On hot summer days, Devon relies on what brain structure to monitor his thirst and the need to drink more water?
HYPOTHALAMUS
Place in order the events that occur when a neuron fires.
1.Dendrites receive chemical signals. 2.When more excitatory than inhibitory signals are received, the cell depolarizes. 3.An action potential is set off and travels through the cell and down the axon. 4.The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.
Match each brain structure with its related task.

Fill in the blanks to complete the passage about multiple sclerosis.
Multiple sclerosis (MS) is a disorder of the NERVOUS system, characterized by deterioration of the MYELIN SHEATH AROUND AXONS. Initial symptoms often include numbness in the limbs and BLURRED VISION. As the disease progresses, it slows down the body's internal communications and causes motor movements to become jerky and poorly coordinated.
Match the neurotransmitter with the person's experience.
Parkinson's disease ►Low levels of dopamine Sadness, anxiety, aggression ►Low levels of serotonin Energy burst ►High levels of epinephrine Euphoria and insensitivity to pain ►High levels of endorphins Epileptic seizures ►Low levels of GABA
Broca linked a loss of function in his patients to lesioned areas in the left hemisphere of their brains. What is the function of Broca's area?

Match each event with the action that follows it.
The cell hyperpolarizes. ►Neuron receives inhibitory chemicals. The cell returns to resting potential. ►Sodium and potassium gates close. Sodium ions rush into the cell. ►Sodium gates open. Potassium ions rush out of the cell. ►Potassium gates open. The cell depolarizes. ►Neuron receives excitatory chemicals.
