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)
Structure of the brain:
In the midbrain which is responsible for auditory and visual senses, respectively.
1. _________ colliculus (auditory)
2. _________ colliculus (visual)
- inferior
2. superior
Structure of the brain: In the midbrain, what does the substantia Nigra do?
dopamine projections originate here
Structure of the brain: depletion of neurons in the Substantia Nigra causes __________
Parkinson’s
Structure of the brain: depletion of neurons in the _________ ______ causes Parkinson’s
Substantia Nigra
Strucuture of the brain: Reticular formation occurs in what three main sections of the brain?
midbrain
Structure of the brain: What is the largest region of the brain?
forebrain
Structure of the brain: List the systems located in the forebrain section of the brain.
- thalamus
- hypothalamus
- limbic system
- cerebrum
Structure of the brain: What is the difference between the thalamus and the hypothalamus?
The thalamus relays center for senses (except smell)
The hypothalamus regulates basic biological needs (ie hunger, thirst, sex)
Structure of the brain: loosely connected network of structures, including hippocampus and amygdala
limbic system
Structure of the brain: the limbic system includes the ____________ and _________
hippocampus
amygdala
Structure of the brain: the reward pathway travels through the ______ ________
lymbic system
Structure of the brain: the brain is divided into right and left hemispheres; and connected by the ________ ________
corpus callosum
Structure of the brain: What are the four lobes in the forebrain?
- Optical lobe
- Parietal lobe
- Temporal lobe
- Frontal lobe
Structure of the brain: what is the optical lobe for?
primary visual cortex
Structure of the brain: what is the parietal lobe for?
primary somatosensory cortex (touch)
Structure of the brain: what is the temporal lobe for?
primary auditory cortex
Structure of the brain: what is the frontal lobe for?
primary motor cortex (movement of body parts)
Structure of the brain: what is the prefrontal cortex for?
executive control system
