Handout Master 2.3Fill-in-the-Blanks1.An extensive network of specialized cells that carry information to and from all parts of thebody is called the Nervous System.2.The basic cell that makes up the nervous system and which receives and sends messageswithin that system is called a Neurons.3.The long tube-like structure that carries the neural message to other cells on the neuron isthe Axon.4.On a neuron, the branch-like structures that receive messages from other neurons is theDendrites.5.The cell body of the neuron, responsible for maintaining the life of the cell and contains themitochondria is the Soma.6.The fatty substances produced by certain glial cells that coat the axons of neurons toinsulate, protect, and speed up the neural impulse is the Myelin.7.The bundles of axons in the body that travel together through the body are known as theNerves.8.The charged particles located inside and outside of the neuron are called Ions.9.The state of the neuron when not firing a neural impulse is known as the Resting potential.10. The Synaptic vesiclesare sack-like structures found inside the synaptic knob containingchemicals.11. Neurotransmittersare chemicals found in the synaptic vesicles which, when released, hasan effect on the next cell.
