Dlat and Kt channels.Explanation / Answer
9) The correct option is E. choroid plexus.
The choroid plexus is a plexus of cells, which produces the cerebrospinal fluid in the ventricles of the brain. if it damaged, then would produce less cerebrospinal fluid.
10) The correct option is A. Substantia nigra.
The substantia nigra is basal ganglia, which is present in the midbrain. It plays an essential role in reward and movement. Dopamine is formed by the cells of the substantia nigra. If substantia nigra stops releasing dopamine, then it is the cause of Parkinson’s disease.
11) The correct option is B. cerebral cortex.
White matter is present in all locations except the cerebral cortex.
12) The correct option is A. PNS; CNS.
Nerves are bundles of axons, which are present in the PNS. They carry signals between the brain and spinal cord and the rest of the body. Tracts are group of fibers inside the CNS. They carry information up or down the spinal cord, to or from the brain.
