Answer:
B. axon hillock
Explanation:
The axon hillock is the junction where the cyton connects with the axon. There is only one axon hillock in the neuron and it is a triangular depression of cell boy to the axon. The axons receives impulse from cyton carry to the different parts of the body. The axon hillock is also called initial segment. Because action potential starts here.
Myelin sheath is the cover or layer around the axon and helps in saltatory movement of impulse. The propagation of impulse is fast in myelinated neurons than the non-myelinated neurons.
The neurolemma is the neural membrane of the neurons. It is like the plasma membrane of the cell. The outer covering of neurons is called neurilemma.
Axon collateral is the end of the axon where axon terminals arise. They carry impulse and transmit to the synapse.
Answer: The advancement in the science and technology also comes with some of the risks which needs to be maintained at the time of surgery.
Explanation:
The fluoroscopy involves the use of X-rays, a form of ionizing radiation which increases the chances of radiation induced cancer.
Though this risk depends on the risk length of procedure and intensity of rays.
The higher intensity of the rays can also cause burns on the skin which can be equivalent to the sun burns.
The brightness of the screen is also introduced so that the patient is exposed to less intensity of rays.
