It took the diagnosis of high blood pressure (hypertension) at the age of 45 to shock Max into taking better care of himself. A former college football player, he had let himself go, eating too much junk food, drinking too much alcohol, sitting on his chubby bottom for the majority of the last two decades, and even indulging in the frequent habit of smoking cigars. Max’s physician h

A gastrocnemius muscle at optimal length, when maximally stimulated by a single electrical stimulus, produces an isometric twitch tension of 80kg, and consumes 5 joules of energy above its basal energy consumption (measured by a calorimeter—includes all the energy used by the muscle as a result of that stimulus).If you then stretch the muscle (hyper-extend it) so that the same maxim
After a serious automobile accident, a man suffers from emotional instability, poor appetite, and alternating chills and fever. His memory and muscle control seem normal. As students in a medical school, you and your peers must diagnose his illness. One student suggests that the patient has a hormonal imbalance due to a damaged gland. Another argues that the
Assume I have a membrane of volume V, and potential Vm across it.Inside, there's some concentration of sodium Cna(in), chloride Ccl(in) and neutral macromolecule b (Cb).
Also, the sodium is being actively transported from the inside to the outside with Jna_a the active current density (constant). The outside has also some concentration of sodium Cna(
Activity 2 - Twitch Contractions and Summation [PowerPhys]
I got 100% on this but it took a while to do this report. I hope it helps those that want to understand better this type of contractions. Think before copying it. The best way to learn something is to understand it and make it meaningful. Have a great day!!
Part I – Sub-Saharan Safari A 51-year-old man named Robert Bragg reported to a hospital in the United Kingdom complaining of general malaise (discomfort), myalgia (muscle pain), fevers, headache, vomiting, and diarrhea. He complained that during the day he felt weak and tired; he was unsure if this was because his symptoms kept him awake at night, or if something el

Alex has eaten a mysterious berry which seems to have affected his fat digestion and absorption. He goes in to see a doctor for further analysis and is told that as the fat droplets enter into the small intestine they are being emulsified. The doctor also tells him that the enterocyte border is healthy and intact, and that his cellular function is normal. What aspect of fat digestio
Alkalosis and Potassium Secretion, What is the mechanism of events?
Hello everyone. I've been trying to understand the action of principal cells in the kidney collecting ducts in alkalosis. My professor told me that the activity of proton-potassium pumps in the basolateral membrane lead to high potassium concentrations in the principal cell and therefore lead to higher potassium secretion to the lumen. The confusing thing is, if the plasma has

1. Compare and contrast chemically gated and voltage gated ion channels in skeletal muscle fibers versus in neurons. Include in your discussion the variety of chemically gated ion channels and all types of voltage gated individually (Na+,K+, and Ca++). Also discuss how the distribution of voltage gated channels change in myelinated versus unmyelinated axons.
A 19 year old man is admitted to the emergency room with a stab wound to the lateral aspect of his left thorax along the midaxillary line (i.e. along the coronal plane through the mid-thorax). Palpation reveals that the puncture passes through the sixth intercostal space. It is obvious that the blade has punctured the lung, causing a pneumothorax. Part A. Moving from superfici
