The Nervous System! Question n answers graded A+ 2023 passedCentral nervous system - correct answer Part of the nervous system that is made up of the brain and spinal cord. It interprets incoming messages and sends messages out to the peripheral nervous system. Peripheral nervous system - correct answer Part of the nervous system that consists of all of the nerves of the body. These nerves receive stimuli and send information to the central nervous system. They also receive directions from the central nervous system and control direct actions. Neurons - correct answer Nerve cells. They carry electrical messages from one area of the body to another area. Dendrite - correct answer The branched part of the neuron that receives incoming messages from other neurons. They send electrical messages TOWARD the cell body. Myelin - correct answer An insulating layer (made mainly of fat and protein) along the axon of a nerve cell. It speeds up the message along the axon. Letter E in the diagram. Cell body - correct answer The large part of a neuron, where the nucleus is located. It connects the dendrites and axon of the neuron to each other. Axon - correct answer The long part of a nerve cell, it conducts impulses away from the cell body. Stimulus - correct answer A change in the environment that can be perceived by sensory receptors (sound, light, pain, temperature, etc...) that elicits a response synapse - correct answer A gap or space between two neurons. This is where the electrical signal from the axon is converted into a chemical message and passed across the gap to the dendrites of the next neuron.
