The two positively charged ions used during an action potential are?
K+ and Na+
100
Vision is controlled by what part of the brain?
Occipital lobe
100
Seizures are a symptom of this disease and it can affect just a part of the brain or be generalized over the whole area of the brain.
Epilepsy
100
What is the part of the nervous system that is made up of the brain and spinal cord?
Central Nervous System
200
The branches off of the cell body that receive the stimulus from other neurons are called?
Dendrites
200
What is happening during depolarization?
Sodium (Na+) channels open causing Na+ to rush into the cell and change the inside of the cell from a negative charge to a positive charge.
200
Balance and muscle coordination is controlled by what part of the brain?
Cerebellum
200
This disease is caused by proteins sticking together in the brain, disrupting communication between the neurons. Symptoms including confusion, forgetfulness, and difficulty thinking and worsens over time.
Alzheimer's Disease
200
How many sodium (Na+) are moved out and how many potassium (K+) ions are moved in through the sodium-potassium pump at a time?
3 Na+ and 2 K+
300
The fatty, protective covering over the axon of the neuron that also helps speed up the action potential is called?
Myelin sheath
300
What happens during repolarization?
Sodium (Na+) channels close and potassium (K+) channels open, causing K+ to rush out of the cell. This restores the negative charge on the inside but it goes too negative.
300
What does the temporal lobe control?
Hearing
300
This disease is a result of the breakdown of the myelin sheath around the axon, slowing down the conduction of nerve impulses. This results in pins and needles feeling, balance problems, trouble walking, and depression and fatigue.
Multiple Sclerosis
300
This disease is a genetic disease that can be passed down through the generations and causes a particular protein to clump in multiple areas of the brain and cause a variety of symptoms including mood swings, clumsiness, easy bruising, and involuntary movement.
Huntington's Disease
400
What are the functions of all three types of neurons? (MUST GET ALL 3 TO GET THE POINTS)
Sensory neuron --> Sends external stimuli message to CNS, Association neuron --> Connects sensory to motor neurons, Motor neurons --> Sends message from CNS to effector organs
400
What is occurring during hyperpolarization?
The sodium-potassium pump is restoring resting potential by moving 3 Na+ out of the cell for every 2 K+ moved in.
400
What does Broca's area control?
Speech production
400
In this disease, the motor neurons die causing severe deterioration of muscle control for movement and breathing but cognitive abilities remain intact. This is a terminal disease and worsens over time.
ALS
400
Language understanding is processed in what area of the brain?
Wernicke's area
500
Put the following terms in the correct order for the pathway a message takes through a neuron. (Axon, Cell body, Dendrites, Axon terminals)
Dendrites --> Cell body --> Axon --> Axon Terminals
500
Draw a graph of an action potential and label the following parts on it. (Hyperpolarization, Threshold, Resting Potential, Repolarization, Depolarization)
Look on Board
500
Thirst and hunger are controlled by what part of the brain?
Hypothalamus
500
This disease is due to a loss of dopamine causing loss of movement (tremors, small handwriting, loss of balance) and abnormal emotional responses.
Parkinson's disease
500
Write out what happens from the time of hearing the bell ring at the end of class (stimulus) to walking to the hallway (response)
