    How long is the spinal cord?
    The spinal cord is approximately 45 cm in length and extends from C1 to the level of the L1 vertebra. 1 It is cylindrical in shape but tapers caudally and demonstrates 2 areas of focal enlargement in the cervical and lumbar region.

    What is a symmetrical spinal cord?
    The spinal cord is a long cylindrical extension of the central nervous system within the vertebral column's cavity. It is approximately 42.3 cm in length in males and 38.9 cm in females. Even though the spinal cord is almost symmetrical, it is enlarged in a fusiform shape in two regions in the form of cervical and lumbosacral enlargements.

    How is the spinal cord arranged?
    blood vessels. The white matter of the spinal cord is arranged in columns/funiculi; anterior, posterior and lateral. The nerve fibers are arranged as bundles, running vertically through the cord. These tracts are formed by sensory nerve fibers ascending to the brain, motor nerve fibers descending from the brain and fibers of connector neurons.

    How does the spinal cord work?
    The spinal cord is the conduit between the brain and the rest of the body, sending motor commands from the motor cortex to the muscles and sensory information from the afferent fibers to the sensory cortex. In certain instances, the spinal cord can act without signals from the brain, as it can independently coordinate reflexes using reflex arcs.

    What are the 4 parts of the spinal cord?
    According to its rostrocaudal location the spinal cord can be divided into four parts: cervical, thoracic, lumbar and sacral, two of these are marked by an upper (cervical) and a lower (lumbar) enlargement.

    What are the 5 segments of the spinal cord?
    Like the vertebral column, the spinal cord is divided into segments: cervical, thoracic, lumbar, sacral, and coccygeal. Each segment of the spinal cord provides several pairs of spinal nerves, which exit from vertebral canal through the intervertebral foramina.
