Welcome back Tshiamo127❤️🩹🥹 — missed you this week. 1.5.1: The diagram illustrates the pathway of a nerve impulse from a receptor to an effector, which is known as a reflex arc. Heading: Reflex Arc 1.5.2: • Neuron A: This neuron is located within the central nervous system (spinal cord) and connects the sensory neuron to the motor neuron. It is an interneuron (or relay neuron). • Neuron B: This neuron transmits impulses from the receptors in the fingers towards the central nervous system. It is a sensory neuron. • Neuron C: This neuron transmits impulses from the central nervous system to the muscles in the hand, causing a response. It is a motor neuron. 1.5.3: The microscopic gap between neuron A (interneuron) and neuron C (motor neuron) is where neurotransmitters are released to transmit the signal. The gap is called a synapse. Send me the next one 📸
