Sample Question 1
Which 3 pairs of muscles control movement of the eye? What do they do individually?

1) Orbicularis oris and orbicularis oculi control eye movement in all directions

3) Deltoid and pectoralis major control eye movement sideways and diagonally

1) Superior rectus and inferior rectus move the eye up and down (specifically --> superior rectus moves eye back and up, inferior rectus moves eye forward and down)2) Lateral rectus and medial rectus move the eye sideways (specifically --> lateral rectus moves eye to the side, and medial rectus moves eye back towards nose)3) Superior oblique and inferior oblique move the eye clockwise and counterclockwise, off the cardinal axes

2) Biceps brachii and triceps brachii control eye movement up and down

Sample Question 2
Which 2 muscles control the size of the pupil to adjust to different light intensities?

1) Ciliary muscle 2) Zonule fibers

1) Retinal muscle 2) Optic nerve muscle

1) Corneal muscle 2) Lens muscle

1) Iris sphincter (circular)2) Iris dilator (radial)

Sample Question 3
What are the 3 specializations of the fovea?

1) Presence of blood vessels 2) Inclusion of upper retinal layers 3) Sparse distribution of photoreceptors (cones)

1) No blood vessels2) No upper retinal layers3) Densely packed photoreceptors (cones)! Rods are at 20 degrees right of fovea -- remember 1942 experiment!
