Muscles and glands?

In terms of the nervous system, muscles and glands are given the generic term effector organs. Impulses are picked up from receptors, which then travel to the brain, which sends orders along the motor neurons to these effector organs. In the case of reflex actions, however, the brain is not involved, and the process is done much faster as a result.


What kind of neuron sends a message from the brain to the muscles in a persons arm to control the movement involved in putting clothes on?

There are basically two kinds of neurons- sensory and motor. Motor neurons are responsible for passing on messages from the brain, to the effector muscles, while performing a voluntary action (they also do that for involuntary actions) Sensory neurons on the other hand, detect a stimulus, and pass on the message to the brain, which analyses the information, decides the course of action, and passes on the message back through the motor neuron, to the effector muscles.
