In the following flow diagram, identify the correct labelling (A and B). 
(i) A is the afferent nerve fibres transmit impulses from tissues/organs to the ANS
(ii) B is the efferent fibres transmit regulatory impulses from the CNS to the concerned peripheral tissues/organs.
(iii) A is the afferent nerve fibres transmit impulses from tissues/organs to the CNS.
(iv) B is the afferent fibres transmit regulatory impulses from the CNS to the concerned peripheral tissues/organs.
A = afferent fibres → carry impulses from organs to CNS/ANS → (i) correct
B = efferent fibres → carry impulses from CNS to effectors → (ii) correct
(iii) also describes afferent correctly ✔
(iv) is incorrect because it wrongly labels afferent for outgoing impulses
