• Anatomy: structure of body
parts; also called
morphology.
• Physiology: function of body
parts; what they do and how
they do it.

How to Study Anatomy
GROSS Anatomy:
MICROSCOPIC Anatomy:
Without a microscope;
using the naked eye to
visualize.
With a microscope; too
small to visualize with
the naked eye.

Organ Systems: A set of interrelated organs that work
together to provide a specialized function.

(anteriorly)

#8: Why is understanding the anatomical
position important to an anatomy student?
Superficial Anatomy
 Regional terms (p. 16) – names of specific body
areas
 Axial region – the main axis of the body
 Appendicular region – the limbs
 Anterior Diagram
 Posterior Diagram
 Directional terminology (Table p. 18)
 Refers to the body in anatomical position
 Standardized terms of direction are paired terms

#9: The axillary and the acromial areas are
both in the general area of the shoulder. To
what specific body area does each of these
terms apply?

Body Planes and Sections
Coronal (frontal) plane Divides body into anterior
and posterior parts.
Sagittal plane – Divides body
into unequal left and right
sides.
Median (midsagittal) plane
Specific sagittal plane that
lies vertically at the
midline; divides body into
lateral and medial parts.
Transverse plane - Divides
body into superior and
inferior parts.

through previous slide
Body Cavities:
allow for separation of organs and organ systems
Dorsal body cavity
Cranial cavity = Brain.
Vertebral cavity = encases
the spinal cord
•
•
Ventral body cavity
• Thoracic cavity = Heart
and Lungs
• Abdominopelvic cavity =
Organs of digestion and
reproduction
Other Body Cavities
Oral cavity
Nasal cavity
Orbital cavities

#11: If you wanted to separate the thoracic
cavity from the abdominal cavity of a
cadaver, which type of section would you
make?
#12: Of the spinal cord, small intestine,
uterus, and heart, which are in the dorsal
body cavity?
Organization of the Human Body
Membranes
line the internal body
cavities to reduce
friction and provide
protection.
Abdominal Regions
Divides the abdomen into nine regions to reference
abdominopelvic organs.
