What is the proper order of a spinal reflex?
In order, the five parts of a reflex are sensor, sensory neuron, control center, motor neuron, and muscle. These five parts work as a relay team to take information from the sensor to the spinal cord or brain and back to the muscles.
What is the sequence of neurons in the spinal reflex?
Reflex arcs Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).
What is the correct order of the stimulus response pathway?
Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.
What is the pathway of reflex action?
👉 For more insights, check out this resource.
The anatomical pathway of a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve. Most reflexes have several synapses in the reflex arc.
What are the 6 stages of the reflex arc?

Reflex actions
- Receptor in the skin detects a stimulus (the change in temperature).
- Sensory neurone sends impulses to relay neurone .
- Motor neurone sends impulses to effector.
- Effector produces a response (muscle contracts to move hand away).
Which one of the following represents the correct sequence for reflex are?
The correct answer is Receptor → Sensory neuron → Spinal cord → Motor neuron → Muscle. The correct sequence of the components in a reflex is the Receptor → Sensory neuron → Spinal cord → Motor neuron → Muscle.
Which of the following is the correct sequence in a simple spinal reflex arc?
Which of the following is the correct sequence in a typical reflex?
Which of the following is the correct sequence in a typical reflex arc: Receptor, afferent neuron, efferent neuron, integration center, effector.
What is reflex path?
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
What are reflex actions Class 5?
Reflex action is an involuntary,unconscious action by the body in response to external stimuli. Reflex action is an immediate actiongenerated by the body in response to the environment without involvement of the brain. *As the stimulus is fired, impulses are carried out at an instance to spinal cord.
What are the five elements of a reflex arc?
The reflex arc consists of 5 components:
- sensory receptor.
- sensory neuron.
- integration center.
- motor neuron.
- effector target.
