2023年8月16日 · The fasciculus gracilis is found throughout the spinal cord and begins at the caudal end of the spinal cord. It comprises long ascending fibers from different spinal nerves which enter the spinal cord through the ipsilateral dorsal spinal root, including sacral, lumbar and lower six thoracic nerves.

2023年7月26日 · The gracilis fasciculus, also known as the “column of Goll”, carries tactile and proprioceptive information from the lower half of the body (T7 to the first coccygeal nerve). It lies medially to fasciculus cuneatus within the posterior half of the posterior spinal cord.

2023年7月24日 · The gracile nucleus situates in the midline dorsal medulla at the junction of the brainstem and the spinal cord. The gracile fasciculus carries sensory input from vertebral level T6 and below and ascends into the gracile nucleus to form the gracile tubercle.

The gracile fasciculus refers to a slender bundle of sensory fibers that transmit information from the mid-thoracic level and below, including the lower limbs. AI generated definition based on: Clinical Neuroscience, 2014

2022年3月21日 · The gracile fasciculus, also known as the fasciculus gracilis (plural: fasciculi graciles) or column of Goll, represents the medial portion of the dorsal columns and carries input from below and including T7 1.

2023年11月16日 · Most of the long ascending fibers go on to form the fasciculus gracilis (throughout the length of the spinal cord) and the fasciculus cuneatus (at and above the level of the sixth thoracic vertebra).

2023年5月1日 · The axonal processes leave the dorsal horn gray matter and enter the dorsal funiculus to constitute either the fasciculus gracilis or the fasciculus cuneatus. Fasciculus gracilis carries sensory information from the lower limbs and synapses with the nucleus gracilis in the caudal medulla.

The gracile fasciculus is the tract or bundle that consists of first-order neurons of the dorsal column-medial lemniscal pathway, responsible for transmitting sensations of vibration, conscious proprioception, and two-point discrimination from the lower extremities.

2024年6月7日 · The gracile fasciculus (fasciculus gracilis or tract of Goll) is a bundle of axon fibers in the posterior column-medial lemniscus pathway of the spinal cord and carries information from the middle thoracic and lower limbs of the body.

The fasciculus gracilis synapses in the nucleus gracilis in the medulla, where secondary fibers eventually cross the midline forming the medial lemniscus which terminates in the thalamus.
