AP PSYCHOLOGY

Detailed explanation-1: -Different neurons have different jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move.

Detailed explanation-2: -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-3: -Motor neurons are a specialized type of brain cell called neurons located within the spinal cord and the brain. They come in two main subtypes, namely the upper motor neurons and the lower motor neurons. The upper motor neurons originate in the brain and travel downward to connect with the lower motor neurons.

Detailed explanation-4: -Axons from these sensory neurons extend to the spinal cord, where they connect to the motor neurons that establish connections with (innervate) the quadriceps. The sensory neurons send an excitatory signal to the motor neurons, causing them to fire too.

Detailed explanation-5: -Motor neurons carry messages away from the brain to the rest of the body.
