Answer to: Nerve fibers that carry impulses toward the central nervous system are called: A. efferent neurons. B. dendrites. C. afferent neurons...
Although cells are the building blocks on which the human body is structured, they themselves are also composed of smaller units. These units are organelles, functional units within the cytoplasm that have their own bilipid membrane. Breaking down the organelles, we see that they, like all livin...
1. Cells that myelinate axons in the central nervous system 2. Cells that help reinforce the blood-brain barrier. 3. Glial cells found in peripheral nerve ganglia. ___ leads to the autonomic ganglion. ___ is the neuron that conducts impulses toward the CNS from the body periphery. ...
1.Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves in vertebrates, consisting of a nucleated cell body with one or more dendrites and a single axon. 2.A similar impulse-conducting cell in invertebrates. In both senses also callednerve cell. ...
The most studied, and excitable, of the cells that conduct nerve impulses are known as neurons. A “typical” neuron is depicted in Fig. 18.14. By even a cursory glance, the extreme asymmetry of a neuron is obvious. The major structural features of a neuron include a single soma or cell...

A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells...
