what happens when the dorsal root of a spinal nerve is cut
Dorsal root of spinal nerve The medial division of the dorsal root contains myelinated fibres of larger diameter. These transmit information of discriminative touch, pressure, vibration, and conscious proprioception originating from spinal levels C2 through S5. These fibers are pushed in towards the posterior median sulcus to form the gracile fasciculus and the cuneate fasciculus of the posterior column–medial lemniscus pathway. If the dorsal root of a spinal nerve were severed it would lead to numbness in certain areas of the body.
T-bone steak To cut a T-bone from butchered cattle, a lumbar vertebra is sawn in half through the vertebral column. The downward prong of the 'T' is a transverse process of the vertebra, and the flesh surrounding it is the spinal muscles. The small semicircle at the top of the 'T' is half of the vertebral foramen.
