Fissure filling is a treatment that improves the apparent clarity of a gemstone by removing air and replacing it with a substance that has a refractive index similar to the host material. Many different substances may be used to fill fissures: oils, resins, waxes, glass, and various polymers, to name a few.
Cerebral autoregulation is a process in mammals, which aims to maintain adequate and stable cerebral blood flow.hile most systems of the body show some degree of autoregulation, the brain is very sensitive to over-and underperfusion. Cerebral autoregulation plays an important role in maintaining an appropriate blood flow to that region.
By processing inputs received from the cerebral motor cortex, various brain stem nuclei, and sensory receptors, the cerebellum provides the precise timing and appropriate patterns of skeletal muscle contraction for smooth, coordinated movements and agility needing for our daily lives (e.g., driving).xercise 1: Utilize the model of the human brain to locate the following structures / landmarks for the cerebrum: ï· Longitudinal fissure ï· ï·Frontal lobe ï· Parietal lobe ï· Central sulcus ï· Precentral gyrus D IENCEPHALON: Surrounded by the cerebral hemispheres, the diencephalon forms the central core of the brain.
