Acetylcholine (ACh) is an organic chemical that functions in the brain and body of many types of animals, including humans, as a neurotransmitter—a chemical message released by nerve cells to send signals to other cells.
Actin is a family of globular multi-functional proteins that form microfilaments.
In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise.
Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells.
Adenosine triphosphate (ATP) is a complex organic chemical that participates in many processes.
Anisotropy, is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropy.
Antonie Philips van Leeuwenhoek FRS (24 October 1632 – 26 August 1723) was a Dutch businessman and scientist in the Golden Age of Dutch science and technology.
An arthropod (from Greek ἄρθρον arthron, "joint" and πούς pous, "foot") is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and paired jointed appendages.
Benjamin Cummings specializes in science and is a publishing imprint of Pearson Education, the world's largest education publishing and technology company, which is part of Pearson PLC, the global publisher and former owner of Penguin Books and the Financial Times.
The biceps, also biceps brachii is a two-headed muscle that lies on the upper arm between the shoulder and the elbow.
Cardiac muscle (heart muscle) is one of the three major types of muscle, the others being skeletal and smooth muscle.
The endoplasmic reticulum (ER) is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae.
In physics, a force is any interaction that, when unopposed, will change the motion of an object.
German (Deutsch) is a West Germanic language that is mainly spoken in Central Europe.
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in humans, animals, fungi, and bacteria.
Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way").
A microscope (from the μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.
Muscle contraction is the activation of tension-generating sites within muscle fibers.
A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue.
A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell.
Myogenesis is the formation of muscular tissue, particularly during embryonic development.
Myomesin is an end line protein that is part of the M line.
Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes.
Nebulin is an actin-binding protein which is localized to the thin filament of the sarcomeres in skeletal muscle.
Nicotinic acetylcholine receptors, or nAChRs, are receptor proteins that respond to the neurotransmitter acetylcholine.
Phosphagens, also known as macroergic compounds, are energy storage compounds, also known as high-energy phosphate compounds, chiefly found in muscular tissue in animals.
Phosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle and the brain to recycle adenosine triphosphate, the energy currency of the cell.
Sarcoplasm is the cytoplasm of a myocyte (muscle fiber).
The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells.
Skeletal muscle is one of three major muscle types, the others being cardiac muscle and smooth muscle.
Smooth muscle is an involuntary non-striated muscle.
Sodium is a chemical element with symbol Na (from Latin natrium) and atomic number 11.
Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres, in contrast with smooth muscle tissue which does not.
Titin, also known as connectin, is a protein that, in humans, is encoded by the TTN gene.
Tropomyosin is a two-stranded alpha-helical coiled coil protein found in cell cytoskeletons.
Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones).
