Question

The following diagram indicates the reflex arc. Identify the parts labelled as A, B, C, D, E, F and G. Choose the correct option.

• A. A = sense organ; B = sensory nerve; C = dorsal horn;D = interneuron; E = ventral horn; F = motor nerve; G = effector
• B. A = sense organ; B = sensory nerve; C = ventral horn; D = interneuron; E = dorsal horn; F = motor nerve; G = effector
• C. A = effector; B = motor nerve; C = dorsal horn; D = interneuron; E = ventral horn; F = sensory nerve;G = effector
• D. A = effector; B = motor nerve; C = ventral horn;D = interneuron; E = dorsal horn; F = sensory nerve;G = sense organ

Answer 1

The correct option is A A = sense organ; B = sensory nerve; C = dorsal horn;D = interneuron; E = ventral horn; F = motor nerve; G = effector

Labelling of the given diagram is as follows:
A = sense organ; B = sensory nerve; C = dorsal horn; D = interneuron; E = ventral horn; F = motor nerve; G = effector


So, the correct answer is option 'a'.
