100

This system is made up of the brain, spinal cord, and nerves.

what is the nervous system?

100

This part of a neuron receives signals from other neurons or sensory receptors.


what is the dendrite?
100

These neurons carry signals from sensory receptors to the CNS.

What are sensory neurons?

100

This is the largest part of the brain, responsible for reasoning, problem-solving, and voluntary muscle movements.

What is the cerebrum?

100

This structure connects the brain to the rest of the body and is protected by the vertebral column.

What is the spinal cord?

200

This part of the nervous system includes the brain and spinal cord.

What is the Central Nervous System (CNS)?

200

This part of the neuron contains the nucleus and is the control center of the cell.

What is the cell body?

200

These neurons transmit commands from the CNS to muscles or glands.

What are motor neurons?

200

This part of the brain controls balance, coordination, and fine motor skills.

What is the cerebellum?

200

This response is triggered by a sudden stimulus and is processed at the spinal cord, often before the brain receives the signal.

What is the fight or flight response?

300

The network of nerves that extends throughout the body, outside of the brain and spinal cord, is known as this.

What is the Peripheral Nervous System (PNS)?

300

This long, slender part of a neuron transmits electrical impulses away from the cell body.

What is the axon?

300

These neurons are responsible for processing information within the CNS and connecting sensory and motor neurons.

What are interneurons?

300

This part of the brain controls basic life functions like breathing and heart rate.

What is the medulla oblongata?

300

In this type of reflex, the spinal cord processes the response directly without involving the brain.

What is a spinal reflex?

400

This division of the peripheral nervous system controls involuntary actions like heartbeat and digestion.

What is the Autonomic Nervous System?

400

This insulating layer around the axon helps speed up the transmission of nerve impulses.

What is myelin?

400

This term refers to the rapid transmission of a nerve impulse along a neuron.

What is a nerve impulse?

400

The part of the brain that is responsible for emotions and memory is this.

What is the limbic system?

400

This is the sequence in which a nerve impulse travels: from dendrites, through the cell body, down the axon, and across the synapse.

What is the path of a nerve impulse?

500

The primary function of this system is to transmit signals from the body to the brain and vice versa.

What is the nervous system?

500

The gap between two neurons, across which nerve impulses travel, is called this.

What is the synapse?

500

This reflex action involves an immediate, automatic response to a stimulus, without involving the brain.

What is a reflex?

500

This part of the brain connects the brain to the spinal cord and controls essential life-sustaining functions.

What is the brainstem?

500

This is the process by which neurons communicate with each other through chemical signals across the synapse.

What is synaptic transmission?
