Anatomy The spinal cord is part of the central nervous system (CNS). It is situated inside the vertebral canal of the vertebral column. During development, there’s a disproportion between spinal cord growth and vertebral column growth. The spinal cord finishes growing at the age of 4, while...
Spinal Tracts Functions In general, the major functions of the spinal cord include: Conduction of nerve signals: Afferent / sensory input from the periphery → brain Efferent / motor /visceral signals from the brain → periphery Modulates reflexes Overview of spinal tracts Ascending tracts: Carr...
The purpose of this chapter is to provide an overview of essential spine anatomy to assist the reader in understanding various structures of the central nervous system (CNS) and their relevance to intrathecal drug therapy. Structures such as the spine, spinal cord, meninges, cerebrospinal fluid, ...

The spinal cord contains many myelinated neurons in its outer region of white matter. These neurons carry information either toward the brain in ascending tracts or from the brain to the body in descending tracts. Ascending tracts are made of afferent or sensory neurons that provide sensory infor...

The spinal cord is part of the central nervous system and coordinates motor, sensory, and reflex signals. Anatomically, the spinal cord is located within the spinal canal and extends from the botto...
Relevant spinal cord anatomy The spinal cord is a soft, pliable mass of nerve fibers and cells supported by glial tissue. It is elliptically shaped with enlargements in the cervical and lumbar segments and extends from the base of the brain through the central canal to the level of the L1...

the brain are in the middle part of the spinal cord. These tracts are called the “spinothalamic”. Other tracts carry sensation of position and light touch. These nerve impulses are carried along the back part of the spinal cord in what are called “dorsal columns” of the spinal cord. ...
