M2L1 Neurotransmission

excite the next cell into firing

• Glutamate
• Acetylcholine (ACh)
• inhibitory neurotransmitters
• excitatory neurotransmitters

a neural impulse; a brief electrical charge that travels down an axon

• all-or-none response
• Neurotransmitters
• membrane voltage
• action potential

Deterioration of the myelin sheath can lead to motor impairments, such as

• all-or-none response
• resting state
• membrane voltage
• multiple sclerosis

the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron

• dopamine
• Axon
• Synapse
• Dendrites

the basic building block of the nervous system

• dopamine
• Neuron
• Serotonin
• threshold

Small knobs at the end of axons that secrete chemicals called neurotransmitters

• Neurotransmitters
• terminal buttons
• dendrites
• membrane

cell body

• serotonin
• GABA
• soma
• axon

A layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next.

• myelin sheath
• Neurotransmitters
• terminal buttons
• action potential

Branchlike parts of a neuron that are specialized to receive information.

• myelin sheath
• dendrites
• terminal buttons
• action potential

the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands

• neuron
• axon
• synapse
• depolarization
