Mariel was in a car accident and suffered damage to her reticular formation. Which of the following is she most likely experiencing?
A. Convulsive Seizures
B. A Coma
C. Inability to Make New Memories
D. Change in her Personality

too little of this chemical can lead to Alzheimer's disease
acetycholine
part of brain linked to emotion; specifically anger and fear
the amyglada
Describe the difference between beta waves, alpha waves, and theta waves

After suffering a stroke, Manny lost his ability to comprehend language. It is most likely that Manny suffered damage to
A. His right temporal lobe
B. His hippocampus
C. Wernicke’s Area
D. Broca’s Area
C: Wernicke's area, located in the left temporal lobe, is responsible for language comprehension.
chemical involved in motor messages and behavior; if a person has too little of this chemical, they may suffer from Parkinson's disease, too much leads to schizophrenia
dopamine
the lobe of the brain with executive functions such as making decisions, planning, reasoning, and carrying out actions.
the frontal lobe
part of the endocrine system that secretes epinephrine and norepinephrine
adrenal glands
The somatosensory cortex is to the ______ lobe as the motor cortex is to the _______lobe.
A. Parietal; frontal
B. Occipital; frontal
C. Frontal; temporal
D. Parietal; temporal
A: The somatosensory cortex is located in the parietal lobe; the motor cortex is located in the frontal lobe
stored in sacs in the axon terminal; chemical messages that cross over to the next nerve cell
neurotransmitters
hemisphere of the brain that controls spatial behavior and artistic efforts
the right hemisphere
sleep disorder which causes a person to fall asleep at unpredictable intervals; this condition is very rare and dangerous
narcolepsy
Juan was bit by a black widow spider. The venom is an agonist for ACh. What is Juan likely to be experiencing?
A. Paralysis
B. Migraine Headaches
C. Insomnia
D. Muscle spasms
D: ACh, or acetylcholine, is one of the best-understood neurotransmitters and can be found at every junction between motor neurons and skeletal muscles. It enables muscle movement, and also plays a role in learning and memory. An antagonist is a molecule that enhances a neurotransmitter's action. The spider venom enhanced Jaun's muscle actions, resulting in spasms
Describe the parts of a neuron
i'll judge the answer
the structure of the brain that connects and relays messages between the two hemispheres; severed in extreme cases of epilepsy
the corpus callosum
What can be expected in someone who has been a long-term user of the drug Ecstasy?
A. An increased production of dopamine, resulting in hallucinations
B. Damaged serotonin-producing neurons, leading to depression
C. Reduced dopamine levels, resulting in depression
D. Decreased production of endorphins, leading to lower pain thresholds
B: Ecstasy, also known as MDMA or "Molly," is a stimulant and mild hallucinogen. It triggers dopamine release and blocks the reuptake of serotonin resulting in a feel-good rush of emotions and a feeling of connection with those around you. In addition to the damage to serotonin-producing neurons, Ecstasy also suppresses the nervous system, impairs memory and can disturb the sleep cycle.
Your ability to swat at a fly buzzing around your head is due to your
A. Somatic nervous system
B. Autonomic nervous system
C. Parasympathetic nervous system
D. Endocrine system
A: The somatic nervous system is part of the peripheral nervous system. It is responsible for gathering information and directing central nervous system decisions to your body parts.
