Detailed explanation-1: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.
Detailed explanation-2: -Axon: the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons, muscles, or glands.
Detailed explanation-3: -An extension or process called an axon carries impulses away from the cell body. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.
Detailed explanation-4: -The parts of neurons that send messages are the axons, and the parts of neurons that receive messages are the dendrites. 3. The space between the dendrites of one neuron and the axon of another neuron is called the synapse.
Detailed explanation-5: -Dendrites are short, branched hair-like extensions of a neuron.
