NS Quiz 1

QuestionAnswer
Nucleus, cortex- sheet, lamina-layer, column CNS gray matter, neuronal cell bodies
Tract, fasciculus, lemniscus, capsule, peduncle, commisure CNS white matter, axons
Ganglion PNS, neuronal cell bodie ie. cranial nerve ganglion, posterior root ganglion
Peripheral nerves, rami, roots Nerve Fibers, PNS ie. cranial nerves
Cerebrum or brain houses the.. hemispheres, diencephalon
Brainstem and the Cerebellum houses the.. midbrain, pons, medulla, cerebellum
Frontal lobe fx Motor, executive functions, language
Parietal lobe fx Sensory, cognition.language processing
Temporal lobe fx hearing, language, learning and memory
Occipital Lobe fx Vision
Left Brain vs. Right Brain Left- logic, right-creative
Diencephalon houses the: what are its features Thalamas: collections of nuclei ant: motor relay post: sensory relay Hypothalamus: hormones, homeostatis, visceral activity
All nerve fibers that arise from one spinal cord segment innervate how many dermatomes 1
Pseudounipolar somatic, visceral Cell bodies part of PNS (one exception)
Bipolar olfactory, visual, auditory, vestibular PNS cell bodies
Multipolar Somatic/automatic, interneurons, cell bodies part of CNS or PNS
depolarizing, hyperpolarizing de-more positive, hyperpolorazing-more negative
Absolute refractory period Relative refractory period A: AP cannot be generated Na channels inactivated R: AP can be generated but stumuls threshold increased
Local potential Action Potential Less over time, graded response: amplitude and duraction is proportional to stimulus intensity, excitory and inhibitory A: all or nothing, requires threshold stimulus, always excitory
plasticity modification of a synapse, normal for them to go away over time, modifications throughout life short term vs. long term
habituation decrease in response to a repeated, benign stimulus, can happen short term/long term new ring tone in environment: new distracting, always happens not as distracting
PNS glia and CNS glia PNS: Schwann cells CNS: astrocytes, oligodendrocytes, microglia
Schwann fx myelinate PNS axon, surround unmyelinated axons
Astrocytes fx guide neuronal migration during development, response to injury, trophic support for neurons
oligodendrocytes fx myelinate CNS
microglia fx: sense changes in environment, change morphology in response to injury

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
