The sclera protects from large and small particles and provides a connection for extrinsic muscles. The middle vascular tunic consists of three eye structures: choroid coat that helps to consumeexcess light, this is why the inside of the eye is dark and the ciliarry body which createsthe ciliary muscles and processes, and the iris which has smooth muscle controls the pupil size and also the colored part of the eye. The inner nervous tunic contains the retina andthe visual receptor cells. This portion of the eye is made of different cell types like the nerve cell.
