Effacement upon the anterior thecal surface refers to the thinning or reduction of the thecal sac that surrounds the spinal cord and nerves, typically due to pressure from a herniated disc or other spinal pathology. This condition can lead to compression of the neural structures, potentially causing pain, numbness, or weakness in the affected areas. It is often assessed through imaging studies like MRI to determine the extent of the effacement and guide treatment options.
The thecal sac is the covering for the spinal cord. This can be seen on an MRI. Impingement means that something is pressing on it.
Ventral means in front. Thecal sac means the sac that contain the spinal cord and cerebro spinal fluid. Effacement of the ventral thecal sac means pressure is upon the front of the sac (producing a flattening effect) most likely from a disc protrusion. Foramen means hole (where the nerve comes out of from the spinal cord). Stenosis means narrowing (usually from bony degeneration or disc herniation/protrusion/or bulge). Left foraminal stenosis means narrowing of the passageway where the nerve comes through.
A paracentral posterior disk protrusion at the T12-L1 level refers to a bulging of the intervertebral disk that is located towards the center and posteriorly, which can encroach upon the spinal canal. This type of protrusion can exert pressure on the anterior aspect of the thecal sac, which houses the spinal cord and nerve roots, potentially leading to symptoms such as pain, numbness, or weakness in the lower extremities. The condition may require monitoring or treatment depending on the severity of symptoms and the degree of nerve compression.
wide herniation that is larger at center mid-line pushing the disc out and beginning to but not yet touch or push on the thecal sac.
They are produced in the anterior pituitary and act mostly notably on the uterus
C5, C6, and C7 disc prolapse refers to the herniation of intervertebral discs in the cervical spine, specifically between the C5-C6 and C6-C7 vertebrae. This condition can lead to nerve compression, where nearby nerves are pinched, causing pain, weakness, or numbness in the arms. The compression of the thecal sac indicates that the protective covering of the spinal cord and nerves is being pressed upon, which may lead to further neurological issues. The inability to see the exit of the thecal sac suggests that imaging may not clearly show where the nerves exit the spinal canal, possibly complicating diagnosis or treatment.
Epidermal means pertaining to upon the surface of the skin.
Partial encroachment upon the anterior subarachnoid narrowing indicates that there is some degree of obstruction or compression affecting the anterior portion of the subarachnoid space, which is the area surrounding the brain and spinal cord containing cerebrospinal fluid. This condition can potentially impact the flow of cerebrospinal fluid and may lead to neurological symptoms. The term suggests that while there is a restriction, it is not complete, allowing for some degree of fluid movement. Further evaluation may be needed to determine the cause and potential implications of this finding.
The Color of stars depends upon their surface temperature.
No. Only if you get sat upon.
The surface is the ground upon which the medium is applied. If you are painting with oils, you are likely using stretched canvas or masonite board as a surface. If you are drawing in pastels, your surface may be Canson paper.
Yes, the force that one surface exerts upon another surface is called contact force. This force occurs when two surfaces are in direct contact with each other and can be either a normal force, frictional force, or tension force depending on the nature of the interaction between the surfaces.
