What is T2 hyperintens?
T2 hyperintensity refers to an area in an MRI scan that appears brighter than surrounding tissues on a T2-weighted image. This can indicate various conditions such as inflammation, edema, or fluid accumulation in that particular area of the body. It is important for a healthcare professional to assess the clinical context to determine the significance of T2 hyperintensity.
What is annulus?
We all have cartilaginous discs that separate the spinal bones, or vertebraes, from each other. These discs allow for movement within the spine. Each disc has a fibrous outside, called the annulus fibrosus, and a liquid center, called the nucleus pulposus. Think of a disc as a jelly donut. The jelly is the nucleus and the donut is the annulus. If the fibers of the inner annulus tear, the jelly nucleus, which is tightly held in the center, follows the path of least resistance and pushes towards the wall of the annulus. When this happens, the wall of the annulus is warped and appears to bulge or protrude. This is known as a protruding annulus or ,in other words, a bulging disc. If the annulus continues to weaken and tear, the nucleus has potential to eject from the disc. The annulus will no longer be bulging, as the wall has opened and the jelly nucleus has squeezed out or herniated. This now constitutes a herniated disc.
Nueron cell bodies are found in clusters within the posterior root is called?
dorsal root ganglion
What does it mean the brain parenchyma shows periventricular T2 hyperintensity and a few scattered subcortical foci of increased T2 and flair signal intensity in the frontal lobes that are nonspecifi?
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
What is mild diffuse cerebral and cerebellum volume loss and T2 hyperintesnity within the periventricular white matter?
Mild diffuse cerebral and cerebellum volume loss and T2 hyperintensity within the periventricular white matter refers to a stroke. This can cause a slight decrease in the white matter of the brain.
What does posterior to the pancreatic body mean?
Posterior to the pancreatic body means that a structure or organ is located behind the body of the pancreas. In anatomical terms, it refers to the back side of the pancreas in relation to its position within the body.
Where is the wrisberg ligament located?
The ligament of Wrisberg is in the knee. It runs from the medial femoral condyle behind the posterior cruciate ligament to the posterior horn of the lateral meniscus. If the ligament runs in front of the posterior cruciate ligament, it is a ligament of Humphries.
Produces oxytocin and ADH that are released within the posterior pituitary gland?
ADH and Oxytocin is produced by hypothalamus.It is secreted by inferior pitutory.
Is Subconjunctival hemorrhage bleeding within the posterior segment of the eye?
No, a subconjunctival hemorrhage is bleeding between the conjunctiva and the sclera. It is a common and usually benign condition that appears as a bright red patch on the white part of the eye. Hemorrhages within the posterior segment of the eye would involve structures like the retina or vitreous humor.
What causes posterior urethral valves?
PUV (posterior urethral valves) is a malformtion in fetal development that results in the presence of obstructive tissue within the urethra (the thube tht leads from the bladder to the outside). If urine flow from the bladder is obstructed, urine will back up within the urinary system leading to incontinence, infection, and progressive renal damage.
What is some intrasubstance signal within the posterior horn of the medial meniscus mean?
An intrasubstance signal within the posterior horn of the medial meniscus suggests an abnormality within the tissue itself. It could indicate a meniscal tear, degeneration, or inflammation. Further imaging or clinical examination is usually needed to determine the specific cause and appropriate treatment.

d. a and b The extensors of the wrist and hand are located within the posterior compartment of the forearm and attach to the lateral epicondyle of the humerus. They do not pass through the carpal tunnel.
