Medulla Spinalis

Medulla spinalis is commonly known as the spinal cord with a tubular structured long and thin bone made up with nervous tissues. It starts from the medulla oblongata (a part of the brain) and extends up to the vertebral column. The medulla spinalis surrounds the central canal, which is filled up with a fluid called cerebrospinal fluid. The central nervous system (CNS) comprises both the spinal cord and the brain. It acts as a bridge that connects the brain and the peripheral nervous system. The medulla spinalis is about 18 inches (45cm) and 17 inches (43cm) long in men and women respectively. It is overall divided into three regions - cervical, thoracic, and lumbar. It is secured by a layer of three thick layers of membranes or tissues known as meninges. Medulla spinalis’ major function is to transfer the nerve signal to the cortex of the body. It also acts as a junction for coordinating different types of reflexes. It is a kind of medium that is responsible for the communication between the brain and the body. An injury in the medulla spinalis can arise due to trauma, resulting in the shattering or puncture of the spinal cord. An injury in the medulla spinalis stops receiving all the signals from the brain
