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 = Sense organ; B = Sensory nerve;. C = Ventral horn; D = Interneuron; E = Dorsal horn; F= Motor nerve; G = Effector
- A = Sense organ; B = Sensory nerve ; C = Dorsal horn; D = Interneuron; E = Ventral horn; F = Motor nerve; G = Effector
- A = Effector; B = Motor nerve; C = Ventral horn; D = Interneuron; E = Dorsal horn; F = Sensory nerve; G = Sense organ
- A = Sense organ; B = Motor nerve; C = Dorsal horn; D = Interneurpn; E = Ventral horn; F = Sensory nerve; G = Effector
The Correct Option is B

Concepts Used:
Neural Control and Coordination
Neural System:
Neurons are the most specialised cells in the nervous system of all animals, and they are responsible for detecting, accepting, and conveying numerous types of motives. The neurological system of low-spinal animals like Hydra is incredibly simple, consisting of a network of neurons. When the brain of an insect comprises a vast number of ganglia and neural tissues, it is optimally structured.
Coordination System:
Coordination is the process by which two or more organs work together to accomplish each other's duties. Increased muscle activity increases the supply of oxygen and the demand for energy while we exercise. When we cease exercising, our nerves, heart, lungs, and kidneys all return to normal. As a result, all of the organs' functions are properly integrated in order to conduct the exercise and supply the appropriate conditions while exercising. Similarly, in the human body, the neurological and endocrine systems work together to coordinate all of the organ activities.
