Eye Flashcards
1
Q
Choroid vascular layer
A
Contains multiple layers of vessels that sit within a darkly pigmented stroma
2
Q
Ciliary body
A
Contains smooth muscle fibres that originate on the sclera.
Contraction of these fibres decreases tension on zonular fibres + thickens the lens - focuses lens
3
Q
Cornea
A
Joins the opaque sclera at the limbus corneae
Innervated by the ophthalmic branch of the trigeminal (V) n.
4
Q
Iris
A
Regulates amount of light entering the eye
Contains radial smooth muscle + circumferential smooth muscle.
Both muscles receive parasympathetic + sympathetic innervation
5
Q
Lens
A
Attached to the ciliary processes via zonular fibres
Focuses light onto the retina.
6
Q
Optic nerve
A
Cranial nerve II
7
Q

A
White part of eye - joins the transparent cornea at the limbus corneae
