This observation may indicate that the patella is responding when its reflexes are tested and that those responses are being strengthened by other parts of the spinal cord that are not usual, indicating diversion. The patellar reflex indicates that there is activity in the L<span>2, L3, and L4 segments of the </span><span>spinal cord.</span>

Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
<span><em><u>SOMATIC NERVOUS SYSTEM</u></em>
The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions.
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions. </span>
From the sensory organ received by the sensory neuron the message is sent to the brain and then back to the motor neuron to the muscle or organ responsible.
