Nervous System Flashcard

Front

What type of neurons transmit signals from the central nervous system to muscles?

Back

Motor neurons transmit signals from the central nervous system to muscles, instructing them to move.

Front

What is the mechanoreceptor that allows us to feel pain and does not adapt?

Back

Nociceptors are the type of mechanoreceptors that allow us to feel pain and do not adapt.

Front

Approximately how many neurons are in the human brain?

Back

There are about 100 billion neurons in the human brain.

Front

What part of the nervous system consists of the brain and spinal cord?

Back

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

Front

What part of the nervous system includes all of the body's nerves?

Back

The Peripheral Nervous System (PNS) is made up of all the body's nerves.

Front

What is the function of sensory neurons?

Back

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

Front

What is the role of interneurons in the nervous system?

Back

Interneurons connect sensory and motor neurons and process information within the central nervous system.

Front

What is the primary function of the central nervous system?

Back

The central nervous system processes information and coordinates responses throughout the body.

Front

What is the difference between the central and peripheral nervous systems?

Back

The central nervous system consists of the brain and spinal cord, while the peripheral nervous system includes all other nerves in the body.

Front

What are reflex actions and how do they occur?

Back

Reflex actions are automatic responses to stimuli that occur via a reflex arc, involving sensory neurons, interneurons, and motor neurons.
