5X Spinal Cord Human Nerve Anatomical Model Medical Vertebral Partial Magnification Cervical Column for Patient Science Education Branches Ganglion Blood Vessels Teaching

Spinal Nerve Magnification 5x: The spinal nerves are made of high-quality PVC and magnified 5x. The model clearly displays all the anatomical structures of the spinal nerves Size: 43X20X16CM.Comes with display base; Highly detailed anatomical model. Suitable for school teaching tools, learning displays and collectibles, but also an important addition to laboratory supplies Morphology of spinal nerves: Each pair of spinal nerves are connected to the spinal cord through the ventral and dorsal roots. The anterior and posterior roots are composed of root filaments composed of many nerve fiber bundles Spinal nerve model: A total of 31 pairs of spinal nerves connected to the spinal cord are distributed in the muscles of the trunk, ventral and extremities, responsible for the feeling and movement below the neck Spinal Nerve Morphology: Each pair of spinal nerves connects to the spinal cord via ventral and dorsal roots. Both the anterior and dorsal roots are composed of rootlets made up of numerous nerve fiber bundles. The ventral root is motor, while the dorsal root is sensory. The dorsal root is slightly thicker than the ventral root. The two roots merge into a spinal nerve trunk at the intervertebral foramen, where sensory and motor fibers intermingle
