The integration of motor and sensory information during walking involves communication between cortical, subcortical, and spinal circuits. Step-like motor patterns of the lower extremities can be induced through activation of the spinal circuitry alone; [16] however, supraspinal input is necessary for functional bipedal walking in humans.
It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra. The dura is pierced with a needle during a lumbar puncture (spinal tap).
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
The spinomesencephalic pathway, spinomesencephalic tract or spino-quadrigeminal system of Mott, includes a number of ascending tracts in the spinal cord, including the spinotectal tract. [1] [2] [3] The spinomesencephalic tract is one of the ascending tracts in the anterolateral system of the spinal cord that projects to various parts of the ...
The axons enter the spinal cord from the dorsal root ganglia and terminate on unknown second-order neurons in the posterior grey column. [2] The axons from the second-order neurons cross the midline and ascend as the spino-olivary tract in the white matter at the junction of the anterior and lateral columns. [2]
The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [ 3 ] [ 4 ] All of the ventricular system and the central canal of the spinal cord are lined with ependyma , a specialised form of epithelium connected by tight junctions that make up the blood ...

The rostro-caudal axis of the human central nervous system (magenta in the diagram) makes a near 90° bend at the level of the midbrain and continues through the brain-stem and spinal cord. In human anatomy, the occipital lobes and the back of the head are posterior but not caudal to the frontal lobes and the face.
