Nervous System & Brain
The _ system is responsible for voluntary functions.
Somatic Nervous System
The thalamus processes all sensory information except _
smell
The _ surrounds axon with a layer of insulation to speed up information transfer down the axon.
Myelin Sheath
Acetylcholine, dopamine, serotonin, and GABA are all examples of _.
Neurotransmitters
_ is the process of forming/synthesizing new neurons.
Neurogenesis
Sensory neurons bring information...
inside to the spinal cord
The _ regulates body temp, hunger, thirst, sexual behaviors, sleep
Hypothalamus
The _ cortex is involved in processing visual input, while the _ cortex is involved in integrating sensory information with your memories.
(primary) Visual Cortex
Association cortex
What occurs after the action potential, that does not allow for additional firing of electrical signals?
Refractory period
What helps release hormones and is known as the master gland?
Pituitary Gland
The primary responsibility of the Medulla is
Basic life functioning (breathing, heart rate, sneezing)
The _ is the auditory cortex, the _ is the visual cortex, and the _ processes body sensations through the somatosensory cortex.
Temporal Lobe
Occipital Lobe
Parietal Lobe
Which portion of the neuron contains structures that synthesize proteins and produce energy?
Cell body or soma
If a signal causes the internal charge of the neuron to increase/decrease, it is an example of _ .
Postsynaptic potential
_ binds to the same receptor as the neurotransmitter and can cause the same effect as neurotransmitters.
Agonists
James was injured a few months ago and now struggles with fine motor movements like writing. This is due to the _ cortex.
Motor cortex
The _ involves using a type of memory that allows you to do mental math or remember a phone number.
Prefrontal Cortex
These techniques allow researchers/clinicians study the brain of healthy, awake people.
Neuroimaging
OR
PET, fMRI, MRI, CT
_ causes slow-developing changes in activity as they travel a longer distance to transfer a message.
Hormones
_ allow ions to pass through the cell membrane, while _ releases chemicals into the synapse.
Ion channels
Vesicles
Kristy is a heavy alcohol drinker and often falls over or trips over her feet when trying to stand. What area of the brain is being affected?
Cerebellum
_ is associated with damage to the hippocampus, while _ is associated with damage to Broca’s area or Wernicke’s area.
Amnesia
Aphasia
Alexa was in a car crash and experienced brain injury. Ever since this wreck, she often goes on late night walks, never checking her surroundings and gets lost when walking back home. This is due to damage in the _ system.
Limbic System
Jake has been experiencing panic attacks and flashbacks due to frequently using _.
Hallucinogens
If there are connections within the nervous system that are not being used, _ occurs to improve the transfer of information throughout the nervous system.
Synaptic Pruning
