They are named for the area of the vertebral column from which they come. Fissures and sulci extend along most of the external surface of the spinal cord. The posterior root of the nerve carries sensory information into the posterior horn, often synapsing there. Because the spinal nerves contain both sensory and motor fibers, they are considered a mixed nerve, as opposed to either a sensory or motor nerve. The spinal cord, which consists of the major nerve tract of vertebrates, runs down from the bottom of the brain through the passageway of the spinal column. Cross-sections of the Spinal Cord. Translations available in English, French, Portuguese, Italian, Polish, Russian, German, Chinese, Korean, Japanese and Spanish. Spinal Nerves . The anatomy of the grey matter of the spinal cord is summarized on a diagram with the various grey matter nuclei (note that this representation is virtual because some nuclei are only present at some levels between them but are displayed on a single cross-sectional diagram). 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. Gray Commissure . In transverse section, the spinal cord is incompletely divided into right and left halves by an anterior (ventral) median fissure and a posterior (dorsal) median sulcus and septum . For clearer demonstration of the spinal cord cross section, watch the video below: The white matter has the nerve fibers that run up and down the length of the cord, they are called axons. The main difference is that the ratio of gray matter to white matter varies among segments of the spinal cord. Another function of the spinal cord is maintaining muscle tone and producing reflexes. The outermost layer of meninges, the dura mater, forms the tough outer shell of dense fibrous connective tissue that protects the spinal cord. Unmyelinated Axons EM Schwann cells and oligodendrocytes can also associate with axons but not wrap them in myelin sheaths. spinal nerve. This is an online quiz called Label cross-section of spinal cord. A small, circular tube-like cavity known as the central canal sits in the center of the gray matter.

This is because the lateral horns contain the neurons of the sympathetic nervous system, which leave the cord only in these segments. Viewed in a cross-section, it has a roughly oblong shape with white matter on its exterior and a butterfly-shaped region of gray matter on its interior. It consists of horns (four projections) and forms the core mainly containing neurons and cells of the CNS. Then, two axial sections of the spinal cord and adjacent structures allow the organisation of a spinal nerve to be displayed with its various branches (sensitive posterior root, anterior motor root, meningeal branch, muscular branches, intercostal nerves) and represent the different spaces and meninges covering the spinal cord (epidural space, subdural space, subarachnoid space, pia mater, spinal dura, arachnoid spinal). The cell bodies of autonomic motor neurons are found in the lateral horns and extend their axons through the anterior horns, while the cell bodies and axons of somatic motor neurons are only found in the anterior horns. All these original anatomical diagrams were created by Micheau, Antoine - MD. This leads to an area of increased spinal cord thickness in the lumbosacral regions of the spinal cord (corresponding to a region associated with the inferior thoracic vertebrae) called the lumbar enlargement. The arterial supply of the spinal cord is shown on three different illustrations: an anterolateral view of the thoracic spine showing the emergence of the anterior spinal artery from the root and intercostal arteries), an axial section showing the branches of costal arteries destined for spinal cord and muscle and finally an overview of the Quiz Type.

But because most of this information has to either exit the spinal cord to send signals to peripheral tissues (efferent transmission), or information from peripheral tissues needs to be carried into the spinal cord (afferent transmission), there must be appropriate structures for these types of transmission to occur. This is an online quiz called Spinal Cord (cross section ) There is a printable worksheet available for download here so you can take the quiz with pen and paper. View and draw a small area of the white matter. This online quiz is called Spinal Cord Labeling. A&P lab exam 3. Look no further than these interactive, exam-style anatomy quizzes. For example, the thoracic segments have relatively small anterior horns, as there is little skeletal muscle to innervate in the thorax and abdomen, while the cervical and thoracolumbar regions have large anterior horns, used to innervate the skeletal muscles of the arms and legs, respectively. Sensory neurons enter the spinal cord through the posterior spinal root, and their axons make up the posterior horn. The spinal cord acts as a conduit for information traveling up and down its length. #1. posterior root ganglion. This quiz is filed in the following categories. This is most obvious when considering those spinal nerves arising in the lower lumbar and sacral regions. You may note from its name that it is an ascending tract, so the information that it carries is sensory. 24/75 EXAMPLES. These columns are sometimes called funiculi (or funiculus when singular) and are made up of axons that are traveling up (ascending) or down (descending) the spinal cord. RachaelHG1. All Rights Reserved. Every bundle of axons is a tract and it transmits specific information. Join 2023 Edraw Special Sales. The lateral horn is not found at all levels of the spinal cord, but is limited to thoracic and lumber segments of the cord. This neuron projects its axon via a descending white matter tract to a point in the spinal cord where it synapses in the ventral horn with a lower motor neuron. Learn anatomy faster and Start Now < by . Value. It is surrounded by the neuron axons or the white matter. Anterior rootlets carry motor information out of the spinal cord (i.e. The dorsal and ventral horns have the neurons that direct the skeletal muscles; the lateral horn has the cells that work the smooth muscle and supply cardiac. Click to reveal The spinal nerves come out from the spaces between the bony arches in pairs. 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.
