A 54-year-old patient diagnosed with toxic fume exposure presents with symptoms affecting the neurologic system. On inspection of the upper extremities, you notice small, repetitive local contractions of the muscles visible through the skin. Which of the following best describes these types of abnormal muscle contractions? Answers: A-D A Clonus B Tensus muscularis C Asterixis D Fasciculation O
Botulism is a disease that was associated to eating out of cans that had been contaminated by a deadly bacteria. It is an anaerobic bacteria (does not need oxygen to survive). What botulism does is It floods hte area with sodium O prevents the sarcoplasmic reticulum from releasing Calcium O prevent the release of the neurotransmitter acetylcholine prevent the release of the neurotransmitter dopamine
The spinal cord has the motor neurons that control muscle. But who controls those motor neurons? Neurons in the motor cortex control them. There are also other groups of neurons that can command spinal motoneurons. For example, when it comes to controlling our balance and posture, cells from Ventricular Nucleus descend onto spinal motoneurons to control them. They form a tract within the ventromedial pathway called vestibulospinal track
1. What are an afferent neuron and efferent neuron? What are efferent components of the facial nerve and their actions? 2. Under certain circumstances, axons in the peripheral nervous system can regenerate after sustaining damage. Why is axonal regeneration in the central nervous system much less likely? 3. At a healthy myoneural junction, acetylcholine is responsible for stimulating muscle activity. What mechanisms are in place to prevent the continuous stimulation of a muscle fiber after the neurotransmitter is released from the presynaptic membrane?
