Brain, glands, motor neuron, movement, muscles, sensory neuron, stimuli the word _belongs in a different group than all of the other words in the list.

The right answer is glands.

All the words here refer to the reflex arc, except the glands.

The glands do not interfere in relfexe. They have rather a link with the vegetative nervous system (sympathetic in particular such as the adrenal glands to secrete adrenaline).

When a stimulus, calling for an immediate response, is perceived by a receptor housed in a part of the body, the nerve impulse propagates on the afferent fibers towards the spinal cord or the brainstem. After the passage through one or more synapses of the motor neurons, the afferent response - in the form of a second nerve impulse - goes to the effector organ (muscle for example) or to the motor centers, upper or lower (medullary nuclei of the spinal cord or central nuclei, muscular tone of the cerebellum, awareness of the cortex, etc.).

Well definitely the answer is Glands.

Explanation:

Well as we know that brain controls movement, so of all the terms listed we can definitely correlate muscle movement with brain and the involvement of sensory and motor neurons here. When ever a stimuli is received by the sensory organs, it is passed by the sensory neuron to the brain and from their the information is carried by the motor neuron to the effector organ like muscle. Glands are group of cells that are involved in secretions when stimulated by any specific hormone.
