Neuron

What is the name of the part of a neuron that receives nerve impulses from other neurons?

• Dendrites

• Axons

• Synapse

• Nucleus

What is the main function of an axon in a neuron?

• Produces neurotransmitters

• Send nerve impulses from the cell body to the synapse

• Protects neurons from damage

• Receive nerve impulses from other neurons

What process occurs as a nerve impulse travels along an axon?

• Oxidation and reduction
• Transcription and translation
• Action potential

• Synapse facilitation

What is the role of neurotransmitters in the nervous system?

• Neurotransmitters transmit signals between neurons in the nervous system.
• Neurotransmitters produce energy in the nervous system.
• Neurotransmitters regulate blood flow in the nervous system.
• Neurotransmitters send signals between neurons at synapses.

Which part of a neuron contains a nucleus?

• Cell body or soma
• Dendrite
• Axon
• Synapse

How are nerve impulses transmitted across synapses?

• Through mitochondria

• 
  Through neurotransmitters

• Through the cytoplasm

• Through calcium ions

What chemicals are used to transmit nerve signals between neurons?

• Hormones
• Enzymes
• Neurotransmitters
• Antibodies

What is the name of the cells that form myelin to protect axons?

• Oligodendrocytes (CNS) and Schwann cells (PNS)
• Astrocytes
• Microglia
• Erythrocytes

What type of neuron carries impulses from the brain to the muscles?

• Sensory neurons
• Interneurons
• Motor neurons
• Visual neurons

What happens when a neurotransmitter is released into a synapse?

• The neurotransmitter remains in the presynaptic neuron
• The neurotransmitter diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane.
• The neurotransmitter is destroyed immediately
• The neurotransmitter causes the synapse to expand
