Question

Quizplus · Accepted Answer

The length of axons can vary widely, with some being only a few thousandths of an inch long, while others can extend up to 3 or 4 feet. This wide variability allows for efficient communication between neurons across the brain and body. Option A is incorrect because while some axons may be several feet long, this is not true for most axons. Option B is incorrect because while some axons may be this length, this is not true for most axons. Option D is incorrect because the length of an axon is not affected by whether muscles are stretched or clenched.
