Is this an intact anatomically correct human hand or is it a manipulated image?
It is from a famous historical photo, but I am just asking about the anatomy of this hand. Based on what you know about the anatomy of the human hand, does it look like a complete, natural normal hand to you or not?
Chapter 6 SLA: 1. When I open my hand, the palmar surface of my hand is white. When I release pressure from my thumb my hand becomes red. The closest part of my hand turned red first and then the top turned red also. The ulnar artery was closed off. When I released the pressure from my index my fingers turned back red. The bottom of my fingers changed first and then

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

At the presynaptic terminal, the arrival of impulse at the synaptic knobs and prior to the release of neurotransmitter is associated with the influx of which one of the following ions into the presynaptic terminal.
Patient Case A 50-year old woman presents to the emergency room with a 24-hour history of abdominal pain that began approximately one hour after a reportedly large dinner. The pain began as a dull ache in the epigastrium but then localized in the right upper quadrant. She reports some nausea but no vomiting. Since her arrival to the ER, the pain has decr

Evaluate and distinguish between the anatomical and functional divisions of the nervous system. Devise a detailed description of the structure and functions of each organelle in a typical neuron. Distinguish the locations and functions of the four neuroglial cells in CNS and the two neuroglial cells in PNS. Categorize the structure of the spinal cord to its function.
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(

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
