When the knee-jerk reflex is evoked by tapping below the kneecap, the first event after the patellar tendon is struck is:Group of answer choicesextension of the legactivation of muscle spindlesrelease of neurotransmitter from a sensory axon ending in the spinal cordexcitation of a spinal motor neuroninhibition of a spinal motor neuron

Select all that applyChoose all the components of the patellar reflex.Multiple select question.Two interneurons in the spinal cord.A sensory neuron with stretch receptors in the quadriceps femoris muscle group.A motor neuron.A sensory neuron with pain receptors in the patella.

The knee-jerk reflex involves which of the following?Multiple ChoiceSensory and motor neuronsSensory neuron, interneuron, and motor neuronSensory neuron, motor neuron, and inhibitory interneuronsSensory neuron and interneuronThe brain

What is the purpose of the patellar reflex?Multiple choice question.remove body parts from the painful stimulusprevent too much tension on a musclehelp maintain posture

Question 191 ptsIf a sudden painful stimulus is applied to one of the limbs, which of the following is LEAST likely to follow:Group of answer choicesa rapid flexing of the affected limba rapid extension of the contralateral limbactivation of A-delta nociceptor axons which trigger reflex responsesa rapid flexing of the contralateral limbactivation of C-fibre nociceptors which give rise to a painful sensation that outlasts the stimulus PreviousNext

If you decide to "snap your fingers," the first neurons to be stimulated are theMultiple Choicesensory neurons in the prefrontal area.motor neurons in the primary motor area.sensory neurons in the primary somatosensory area.motor neurons in the premotor area.
