Sensory Neurons:
* Location: Found in the peripheral nervous system (PNS), specifically in sensory organs like the skin, eyes, ears, nose, and tongue. They also exist in internal organs like the stomach and bladder.
* Function: They detect stimuli from the environment (light, sound, touch, temperature, pain, etc.) and convert them into electrical signals. These signals are then transmitted to the central nervous system (CNS).
Motor Neurons:
* Location: Found in the CNS, specifically in the brain and spinal cord. They also extend out into the PNS, where they connect to muscles and glands.
* Function: They receive signals from the CNS and transmit them to muscles and glands, causing them to contract or secrete substances. This results in movement, reflexes, and other bodily responses.
Here's a breakdown:
* Sensory neurons: Carry information *from* the body *to* the brain and spinal cord.
* Motor neurons: Carry information *from* the brain and spinal cord *to* the body (muscles and glands).
Key Point: Sensory neurons and motor neurons work together to create a complete neural pathway, allowing the body to respond to its environment.
