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.

- Complete the components in a polysynaptic reflex arc in the order that they are activated. Then briefly describe the function of each. #1 #2 #3 #4 #5arrow_forwardWhen describing the reflex arcs and the neural pathways involved we often limit ourselves to the nerves carrying information from the muscle or tendon to the spinal cord and back. However, it should be clear from our ability to feel the tendon tap as well as the results from the Jendrassik’s maneuver test that it isn’t this simple. What other neural connections must be present ?arrow_forwardList the five steps in a reflex arcarrow_forward
- Visceral reflex arcs differ from somatic in which of the following ways? the number of sensory neurons the use of Ach as their only neurotransmitter the use of the motor cortex to regulate their effectors the number of motor neurons reliance on unipolar neurons to transmit their signalsarrow_forwardDiscuss the Hering-Breuer reflex and its importancearrow_forwardwhat is typical reflex pathway containing three different nerve cell types. What function does the respective cell have?arrow_forward
- 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
- Give a labeled illustration of a simple reflex arc with its components of the patella tendon tap reflex/knee jerk reflex.arrow_forwardWhy is response time in a monosynaptic reflex much faster than response time in a polysynaptic reflex?arrow_forwardWhy is it important to study reflexes? What clinical applications might these have? Describe a simple reflex arc.arrow_forward
