GENERAL ANATOMY OF THE MAMMALIAN BODY 
3 
Ribs. —True, false, floating—note number of each and 
possibilities of variation. 
Sternum. —Note relation to the ribs. 
( b ) Appendicular Skeleton. 
Girdles. 
Pectoral.—Clavicles, scapulae. 
Pelvic.—Ossa coxae, each consisting of iliac region, ischial 
region, and pubic region. 
Appendages. 
Anterior (Arm).—Humerus, radius and ulna, carpus, 
metacarpus, phalanges. 
Posterior (Leg).—Femur, patella, tibia and fibula, tarsus, 
metatarsus, phalanges. 
2. Cavities Outlined by the Skeleton. 
In Head. —Cranial region of the neural cavity, auditory 
cavities, orbital cavities, nasal cavities, mouth cavity. 
In Trunk. —Spinal region of neural cavity, or spinal canal 
(continuation posteriorly of the cranial cavity); body cavity (or 
coelom), divisible into thoracic, abdominal, and pelvic regions.

3. Identification of Superficial Bony Parts upon the Living Body. 
Method.— By palpation locate upon your own body, or that of a 
fellow-student or a laboratory subject, those bony surfaces, ridges, 
and other protuberances which are superficial and thus readily felt 
through the skin. By comparison with an articulated human 
skeleton, and with anatomical manikins, discover the identity of 
each superficial region thus located, and from the following list, 
with the aid of anatomical atlases and reference books, learn the 
names of these superficial bony parts. Record the location of the 
superficial bony parts thus identified, upon outline drawings 1 of 
the human body, ventral, lateral and dorsal views, supplied by the 
laboratory . 
In Head.— Dome of cranium, from the occipital protuberance 
to the superciliary arches; mastoid processes, zygomatic arches, 
1 Outline drawings of the human body in ventral, lateral, and dorsal aspects may 
be readily traced from various art atlases by the individual students, or such a 
tracing may be manifolded by means of a mimeograph, hectograph, or other mani¬ 
folding apparatus.
