The location of motor neurons in the anterior grey column of the spinal cord. The anterior grey column, (also known as the anterior horn of spinal cord and anterior cornu) is broad and of a rounded or quadrangular shape. Its posterior part is termed the base, and its anterior part the head, but these are not differentiated from each other by ...
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
The four main divisions of the spinal column, from top to bottom: cervical, thoracic, lumbar, and sacral. The lateral grey column (lateral column, lateral cornu, lateral horn of spinal cord, intermediolateral column) is one of the three grey columns of the spinal cord (which give the shape of a butterfly); the others being the anterior and posterior grey columns.
Lateral grey column: VII and X Lamina VII: intermediomedial nucleus, intermediolateral nucleus, posterior thoracic nucleus in the thoracic and upper lumbar region [6] Lamina X: an area of grey matter – the grey commissure surrounding the central canal. This region also serves to connect the anterior and posterior grey columns. [3]
Posterior horn of lateral ventricle in the brain, which passes forward, laterally and slightly downward, from the corpus callosum into the occipital lobe; Posterior horn of spinal cord, the dorsal (towards the back) grey matter section of the spinal cord that receives several types of sensory information from the body including light touch ...
This is in contrast with the dorsal spinocerebellar tract (C8 - L2/L3), which only has 1 unilateral axon that has its cell body in Clarke's column (only at the level of C8 - L2/L3). Originates from ventral horn at lumbosacral spinal levels. Axons first cross midline in the spinal cord and run in the ventral border of the lateral funiculi. These ...
The axons of second-order neurons ultimately synapse on neurons in the ventral posterior lateral nucleus (VPL) of the thalamus after coursing in the spinal lemniscus. After this, the 3rd order neuron fibers traverse the internal capsule and the corona radiata, ultimately synapsing in the post central gyrus (somatosensory cortex). The location ...
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
