Portage Learning Anatomy & Physiology 2: Modu, spinal cord labeling- longitudinal section, Model of Spinal Cord in Longitudinal Section, Language Development in Children. carries somatic sensory information to the dorsal root and carries somatic motor information that supplies muscles and skin sensation to the back, send electrical signals between your brain, spinal cord and the rest of your body; these electrical nerve signals help you feel sensations (sensory nerve) and move your body (motor nerves), brings sensory information (both visceral and somatic) into the dorsal horn to be processed by either the lateral or ventral horn, contains outgoing, efferent (go away from) fibers that carry information destined to control motor or glandular function, a nodule on a dorsal root that contains cell bodies of afferent spinal nerve neurons, fundamental part of the sympathetic nervous system, and part of the autonomic nervous system; allows nerve fibres to travel to spinal nerves that are superior and inferior from their origin, convey autonomic signals, specifically for the sympathetic nervous system, processes sensory information, both visceral and somatic; intermediary processing center, processes somatic motor information; sends impulses to the skeletal muscles, carries cerebrospinal fluid (CSF), which it receives from the ventricular system of the brain and helps to transport nutrients to the spinal cord as well as protect it by cushioning the impact of a force when the spine is affected, processes visceral motor information and goes out the ventral root; central component of the sympathetic division of the autonomic nervous system, a groove along the anterior midline of the spinal cord that incompletely divides it into symmetrical halves, white matter of the spinal cord between the posterior horn on one side and the axons from the anterior horn on the same side; composed of many different groups of axons, of both ascending and descending tracts, carrying motor commands to and from the brain. 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. from receptor . Language en. You may be surprised to find out that the spinal cord in an adult comes in at about 17 1/4 inches long, is about as wide as your thumb, and is just as thin as a straw that you drink from at the base. Sensory and motor fibers enter and exit the cord via rootlets that arise from both the posterior and anterior aspects of the cord. Motor neurons exit the spinal cord through the anterior roots of the spinal nerves, so they are found in the anterior and lateral 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. 4. 208.113.148.196 Each segment of the cord contains matched posterior, lateral and anterior columns. 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.

Each horn has different functions. 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. Recall during development, newly formed neurons proliferate adjacent to the canal to form a mantle layer, which becomes the gray matter in the central region of the mature spinal cord. 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. 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). Fibers travel rostrally in the dorsal columns to synapse in the nucleus gracilis and nucleus cuneatus in the . Another function of the spinal cord is maintaining muscle tone and producing reflexes. 9p Image Quiz. These tracts are often named for the structures that they connect. The first image shows the different segments of the spinal cord (cervical, thoracic, lumbar, sacral and coccygeal segments), the emergence of spinal nerves (cervical, thoracic, lumbar and sacral nerves and coccyx at the level of the cauda equina and filum terminale) and the sectional aspect of the spinal cord with changes in diameter at the cervical and lumbosacral bulges. haley_brook_russell. The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white matter. A cross-section through the spinal cord is illustrated schematically in Figure 2.6 and 3.4. different parts of the spinal cord and between the cord and the brain. 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. Anterior Median Fissure .
