Some of the tracts cross over (decussate) either in the spinal cord or brainstem, and when this occurs, the relationship between the origin and destination is termed contralateral. 55. haley_brook_russell. The anterior root does not contain a ganglion. 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 lateral horn is not found at all levels of the spinal cord, but is limited to thoracic and lumber segments of the cord. The action you just performed triggered the security solution. It is surrounded by the neuron axons or the white matter. These are unipolar neurons, such that their dendrites extend out to the peripheral tissues, and their axons project into the dorsal horn of the spinal cord, where they synapse. It is the 31 pairs of spinal nerves and their related structures that provide the pathways for this interaction. The integration of sensory information produces spinal reflexes in the spinal cord to cause a motor response to stimuli faster than the distant brain could make the same response. Anatomy and Physiology questions and answers Label the cross-section of the spinal cord showing ascending (sensory) tracts (patiways) on one side (in red) and the descending (motot) tracts (pathways) on the other side (in green) by clicking and dragging the labets to the correct location. The sympathetic motor pathway involves two motor neurons, so this ganglion houses the second motor neurons cell body. The tracks that move upward are responsible for signals to the brain and the descending tracts send the signals from the brain to neurons throughout the body. The Schwann cell wraps around the axon to envelop it in a myelin sheath that functions as an electrical insulator. Cloud Types. the ventral section of white matter in the spinal cord between the ventral horns. 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.

The white matter of the spinal cord is divided into the paired posterior (dorsal), lateral, and anterior (ventral) columns. 4. The spinal cord acts as a conduit for information between the brain and the body below the neck. Starting between the base of the skull and the first cervical vertebrae, and continuing into the sacral region of the spinal column, a pair of spinal nerves extend from the spinal cord (although information is transmitted in both directions on sensory and motor neurons within these mixed nerves). Write the Lewis structure for each molecule. Interneurons that connect the sensory and motor neurons are found in the center of the gray matter between the horns. The outer zone contains many myelinated axons that run up and down the spinal cord. 22 terms. At the back are two dorsal horns and away from the back are two ventral horns. 164,876 times. Meninges and soft tissues surround the spinal cord, protecting its delicate nervous tissue and containing cerebrospinal fluid. In spinal nerves T1-L2, the anterior ramus gives rise to a communicating ramus that communicates with the sympathetic ganglia in the region. The ventral roots look like axon streaks against the white matter. If you are looking for the online quiz that this printable worksheet is based on, visit Spinal Cord Cross Section Labeling. The venous vasculature is shown on an anatomical section at the thoracic level (anterior and posterior spinal veins, basivertebral veins, vertebral venous plexus). Along the posterior root is a ganglion, where cell bodies of many of the sensory neurons are found. The columns are further divided into tracts that carry sensory information up the spinal cord (ascending tracts) and motor information down the spinal cord (descending tracts). In contrast to this general arrangement of the brain, the spinal cord is arranged with the white matter surrounding the central gray matter, indicating that the spinal tracts carry information up and down the cord along the outer aspects, while synaptic transmission tends to occur more centrally. Dorsal Horn . How do you write a single quote as part of a string in SQL? 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). The central canal is filled with cerebrospinal fluid, which circulates from the ventricles of the brain to the central canal and around the surface of the spinal cord. All rights reserved.
