What are the 7 main steps in a reflex arc?
Reflex arcs
- Receptor in the skin detects a stimulus (the change in temperature).
- Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS.
- Motor neuron sends electrical impulses to an effector.
- Effector produces a response (muscle contracts to move hand away).
What are the 4 steps of a reflex action?
Reflex actions
- Receptor in the skin detects a stimulus (the change in temperature).
- Sensory neurone sends impulses to relay neurone .
- Motor neurone sends impulses to effector.
- Effector produces a response (muscle contracts to move hand away).
Which is the correct order of events in a reflex arc quizlet?
Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) sensory receptor activation, 4) Information processing, 5) effector response.
Which of the following is the correct order of the reflex arc?
Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.
What is reflex arc 11th?
REFLEX ARC: Reflex arc is the nerve pathway involved in a reflex action, including at its simplest a sensory nerve and a motor nerve with a synapse between. Reflex arc consist of 1)Receptor or sensory organ, 2)Sensory neurine, 3)Reflex centre(brain or spinal cord), 4)Motor neurone and 5)Effector(muscle or gland). Q2.
Which of the following is the correct sequence of structures in a reflex arc?
The correct sequence of the components in a reflex is the Receptor → Sensory neuron → Spinal cord → Motor neuron → Muscle.
What is reflex action explain with example and diagram?
(a) Reflex action is a rapid and automatic response to a stimulus. It is not under the voluntary control of the brain. For example, if we unknowingly touch a hot plate, we immediately move our hand away from it. (b) The path travelled by an impulse during a reflex action is called a reflex arc.
What is the order of components of a reflex arc?
So, the correct answer is ‘Receptors – Sensory neuron – Spinal cord – Motor neuron – Muscle’
Which is the correct order of the parts of a reflex arc quizlet?
sensory receptors activated, impulse sent to CNS, sensation, perception.
