Knee-jerk reflex. All reflex actions occur via a reflex arc. The diagram below illustrates a simple monosynaptic reflex arc. Label the components of the knee-jerk reflex arc in the diagram: Dorsal root ganglion Motor neuron Muscle spindle Patellar tendon Quadriceps muscle Sensory neuron Stimulus Ventral horn

Structurally, the simplest reflex is the ________ reflex Reciprocal Golgi tendon Knee-jerk Alternating Withdrawal
Sri K.
In the knee-jerk reflex, $a .$ spinal interneurons inhibit the motor neuron of the antagonistic muscle. $b$. activity in the stretch receptor neuron causes contraction of the leg flexor muscles. $c .$ the cell body of the motor neuron is in the dorsal horn of the spinal cord. $d$. action potentials in the sensory neuron release inhibitory neurotransmitter onto the motor neurons. $e .$ the sensory neuron forms a monosynaptic loop with the motor neuron to the antagonistic muscle.
