It's a thought in my brain, but at the same time, it's busy secreting acetylcholine and doing all sorts of other things as it makes its way from the motor cortex down through the nerve fibers in the arm.
Es un pensamiento en mi cerebro, pero a su vez, es acetilcolina ocupada segregando y haciendo todo tipo de cosas conforme recorre la corteza motriz hacia las fibras nerviosas del brazo.
