A reflex arc is a nerve pathway in the body of humans and some animals that connects certain muscle groups to others, without involving the brain. These sorts of pathways primarily control involuntary movements in response to some sort of stimulus.
Answers. Best Answer: A reflex arc refers to the neural pathway that a nerve impulse follows. The reflex arc typically consists of five components (3): 1. The receptor at the end of a sensory neuron reacts to a stimulus. 2.The sensory (afferent) neuron conducts nerve impulses along an afferent pathway towards the central nervous system (CNS). 3.The integration center consists of one or more synapses in the CNS. 4. A motor (efferent) neuron conducts a nerve impulse along an efferent pathway from the integration center to an effector.he reflex arc typically consists of five components (3): 1.
