Answer (Click to Show Hidden Text)

Anterograde amnesia is more common is characterised by being unable to form memories after trauma and Retrograde amnesia is the opposite, being unable to recall memories before trauma

Correct. Your turn.

Because this is dead, I'll pick it up. God knows I need the practice.

Describe alpha-gamma coactivation and the identify the roles of two neurons involved in it *i hope this is a hard one hehe *

I doubt this will ever show up on a test tho..*except for mine *

No idea what this was but I think I understand after searching at least a hundred sites for a clear answer :p (Click to Show Hidden Text)

Alpha-gamma coactivation is when a muscle/extrafusal fibers contract when an [u]Alpha Motor Neuron[/u] tells it to, and the spindles/intrafusal fibers also contracts when a [u]Gamma Motor Neuron[/u] tells it to at the same time by the same signal.

Yes! Your turn! This occurs within the muscle spindle, which are stretch receptors, which are a type of mechanorecetpors, and hence related to our anatomy test even though it doesnt seem like it at all !

Oh thanks for that extra bit of info

Name and describe all the different types of color blindness.

Malfunctioning/missing red cone: protanomaly/protanopia. 
Malfunctioning/missing green cone: deuteranomaly/dueternopia. 
Malfunctioning/missing blue cone: tritanomaly/tritanopia. 
Only one functioning cone: cone monochromacy. 
Total colorblindness (no functioning cones): achromatopsia.
