal
– Superficial versus
Deep

directional terms is mismatched?
(a) Popliteal/femoral; distal
(b) Patellar/crural; proximal
(c) Antebrachial/abdomen; lateral
(d) Brachial/carpal; superior
(e) Abdominal/vertebral; anterior

Body Cavities
Fig. 1.9
1-8
Serous Membranes
• Cover the organs of trunk cavities & line them
– Parietal lines cavity walls
– Visceral covers organs
– Serous fluid secreted for lubrication by membranes
Fig. 1.10
1-9
Serous Membranes
• Named for their
specific cavity & organs
–Pericardium refers to
heart
–Pleura refers to lungs
and thoracic cavity
–Peritoneum refers to
abdominopelvic cavity

Points to Remember
• Anatomical terms are very precise in anatomy so
that one can accurately describe the body and its
many parts.
• The anatomical position is our universal reference
for directional terms and body planes.
• Body cavities contain and often separate organs.
• Serous membranes cover the surfaces of organs
and the wall of the trunk cavity.
