Nervous System Flashcards

Front

What is the nervous system responsible for?

Back

The nervous system is responsible for sending messages back and forth between the brain and the body, involving all of our 5 senses. It responds to stimuli and coordinates activities of other systems.

Front

What makes up the Central Nervous System?

Back

The Central Nervous System is made up of the brain and spinal cord.

Front

What is the function of the brain in the nervous system?

Back

The brain processes incoming messages, resulting in the storage of memories or the sending out of messages to motor neurons to produce actions.

Front

What is the role of the spinal cord?

Back

The spinal cord carries messages from the sensory neurons to the brain and from the brain to the motor neurons.

Front

What does the Peripheral Nervous System include?

Back

The Peripheral Nervous System includes the nerves that carry messages to and from the brain and spinal cord to the rest of the body.

Front

What is a sensory neuron?

Back

A sensory neuron is a nerve cell in the nervous system attached to a sense organ (e.g., eye), which receives messages from the body’s outside environment and passes it towards the brain or spinal cord.

Front

What is a motor neuron?

Back

A motor neuron is a nerve cell in the nervous system attached to an effector cell (e.g., muscle), which receives messages from the spinal cord and triggers a response.

Front

What is a stimulus?

Back

A stimulus is something that creates a response in the body and can be seen, heard, smelt, felt, or tasted.

Front

What is a response in the context of the nervous system?

Back

A response is a behavior (e.g., action, thought, or stored memory) that results from a stimulus.
