Transmission of Impulses Notes for NEET & Class 11 Biology

  Transmission of Nerve Impulses — Easy NEET Notes  By - Dr.Sanjaykumar pawar 18.3.2 Transmission of Impulses 1. What is a nerve impulse? A nerve impulse is an electrical signal that travels through a neuron. It helps in communication between different parts of the body. 2. What is a Synapse? A synapse is the junction between two neurons. Through this junction, nerve impulses pass from one neuron to another. Structure of Synapse A synapse is formed by: Pre-synaptic neuron → neuron sending the impulse Post-synaptic neuron → neuron receiving the impulse Synaptic cleft → small gap between the two neurons Types of Synapses A. Electrical Synapse Features Pre- and post-synaptic membranes are very close. Electrical current flows directly from one neuron to another. Impulse transmission is very fast. Important Points Similar to impulse conduction along one axon. Faster than chemical synapse. Rare in humans. NEET Point No neurotransmitter is re...
