L2
In adults, the spinal cord terminates at approximately the level of L1. The nerve roots then descend through a fluid sac containing cerebrospinal fluid and are referred to as the cauda equina ("tail of a horse").
The hyoid bone is at the level/in line with the third cervical (C3) vertebra.
Lumbar plexus
The cerebral cortex can not over ride reflexes. Reflex are mediated at the level of the spinal cord.
L2
The spinal cord ends at the level of the first lumbar vertebra, which is just below the level of the ribs.
In adults, the spinal cord terminates at approximately the level of L1. The nerve roots then descend through a fluid sac containing cerebrospinal fluid and are referred to as the cauda equina ("tail of a horse").
Lumbar Vertebra 3
Spondylolyis is a condition where there is an injury (stress fracture or fracture) in the pars interarticularis of the posterior elements of the spine. Spondylolisthesis describes the anterior displacement of a vertebra or the vertebral column in relation to the vertebrae inferior to it. The forward translation of the vertebral body causes narrowing of the central spinal canal at the level of the slip.
Your legs shoudn't work anymore. Your legs shoudn't work anymore.
False. Spinal cord is not there at this level. There is a structure called as cauda equina. It is like the tail of the horse.
The diaphragm would still be innervated, but the intercostal muscles would not. The person would only be able to undertake quiet breathing
at the level of the first lumbar vertebra
cv 16
In an adult the lower end of the spinal cord usually ends at approximately the first lumbar vertebra, where it divides into many individual nerve roots (L1). That is the reason Lumbar Puncture usually perform at L3-L4 in order to prevent accidentally injure to the spinal cord. The point where the spinal cord ends is referred to as the "conus medullaris"
In the human the level of cricoid is the 6th cervical vertebra.
