ANSWERS: 1) reflex action are basically involuntary action that are Done after a sudden change in our environment basically called Stimulus that is harmful for our survival . 2) a reflex arc is the connection of sensory, Neurons Relay neurons and motor neurons and The stretching back of hand After stimulus. An arc like structure is obtained So it's called reflex arc 3)Sensory neurons - these are those neurons which converts the stimulus into electric impulses and sends them to spinal cord Relay Neurons- these are basically the connection between sensory and motor neurons . The neuron that connects sensory with motor neurones are called relay neurons Motor neurones- these are those neurons which carry information To biseps muscles to contract for our survival . 4) diagram made in Notebook 👍 OP explaination 🙂
