    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 👍

      Umm...actually it is not necessary that motor neurons must connect to the biscep only..u can define'em as
      Those neurons that are connected with the effector muscle and yeah you can give example of the biscep muscle☺

    1.Reflex action are involntary action controlled by the spinal cord without involvement of brain .
    2. Reflex arc is a method having one sensary neuron, Reray neuron and motor neuron.
    3.sensary neuron- Transmit impulses to spinal cord.
    Reray neuron- it connect sasary neuron to motor neuron.
    Motor neuron- Transmit impulses to sensary organ.

    Reflex action - In voluntary response to a stimulus
    Reflex arc It is a path which includes the sensory ,relay and motor neurons .
    Sensory neuron - send messages from sense organs to spinal cord
    Relay - connects the sensory and motor neuron. Transfers the electric signals from sensory to motor neuron
    Motor Neuron - carry messages back from spinal cord to other muscles as well as glands.
