The action you just performed triggered the security solution. Each of the horns is contiguous with the posterior and anterior spinal nerve roots, respectively. The ventral roots look like axon streaks against the white matter. In the spinal cord cross-section labeled diagram, we have shown Dorsal horn, Visceral sensory nuclei, Somatic sensory nuclei, afferent sensory information, efferent signals to muscles and glands via the ventral root, somatic motor nuclei, autonomic efferent nuclei, ventral horn, ventral root, lateral horn, and dorsal root ganglion. View and draw a small area of the white matter. Praxis, David N. Shier, Jackie L.

All Rights Reserved. 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. 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. #1. posterior root ganglion. ninalahoti. This work is used to drive the refrigerator. 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. Played. 22 terms.

The spinal nerves come out from the spaces between the bony arches in pairs. The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white matter. Cerebrospinal fluid flows around the pia mater in the hollow subarachnoid space beneath the second layer of meninges, the arachnoid mater. sammiesadler1 Plus. 6p Image Quiz. Distal to the posterior root ganglion, the fibers of the anterior and posterior root merge together and pass through the dura to become the spinal nerve. spinal nerve . It should be noted here that when needed, provide labels and, if applicable, accompanied explanation for each part of the diagram right inside the diagram. The spinal cord is made up of 31 segments. This is a printable worksheet made from a PurposeGames Quiz. It is the 31 pairs of spinal nerves and their related structures that provide the pathways for this interaction. Much of our motor control is contralateral.

Spinal Cord Cross Section Labeling Printable Worksheet Download and print this quiz as a worksheet. 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). How do you write a single quote as part of a string in SQL? These nerves contain fibers from several spinal nerves. Sensory neurons enter the spinal cord through the posterior spinal root, and their axons make up the posterior horn. The gray matter of the dorsal horns is thinner than the ventral horns.The dorsal roots can be cut in the cross section and come out from the horn area. For example, specialized nerve endings often act as sensors (receptors), information is carried along nerves and/or tracts of the spinal cord, integration occurs within the CNS, and spinal cord tracts and nerves carry the responding information back out to the effectors.

Each segment gives rise to a pair of spinal nerves. All these original anatomical diagrams were created by Micheau, Antoine - MD. For example, your right arm is mainly controlled by the motor area in your left brain. 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.
