You're in the middle of a meeting at work, but your mind keeps drifting to the parent-teacher conference you have tonight ... and the car you have to pick up at the shop on the way home ... and how you wish you hadn't skipped lunch because the rumbling in your stomach is driving you nuts. Then, suddenly, you're back in the moment, hoping nobody noticed your brief "departure."
It may seem as if your brain is always on the go. And it is. The brain not only controls what you think and feel, how you learn and remember, and the way you move and talk, but also many things you're less aware of - such as the beating of your heart, the digestion of your food, and yes, even the amount of stress you feel. Like you, your brain is quite the juggler.
Motor neurons manufacture neurotransmitters, specifically acetylcholine, which is responsible for transmitting signals from the neurons to muscles, enabling movement.
Motor neurons are neurons which carry impulses from the Central Nervous System to muscles or glands. When an action potential is conducted by a motor neuron a muscle contracts or a product is released from a gland.
Efferent neurons are responsible for carrying signals away from the central nervous system to muscles or glands. They are involved in transmitting motor commands from the brain to the muscles to produce movement, rather than acting as the primary connector between other neurons.
Peripheral nervous system (PNS) motor neurons are responsible for controlling voluntary movements of skeletal muscles. They receive signals from the central nervous system (CNS) and transmit them to the muscles to initiate movement. PNS motor neurons are essential for activities like walking, talking, and grabbing objects.
Lower motor neurons are referred to as the final pathway because they are the last stage in the neural circuitry that conveys motor commands from the central nervous system to the muscles. They directly innervate the muscles and are responsible for initiating muscle contraction and generating movement.
Motor neurons belong to the nervous system, specifically within the spinal cord and brain. They are responsible for transmitting signals from the central nervous system to muscles, facilitating movement. These neurons play a crucial role in the peripheral nervous system as well, connecting the spinal cord to skeletal muscles.
Messages are transmitted from your spinal cord to muscles in your hands through motor neurons. These motor neurons carry signals from the spinal cord to the muscles, causing them to contract and perform the desired movement. The process involves electrical impulses traveling along the motor neurons to trigger muscle movement.

Sensory information concerning position and balance motor neurons that control skeletal muscles travel over proprioceptive fibers. These fibers are responsible for conveying information about the body's position, movement, and orientation to the central nervous system.
Motor neurons are responsible for transmitting signals from the central nervous system to muscles or glands, allowing for voluntary movement or secretion. On the other hand, sensory neurons detect information from the external environment or the body and transmit it to the central nervous system, enabling us to perceive sensory stimuli such as touch, temperature, pain, or sound. In summary, motor neurons control movement and actions, while sensory neurons provide information about the external world to the brain.
Motor neurons within the peripheral nervous system carry signals from the brain and spinal cord to the skeletal muscles, while muscle fibers receive and respond to these signals, leading to muscle contraction and movement. Motor units, comprising a motor neuron and the muscle fibers it innervates, work together to control muscle movement output.
