Which of the following is INCORRECT about the "reverse myotatic reflex"?Group of answer choicesit causes inhibition of alpha motor neurons to the affected muscleit is triggered by excitation of Golgi tendon organ afferentsit involves activation of a spinal interneuronit is not a monosynaptic pathwayit is activated primarily by changes in muscle length

The “reverse myotatic reflex” is best described as follows:Group of answer choicesthe muscle spindle afferent is activated by muscle tension leading to a polysynaptic reflex in the spinal cord which inhibits the motor neuron to the antagonist musclethe Golgi tendon organ afferent is activated by muscle length leading to a monosynaptic reflex in the spinal cord which inhibits the motor neuron to the same musclethe Golgi tendon organ afferent is activated by muscle tension leading to a polysynaptic reflex in the spinal cord which inhibits the motor neuron to the same musclethe muscle spindle afferent is activated by muscle tension leading to a polysynaptic reflex in the spinal cord which inhibits the motor neuron to the same musclethe Golgi tendon organ afferent is activated by muscle tension leading to a monosynaptic reflex in the spinal cord which excites the motor neuron to the same muscle

Which of the following best describes the monosynaptic pathway of the myotatic reflex?Group of answer choicesthe muscle spindle afferent axon enters the spinal cord and synapses onto an interneuron which then synapses onto an alpha motor neuronthe muscle spindle afferent axon enters the spinal cord and synapses onto an alpha motor neurona nociceptor afferent axon enters the spinal cord and synapses onto an interneuron which synapses onto an alpha motor neuronthe Golgi tendon organ afferent axon enters the spinal cord and synapses onto an alpha motor neuronthe muscle spindle afferent ending synapses directly onto an extrafusal muscle fibre

Stimulation of the Golgi tendon organs result in which of the following changes in the reflex arc?Multiple ChoiceStimulation of a stimulatory interneuronStimulation of an inhibitory neuronDecreased action potentials in alpha motor neuronsContraction of skeletal muscle fibersBoth "stimulation of an inhibitory neuron" and "decreased action potentials in alpha motor neurons" are correct.

Spinal reflexes must have all the following EXCEPT:Question 10Answera.Interneuronsb.Terminal effectorsc.Motor neuronsd.Sensory neuronse.Peripheral receptors
