Unit 3 Discussionmla Format250 Words1 Pick One Of The Four Questions

Pick ONE of the four questions below to answer using both the information learned in Unit 1 and online resources. Answer the question in complete sentences in no more than a single paragraph. Cite at least one source that supports your answer.

Discussion Question Choices

  1. What responses are generated by the nervous system when you run on a treadmill? Include an example of each type of tissue that is under nervous system control.
  2. Meningitis is an inflammation of the meninges that can have severe effects on neurological function. Why is infection of this structure potentially so dangerous?
  3. If a reflex is a limited circuit within the somatic system, why do physical and neurological exams include them to test the health of an individual?
  4. The conscious perception of pain is often delayed because of the time it takes for the sensations to reach the cerebral cortex. Why would this be the case based on propagation of the axon potential?

The nervous system plays a crucial role in coordinating responses to various stimuli and maintaining homeostasis during physical activity, such as running on a treadmill. When an individual runs on a treadmill, multiple responses are orchestrated by the nervous system to support movement, cardiovascular regulation, and muscular activity. Firstly, the central nervous system (CNS), comprising the brain and spinal cord, processes sensory feedback from muscles, joints, and the cardiovascular system to adjust stride, maintain balance, and regulate breathing rate (Karim et al., 2020). For example, proprioceptors in muscles and joints send signals via sensory neurons to the spinal cord, where interneurons relay information to motor neurons that control skeletal muscles, exemplifying nervous control over muscle tissue. Additionally, the autonomic nervous system (ANS) regulates cardiovascular responses, such as increasing heart rate and blood vessel dilation, to meet the metabolic demands of running (Gao et al., 2019). These involuntary responses maintain oxygen delivery and waste removal in tissues. The tissue types controlled by the nervous system during running include skeletal muscles, which move the limbs; cardiac muscles, which adjust the heart rate; and smooth muscles in blood vessels, which regulate blood flow. This integrated response ensures efficient physical performance and metabolic homeostasis. Overall, the nervous system's coordination of neural signals to musculature and organs exemplifies its vital role in supporting dynamic activities like treadmill running.
