Faking being sick for a secondary gain other than attention

Mallingering

-the DDx name sounds like a crime, and this is like a crime

6

What is an organophosphate

decreases the degradation of Ach
therefore, ↑ Ach, and ↑ M + N stimulation

Atropine can only help with the M part

7

What medicine can reverse the M and N overdose effect of organophosphate poisoning

PraLIDoxime

The garbage LID closing near the fumes in sketchy

8

I cant stress this enough, know your cosros

COS3ROSI2J3H for CN exit

9

1- What forearm muscle does the radial nerve pierce through

2- where on hand is radial nerve

1- Supinator

2- superficial radial nerve is posterior thumb (exactly where your jean button scar is)

11

What does a regenerating neuron look like
