Spinal nerves exiting the cord from the level of L4 to S4?
Lumbar plexus
What is formed by the spinal nerves exiting the cord from the level of L4 to S4?
Spinal nerves exiting the spinal canal between L4 and S4 collectively make up the sacral plexus.
What vertebra is least likely to cause a spinal cord injury if fracture?
L4
What do the spine levels L1 - L4 control?
Flexion of the thighs
What level of the spinal cord is damaged to cause urinary incontinence?
Parasympathetic nerves from the S2, S3 and S4 levels of your spinal cord cause the upper part of your bladder to contract and your bladder neck to relax, assisting in the process of micturition (urination). If these are damaged you will have bladder control problems.
What does diffuse disc bulge at L4-L5 causing mild narrowing of bilateral foramina indicative of?
What the radiology report indicates is that you've got a herniated disk at the L4/5 vertebrae, which is pressing forward into the spinal cord passageway. The foramen is the narrow passage in the vertebrae where the spinal cord runs through.
Sciatica reflects neuritis in a nerve from the?
Nerve root outlet of the spinal cord, most often between L4-L5 or L5-S1.
What is marginal osteophytes at L4 and L5 with reduced disc space?
MR imagemorphology is in favour of early marginal osteophytes at few levels. mildbroad disc bulge at l4-l5 causing minimal thecal sac indentation
What does L4-5 Annular bulge touching thecal sac resulting in moderate central stenosis with bilateral centrally located L5 neural abutment mean?
There's a bulge pushing through the ring holding the vertebral disk between L4 and L5. The bulge is narrowing the opening for the spinal cord somewhat, and is also touching both sides of the nerves coming off the spinal cord at L5.
Why does your penis float to the top of the water?
No - take a bath and see for yourself. yes- took a bath with boyfriend and there was definently floatation!
What does encroachment of the ventral subarachnoid space in the L4-L5 level mean?
Encroachment: Taking up space to which it's not entitled.ventral: belly sidesubarachnoid space: the area just under the membranes surrounding the spineL4-L5: the space between the fourth and fifth lumbar vertebrae.So, to sum up, something (probably a herniated disk?) is taking up space on the belly side of the spinal cord between L4 and L5. It's not pressing the cord, but it is crowding the space between the spinal cord and the surrounding membrane.
What is disc hydration loss?
* Loss of lumber lordosis* Loss of normal disc hydration seen at multiple levels * Disc bulge seen at L2 -3 L3-4 L4-5 and L5-s1 levels indenting anterior thecal sac with impingement of the corresponding exit nerve roots at l3-4 l4-5 and l50s1 levels* No spinal canal stenosis seen* Normal vertebral bodises
