Detailed explanation-1: -Vazquez is examining a cell from the nervous system of an animal. He notices that at one end of the cell body is a long, fibrous strand of tissue. He immediately recognizes this as an axon that is responsible for a. carrying signals away from the cell body.
Detailed explanation-2: -An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles. A protective covering called the myelin sheath, covers most neurons. Myelin insulates the axon and helps nerve signals travel faster and farther.
Detailed explanation-3: -Neurons are the basic building blocks of the nervous system. These specialized cells are the information-processing units of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in communicating information throughout the body.
Detailed explanation-4: -Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. Glia are also essential to nervous system function, but they work mostly by supporting the neurons.
Detailed explanation-5: -Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues.
