Second, the vertebra protects the delicate tissues of the spinal cord by surrounding it with hard bone tissue. Download and print this quiz as a worksheet. In spinal nerves T1-L2, the anterior ramus gives rise to a communicating ramus that communicates with the sympathetic ganglia in the region. Because the spinal nerve roots dont always originate at the level of the vertebrae that they pass through, the segments of the spinal cord are named for the spinal nerve to which they give rise. 240 plays. A cross-section through the spinal cord is illustrated schematically in Figure 2.6 and 3.4. The 10 spinal laminae of the spinal cord are shown on a second diagram about the grey matter of the spinal cord. The anterior horn contains the cell bodies of somatic motor neurons, and it sends its axons out the anterior root of the spinal nerve to the muscle cells it innervates. Even though the cell bodies are found in the lateral horns, their axons leave via the anterior nerve roots, just like those that control skeletal muscle. The following diagram shows the spinal cord of the human body. The anterior root does not contain a ganglion. Descending nerve signals from the brain pass through the white matter to activate the muscles, glands, and organs of the body, while ascending nerve signals carry sensory information from the tissues of the body to the brain.
