a) Cranial out flow consists of branches from III, VII, IX and X cranial nerves.
b) Pre-ganglionic fibers are short and post-ganglionic fibers are long.
c) Acetylcholine is produced at the terminal end of pre-ganglionic fibers.
d) It accelerates peristalsis and micturition
e) It controls body activities during fight or flight response.

• A. a and b

Hint:

Judge each statement a to e on its own and then find the option containing the right pair.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
The parasympathetic system is the rest and digest part of the autonomic nervous system.

Step 2: Check the statements
(a) The cranial outflow runs in nerves III, VII, IX and X, so (a) is true.
(b) Pre-ganglionic fibres are long and post-ganglionic fibres are short, so (b) is false.
(d) It speeds up peristalsis and micturition, so (d) is true.
(e) Fight or flight is controlled by the sympathetic system, so (e) is false.

Step 3: Choose the option
The pair of statements (a) and (d) is offered only in the third option.

Final Answer:
Statements a and d are the correct pair. \[ \boxed{\text{(C) }\text{a and d}} \]
