• Effector Neuron

• Sensory Neuron

• Motor Neuron

In a typical reflex arc, where does the 'integration' or decision-making step usually occur?

• The Peripheral Nerves

  
  

• The Spinal Cord

  
  

• The Receptor

  
  

• The Cerebral Cortex

  
  

What is the primary biological advantage of a reflex arc by passing the conscious brain?

• It results in a faster response time to protect the body from harm.

  
  

• It prevents the sensory neurons from becoming overworked.

  
  

• It allows the body to conserve energy by using fewer neurons.

  
  

•     It ensures that the muscles move with more physical force

What is the correct order of components in a reflex arc pathway?

• Interneuron → Sensory Neuron → Receptor → Effector → Motor Neuron

  
  

• Effector → Motor Neuron → Interneuron → Sensory Neuron → Receptor

• Receptor → Motor Neuron → Interneuron → Sensory Neuron → Effector

• Receptor → Sensory Neuron → Interneuron → Motor Neuron → Effector

  
  

An effector is the final component of the reflex arc. Which of the following best describes an effector?

• The gap between two neurons where chemicals are released.

  
  

• A muscle or gland that carries out the physical response.

  
  

• The fatty layer that speeds up the nerve impulse.

  
  

• A specialized protein that detects heat or pressure.
