| It attacks motor neurones in the spinal cord and lower brain, which transmit signals from the brain to the voluntary muscles throughout the body. |
| The voluntary muscles are regulated by the parts of the brain known as the cerebral motor cortex and the cerebellum. |
| It blocks the function of the axons, making the voluntary muscles unusable. |
| Nicotinic receptors are located on sympathetic ganglia and voluntary muscles. |
| The powerful venom acts on the victim's voluntary muscles, paralysing the muscles required for body movement and breathing. |
| Not all voluntary muscles are equally sensitive to tubocurarine, and fortunately the respiratory muscles are the most spared. |
