Expect to pay around 300 for the base unit, and another 100 to have your feet do some of the hard work. Read on for advice on how to use Elite's map systems and route-planning tools. Head back to the first page of this article for the rest of our Elite Dangerous guide.
Striking the patellar ligament with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle. This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L4 in the spinal cord, completely independent of higher centres.he patellar reflex is a clinical and classic example of the monosynaptic reflex arc. There is no interneuron in the pathway leading to contraction of the quadriceps muscle. Instead the bipolar sensory neuron synapses directly on a motor neuron in the spinal cord.
Stretch reflexes are initiated by tapping a tendon, which stretches the muscle the tendon is attached to (the Quadriceps femoris muscle). This stimulates the muscle spindles and causes reflex contraction of the stretched muscle or muscles, which resists further stretching.tretch reflexes are initiated by tapping a tendon, which stretches the muscle the tendon is attached to (the Quadriceps femoris muscle).
