Origin and insertion end approximately in the same radial section, 
from which it appears that the insertion is much longer than the 
place of origin. The muscular fascicle is somewhat fan-shaped, 
diverging from origin to insertion. The muscular fibers remotest 
from the horizontal plane do not run quite radially, but divert 
slightly in the direction of the horizontal plane. The course of the 
muscular fibers nearest to the horizontal plane is initially diverting 
from the radial direction towards the perpendicular of the horizontal 
plane. Thereafter they curve in temporal direction, parallel to the 
remoted muscular fibers. In fig. 1 we also observe a curvature of 
the muscular fibers and likewise the fan-shape of the muscular fascicle. 
Now let us consider the course of the muscular fascicle in a 
radial plane, vertical to the sclera. The most lateral fibers, — closest 
to the sclera — proceed linearly from the origin to the insertion. 
The fibers which help in walling off the spaces of Fontana run in 
a curve, viz. from the origin first perpendicularly to the sclera, then 
curving round in the direction of the insertion.

Among these curving fibers there are a few which run along a 
straight line from the place of insertion to the basement membrane. 
They extricate themselves from the other fibers at the place where 
the latter change their course, and sometimes in succession where 
Mürrer's muscle ceases to exist and the muscular fascicle takes its 
origin on the sclera. 
In fig. 5 the points in the normal corpus ciliare have been marked 
which in a number of succeeding radial sections have been con- 
nected by lines. We here give an explanation of the signs used:
