| Question | Answer |
|---|---|
| The membrane potential of a neuron that is conducting an impulse; also known as a nerve impulse | action potential |
| What is the function of acetylcholine in the parasympathetic division? | It slows the heartbeat and promoters elimination and digestion |
| Describe receptor potential | Receptor potential is when sufficient stimulus reaches past a threshold and an action potential gets triggered in the sensory neuron's axon where impulses travel to the brain via sensory pathways for reflex action or a specific sensation |
| Which hormone stimulates gluconeogenesis in liver cells, produced by alpha cells, and increases blood glucose levels | Glucagon |
| What heart sound is a sharp and short and is caused by the SL valves closing | Diastolic sound |
| How does contractions of skeletal muscle affect venous return? | It does so by squeezing veins whenever the skeletal muscle contracts by pushing it towards the heart |
| How does the lymph nodes perform filtration? | The lymph nodes do biological filtration by removal/destroying of particles and mechanical filtration by stopping particles physically |
| True or False, immunization is considered artificial acquired passive immunity? | True |
| The sum of all four lung volumes and the total amount of air the lungs can hold | Total Lung Capacity (TLC) |
| What are the mechanisms used in the digestive system? | Ingestion, Digestion, Motility of the GI wall, Secretion, Absorption, Elimination, Regulation |
