A neuron’s reaction of either firing with full strength or not firing
All or none
The brain & spinal cord…
Central Nervous System
Neurotransmitters carry signals across this tiny fluid filled gap between two neurons
Synaptic gap
Damage to these parts of the brain can lead to vision and hearing loss.
Vision - Occipital Lobe
Hearing - Temporal Lobe
Tendency for REM sleep to increase following nights of REM sleep deprivation
REM Rebound
A brief electrical charge that travels down an axon
Action Potential (Depolarization)
The sensory and motor nerves that connect the brain and the spinal cord to the rest of the body.
Peripheral Nervous System
The master gland that controls the rest of the glands of the endocrine system.
Pituitary Gland
Part of the brain that helps process new memories for permanent storage.
Hippocampus
Identify & explain the nickname for REM Sleep
Paradoxical Sleep
Explain the main functions of Myelin Sheath
Protects axon & enables greater transmission speed
Explain the difference between the Sympathetic and parasympathetic nervous systems.
S- Speeds up = Fight or flight
P- Slows down = Relaxed state
Explain the process of reuptake
Neurotransmitters are recycled back into terminals of presynaptic neuron
Explain the role of the thalamus
Sensory Switchboard
All but smell
Explain the key differences between NREM 3 and REM
NREM3 - Body sleep
REM - Mind sleep
A level of stimulation required to trigger a neural impulse
Threshold
The division of the peripheral nervous system that controls the glands and muscles of the internal organs.
Autonomic Nervous System
Explain the difference between an excitatory & inhibitory neurotransmitter.
Excitatory - More likely to fire
Inhibitory - Less likely to fire
Helps regulate emotions such as fear and aggression in order to maintain your fight or flight and empathy towards others.
Amygdala
Identify the 4 classifications of psychoactive drugs and an example of each
Depressant (alcohol)
Stimulant (caff/cocaine)
Opioid (heroine)
Hallucinogen (thc)
After a neuron fires, it needs to recharge in order to fire again, this is known as the…
Refractory Period → Resting Potential
(- inside/+outside)
The division of the peripheral nervous system that would help Mr. Agallar out the most in JuJitzJu as it controls is skeletal muscle movements
Somatic Nervous System
Explain how neurotransmitters and hormones are similar and different while providing 3 examples of each.
Both chemical messengers
N - Nervous system
H - Endocrine system
Melatonin/adrenaline/leptin/ghrelin/oxytocin
Explain the difference between Broca’s and Wernickie’s Area.
B - Speech production
W - Language comprehension
Left Hemisphere
Define and provide an example of an Agonist & Antagonist
Agonist - mimic, intensify, increase
- alcohol, opioid
Antagonist - block or delay
- botox, alcohol
