Question

1. what is referred to as the blind spot?

○ macula
○ retina
○ optic nerve
○ fovéa

1. define sub/luxation.

○ partial joint dislocation
○ vertebral rupture
○ joint compression
○ joint fusion

Explanation:

Question 23

The blind spot in the eye is the area where the optic nerve exits the retina. There are no photoreceptor cells (rods or cones) here, so light falling on this area is not detected. The macula is a region for sharp central vision, the retina is the light - sensitive layer, and the fovea is a part of the macula with high visual acuity. So the blind spot is related to the optic nerve.

Subluxation is defined as a partial dislocation of a joint. Vertebral rupture is a different condition involving damage to the vertebra, joint compression is pressure on a joint, and joint fusion is the joining of two bones in a joint, which is not subluxation.

Answer:

optic nerve
