To determine: The minimum number of neurons required in the simplest reflex.
Introduction: A reflex action is a fast movement of a body part in response to the stimulus. There are various types of reflexes. Simplex reflex is the most basic type of reflex.
To determine: The minimum number of synapse required in the simplest reflex.
Introduction: Synapse is defined as the gap between the nerve endings of the two neurons. The signals are transferred from one neuron to the other through these synapses which release neurotransmitters.
To determine: An example of the simplest reflex.
Introduction: The reflex is an instant and involuntary movement of a body part that occurs in response to the stimulus. There are various types of reflexes. Simplex reflex is the most basic type of reflex.

- Which of the following are essential components of a basic reflex arc? Select all that apply. At least one synapse Motor neuron Effector Sensory neuron Sensory receptorarrow_forwardA reflex arc includes :-a- at least two sets of sequential neuronsb- at least two sequential sets of central synapsesc- at least two types of sensory receptorsd- at least two types of efferent neuronsarrow_forwardPlace the following concepts in the correct order to explain how a reflex works: Target organs , Afferent neuron , Sensory receptor , Interneuron , Motor neuronarrow_forward
- Why is response time in a monosynaptic reflex much faster than response time in a polysynaptic reflex?arrow_forwardGive a labeled illustration of a simple reflex arc with its components of the patella tendon tap reflex/knee jerk reflex.arrow_forwardLabel on the diagram: 1. Muscle spindle 2. Sensory neuron 3. Soma of sensory neuron 4. Dorsal root 5. Dorsal root ganglion 6. Dorsal horn 7. Ventral horn 8. Motor neuron to quad 9. Motor neuron to biceps 10. Excitatory synapse 11. Inhibitory synapse What is the name of this reflex? e20SPm idton, How many neurons are Tap your partner's patellar ligament to test their reflexes and try tapping the belly of the brachioradialis muscle to see what happens. involved?arrow_forward
- What is the physiological function of chemical and electrical synapses between reflexes (eg. a Knee Reflex and jerk reflex).arrow_forwardName one reflex of the body and briefly discuss it and give one example.arrow_forwardNumber the events of a reflex arc from 1 (first event) to 5 (last event). CNS sends output via motor neurons to an effector Sensory neurons bring the stimulus to the CNS The muscle contracts CNS processes and integrates the information Sensory receptor detects the stimulusarrow_forward
