The order of sequence of tissues involved in producing of a reflex action when a bright light is focused on the eye would be
The order of sequence of tissues involved in producing of a reflex action when a bright light is focused on the eye would be
The correct option is B receptor, sensory neuron, relay neuron, motor neuron, effector
The correct option is B.
Explanation of the correct option:
- Reflex arc is the sensory mechanism that controls a reflex action.
- Automatic response to the action of a stimulus is called reflex action.
- The sensory cells carry the input from the receptor impulses to a central interneuron, which makes contact with a motor neuron to produce a reflex.
- The order of correct sequence of reflex action includes: receptor----sensory neuron----relay neuron----motor neuron----effector.
Explanation of the incorrect options:
Option A:
The sequence of tissues involved in producing a reflex action will not be in the order of effector, sensory neuron, relay neuron, motor neuron, receptor.
Option C:
The sequence of tissues involved in producing a reflex action will not be in the order of effector, motor neuron, relay neuron, sensory neuron, receptor.
Option D:
The sequence of tissues involved in producing a reflex action will not be in the order of receptor, motor neuron, relay neuron, sensory neuron, effector.
Final answer: The order of sequence of tissues involved in producing a reflex action when a bright light is focused on the eye would be receptor, sensory neuron, relay neuron, motor neuron, effector.
