Reflex Arc

Front

What is a reflex arc?

Back

A reflex arc is a neural pathway that controls a reflex action. It typically involves a sensory neuron, an interneuron, and a motor neuron.

Front

Where are receptors found?

Back

In a sense organ (e.g., the eye, skin, tongue).

Front

What type of neuron is responsible for transmitting signals from receptors to the central nervous system?

Back

Sensory neuron.

Front

What type of neuron connects sensory and motor neurons?

Back

Relay neuron (interneuron).

Front

What type of neuron carries signals from the central nervous system to effectors?

Back

Motor neuron.

Front

What is an effector in the context of a reflex arc?

Back

An effector is a muscle or gland that responds to a stimulus, such as a muscle contracting.

Front

What is a key feature of reflex actions?

Back

Reflex actions are rapid and involuntary.

Front

What role do sensory neurons play in a reflex arc?

Back

Sensory neurons detect stimuli and transmit signals to the central nervous system.

Front

What is the function of motor neurons in a reflex arc?

Back

Motor neurons transmit signals from the central nervous system to effectors to produce a response.

Front

What is the role of interneurons in a reflex arc?

Back

Interneurons process information and connect sensory and motor neurons.
