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.
Which of these is not one of the essential compponents of a reflex arc?
output to upper 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.
A positive finding in an adult represents upper motor neuron disease of the pyramidal tract?
Babinski's reflex
What happens if motor neurons are damaged?
Motor neuron involve the muscles. If they are damaged, then the muscle that they are connected to will not work.
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.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
A reflex arc.
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.
What are the first and last elements in a spinal reflex?
motor neuron and sensory neuron

In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
Which is the correct sequence in a typical reflex?
Receptor ---> sensory neuron----> interneuron (at spinal cord)---->motor neuron---->effector. The Achelles tendon reflex is a good example of how this happens. You do send infromation to the brain in the form of an "incident report" but his is much slower.
Mechanism of reflex arch?
A reflex arch includes a receptor, senory neuron, a ref;ex center composed of interneurons, motor neuron, and effector.
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.
What is an abdominal reflex?
An abdominal reflex is a superficial skin reflex. Its absense indicate an upper motor neuron lesion.
What is the correct arrangement of a reflex arc?
Receptor → Sensory Neuron → Associative Neuron→ Motor division →Effectors
