Which layer of the heart consists of endothelial cells? Epicardium Myoc Which of the following statements regarding the heart is NOT true? A) The heart has four chambers. B) The heart is located in the mediastinum of the chest....
The heart wall consists of an inner membrane, or endocardium, a middle layer, or myocardium, and an outer layer, or epi-cardium. The endocardium lines the chambers of the heart and is composed of connective tissue containing collagenous, elastic, and smooth muscle fibers, blood vessels, and ...
A body tissue composed of elongated cells (called muscle fibers) that contract to produce movement. In vertebrate animals, voluntary movement is produced by the action of muscles on bone. Movement of the muscles of the heart and other organs is involuntary and controlled by the autonomic nervous...
Myocardium(myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart. The myocardium of the left ventricle is...
Muscles are made of soft tissue and numerous stretchy fibers. Some help you perform small, delicate tasks braiding hair, and others are used for more strenuous activities like running. Muscles also aid digestion and breathing. The heart is an amazingly strong muscle that beats thousands of times...
Answer to: Choose the correct answer: The normal pacemaker of the heart is the A) bundle of His B) Purkinje fibers C) atrioventricular node D)...
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
Moreover, we find that I/R-induced upregulation, cleavage and nuclear accumulation of Tisp40 in the heart are mediated by endoplasmic reticulum stress. Our findings identify Tisp40 as a cardiomyocyte-enriched UPR-associated transcription factor, and targeting Tisp40 may develop effective approaches ...
The heterogeneity of functional cardiomyocytes arises during heart development, which is essential to the complex and highly coordinated cardiac physiological function. Yet the biological and physiological identities and the origin of the specialized cardiomyocyte populations have not been fully comprehended. ...
