Introduction to Muscle Contraction

A nerve cell

• Axon
• Muscle fiber
• Neuron
• Neurotransmitter

Projection that extends away from a nerve cell and is capable of conducting action potentials away from the nerve cell

• Neuron
• Neurotransmitter
• Synapse
• Axon

Connection between the axon the muscle

• Synapse
• Neurotransmitter
• Motor Neuron
• Axon

A chemical that an axon end secretes into a synapse

• Neurotransmitter
• Synaptic Cleft
• Neuron
• Axon

A neuron that conducts impulses to create a response/an effect

• Motor Neuron
• Axon
• Muscle Fiber
• Synapse

The synapse where a motor neuron axon and a skeletal muscle fiber meet

• Neurotransmitter
• Neuron
• Axon
• Neuromuscular Junction

Where the sarcolemma is extensively folded and nuclei and mitochondria are abundant

• Neurotransmitter
• Motor End Plate
• Axon
• Acetylcholine

The small gap that separates the neuron and muscle fiber

• Axon
• Neurotransmitter
• Synaptic Cleft
• Synapse

How to neurons communicate with muscle cells?

• By releasing antibodies
• By releasing neurotransmitters
• By making a phone call
• Morse Code

How do neurotransmitters get from the neuron to the muscle fiber?

• By diffusing across the synaptic cleft
• By jumping across the synaptic cleft
• Teleportation
• By sliding across the synaptic cleft attached to a protein
