Enlarged Artery & Vein Model — MYASKRO

Anatomic Details

• Giant longitudinal cross-sections of a muscular artery and a medium vein.

• Demonstrates tunica intima (endothelium, subendothelial layer, internal elastic lamina), tunica media (circular smooth muscle; external elastic lamina in artery), and tunica adventitia (collagen, vasa vasorum, nervi vasorum).

• Vein segment with bicusp venous valves (leaflets, sinus, commissures).

• Central block showing arteriole → capillary plexus → venule (microcirculation).

• Surrounding adipose tissue and peri-vascular connective tissue.

Learning objectives

• Differentiate artery vs vein wall architecture and lumen morphology; explain pulsatile conduit (artery) vs capacitance vessel (vein).

• Trace flow through arterioles–capillaries–venules and relate to diffusion/exchange.

• Correlate structure with common pathology: atherosclerosis/intimal plaque, aneurysm (media weakening), varicose veins/valvular incompetence, DVT sites, phlebitis.

• Use for OSCE/viva: identify layers, elastic laminae, venous valve components, and vasa vasorum.

Specifications

• Approx. 27 × 20 × 24.5 cm on a stable base (classroom display size).

• Material: Medical Grade PVC.

• Cleaning: mild detergent or 70% alcohol wipes; avoid solvents/heat.

• Intended use: instructional model for physiology, pathology, cardiology, nursing, and patient education.
