Chapter 3 Flashcards
Sympathetic Nervous System
Fight or flight
When the ions of a neuron are imbalanced, the neuron cannot initiate another action potential, and is in a___
Refractory period
Your sister has depression. You notice that after she went to the doctor the other day, she had a new prescription for an SSRI. This is___
Selective Serotonin Reuptake Inhibitor
Serotonin
If you are having disruptions in sleep, being overly reactive, no patience, but find that you feel better when you eat healthy
Norepinephrine
If you find that you are always aroused or activated (maybe your brain can’t shut off)
Glutamate
Major excitatory neurotransmitter-affected by alcohol
Dopamine
Being outside and getting physical activity can increase the levels of it
If we were to electrically stimulate a certain area of the hypothalamus of a rat it would…
Give up food and water to push a lever for stimulation
We only use 50% of our brains
False
Your inability to get out of bed might be a deficit in this area
Reticular Formation
Being unable to dance because you can’t coordinate your balance and movements is due to
dysfunction in the cerebellum
Having a difficult time regulating your body temperature might be because this area is not functioning properly
Hypothalamus
When a person has a stroke, their face, arm, and hand on one side of their body may go limp. This is likely due to lack of blood flow to___
The Motor & Sensory cortex area of the brain
If you were having trouble sleeping you might take a supplement called melatonin. This deals with which gland of the endocrine system?
Pineal
As you are playing tennis you hear a pop in your chest and you are suddenly in pain. Which area of the brain would allow you to feel this pain inside your body?
Insular Cortex
Wallace has recently started approaching total strangers on the street. At first his friends were amused by this behavior, but lately Wallace has walked up to some scary-looking people. He has a damaged___
Amygdala
One day, the professor was out fishing and received some head trauma… now when people talk to him it all sounds like gibberish. It is likely he has___
Wernikies Aphasia
If there is a damage that requires Neuroplasticity, adult brains are less able to rewire as a young persons
True
Parasympathetic Nervous System
Returns body to resting state by counteracting and complementing actions of sympathetic nervous system
Somatic Nervous System
Allows you to feel external sensations and control willful movements
Limbic System
regulates emotions, memory, behavior, and motivation
Central Nervous System
System composed of the brain and spinal cord; exchanges info and connects to PNS
When the human brain develops the more primitive parts develop first
True
Neurons that exist in your body
Sensory Neurons, Interneurons, Motor Neurons, and Mirror Neurons
Agonist
A chemical that mimic the action of a neurtransmitter
What is the difference between an MRI and a fMRI?
MRI takes scans of oxygen in blood flow through brain to see deeper in brain and fMRI takes multiple of these scans
What is reuptake?
Maintains balance of existing neurotransmitters, reabsorbed by vesicles
What is Broca’s Aphasia?
impacts ability in speech and ability to communicate
What does SSRI stand for and what is its function?
Selective Serotonin Reuptake Inhibitor, most commonly prescribed for depression allows the neurons to be fired more frequently
Autonomic
allows you to feel internal sensations and control autonomic movement (ex: heartbeating)
What is neural plasticity?
brains capacity to regenerate and reinvent itself over lifetime
