Front

What is the function of the Central Nervous System (CNS)?

Back

The CNS processes input from the Peripheral Nervous System (PNS) and triggers responses as necessary.

Front

What happens to vital signs during physical activity, such as running?

Back

During running, blood pressure increases, pulse increases, and respiratory rate increases.

Front

What are sensory neurons?

Back

Nerve cells responsible for receiving external stimuli from the environment and transmitting signals to the CNS.

Front

What is the correct sequence for how a signal travels through a neuron?

Back

Dendrite -> Cell Body -> Axon -> Synapse -> Dendrite.

Front

What are single-celled organisms that do not rely on a host called?

Back

Bacteria.

Front

What is the role of the Peripheral Nervous System (PNS)?

Back

The PNS connects the CNS to the limbs and organs, facilitating communication between the brain and the rest of the body.

Front

What is the function of dendrites in a neuron?

Back

Dendrites receive signals from other neurons and transmit them to the cell body.

Front

What is the role of the axon in a neuron?

Back

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

Front

What is a synapse?

Back

A synapse is the junction between two neurons where signals are transmitted.

Front

What is homeostasis?

Back

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions.
