(The muscles of the external ear are of little practical importance, and
will doubtless usually be omitted.)
(1) The External Ear. Read the description of the external ear (p. 415),
verifying it by examination and comparison of an ear still covered with
integument, in the natural condition, and of a preparation of the
isolated cartilages of the ear (Fig. 168). The latter may be obtained by
dissecting the skin and muscles from a fresh ear.
(2) The scutiform cartilage (p. 418) should be observed in the natural
position, and as isolated.
(3) The muscles of the external ear (p. 418, and Fig. 169). Those
connecting the external ear with other parts of the head have been
studied in connection with the facial muscles. The remainder will be
studied on an external ear removed according to the directions given on
page 435.
Remove the integument from the convex surface of the auricle,
sufficiently to expose the entire extent of the muscles.
