MEDICAL PHYSIOLOGY

Detailed explanation-1: -The motor neurons release a chemical, which is picked up by the muscle fibre. This tells the muscle fibre to contract, which makes the muscles move. Neurons carry messages from the brain via the spinal cord. These messages are carried to the muscles which tell the muscle fibre to contract, which makes the muscles move.

Detailed explanation-2: -The combination of the nervous system and muscles, working together to permit movement, is known as the neuromuscular system. If you want to move part of your body, a message is sent to particular neurons (nerve cells), called upper motor neurons.

Detailed explanation-3: -Sensory nerves carry signals to your brain to help you touch, taste, smell and see. Motor nerves carry signals to your muscles or glands to help you move and function.

Detailed explanation-4: -Overall, motor neurons (or motoneurons) comprise various tightly controlled, complex circuits throughout the body that allows for both voluntary and involuntary movements through the innervation of effector muscles and glands. The upper and lower motor neurons form a two-neuron circuit.

Detailed explanation-5: -Your eyes, ears, tongue, nose and the nerves all over your body take in information about your environment. Then nerves carry that data to and from your brain. Different kinds of neurons send different signals. Motor neurons tell your muscles to move.
