Vineet’s day begins with a cup of piping hot coffee. Caffeine is a stimulant present in coffee which increases the circulation of Adrenaline in the body. Vineet feels refreshed, alert and focussed.
Name the organ that is stimulated by caffeine which makes Vineet alert and focussed.
Topic: Cerebrum
Answer
The BRAIN — specifically the CEREBRUM.
Alertness, concentration and conscious thought are functions of the CEREBRUM, the largest part of the brain, which controls intelligence, memory, reasoning and voluntary action.
Caffeine is a stimulant of the central nervous system: it blocks the chemical that normally makes us feel drowsy, so the cerebrum stays active and we feel awake.
Match the symptom to the part, which is how every brain question is answered: thinking and alertness — cerebrum; balance and coordination — cerebellum; heartbeat, breathing and other involuntary activity — medulla oblongata.
