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.
The first is the muscle spindles. Located within the muscle fibres they monitor changes in muscle length. The stretch reflex is the bodys involuntary response to an external stimulus that stretches the muscle (5) and causes a reflexive increase in muscular activity. It is the muscle spindles that activate this response. When stretching, it is best to avoid this activating the muscle spindles and the stretch-reflex response, as it will limit motion. Static stretching does not elicit the muscle spindles, allowing muscles to relax and achieve a greater stretch. The other important proprioceptors are the golgi tendon organs (GTO).
