Structures in Anterior Abdominal Wall

Hi! Attached is a picture of 'Superficial dissection' of Anterior Abdominal Wall from Netter's Atlas

Please try to identify the structures labelled, there are some questions also. Please feel free to answer even if it is presumed to be wrong for 'feedback' from me.

i. The structure labelled 'o' is quite important. Is there any implication if during surgery incision is made through it?

ii. The structures 'P' & 'Q' both are layers of same layer out of the 8 layers of 'Anterior Abdominal Wall '. What are the layers P & Q , is there any clinical significance to these 2 layers?

iii. There is an opening seen as 'R'. What is this opening? which muscular aponeurosis is dragged to produce this opeing in early part of our life. what is the structure which drags this aponeurosis ?

iv. 'S' denotes some structure which gives strength to 'R' opening. What is 'S'

v. 'V' is very important rope like thing, on which integrity of all the strutures around are dependent. what is it?

vi. What is the layer of fascia seen lying over spermatic cord as 'X'? is it the only layer of fascia over the cord, what are the others and how they are derived during early years of life?

vii. List the different types of structures formed by 'M'.

Best of luck in answering this question using your 'GI' knowledge.
