This is achieved through a process known …
WebFeb 1, 1998 · Decreased myocyte function, the topic of this review article, may be due to alterations in calcium handling, reduced myofilament function, alterations in the myocyte cytoskeleton, or a combination of these factors. The precise mechanism of myocyte dysfunction in CHF remains largely unknown, however. WebSep 1, 2005 · The primary function of the heart is to pump blood efficiently by virtue of an orchestrated contraction–relaxation cycle of the working myocytes. Regulation of contractility of the individual cardiomyocytes is achieved by a spatially defined program of ion channels and exchangers that accurately control Ca 2+ entry into and out of the cell ...
WebNov 23, 2024 · Secondly, they allow cardiac muscle tissue to function as a functional syncytium. Essentially, the contractile stimuli is propagated from one cell to the next one, resulting in a synchronous contraction of the … To activate a muscle, the brain sends an impulse down a nerve. The nerve impulse travels down the nerve cells to the neuromuscular junction, where a nerve cell meets a muscle cell. The impulse is transferred to the nerve cell and travels down specialized canals in the sarcolemma to reach the transverse tubules. The … See more A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell. While … See more As seen in the image below, a muscle cell is a compact bundle of many myofibrils. Each myofibril is made of many sarcomeres bundled … See more 1. Certain heart defects can be inherited genetically. Some of these defects occur because the genetic code responsible for creating actin or myosin is a mutant variation.
