The trabeculae carneae and the papillary muscles make up a significant percentage of the ventricular mass in the heart (12-17% in normal human adult hearts), and are correlated with ventricular end diastolic volume. [5] Trabeculae ratios of capillary-to myocyte differ between the walls of the right and left ventricle.

The moderator band (also known as septomarginal trabecula [1]) is a band of cardiac muscle found in the right ventricle of the heart. [2] [3] [4] It is well-marked in sheep and some other animals, including humans. It extends from the base of the anterior papillary muscle of the tricuspid valve to the ventricular septum. [2]
The massive ventricle can lead to a heart weighing over 1000 grams (the weight of a normal heart is about 350 grams), referred to as cor bovinum (Latin for cow's heart). [1] Fluri and Gebbers [2] define cor bovinum as a heart exceeding 500 g in weight. Looking through autopsies on Internal Medicine patients at the Kantonsspital Luzern, they ...
Tissue heart valves are usually made from animal tissue (heterografts) mounted on a metal or polymer support. [14] Bovine (cow) tissue is most commonly used, but some are made from porcine (pig) tissue. [15] The tissue is treated to prevent rejection and calcification (where calcium builds up on the replacement valve and stops it working ...
The chordae tendineae (sg.: chorda tendinea) or tendinous cords, colloquially known as the heart strings, are inelastic cords of fibrous connective tissue that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
Pithing / ˈ p ɪ θ ɪ ŋ / is a technique used to immobilize or kill an animal by inserting a needle or metal rod into its brain.. It is regarded [by whom?] as a humane means of immobilizing small animals being observed in experiments, and while once common in commercial slaughtering is no longer practiced in some developed countries on animals intended for the human food supply due to the ...
Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is an incurable and invariably fatal neurodegenerative disease of cattle. [2] Symptoms include abnormal behavior, trouble walking, and weight loss. [1]
