Ciliary ganglion: Function, Fibres in ciliary ganglion
- Ciliary ganglion is a parasympathetic ganglion located in the posterior orbit.
- It measures 1–2 millimeters in diameter and contains approximately 2,500 neurons.
Fibres in ciliary ganglion:
- Three types of nerve fibers run through the ciliary ganglion:
1. parasympathetic fibers
- Only parasympathetic fibers form synapses in the ganglion
- The other two types of nerve fibers simply pass through
Function of ciliary ganglion:
- Ciliary nerve innervates two muscles
constricts the pupil, a movement known as Miosis.
Releasing tension on the , making the lens more convex, also known as accommodation
- Both of these muscles are involuntary – they are controlled by the autonomic nervous system.
