label spinal cord cross section

The white matter of the spinal cord is divided into the paired posterior (dorsal), lateral, and anterior (ventral) columns. Spinal Cord (cross section ) Quiz Information. Students, teachers and rockstars alike all come here to create and learn. The ascending tracts generally carry sensory information from the periphery to the brain, while the descending tracts carry motor signals to muscles and glands. This table lists the major spinal tracts, indicates if they decussate, and provides a brief description of the types of information that they carry. 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. An example of a spinal reflex is withdrawing the hand when it detects pain. Click on a category of cookies to activate or deactivate it. All but the first spinal nerve (C1) pass through the intervertebral foramen of the spinal cord, whereas spinal nerve C1 passes between the occipital bone and vertebrae C1. Each of these regions, or columns, contains thousands of axons traveling between the brain and the bodys tissues. Cookies allow us to analyze and store information such as the characteristics of your device as well as certain personal data (e.g., IP addresses, navigation, usage or geolocation data, unique identifiers). Give it a try! 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. 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. 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. Another function of the spinal cord is maintaining muscle tone and producing reflexes. 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. ninalahoti. Gray matter contains the cell bodies and dendrites and therefore is the site of synaptic transmission. They are named for the area of the vertebral column from which they come. Write the Lewis structure for each molecule.

It was created by member NothingNew22 and has 12 questions. Your IP: Each segment gives rise to a pair of spinal nerves. What is the role of the ventral root? In all there are 31 pairs of spinal nerves that carry information to and from the spinal cord and the periphery of the body. It consists of horns (four projections) and forms the core mainly containing neurons and cells of the CNS. The action you just performed triggered the security solution.
