Ciliary muscle
Musculus ciliaris
Definition
The ciliary muscle is made up of smooth muscle fibers in the ciliary body, divided into two categories:
Meridional fibers, which are more numerous and insert into the scleral ring.
Circular fibers, less numerous and thinner.
Their action deforms the lens, playing a role in accommodation.
