Verified step by step guidance

Step 1: Understand the role of neurons in the nervous system. Neurons are specialized cells that transmit signals throughout the body. There are three main types of neurons: sensory neurons, interneurons, and motor neurons.

Step 2: Review the function of sensory neurons. Sensory neurons are responsible for transmitting signals from sensory receptors (e.g., skin, eyes, ears) to the central nervous system (CNS). They do not directly activate muscles.

Step 3: Examine the role of interneurons. Interneurons are found within the CNS and act as connectors or relay points between sensory neurons and motor neurons. They do not directly activate muscles either.

Step 4: Learn about motor neurons. Motor neurons are responsible for transmitting signals from the CNS to effectors, such as muscles or glands, in the peripheral nervous system. They directly activate muscles to produce movement.

Step 5: Conclude that motor neurons are the type of neuron responsible for activating a muscle in the peripheral nervous system, as they carry signals from the CNS to the muscles.
