and is also attached to inner of superior curved line of 

 occipital behind. Laterally it is lost over temporal fascia, 

 where it gives origin to attrahens and attollens aurem. 



AURICULAR REGION. 



Attrahens aurem : fore part of epicranial aponeurosis(F) 

 fore part of helix, and eminence on back of pinna, corre- 

 sponding to the fossa of the antihelix(x) (Temporal branch 

 of facial). [Very little ; draws ear forward.] 



Attollens aurem: epicranial aponeurosis(p) cranial surface 

 pinna, corresponding to fossa of antihelix(T) (Temporal 

 branch of facial). [Very little ; raises ears.] 



Eetrahens aurem: root of mastoid process(A) lower part 

 of cranial surface of concha(A) (Posterior auricular). [Very 

 little ; draws ear back.] 



PALPEBRAL REGION. 



Orbicularis palpebrarum : Sphincter of eyelids. Orbital part. 

 Internal angular process of frontal, internal tarsal ligament, 

 nasal process of superior maxilla(F). Palp ebral part. Internal 

 tarsal ligament(F) external tarsal ligament(F) (Facial). Ciliary 

 part. Marginal portion of preceding ; lies along bases of eye- 

 lashes. [Closes eye ; maintains apposition of eyelids to 

 eyeball.] 



Tensor tarsi (Horner's muscle) : ridge of os lachrymalis(F) 

 joins with ciliary part of orbicularis internal to the 

 punctum(p) (Facial). [Acting with orbicularis empties lach. 

 rymal sac.] 



Internal tarsal ligament (tendo oculi) is attached to ridge on 

 nasal process of superior maxilla in front of lachrymal 

 groove, divides into two slips, each joining the inner end of 

 the corresponding tarsal cartilage. 



External tarsal ligament, connects the tarsal cartilages to 

 outer part of orbit. 



Corrugator supercilii : inner part of superciliary ridge of 

 frontal(F) under surface of orbicularis, opposite middle of 

 orbital arch(p) (Facial). [Wrinkles forehead vertically.] 



ORBITAL REGION. 



Levator palpebrse superioris : inferior surface of small wing 

 of sphenoid, anterior to foramen opticum and external to 

 superior oblique(x) anterior part of superior tarsal plate, 

 also superiorly to join orbicularis and inferiorly to superior
