Chapter 3 pt.3 Flashcards
What makes communication between cells possible?
neurotransmitters
What determines whether an NT will bind to a cell?
It’s shapes/chemical composition
List the different type of neurotransmitters?
- acetylcholine
- serotonin
- Norepinephrine
- Dopamine
Which neurotransmitter is this: deals with movement
acetylcholine
Which neurotransmitter is this: deals with sleep & wakefulness. When this is low it can lead to depression.
serotonin
Which neurotransmitter is this: when this is low it can lead to depression.
norepinephrine
Which neurotransmitter is this: when this is low it can lead to schizophrenia or Parkinson’s disease.
dopamine
Which neurotransmitter is this: changes underlie effects of cocaine and amphetamines
dopamine & norepinephrine
Why do certain drugs have an effect on us?
because their structure haas the same shape as an NT and can modify neuronal transmission!
What section of the brain is influenced by sedatives and alcohol?
GABA
What plays a role in the effects of narcotics?
Opiate receptors & dopamine
Structure of Nervous System: what are the two main sections of the nervous system?
1, Central Nervous System
2. Peripheral nervous system
Structure of Nervous System: what does the central nervous system consist of?
- brain
2. spinal cord
Structure of Nervous System: what two systems are under the peripheral nervous system?
- Somatic nervous system
2. autonomic nervous system
Structure of Nervous System: what are the two systems under the autonomic nervous system?
- sympathetic nervous system
2. parasympathetic nervous system
Structure of the brain: what are the three main sections of the brain?
- hindbrain
- midbrain
- forebrain
Structure of the brain: what are the structures of the hindbrain?
medulla
pons
cerebellum
Structure of the brain: which part of the hindbrain is responsible for breathing & circulation?
medulla
Structure of the brain: which part of the hindbrain is responsible for sleep and arousal?
pons
Structure of the brain: which part of the hindbrain is responsible for coordination of movement and sense of equilibrium
cerebellum
What is the first area of your brain affected by alcohol (not GABA)?
cerebellum
Structure of the brain: which section (of the three main sections) brain uses integration of sensory inputs?
midbrain
Structure of the brain: in the midbrain what to structures contribute to the integration of sensory inputs?
- inferior colliculus (auditory)
- superior colliculus (visual)
Structure of the brain:
In the midbrain which is responsible for auditory and visual senses, respectively.
1. inferior colliculus (________)
2. superior colliculus (_______)
inferior colliculus (auditory) superior colliculus (visual)
