How many pairs of cranial nerves are there in the PNS?
In Expiration: pleural pressure and intrapulmonary pressure increase or decrease
Expiration: increase or decreaseThoracic cavity volume Alveolar pressure
Inspiration: increase or decreaseThoracic cavity volume Alveolar pressure
Gases will move from a region of ... pressure to a region of ... pressure (similar to movement via concentration gradient)
In inspiration: pleural pressure becomes more ... and ... than pressure inside the lungs causing lungs to expand
What is the intrapleural pressure value
decreases the amount of positive on the inside (becomes negative again, potassium is leaving)
myelinated nerve (axons and dendrites) sending out signals
Reticular Activating System. Allows us to have sleep wake cycle and maintain consciousness.
Sensory information goes straight to the spinal chord and synapses right on the motor neuron to relax. Sensory going in and motor coming out, only one synapse occurs. Some reflexes have an interneuron.
jumping down the axon from one node to another (from mylenation)
contains midbrain, pons, and medulla. Involved in autonomic functions
occipital lobe, frontal lobe, parietal lobe, hypothalamus, thalamus, cerabellum, brain stem, cerebral cortex, basal nuclei, pineal gland
increase the amount of positive on the inside (more positive, sodium is going in)
you become tolerant to a substance and need more to get the same effect
the hippocampus is both. short term = prefrontal cortex in the frontal lobe. long term and short term = hippocampus
what happens when you stop using a substance that you become addicted to
5.) Voltage gated Na+ channels open on axomembrane & not move in (depolarization)
