Q1: What is the difference between a reflex action and walking?
Answer:
A reflex action is an involuntary action that is a rapid and automatic response to stimuli. Walking is a voluntary action, which requires our thinking and is within our control.
Q2: What happens at the synapse between two neurons?
Answer:
At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter. The neurotransmitter can either help (excite) or hinder (inhibit) neuron B from firing its own action potential.
Q3: Which part of the brain maintains posture and equilibrium of the body?
Answer:
Cerebellum, part of the Hindbrain is responsible for maintaining posture and equilibrium of the body.
Q4: How do we detect the smell of an agarbatti (incense stick)?
Answer:
Smell of an incense stick is detected by the olfactory receptors present in the nose. The receptors send the signal to the olfactory lobe present in the fore-brain where it is analyzed and reacted upon.
Q5: What is the role of the brain in reflex action?
Answer:
The brain is not involved in a reflex action as it is an involuntary action that does not require thinking.
