-First - faster - not
-Second - slower - often
This week, the red blood cell travels past a pair of neurons. While passing them, the RBC notices that the postganglionic neuron's axon is longer than the preganglionic neuron's axon. Therefore, the RBS correctly stated that this neuron pair is a part of the _____ nervous system within the _____ nervous system.
- Sympathetic - peripheral
- Sympathetic - autonomic
- Autonomic - Efferent
Bats utilize their hearing of sounds to move through the environment. Humans are typically unable to hear these sounds. Consequently, you correctly understand that bats and humans both have matching _____ and bats have a greater _____.
Modality - Adequacy
Dr. Gray's Patient Y was born with all of his preganglionc axons being of identical length. Consequently, Dr. Gray knows that Patient Y has sympathetic preganglionc neurons _____ activating parasympathetic postganglionic neurons.
Sometimes
Which is a correct statement about the parasympathetic nervous system?
-When activated, its preganglionic neurons always release acetylcholine
-When activated, its postganglionic neurons sometimes release epinephrine
-It is also know as the "rest and regroup" response
-There is always two neurons available
Which of the following are both brain parts comprised of just two components?
- Cerebrum - Diencephalon
Brutus Buckeye was visiting another mascot who has recently had a stroke. He noticed that his friend was experiencing difficulties with speaking and remembering their last game together. Consequently, Brutus correctly realized that the stroke likely occurred in the...
-Cerebral cortex
-Forebrain
-Cerebrum
Which is a correct statement about neurotransmitters?
-In lecture, we learned about an individual one and then three groups of them
-Some amino acids can cause hyperpolarizations in the the postsynaptic cell
-The most common neurotransmitters impacts mood
-Neuropeptides are sometimes found in the smallest fluid compartment
Which is a correct statement about the brain?
-The thalamus acts as a relay station for crude sensation
-The pons is part of the oldest portion of the brain
-Like in the spinal cord, the gray matter of the cerebral cortex contains interneurons' cell bodies
-The vast majority of the weight of the brain is within the forebrain
While hiking downstate in the Hocking Hills, Phys Phab Nick encounters a mother bear and her two cubs. Consequently, nick correctly realizes that...
-Epinephrine will now be present in all three of his fluid compartments
-His adrenal medulla will be releasing norepinephrine into his plasma
-Acetylcholine will be getting released only by his preganglionic neurons with short axons
Which is a correct statement about a toxin that causes a decrease in the coding of intensity?-It could cause a decrease in action potential frequency -It could decrease the amount of time that the voltage-gated calcium channels are open in the axon terminalWhich is a correct statement about the autonomic nervous system?-When activated, acetylcholine is sometimes released by its postganglionic neurons -Its ganglia are clusters of cell bodies located in the peripheral nervous system areaDr. Yul B Allwright was drinking a cup of hot coffee and accidentally spilled it on his leg causing a painful burn. While cleaning himself up, Dr. A correctly realized that...-Thermoreceptors were not responsible for the sensation of the burn -The burn sensation is associated with the top half of our reflex templateA pheochromocytoma is a tumor that causes the adrenal gland to secrete too may endocrines. You correctly determine that an individual with this type of tumor will have...-Increased plasma levels of certain biogenic amines -Both pupil and bronchiole dilationDr. Scarlet's Patient X suffered a head injury in a car accident. Patient X is having trouble walking in a coordinated manner and difficulty forming complete sentences. Dr. Scarlet correctly realizes that...-There is likely damage to the cerebellum and the cerebrum -A component of the forebrain was impacted
