A subluxation can impact which of the following?

A subluxation refers to a misalignment of the vertebrae that can affect the nervous system's function. When vertebrae are misaligned, they can interfere with nerve pathways that communicate with various organs and systems in the body. This disruption can lead to a wide array of health issues, as it may affect the body's ability to function optimally.

The concept in chiropractic care is that every system in the body is interconnected through the nervous system. Therefore, when a subluxation occurs, it can influence not just the immediate skeletal system, but also overall health and organ function. This means that a single adjustment may help restore proper nerve function and communication pathways, potentially leading to improvements in various health conditions.

In contrast, the other options, while they present important considerations in the context of health and fitness, are too narrow. A subluxation does not solely impact the skeletal system or only nerve conduction velocity. Additionally, while muscle growth and strength can be influenced by nerve function and overall health, they are not the primary areas of impact when discussing subluxations in the context of chiropractic philosophy.
