The Nervous System

Front

What is the all-or-none response in neurons?

Back

The all-or-none response is a principle stating that if a neuron responds at all, it responds completely, meaning it either fires an action potential or it does not fire at all.

Front

What type of neuron connects sensory neurons to motor neurons?

Back

Interneurons are the type of neurons that connect sensory neurons to motor neurons.

Front

Which part of a neuron is responsible for receiving messages?

Back

Dendrites are the part of a neuron that receives messages from other neurons.

Front

What is the function of interneurons?

Back

Interneurons connect sensory neurons to motor neurons and are involved in processing information within the central nervous system.

Front

What is a synapse?

Back

A synapse is the gap that a message has to cross to get from one neuron to another.

Front

What are the three main types of neurons?

Back

The three main types of neurons are sensory neurons, motor neurons, and interneurons.

Front

What is the role of sensory neurons?

Back

Sensory neurons carry signals from sensory receptors to the central nervous system.

Front

What is the role of motor neurons?

Back

Motor neurons transmit signals from the central nervous system to muscles or glands to elicit a response.

Front

What is the function of the axon in a neuron?

Back

The axon transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What are glial cells?

Back

Glial cells are non-neuronal cells in the nervous system that support, nourish, and protect neurons.
