Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
The plant goes into shock
The correct terms to fill in the blanks are lateral ventricles and venous sinus blood. Cerebrospinal fluid (CSF) is formed by lateral ventricles and reabsorbed through arachnoid granulations into the venous sinus blood. The CSF is a fluid that is clear and colorless found in the spinal cord and in the brain, generally the central nervous system. The CSF functions as a buffer or a shock absorber for the brain. It provides basic mechanical protection for the brain. Also, it helps in the circulation of nutrients and the chemicals that are filtered and aids in the elimination of waste products.
