Simple reflex arc diagram. The Reflex Arc | Components, Types, Importance & Summary The reflex arc of this reflex action is simple. The muscle spindle gets excited when the muscle is stretched. The nerve impulse thus generated is carried by the sensory neuron to the spinal cord. Here, the alpha motor neuron is excited by the sensory neuron. The axon of motor neuron excites the muscle and causes it to contract. PDF 1. The diagram below shows a nerve pathway in an animal. € 1.

The reflex arc is the neural pathway that begins with a sensory neuron at a receptor (e.g., a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle), and as mentioned above, it has following parts: 1. A receptor, which receives stimulus from the surroundings. 2. Afferent or sensory nerve, which takes a sensory impulse to the ...
