Question #663

Lateral rectus



Lateral rectus arises from the lateral margin of the tendinous ring as well as the greater wing of the sphenoid bone and passes anteriorly to insert into the sclera on the lateral aspect of the eyeball. On contraction the eye is abducted.

Lateral rectus is the only muscle supplied by the abducent nerve.

The ciliary ganglion lies medial to lateral rectus while the lacrimal gland lies lateral to the muscle. Levator palpebrae superioris splits the lacrimal gland into orbital and palpebral parts.
