Absolutely I agree with your viewpoint, and sincere apologies if my additions caused confusion - You are also correct that this Q [probably worth one mark] is adequately answered by your response, which is why I gave you a rep.
I only provide greater detail to my students [apart from TSR] for a few reasons - sorry it will be v difficult for you to understand my unusual style of teaching by reading a few sentences on a web page; however, in a nutshell:-
1. If you look at the first few lines of my post:-
"Yes your answer is correct [rep to follow in a sec]; just to add a little more detail to help you and the person destined to fail [he must be a super-pessimist!
]
for the extra marks in the synoptic Q"
in particular the phrase in bold:-
a) The synoptic Q at A2 has a few marks reserved for info outside the syllabus.
b) There is, in my view, no harm in a gentle intro to material that will appear later in your course [you will learn about nerves/synapses/neurotransmitters at some stage].
c) One of my teaching tactics is to constantly cross-link between different parts of the syllabus cos:-
.....i) It is a great memory retention and recall exercise based on association, and on the principles outlined by Tony Buzan in his excellent books
.....ii) A number of Qs at AS and A2 levels requires the student to draw information from various parts of the syllabus, and this technique is good practice at doing this.
2. I believe in teaching a little more detail than is required cos then what is required becomes a trifle [yummy
- sorry about the pun!]
Apologies once again that my answer was confusing - shame that it is impossible to provide my unique teaching on a web page [sorry if this sounds like blowing my own trumpet, but my student's results speak for themselves]..
Best of luck in your exams, and your reply was not rude but rather very relevant and valid!
