When an action potential is generated within a motor neuron, . When an action potential is generated within a motor neuron, . all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract

every muscle cell of the motor unit is stimulated to contract.

Explanation:

Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

Action potentials generates the nerve impulse in a motor neuron.

When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.

slitherio is the original. its the best friend of all middle schoolers. the man you can count any time you have some free time. slitherio is the guy you hang with while you're in the computer lab suppose to be doing "research or whatever". slitherio isn't just a game but a friend.

wormaxio is just a fake trying to squeeze its way into the friend group. trying to pretend its cool and your best pal but how long has it really been there for you, really. it only wants you as friend to boost its social status. wormaxio is just annoying fake pleb. no offense

you and have a wonderful day
