What neurons are involved in a reflex?
3 neurons are included in the reflex arc. They are: Afferent neurons (take the message to the spinal cord) (sensory) Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain) Efferent neurons (takes message to effector) (motor) Not all reflexes have interneurons.
What are the five parts of a reflex arc?
Summarized below are the 5 major components of the reflex arc: 1. Receptor 2. Afferent (sensory) neurons 3. Association neuron 4. Efferent (motor) neurons 5. Effector
What are the three types of neurone involved in a reflex action?
The three types of neurons are sensory(afferant) neurons, interneurons, and motor(efferant) neurons. Sensory, or afferent, neurons send information from the receptor to the central nervouse system. Interneurons, found only in the central nervous system, play the role of interpretting the impulse. The motor, or efferent, neurons send the information from the central nervous system to the effector. Receptor->sensory neuron->interneuron->motor neuron->effector.
What connects the sensory neurons to motor neurons?
What connects sensory and motor neuron is the impulse called interneuron or connector neuron are connected by means of electrical impulse called synape from sensory to motor neuron.
what type of reflex is the knee?
The knee reflex is also called the knee-jerk reflex by tapping the patellar tendon with a reflex hammer. This sends sensory information to the spinal cord at L4 and motor information back to the Quadriceps in the thigh (relaxing the hamstrings). This is reflex requires only two neurons. No interneuron. And so is very rapid. It is important in balance and posture.
A withdrawal reflex employs what neurons?
Withdrawal reflex or flexor reflex employs sensory neuron, interneuron and motor neuron.
Does visceral reflex arcs have two sensory neurons?
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
What neurons are involved in a reflex?
3 neurons are included in the reflex arc. They are: Afferent neurons (take the message to the spinal cord) (sensory) Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain) Efferent neurons (takes message to effector) (motor) Not all reflexes have interneurons.
What reflex has at least one interneuron placed between the sensory and motor neurons?
Polysynaptic Reflex
What connects sensory to motor neuron?
Interneurons(also called relay neuron, association neuron, connector neuron or local circuit neuron) are multipolar neurons that connects sensory neurons to motor neurons.
What is a neuron serving as part of the conduction pathway between sensory and motor neurons?
Interneurons are neurons found within the central nervous system (primarily the brain or spinal cord) that connect sensory (afferent) neurons to motor (efferent) neurons. Often these neurons are part of a polysynaptic reflex arc.interneurons. They are also called association neurons.

What are neurons serve as links between the sensory neurons and the motor neurons?
Interneurons, which make sense--they're the intermediaries. Many interneurons can send simultaneous messages to the brain and motor neurons--this is called a reflex arc.This is the interneuron. It is in the spinal cord. They act as a "go between" the sensory neuron and the motor neuron. They also send information to the brain so that the brain is aware.Reflex arcs do NOT have these interneurons.
What is the pathway called that signals travel along during a reflex?
Sensory neurons which trigger reflexes are called nociceptive neurons. After entering the dorsal root of the spinal cord, the nociceptive neuron branches into two terminals: one terminal synapses with an interneuron - a localised neuron which is located entirely within the grey matter of the spinal cord, and this in turn synapses with a motor neuron which then triggers the fast reflex action. The reflex is initiated solely within the spinal cord & doesn't involve the brain at all, but at the same time, the second branch of the nociceptive neuron synapses with a sensory neuron which goes to the brain; the brain then registers the sensation of pain, and can also initiate further motor action if necessary.
Describe the path an impulse would take for a reflex reaction?
Sensory neurons are responsible for sending the initial message. First to a local neuron, which in turn communicates with a motor neuron. Therefore it is causing a reflex.
