Hormones
this hormone plays a key role in fight-or-flight response
this neurotransmitter is crucial for muscle movement
dopamine
this brain disease is characterized by memory loss and confusion
this part of the neuron receives signals
dendrite
this part is responsible for coordinating voluntary movements and balance
this hormone regulates the sleep-wake cycle
melatonin
this neurotransmitter is primarily associated with the regulation of mood, sleep, and appetite
serotonin
this disease affects movement and is caused by death of dopamine-producing neurons in the brain
parkinsons
this structure transmits electrical impulses away from the neuron's cell body
axon
this part of the nervous system includes the brain and spinal cord
central nervous system
this hormone helps the body respond to stress
cortisol
this neurotransmitter is also known as adrenaline
epinephrine
this condition is marked by unprovoked seizures due to abnormal electrical activity in the brain
epilepsy
this type of neuron carries signals from the sensory organs to the central nervous system
sensory neuron
these cells are the basic building blocks of the nervous system
neurons
this hormone helps regulate blood sugar levels
insulin
this neurotransmitter is involved in learning and memory
glutamate
this autoimmune disease attacks the protective covering of nerves, leading to communication problems between the brain and the rest of the body
multiple sclerosis
this is the gap between two neurons where neurotransmitters are released
synapse
these cells support and protect neurons in the central nervous system
glial cells
this hormone regulates metabolism
thyroxine
this neurotransmitter helps reduce neuronal excitability throughout the nervous system
gamma-aminobutyric acid (GABA)
this rare disease causes rapid neurodegeneration and is often linked to prion proteins
creutzfeldt-jakob disease
this part of the neuron contains the nucleus and is essential for the cell's metabolic activities
cell body (soma)
this system includes all the nerves outside the brain and spinal cord
peripheral nervous system
