All forms involve the pulling of the spinal cord at the base of the spinal canal, literally a tethered cord. [1] The spinal cord normally hangs loose in the canal, free to move up and down with growth, and with bending and stretching. A tethered cord, however, is held taut at the end or at some point in the spinal canal.
"Ventral" in the central nervous system also refers to the rostro-caudal axis, which changes within the head. These three axes of the human brain match the three planes within which they lie, even though the terms for the planes have not been changed from the terms for the bodily planes. The most commonly used reference planes are:
The root of a term often refers to an organ or tissue. For example, the Latin name musculus biceps brachii can be broken down: musculus meaning muscle, biceps meaning "two-headed", and brachii referring to the arm (brachial region). The first term identifies the structure, the second indicates the type or instance of the structure, and the ...
In forming or understanding a word root, one needs a basic comprehension of the terms and the source language.The study of the origin of words is called etymology.For example, if a word was to be formed to indicate a condition of kidneys, there are two primary roots – one from Greek (νεφρός nephr(os)) and one from Latin (ren(es)).

The filum terminale is situated centrally [2] amid the spinal nerve roots of the cauda equina [3] [2] (but is not itself a part of the cauda equina [2]).. The inferior-most spinal nerve, the coccygeal nerve, leaves the spinal cord at the level of the conus medullaris via respective vertebrae through their intervertebral foramina, superior to the filum terminale.
The injured spinal cord is an “altered” spinal cord. After a SCI, supraspinal and spinal sources of control of movement differ substantially from that which existed prior to the injury, [20] thus resulting in an altered spinal cord. The automaticity of posture and locomotion emerge from the interactions between peripheral nervous system ...
