AP PSYCHOLOGY

Detailed explanation-1: -As you are reading this question, the cells in your eyes are firing in response to the light coming from this paper. Which type of neuron is carrying this message to the brain? myelin sheath.

Detailed explanation-2: -There are three classes of neurons: Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Motor neurons control voluntary muscle activity such as speaking and carry messages from nerve cells in the brain to the muscles. All the other neurons are called interneurons.

Detailed explanation-3: -Interneurons. As the name suggests, interneurons are the ones in between-they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.

Detailed explanation-4: -The dendrites are tree-like structures. Their job is to receive signals from other neurons and from special sensory cells that tell us about our surroundings.

Detailed explanation-5: -Correct answer: An action potential is a very brief shift or spike in a neuron’s electrical charge that sends a message down the axon. An action potential is the can be described as a neuron “firing.” Action potentials occur after the resting potential and before a refractory period.
