Identify the pattern of white and gray matter in each region of the cord, noting which nuclei are found only in restricted parts of the cord. The spinal cord is a nervous system structure dedicated to relaying information from the periphery to the brain and back, as well as carrying out certain levels of integration, such as those found in many reflexes. This online quiz is called Spinal Cord Labeling. 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). Because the spinal cord terminates near vertebrae L1, and there is a lot of body tissue that needs to be innervated below this level, there are a significant number of nerves arising from the lower aspect 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. 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 should make sense, as there are less ascending and descending tracts of whiter matter as you move lower. Module 06 Lab Worksheet Dorsal root ganglia convey information from external or internal sites of the body such as actual or potential harm, temperature, or muscle length to the central nervous system. Spinal cord cross-section, detailed anatomy. Looking at a cross section of the spinal cord, you would see gray matter shaped like a butterfly surrounded by white matter. Create. Expert Answer. Anatomy of the Human Heart - Posterior View. At the lower levels of the spinal cord there is a greater ratio of grey matter to white matter. These nerves contain fibers from several spinal nerves. 24/75 EXAMPLES. Although each segment of the spinal cord has similar features, there are some differences along its length, as you may be able to determine from the image above. Motor neurons exit the spinal cord through the anterior roots of the spinal nerves, so they are found in the anterior and lateral horns. This is a printable worksheet made from a PurposeGames Quiz. The anterior columns and posterior columns are partially separated by the anterior median fissure and posterior median sulcus, respectively. 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 nerve bundle has a cushion of cerebrospinal fluid between it and the meninges. These unipolar peripheral neurons are considered first order neurons in the sensory pathway, while the neurons they synapse with in the posterior horn are considered the second order neurons of the sensory pathway. This way, the labels, and explanations will be together in an integrated format instead of a split-source format. Ganglia are only found where neuron cell bodies are outside the CNS. At low magnification, differentiate inner gray from outer white matter and identify dorsal and ventral horns of the gray matter. The ventral roots look like axon streaks against the white matter. The vertebral column, or spine, is a group of twenty-six stacked vertebrae extending from the skull to the pelvis. A diagram summarizes the composition of white matter cords of the spinal cord with the different tracts (fasciculus gracilis (Goll's), wedge-shaped beam (Burdach's), corticospinal tract, spinocerebellar tract). In all there are 31 pairs of spinal nerves that carry information to and from the spinal cord and the periphery of the body. By printing out this quiz and taking it with pen and paper creates for a good variation to only playing it online. This is because motor control is typically a two neuron pathway. The columns are further divided as axons traveling to the brain form clusters known as ascending tracts while axons leaving the brain form descending tracts. The spinal nerves come out from the spaces between the bony arches in pairs. In general, the posterior ramus communicates with structures posterior to the cord, while the anterior ramus communicates with structures anterior to the cord. Determine the ratio of the heat transferred from the 400F400 \mathrm{~F}400F reservoir to the heat transferred from the 20F-20 \mathrm{~F}20F reservoir, assuming all processes are reversible.

In an adult, the spinal cord itself terminates at a point called the medullary cone, at approximately the level of the first lumbar vertebrae (L1). . These tracts are often named for the structures that they connect. Several shallow furrows (known as sulci) and a deep furrow (known as the anterior median fissure) penetrate the white matter and divide it into several regions. A small, circular tube-like cavity known as the central canal sits in the center of the gray matter. Brainstem and Cranial Nerves 1. It is the axons of these second order neurons that make up the various ascending white matter tracts. This work is used to drive the refrigerator. Hit me! Gray matter contains the cell bodies and dendrites and therefore is the site of synaptic transmission. All these original anatomical diagrams were created by Micheau, Antoine - MD. 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).
