What occurs during the reflex arc.?
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
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 component of the reflex arc determines the response to a stimulus?
The component that determines the response to a stimulus in a reflex arc is the interneuron. This neuron receives the sensory input from the sensory neuron, processes the information, and then sends signals to initiate the appropriate motor response via the motor neuron.
Can reflex action be carried out without the involvement of neuron?
No.
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.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
A reflex arc.
What reflex does a a sensory neuron synapses directly on a motor neuron?
Monosynaptic reflex
A withdrawal reflex employs what neurons?
Withdrawal reflex or flexor reflex employs sensory neuron, interneuron and motor neuron.
Why are reflex actions very fast?
The impulse in a reflex action goes directly from the sensory neuron to the inter neuron to the spinal cord, which allows for faster actions.
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.

What are the first and last elements in a spinal reflex?
motor neuron and sensory neuron
Which reflex arcs contain no association neuron?
The patellar reflex is an example of a 2-neuron reflex arc. It has 1 sensory neuron and 1 motor neuron. It does not contain an association neuron and so is considered the most simple reflex in humans.
Is the brain involved in a reflex arc?
yes brain i s involved in reflex actions as it makes a pathway for sensory neuron to connect with and brain then directs the motor neuron to take a particular action which is given by effector !(muscles)
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
What structure is the sensory neuron of spinal reflex arc?
nervus sestem
What are the five parts of a reflex?
Five parts of a reflex arc are the receptor, sensory neuron (afferent), integration center, motor neuron (efferent), and effector.
