Answers
- When we touch any hot object we immediately withdraw our hands, this is due to phenomenon known as reflex action. In reflex action, sensory nerve endings present in our skin detect the heat and transfer the signal to the spinal cord. The spinal cord then coordinates the response and causes the muscles to move.
- Sanskrit is a language.When language is used to convey information to us, the activated part of the brain depends on the means of input.Reading words or viewing sign languages uses the optic nerves and the visual cortex in the brain.Spoken language uses the auditory nerves and the auditory cortex.
- When we read a joyful book,we feel joy in our neurotransmitters, which are tiny chemical “messenger” cells that transmit signals between neurons (nerves) and other bodily cells.Those neurotransmitters are responsible for processes and feelings in almost every aspect of the body, from blood flow to digestion.
