Depends on damage: The spinal cord serves as a conduit for information to/from the brain.If cord injury is minor(brief compression/shock) the information transfer may stop for a time & return after any swelling/etc.Is gone. If the injury kills a segment of the cord, the sensation below the segment is lost and voluntary control of muscles below the injury is gone (permanent paralysis). Reflex mvt may persist. ...Read moreSee 1 more doctor answer
What happens when neurons die by injury!? Specific neurons in the brain , injury to the central nervous system.
In most cases: neurons do not have the ability to regenerate, or have only a limited ability at best. There is significant redundancy and unused capacity with the brain's neural network, so depending on the location and extent of injury, it may be possible to compensate for some degree of neuronal loss due to injury. The damage itself is generally permanent, however. ...Read more
What duration of full body Anesthesia will cause damage to the brain? Will that decrease your IQ? Is the brain unrecoverable from the damage?
Odd question: Where did you get the idea that anesthesia causes brain damage? Anesthesia is a controlled sequence of dropping sensation but while preserving/supporting body functions like breathing, oxygen exchange, fluid balance. These do not damage if done properly. If your question is really about coma, the involuntary loss of consciousness,outcome is determined by the cause of the coma. ...Read more
TFCC is both: It is a carticalginous strucutre that blends into ligmants. That is why it has "fibro" like a ligament. "cartilage" and COMPLEX in its name. THe central disc part is cartilage that cushions but it has a thickened vascular rim that provdde ligamenteouis like structure, the ulnar ligmanets of hte wrsit and the tendin sheath of the ecu blend into this. Think of a sail with supports, rigging ...Read moreSee 3 more doctor answers
What is the initial treatment, by the emt's, for brain injury in an infant to prevent further brain damage?
ABC's: Airway, breathing, circulation. These are the tenets of "in the field" first aid. They establish an airway (can be basic or actual endotracheal tube), breathing (mouth to mouth or bag/mask ventilation can also give oxygen) and (circulation: chest compressions)... That is generally all that is at their disposal. ...Read moreSee 1 more doctor answer
Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?
Feedforward/feedback: Hi. Hypothalamus important, but to keep it simple, pituitary ACTH stimulates the adrenal cortex to make cortisol. Cortisol negatively feeds back to suppress pituitary ACTH. If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more
Multiple problems: in older folks, local strokes, either from end arteries within stem, or without in vertebrobasilar circulation. Might have significant trauma causing vertebral artery dissection. Can see midline posterior tumors, mainly in children. Can be an area of involvement in multiple sclerosis, vasculitis, sarcoidosis, Lyme disease, etc. If there seems localized damage, an answer is needed. ...Read more
What injury of the knee could lead to pain behind the kneecap and the inability to fully extend the leg?
Yes.: If the vagus nerve is injured during surgery, the function of it will be affected. This can either be temporary or permanent, based on whether the nerve was just stretched or cut. Surgery of the foregut, which includes the esophagus and stomach, are the most common surgeries that can injure the vagus nerve. ...Read more
Is temporalis muscle wasting after craniotomy due to disruption of blood flow (retraction), or to damage to the motor branch of the trigeminal nerve?
Likely not nerve: Temporalis wasting is probably from transection and reattachment of the muscle, retraction, as well undermining and devascularing it, often with the use of cautery. ...Read more
