Which one is main fuel for brain?
1 Glucose
2 Riboflavin
3 Ornithine
4 Glutamic acid
Explanation:
A Glucose is the essential metabolic fuel for the brain. Acute \& severe reduction of glucose in brain leads to quickly impairment of cognitive \& reflex function. When the brain does not have enough glucose, it can start to break down other nutrients for energy, such as protein.

Axons serve to
1 take away impulse from cytons
2 bring impulse to cytons
3 bring blood to heart
4 None of the above
Explanation:
A Axons take away impulse from cytons. Axon transmits nerve impulses away from the cell body (cyton) of a neuron. They carry signals to other neurons, muscles, or glands.

Number of brain cells dead at the age of 70 years constitutes
1 \(10 \%\)
2 \(20 \%\)
3 \(30 \%\)
4 \(55 \%\)
Explanation:
B As the age growing the brain cell begin to degenerate due to decline in white matter. The myelin sheath started decline after the age of 40 which causes of ageing. The late myelinting regions of the frontal lobes are most affected by white matter. \(20 \%\) brain cells dead at the age of 70 years naturally.

In a myelinated neuron, two adjacent myelin sheaths are separated by gaps called
1 Nodes of Ranvier
2 Synaptic cleft
3 Schwann cells
4 Synaptic knob
5 Neural plate
Explanation:
A The gaps between two Adjacent myelin sheaths in a myelinated neuron are called nodes of Ranvier. The synaptic cleft is the gap between the axon of one neuron and the dendrite of another neuron. Schwann cells are the cells that form the myelin sheath. The synaptic knobs is the end of the axon that forms the synapse. The neural plate is a structure in the embryo that develops into the nervous system.
A Glucose is the essential metabolic fuel for the brain. Acute \& severe reduction of glucose in brain leads to quickly impairment of cognitive \& reflex function. When the brain does not have enough glucose, it can start to break down other nutrients for energy, such as protein.
