It reduces inflammation in lung tissues after spinal injury [1], aids in spinal cord regeneration through the mTOR pathway and autophagy [2], protects against spinal cord hypoxic injury through Nrf-2 [3], and aids in spinal regeneration by reducing inflammation through the Notch signaling pathway [4]. The nerves exit the bony canal through passageways, called . Together, GDF-11 protects the injured spinal cord by suppressing pyroptosis and necroptosis via TFE3-mediated autophagy augmentation and is a potential agent for SCI therapy. Ventricles are spaces inside the brain filled with CSF. The spinal canal formed by the lumbar vertebrae protects these structures by providing a strong, bony casing. Bony Protection: Spinal cord is protected by vertebrae of vertebral column. miR-199a-5p or silencing of ECE1 also regulated the expressions of caspase-9, Bcl-2, p-JNK, p-ERK, and ECE1 in rat spinal cord injury after I/R. The spine is made of 33 bones called vertebrae. The vertebrae are separated by disks made of cartilage, which act as cushions, reducing the forces on the spine generated by movements such as walking and jumping.

Portions of the spine surround the spinal cord providing bony protection for the spinal cord just as the skull protects the brain with a bony shell. I hope it helps. Thanks 26. Between each pair of vertebrae, you have a spinal disk. Meninges have completely three layers Dura mater (which is closest to the bone), Arachnoid (which is loosely around the brain) and Pia mater (which is closely attached to the brain and spinal . The spinal cord is a major part of the central nervous system which comprises tubular nerve bundle while the vertebral column is a bony, segmented structure which supports head and thorax. Tetraplegia is a paralysis that results in total or partial loss of use of all four limbs and torso. It supports and protects the brain and the spinal cord. The dura mater is the outermost layer, and it forms a tough protective coating. It has nerve cells called neurons that are divided into white matter, which has a fatty white coating called myelin, and gray matter. Made up of individual vertebrae (bones), the spine protects the spinal cord.. What are the 3 layers of the meninges. Herein, what protects the spinal cord? Which bones support the back and the head?
