Document Summary
Q collar constricts your jugular vein and increases volume around your brain to decrease concussions. Need the specific amount of pressure on neck to effectively increase fluid in the brain. Hydrating and drinking more water will increase fluid volume, the more fluid then in your body your brain will not bounce freely. Mouth-guards are shown to decrease the severity of a concussion; can decrease the amount of time it takes to recover from a concussion. These fibres are organized in the posterior section of the spinal cord with innervation from sacral, lumbar, thoracic, and cervical. Primary motor cortex (m1, also called brodmanns area 4) Premotor (pma) and supplementary (sma) motor cortices (brodmanns area 6) Descending pyramidal pathway receives most projections from frontal motor areas primarily from m1 (primary motor cortex) or also known as brodmann"s are 4. M1, sma, pma comprise of 60% of the descending fibres of the pyramidal tract.
