Q&A
Which hormone is released when a person is under stress?
-Cortisol. Testosterone. Progesterone. Oxytocin.
The hormone most associated with the fight or flight response is
Epinephrine. Oxytocin. Serotonin. Glutamate. Dopamine
Epinephrine.
A neuron sends a signal along its
axon. dendrite. synapse gap. meylin sheath. Neurotransmitter.
AXON
central nervous system is made up of what two body parts?
Brain and Spinal cord
involved in memory formation and learning
activates skeletal muscles and carries out voluntary movements
The medulla oblongata is a part of the
Cerebellum. Brainstem. Prefrontal cortex. Corpus collosum.
Carl Wernicke discovered the region of the brain that is responsible for
visual perception/ sense of balance/ language production/ language comprehension
A person whose body is not producing enough testosterone is most likely to exhibit
Fatigue. Memory Loss. Increased Hunger. Overly Aggressive behavior/
Fatigue
Afferent(sensory) Neurons
BODY-----> SPINAL CORD ------> BRAIN
Glutamate VS GABA
glutamate is an EXCITATORY(encourages neurons fire) NEUROTRANSMITTER
GABA is an INHIBITORY (slows down) NEUROTRANSMITTER
What effect do agonists have?
- They increase the likelihood that a postsynaptic neuron will fire.
-They decrease the likelihood that a person will get a good night’s sleep.
-They decrease the likelihood that a postsynaptic neuron will fire.
-They stimulate the gastric system, leading to increased hunger.
They increase the likelihood that a postsynaptic neuron will fire.
Waking up frequently, loud snoring, silent pauses in breathing, and sleepiness during the day are symptoms of
sleep apnea
The fatty casing that helps speed up the neural transmissions of a neuron is called the
myelin sheath
this part of the brain sits behind the top portion of the brainstem.
involved in fine motor control, coordination, posture, and balance. Helps with learning and remembering skills
the CEREBELLUM
A system of brain structures and neural networks involved in processing emotion and long term memory
THE LIMBIC SYSTEM
The psychodynamic theory of dreaming would postulate that
dreams fulfill unconscious wishes
The idea that there is a part of the mind that is not directly accessible to awareness but still drives a person’s thinking and behavior is most directly attributable to
sigmund freud
The parietal lobe is most involved in
processing sensory information
WERNICKE'S AREA AND WERNICKE'S APHASIA
Wernicke's area: involved in the comprehension and understanding of written and spoken language.
Wernicke's aphasia: Difficulty expressing and understanding written and spoken words/sentences.
lateral vs ventromedial HYPOTHALAMUS
LH: regulates feelings of hunger
VH: regulates feelings of fullness
The phenomenon of declining physiological effects of taking a drug after sustained use is referred to as
tolerance
Which of the following best describes a major role of the thalamus?
It relays most sensory signals to the cortex.
Michael Gazzaniga is best known for
studying split-brain patients
what happens if someone's amygdala is damaged?
It can cause people to lose their sense of fear, aggression or make them very passive.
what happens us someone experiences Broca's Aphasia?
They will have difficulty producing speech. Sentences will be simple, usually only containing a noun and verb.
ex: walk dog. --> i will take the dog on a walk
