Also known as a myocyte when referring to either a cardiac muscle cell , or a smooth muscle cell as these are both small cells.
The cytoplasm in a muscle cell is termed the sarcoplasm; the smooth endoplasmic reticulum of a muscle cell is termed the sarcoplasmic reticulum; and the cell membrane in a muscle cell is termed the sarcolemma.
Smallest functional unit of striated muscle tissue.
The concentration of calcium within muscle cells is controlled by the sarcoplasmic reticulum, a unique form of endoplasmic reticulum in the sarcoplasm.
Cell membrane of a muscle cell.
A special feature of the sarcolemma is that it invaginates into the sarcoplasm of the muscle cell, forming membranous tubules radially and longitudinally within the fiber called T-tubules or transverse tubules.
Part of the cardiac cycle during which some chambers of the heart muscle contract after refilling with blood.
These cells are activated spontaneously by depolarization of the electrical potential across their cell membranes, which causes voltage-gated calcium channels on the cell membrane to open and allow calcium ions to pass through into the sarcoplasm (cytoplasm) of cardiac muscle cells.
Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system that are mostly attached by tendons to bones of the skeleton.
The cell membrane is called the sarcolemma with the cytoplasm known as the sarcoplasm.
Myofilaments are the three protein filaments of myofibrils in muscle cells.
Calcium ions are then released from the sarcoplasmic reticulum into the sarcoplasm and subsequently bind to troponin.
Swiss anatomist, physiologist, and histologist.
Albert L. Lehninger asserted that Kölliker was among the first to notice the arrangement of granules in the sarcoplasm of striated muscle over a period of years beginning around 1850.
Strength training or resistance training involves the performance of physical exercises that are designed to improve strength and endurance.
Exercises of 6–12 reps cause hypertrophy of the sarcoplasm in slow-twitch and high-twitch muscle fibers, contributing to overall increased muscle bulk.
Naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
The average concentration of HMB in the intramuscular fluid of healthy men of ages 21–23 has been measured at 7.0 μM.
German anatomist born in Hanover.
"Krause's membranes": defined as isotropic bands in striated muscle fiber that consist of disks of sarcoplasm and connect the individual fibrils. Also known as Z-Disc or Dobie's line.
