A ____ sends a message from the brain to the muscle
A
neurotransmitter
B
muscular dystrophy
C
muscle tension
D
motor neuron
Explanation: 

Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.

Detailed explanation-2: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.

Detailed explanation-3: -When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

Detailed explanation-4: -Motor neurons are also known as efferent neurons, meaning they carry information from the CNS to muscles, and other peripheral systems such as organs and glands. This contrasts with afferent neurons, or sensory neurons, which carry information from sensory organs and tissues back to the CNS.

Detailed explanation-5: -Motor neurons are crucial for voluntary and involuntary movements. They allow the brain and spinal cord to communicate with muscles, organs, and glands all over the body. They send information away from the central nervous system to the muscle, organ, or gland that needs to react.
