The posterior chamber of the eyeball is found in between the lens and the
Cornea
Cilliary body
Iris
Renina
The visual pigment of the rods is called rhodopsin. It consist of a protein called opsin and a vitamin derivative called retinal
A B C D
Cone cells regenerate half of their pigment about 90 seconds, while rod cells require 5 minutes to regenerate 50% of their bleached rhodopsin t/f because 600 rod cells converge on each bipolar cell and many bipolar cells converge on each ganglion cell. We have the ability to see color in bright light high sensitivity of rod cells in dim light rod cells that concentrate in the macula cone cells that concentrate at the periphery of the retina

A person experiencing pain around the shoulders or neck may actually be having problems with their lungs or diaphragm. This misplacement of the pain by the conscious mind is called
Projection pain
Fast pain, slow pain
Referred pain++ petrichial pian
Pain signals may be blocked by special neruotransmitters in the brain itself. An example of such achemical produced during exercise is
