How does reflex occur?

This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response


Does the motor neuron send a signal to or from the muscle fiber?

Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.


What part of the nervous system is responsible for the reflex arc?

The peripheral nerves and the spinal cord. When a reflex starts, the peripheral nerves in the arms or legs send a signal to the spinal cord. Normally that signal is sent on to the brain for processing. In a reflex, the spinal cord itself sends a response back to the arm or leg to move immediately.


How do muscles get signals from the brain?

Brain sends signal through spinal cord to nerves. Nerves contract which muscle to move and sends a message back to the brain. BOOM! Movement.

What is sensor of negative feedback loops?

In negative feedback loops, a sensor is a component that detects a change in a system's internal or external environment. It then sends this information to the control center, which triggers a response to counteract the change and maintain homeostasis. The sensor plays a crucial role in providing feedback that helps regulate and stabilize the system.
