membrane of the corp. ciliare. The insertion of this muscle into the 
basement membrane lies slightly more towards the cornea than the 
insertion of Brücke’s muscle. The two parts of the tensor chorioideae 
are separated from Crampron’s muscle by the plexus ciliaris. 
When the eyesplit in the basement membrane has been cut into, 
a muscular fascicle develops in the spaces of Fontana close against 
Müurer’s musele. We now turn away from the horizontal plane and 
first come upon the place of insertion. The muscular fibers terminate 
in a tendon, which bends round the compartment of CRAMPTON’s 
muscle, first in conjunction with Möürrer’s muscle and afterwards 
by itself, and subsequently reaches the inner-lamella of the cornea 
where the lig. pectinatum takes its origin. 
In further sections we see Mürrer’s muscle grow thinner and its 
tendon elongate in relation to the thinning out of the muscular 
tissue, ultimately disappearing entirely. The new muscular fascicle 
has now in part replaced Mürrer’s muscle and partly juts out into 
the spaces of Fontana. . 
Hereafter the structure of Crampton’s muscle is intensified. 
Bricke’s muscle shrinks and reduces its place of origin on the 
sclera, thus making room for the new muscular fascicle. Just where 
Mörrer’s muscle decreases in size and disappears, this new muscular 
fascicle imparts twice running a considerable part of its muscular 
fibers to the basement membrane, which fibers conseqnently perform 
the function of tensor chorioideae. 
The rest, by far the majority of the muscular fibers, have their origin 
on the sclera, between that of the muscle of Brücke and that of 
CRAMPTON.
