1. With regard to the orbit:
a. the largest portion of the medial orbital wall is made
up of lacrimal bone
b. lamina papyracea separates the orbit from the
ethmoidal air cells
c. inferior oblique originates from the maxillary bone
d. trochlear, a small piece of bone in the roof of the orbit
is located 4 mm from the orbital margin
e. the lesser wing of sphenoid forms part of the medial
wall
2. The ciliary ganglion:
a. is found 3 cm in front of the annulus of Zinn
b. is located lateral to the ophthalmic artery
c. is situated between the lateral orbital wall and
the lateral rectus muscle
d. receives three roots
e. if damaged causes mydriasis of the ipsilateral eye
3. The ciliary ganglion receives the following branches:
a. a sensory root from nasociliary nerve
b. a sensory root from lacrimal nerve
c. a motor root from the inferior oculomotor nerve
d. a motor root from the trochlear nerve
e. sympathetic root from the plexus around the internal
carotid artery
4. The short ciliary nerves:
a. arise from the ciliary ganglion
b. contain both sympathetic and parasympathetic fibres
c. enter the globe near the vortex veins
d. travel anteriorly between the scleral and the choroid
e. contains fibres that are non-myelinated
5. The ciliary body:
a. receives equal innervation from parasympathetic
and sympathetic nerve fibres
b. contains striated muscle fibres
c. contains mainly radial muscle fibres
d. when contracted opens up the trabecular meshwork
e. accumulates connective tissue with age
