Ach binds to the na+ channels :frown:


No .-. AcH binds onto ach receptors in the post synaptic and post ganglionic membrane .-.
What does everyone think 70/100 will equate to in UMS ?
Can you believe I was looking for the word imprinting(which I forgot during the exam) and then it came back to me when i left the school gates.
Anyone doing a unofficial mark scheme

I hated the final section on the brain and nicotine
