Neuroscience questions and 100% correct answers

Neurons - correct answer •Our "information system" is made up from billions of neurons. -Neuron- cells in the nervous system that communicate with one another to perform information-processing tasks. •There are many different types of neurons, but all are built rather similarly. Parts of the Neuron - correct answer •Each neuron consists of a cell body and its branching fibers (dendrites). •Dendrites- the branching extensions of a neuron that receive information from other neurons and relay it to the cell body. •Information is passed from the dendrites along the axon. •Axon- the extension of a neuron that transmits information to other neurons, muscles, or glands. •Axons can be very long and are covered in a myelin sheath. •Myelin - insulating layer of fatty tissue on an axon to help speed the impulses. Composed of glial cells. The Synapse - correct answer Major Types of Neurons - correct answer Sensory Neurons - receive information from the external world and convey this information to the brain via the spinal cord. Motor Neurons - carry signals from the spinal cord to the muscles to produce movement.
