<span>In the "all or none" law of muscle contraction, it states that when the stimulus applied exceeds threshold then the the nerve sending signals to a few muscle fibers will give a complete response; contraction. Graded response is dependent on how many motor units have been recruited. The more motor units, the greater the force in the contraction.</span>

sleet_krkn [62]

In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.

The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.

Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.

  • The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).

  • Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.

  • On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).

Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.
