In the cortex of the brain, gray matter makes up the cortical (outer) regions, while the white matter tracts tend to make up the majority of the deep tissues of the brain, although there are exceptions to the latter, such as the deep basal and thalamic nuclei that are composed of gray matter. This work is used to drive the refrigerator.

Anterior rootlets carry motor information out of the spinal cord (i.e. This figure shows other important features of the spinal cord, many of them related to the spinal cords function of relaying information. Note! The columns can be further divided into tracts (sometimes called fasciculi), which is a way of functionally grouping the neurons based on similar origin, destination and function. 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 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. Label a cross section of the spinal cord + Learn Test Match Created by bluesas9 Terms in this set (7) intermediate neurone . spinal nerve. IMAIOS is a company which aims to assist and train human and animal practitioners. Next, the user will find anatomical sections of the spinal cord at different levels: cervical spinal cord (C2, C5), thoracic spinal cord (T10), lumbar spinal cord (L3) and sacral spinal cord (S3).

This table lists the major spinal tracts, indicates if they decussate, and provides a brief description of the types of information that they carry. At the lower levels of the spinal cord there is a greater ratio of grey matter to white matter. The ventral roots look like axon streaks against the white matter. by korimroberts19. Lab 28- Spinal Cord and Meninges. The Schwann cell wraps around the axon to envelop it in a myelin sheath that functions as an electrical insulator. 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. Examine the cross section of the lumbar spinal cord in slide 065-2. The vertebral column, or spine, is a group of twenty-six stacked vertebrae extending from the skull to the pelvis. This area is made up of all the nerve fibers that direct the reflex actions and convey the impulses that go back and forth to the brain. The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white matter. 22 terms. The following table lists the four main plexuses, the spinal nerves that contribute to each, and some of the main nerves that arise from them. 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. Much of our motor control is contralateral. 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. 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). Sensory neurons enter the spinal cord through the posterior spinal root, and their axons make up the posterior horn. The cell body of the lower motor neuron is in the gray matter of the spinal cord, and it projects its axon out one of the anterior rootlets and through the anterior root. Play Now.

A cross-section through the spinal cord is illustrated schematically in Figure 2.6 and 3.4. 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. In the image above, you can see how the central gray matter is somewhat butterfly shaped, with each side of the butterfly containing a posterior (dorsal) horn and an anterior (ventral) horn. This is because motor control is typically a two neuron pathway. A small, circular tube-like cavity known as the central canal . Previous question Next question.

The structure of the spinal cord aids it in carrying out these relaying and integrative functions. Rootlets . Recall that the central nervous system tissues can generally be divided into white matter and gray matter. Labeling a diagram requires applying knowledge of a concept. Students, teachers and rockstars alike all come here to create and learn. At the back are two dorsal horns and away from the back are two ventral horns. Printable Worksheet. Even though the cell bodies are found in the lateral horns, their axons leave via the anterior nerve roots, just like those that control skeletal muscle. Finally, the size of the anterior and posterior horns varies, depending on the amount of tissue they are innervating. they contain efferent fibers) while the posterior rootlets carry sensory information into the spinal cord (i.e. Lateral Horn . 240 plays. The innermost layer of meninges, the pia mater, covers the surface of the spinal cord and contains many blood vessels to support the spinal cords tissues.

This is a printable worksheet made from a PurposeGames Quiz. 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. This is because the lateral horns contain the neurons of the sympathetic nervous system, which leave the cord only in these segments. If you are looking for the online quiz that this printable worksheet is based on, visit Spinal Cord Cross Section Labeling. ninalahoti. The 10 spinal laminae of the spinal cord are shown on a second diagram about the grey matter of the spinal cord.
