Explore the Brain and Neurons

What is the largest part of the brain?

• Thalamus

• Brainstem

• Cerebrum

• Cerebellum

Which part of the brain is responsible for balance and coordination?

• Cerebellum

• Cerebrum

• Brainstem

• Thalamus

What is the function of the cerebellum?

• Processing visual information and perception.

• Regulation of heart rate and blood pressure.

• Coordination of voluntary movements and balance.

• Production of hormones and metabolic functions.

What are the three main parts of a neuron?

• cell body, dendrites, axon

• dendritic spines, soma, axon hillock

• axon terminals, glial cells, myelin

• soma, synapse, neurotransmitter

What is the role of dendrites in a neuron?

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

• Dendrites send signals away from the cell body.

• Dendrites are responsible for producing neurotransmitters.

• Dendrites protect the neuron from damage.

What part of the brain controls breathing and heart rate?

• Cerebellum

• Thalamus

• Frontal lobe

• Brainstem (medulla oblongata and pons)

What is the myelin sheath and its function?

• The myelin sheath is a protective covering around axons that insulates them and increases the speed of electrical impulses.

• The myelin sheath is a structure that connects neurons to muscles for movement.

• The myelin sheath is a type of neurotransmitter that transmits signals between neurons.

• The myelin sheath is a layer of fat that stores energy for the neuron.

Which part of the brain is known as the 'thinking' part?

• Brainstem

• Cerebral cortex

• Cerebellum

• Thalamus

What is the function of the axon in a neuron?

• The axon receives signals from other neurons.

• The axon stores neurotransmitters for later use.

• The axon transmits electrical impulses away from the neuron's cell body.

• The axon protects the neuron from damage.

There are approximately how many neurons in a body

• 80 billion

• 80 million

• 86 billion

• 86 million
