auricularis anterior of man.)—A very thin band of fibres eigh 
to ten millimeters broad. 
Origin on the middle two-thirds of the caudoventral edg: 
of the scutiform cartilage. The fibres pass nearly ventra 
and are zzserted along the medial or caudal surface of thi 
tragus. 
Relations. — Outer surface with the auricular cartilage 
Inner surface with the temporal muscle or with the pad of fa 
separating this from the auricle. 
Action.—Pulls the concha dorsocraniad. 
(c) The remainder of the muscles of the ear interconnec 
parts of the auricular cartilage. 
M. transversus auricule (Fig. 63, 7).—A band about six 
to eight millimeters wide, on the medial convex surface of the 
auricle, between the distal ends of M. levator auris longus (g” 
and M. auricularis superior (£). 
Origin on the medial surface of the concha, just proximac 
of the furrow which corresponds to the antihelix. The muscle 
bridges this furrow, passes distad about two centimeters, and is 
inserted on the auricular cartilage on a line which forms a 
caudal continuation of the line of insertion of the levator auris 
longus (g’). 
Relations.—Outer surface with the levator auris longus 
(g, g ), the auricularis superior (£), and the integument; inne: 
surface with the auricular cartilage. 
Action.—Flexes the scapha mediad on the concha, thus 
enlarging the external opening of the concha. 
M. auricularis externus (Fig. 169, 10; Fig. 64, ~).—Thi: 
consists of small scattered bands of interrupted fibres on the 
convex surface of the auricle, caudad of the transversu: 
auricule. The largest of these bands runs parallel with the 
transversus auricule about five or six millimeters caudad of the 
latter. It has origin on the eminentia conche distad of the 
insertion of the abductor auris longus. Thence the fibres rur 
distad five or six millimeters and are interrupted by an attach. 
ment to the cartilage. Distad the fibres begin again, and the 
muscle runs thence distad. for about one centimeter, the dista
