Understanding Reflex Arcs

What is a reflex arc?

• A neural pathway for reflex actions

• A type of bone

• A type of muscle

• A part of the brain

Which type of reflex involves skeletal muscles?

• Autonomic reflexes

• Smooth muscle reflexes

• Somatic reflexes

• Cardiac reflexes

What is the first component of a reflex arc?

• Motor neuron

• Interneuron

• Effector

• Receptor

Which component of the reflex arc is responsible for making decisions?

• Sensory neuron

• Motor neuron

• Interneuron

• Effector

What role does the brain play in reflex actions?

• It is not involved in reflex actions

• It controls primitive reflexes

• It is responsible for reflexes like sneezing and blinking

• It only processes voluntary actions

In a simple reflex arc, where does the information go after the sensory neuron?

• To the central nervous system

• To the motor neuron

• Directly to the effector

• To the brain

What is the final component in a reflex arc?

• Effector

• Interneuron

• Sensory neuron

• Receptor

Why are reflex arcs important for homeostasis?

• They only function during sleep

• They slow down body responses

• They help in quick responses to stimuli

• They are not related to homeostasis

Which of the following is an example of a reflex action?

• Eating

• Walking

• Reading

• Breathing

What is the primary purpose of reflex arcs?

• To enhance muscle growth

• To maintain balance

• To ensure quick responses and safety

• To improve memory
