In botany, the theca is related to plant's flower anatomy. The theca of an angiosperm consists of a pair of microsporangia that are adjacent to each other and share a common area of dehiscence called the stomium. [1] Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament.
Cerebral Edema that resulted from brain tumor is represented by darker areas on this CT image. An increase in cerebral water content is called cerebral edema and it usually results from traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), subdural hematoma, ischemic stroke, brain tumors, infectious disorders and intracranial surgery.
Amen Clinics is a group of mental and physical health clinics that work on the treatment of mood and behavior disorders. It was founded in 1989 by Daniel G. Amen, a self-help author and psychiatrist. [1] [2] The clinics perform clinical evaluations and brain SPECT (single photon emission computed tomography) imaging to diagnose and treat their ...
Encephalartos villosus microsporophylls with microsporangia. A microsporangium (pl. microsporangia) is a sporangium that produces microspores that give rise to male gametophytes when they germinate. Microsporangia occur in all vascular plants that have heterosporic life cycles, such as seed plants, spike mosses and the aquatic fern genus Azolla.
The thecal sac or dural sac is the membranous sheath (theca) or tube of dura mater that surrounds the spinal cord and the cauda equina.The thecal sac contains the cerebrospinal fluid which provides nutrients and buoyancy to the spinal cord. [1]
Besides helping grow the program, McGarry also helped expand the initiative's focus to helping those students find meaningful careers upon graduation. When he started at the initiative's leader ...
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta- human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
