What does “Neuron” actually mean in Neural Control & Coordination, and why does it matter for NEET?
the nerve cell that carries impulses, with dendrites (receive), an axon (transmit) and synapses (connect).
I keep getting “Neuron” questions wrong in Neural Control & Coordination. What's the trap?
thinking the axon receives signals.
What does “Nerve impulse” actually mean in Neural Control & Coordination, and why does it matter for NEET?
an electrical signal (action potential) travels within a neuron; a chemical signal crosses the synapse.
I keep getting “Nerve impulse” questions wrong in Neural Control & Coordination. What's the trap?
thinking the impulse jumps the synapse as electricity.
What does “Reflex arc” actually mean in Neural Control & Coordination, and why does it matter for NEET?
a fast, involuntary response routed through the spinal cord without waiting for the brain.
I keep getting “Reflex arc” questions wrong in Neural Control & Coordination. What's the trap?
thinking every response goes through the brain first.
What is the difference between CNS and PNS?
The central nervous system is the brain and spinal cord (processing); the peripheral nervous system is the nerves connecting them to the body.
What is the difference between sensory neuron and motor neuron?
A sensory neuron carries signals from receptors to the CNS; a motor neuron carries commands from the CNS to muscles/glands.
What is the difference between resting potential and action potential?
Resting potential is the neuron's charged 'ready' state (about −70 mV); an action potential is the brief reversal that carries the impulse.
How is Neural Control & Coordination tested in NEET, and what should I focus on?
Prioritise the core ideas: Neuron, Nerve impulse, Reflex arc.
