2023年1月2日 · At the histological level, the cellular features of the heart play a vital role in its normal function and adaptations. The heart is a four-chambered organ responsible for pumping blood throughout the body.
Cardiovascular System | histology - University of Michigan
Recognize the major structural features of the heart (such as cardiac muscle, valves, cardiac fibrous skeleton) and know their functions. Be able to describe the path of the cardiac impulse from sinoatrial node to the ventricle and recognize the cells (Purkinje fibers) in the ventricle that are involved and be able to identify them.
Cardiovascular System | Histology Guide
HEART. The heart is a pump that contracts rhythmically sending blood through the cardiovascular system. The contractile wall of the heart, the myocardium, is composed of cardiac muscle cells.
Cardiovascular System - Heart Histology - Embryology
6 天之前 · Cardiac muscle is innervated by the autonomic nervous system (involuntary), which adjusts the force generated by the muscle cells and the frequency of the heart beat. Cardiac muscle cells often branch at acute angles and are connected to each other by specialisations of the cell membrane in the region of the intercalated discs.
Histology of the cardiovascular system - Kenhub
2024年1月17日 · General histological features of arteries and veins. The cardiovascular system is a network composed of the heart as a centralized pump, blood vessels that distribute blood throughout the body, and the blood itself, for transportation of different substances.
Cardiac muscle tissue histology - Kenhub
2022年11月23日 · Cardiac muscle tissue, also known as myocardium, is a structurally and functionally unique subtype of muscle tissue located in the heart, that actually has characteristics from both skeletal and muscle tissues. It is capable of strong, continuous, and rhythmic contractions that are automatically generated.
Heart 1 - Digital Histology
The cardiac skeleton is composed primarily of dense connective tissue, providing a framework for the attachment of cardiac muscle fibers, support for heart valves and electrical insulation between the atria and ventricles.
