Motor neurons

Definition

Motor neurons are nerve cells that transmit signals from the central nervous system (brain and spinal cord) to muscles, glands, and other effector organs. They play a crucial role in controlling voluntary movements and regulating bodily functions.

Sensory Neurons: Sensory neurons are nerve cells that transmit information from sensory receptors (e.g., eyes, ears, skin) to the central nervous system. They allow us to perceive and sense the world around us.

Interneurons:

Interneurons are nerve cells located within the central nervous system. They act as connectors between sensory and motor neurons, allowing for communication within the nervous system.

Reflex Arc: A reflex arc is a neural pathway that controls involuntary reflex responses. It involves sensory neurons detecting stimuli, interneurons processing the information, and motor neurons sending out an immediate response without conscious thought.
