Answer the following question given this paragraph: Gray Horns In cross-section, the gray matter of the spinal cord has the appearance of an ink-blot test, with the spread of the gray matter on one side replicated on the othera shape reminiscent of a bulbous capital "H. " As shown in Figure 13.14, the gray matter is subdivided into regions that are referred to as horns. The posterior horn is responsible for sensory processing. The anterior horn sends out motor signals to the skeletal muscles. The lateral horn, which is only found in the thoracic, upper lumbar, and sacral regions, is the central component of the sympathetic division of the autonomic nervous system. Some of the largest neurons of the spinal cord are the multipolar motor neurons in the anterior horn. The fibers that cause contraction of skeletal muscles are the axons of these neurons. The motor neuron that causes contraction of the big toe, for example, is located in the sacral spinal cord. The axon that has to reach all the way to the belly of that muscle may be a meter in length. The neuronal cell body that maintains that long fiber must be quite large, possibly several hundred micrometers in diameter, making it one of the largest cells in the body. Q: What type of matter in the spinal cord has the appearance of an ink-blot test and is subdivided into regions that are referred to as horns? A:
OPTIONS:
- bright matter
- wet matter
- dark matter
- gray matter
gray matter

Answer the following question given this paragraph: Figure 29.3 Graphs of blackbody radiation (from an ideal radiator) at three different radiator temperatures.
