The abdominal dorsal vessel of the honey bee and other insects serves as the functional equivalent of the mammalian heart and plays an important role in nutrient transport, waste removal, immune function, and more. Here we describe a protocol for the visualization and pharmacological manipulation of bee heart rate.

This video demonstrates the isolation of intact vessels from a mouse's brain that constitute the blood-brain barrier (BBB) along with neurons and glial cells. The isolated vessels can be used as an in vitro model to study their role in maintaining brain homeostasis.

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...

A procedure for making en face preparations of the mouse carotid artery and aorta is described. Such preparations, when immunofluorescently stained with specific antibodies, enable us to study localization of proteins and identification of cell types within the entire vascular wall by confocal microscopy.
FAQs
Once blood enters the vessel wall, pressure drives it along the space between wall layers rather than through the normal channel alone. This creates a false passage whose expansion can compress the true lumen, reducing the route available for blood flow. The central mechanical concern is therefore altered circulation, not merely the initial wall injury.
The false passage can narrow the true lumen and restrict blood movement, creating a risk of ischemia in tissues supplied downstream. At the same time, blood tracking within the wall can weaken the vessel’s structure, promoting aneurysm formation or rupture. These separate effects explain why vessel dissection can produce both circulatory and structural complications.
Pressurized blood is the force that allows the abnormal passage to extend between vessel-wall layers. As blood continues to track through that space, it can increase compression of the true lumen or further stress the wall. Understanding this mechanical process helps explain how an initially localized injury may become clinically important through impaired circulation or progressive weakening.
Medical evaluation connects acute vascular symptoms with imaging findings that show how the vessel has been affected. Clinicians use this combined information to consider whether circulation is being compromised and whether the vessel wall has become structurally vulnerable. The assessment therefore supports both interpretation of the condition and selection of an appropriate treatment strategy.
Imaging interpretation helps characterize the relationship between the abnormal passage, the vessel wall, and the true lumen. This information can indicate whether normal blood flow is being narrowed and whether complications such as aneurysm formation or rupture are relevant concerns. Accurate interpretation supports clinical decision-making beyond evaluating symptoms alone.
Recognizing the dissection clarifies the mechanisms that may be threatening the patient, including impaired circulation, ischemia, aneurysm formation, or rupture. That information gives clinicians a basis for choosing among treatment strategies suited to the vascular problem identified. In this way, diagnosis connects the pathological process with decisions intended to prevent further complications.
