Question

which of the following is/are a component of all spinal reflex arcs? check all that apply receptor afferent neuron interneuron integrating center efferent neuron

Explanation:

A spinal - reflex arc is the neural pathway involved in a spinal reflex. The basic components of all spinal - reflex arcs include a receptor that detects the stimulus, an afferent neuron that transmits the sensory information to the central nervous system, an integrating center (which can be a single synapse or a more complex network of neurons in the spinal cord), an efferent neuron that carries the motor command away from the central nervous system, and an effector that produces the response. While interneurons are present in many spinal - reflex arcs, some simple reflex arcs (like the knee - jerk reflex) are monosynaptic and do not have interneurons.

Answer:

Receptor, Afferent neuron, Integrating center, Efferent neuron
