Induction of a Subarachnoid Hemorrhage in a Mouse Model through Endovascular Perforation
0 Views •
2025
The video demonstrates the induction of subarachnoid hemorrhage via endovascular perforation in a mouse model. An incision is made in the neck region of the anesthetized mouse to access the common carotid artery and its bifurcation. A filament is inserted through the arteries to perforate an intracranial artery branch, inducing subarachnoid hemorrhage.

Esophageal Perforation-I: Introduction
0 Views •
2025
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks. The location of esophageal perforation can vary, occurring anywhere along the esophagus.

2025
This video demonstrates electrophysiological recording of olfactory sensory neurons (OSNs) in mice using a perforated patch-clamp technique. The olfactory epithelium, containing OSNs with fluorophore-tagged odor receptors, is isolated from a mouse and secured in a recording chamber. A recording pipette is clamped to the dendritic knob of an OSN, and nystatin within the pipette perforates the membrane to form electrical connectivity with the cell. Finally, another pipette is used to deliver an...

Source: Alexander S Rattner and Kevin Rao Li Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA The objective of this experiment is to demonstrate the phenomenon of stability of floating vessels - the ability to self-right when rolled over to the side by some external force. Careful design of hull shapes and internal mass distribution enables seagoing vessels to be stable with low drafts (submerged depth of hull), improving vessel...

2025
This video demonstrates the patch-clamp technique for measuring ionic currents in inner ear sensory neuron cell bodies. It details the preparation and use of a polished patch-clamp pipette filled with an internal solution containing amphotericin B, which perforates the membrane to allow ion movement while preserving intracellular conditions. Voltage pulses are applied to trigger and record ion channel activity, providing insights into their properties and behavior.
FAQs
Their functional importance comes from maintaining vascular continuity across anatomical boundaries. A vessel can leave a parent vascular network, follow a defined route through fascia, muscle, or bone, and reach a neighboring tissue layer. This arrangement links deeper and more superficial structures, allowing oxygenated blood to reach tissues or enabling venous drainage from regions that would otherwise belong to separate vascular layers.
Perforating arteries and veins support circulation in opposite directions. Arteries deliver oxygenated blood from a parent vascular network toward deeper tissues or adjacent regions, whereas veins drain blood away from those areas. Examining both types together gives a more complete picture of regional circulation and helps explain how tissue layers remain connected through an anatomical boundary.
These features help explain how effectively a region receives or drains blood. Vessel location indicates which tissue layers and adjacent structures are connected, while branching patterns show how circulation is distributed within the region. Differences in size may also reflect the relative importance of particular pathways, making these anatomical characteristics relevant to tissue viability and regional vascular assessment.
Mapping can document the location, size, pathways, and branching patterns of these vessels in relation to fascia, muscle, bone, and neighboring structures. This information clarifies regional circulation and identifies connections between tissue layers. In biology and medicine, the resulting anatomical knowledge supports interpretation of vascular organization and provides a foundation for planning procedures that must preserve blood supply.
Their defined pathways and relationships with anatomical boundaries provide a framework for recognizing vascular structures on imaging. Understanding where vessels pass between tissue layers can help distinguish regional connections and clarify the blood supply or drainage of deeper tissues. This makes perforating vessel anatomy useful when imaging findings must be related to surgical planning or tissue viability.
Surgical planning considers these vessels because disrupting an important pathway may affect blood delivery or drainage in connected tissues. Mapping their locations and routes helps relate the intended operative area to nearby vascular structures. That anatomical information supports plans designed to preserve circulation, particularly when surgery involves tissue layers connected across fascia, muscle, bone, or adjacent regions.
In reconstructive procedures, knowledge of perforating vessels helps surgeons plan tissue transfer while preserving the vascular connections that sustain the transferred tissue. Their mapped size, location, and branching patterns indicate how a tissue region relates to its parent vascular network. This supports selection and handling of tissue in ways intended to maintain blood supply and improve tissue viability.
