  • A chicken embryo, showing the [[paraxial mesoderm]] on both sides of the neural fold.  The anterior (forward) portion has begun to form [[somite]]s (labeled "primitive segments").
  • Striated skeletal muscle cells in microscopic view.  The myofibers are the straight vertical bands; the horizontal striations (lighter and darker bands) that are a visible result from differences in composition and density along the fibrils within the cells.  The cigar-like dark patches beside the myofibers are muscle-cell nuclei.
  • Three distinct types of muscle (L to R): Smooth (non-striated) muscle in internal organs, cardiac or heart muscle, and skeletal muscle.

  • When a sarcomere contracts, the Z lines move closer together, and the I band becomes smaller. The A band stays the same width. At full contraction, the thin and thick filaments overlap.
  • (a) Some ATP is stored in a resting muscle. As contraction starts, it is used up in seconds. More ATP is generated from creatine phosphate for about 15 seconds. (b) Each glucose molecule produces two ATP and two molecules of pyruvic acid, which can be used in aerobic respiration or converted to [[lactic acid]]. If oxygen is not available, pyruvic acid is converted to lactic acid, which may contribute to [[muscle fatigue]]. This occurs during strenuous exercise when high amounts of energy are needed but oxygen cannot be sufficiently delivered to muscle. (c) Aerobic respiration is the breakdown of glucose in the presence of oxygen (O2) to produce carbon dioxide, water, and ATP. Approximately 95 percent of the ATP required for resting or moderately active muscles is provided by aerobic respiration, which takes place in mitochondria.
  • ATPase staining of a muscle cross section. Type II fibers are dark, due to the alkaline pH of the preparation. In this example, the size of the type II fibers is considerably less than the type I fibers due to denervation atrophy.
  • Types of [[pennate muscle]]. A – [[unipennate]];  B – [[bipennate]]; 
C – [[multipennate]]
  • [[Human embryo]] showing [[somite]]s labelled as ''primitive segments''.
  • polypeptide]] tail (only one tail of each pair is shown). The pairs of histones, H2A, H2B, H3 and H4, each have [[lysine]]s (K) in their tails, some of which are subject to post-translational modifications consisting, usually, of acetylations [Ac] and methylations {me}. The lysines (K) are designated with a number showing their position as, for instance, (K4), indicating lysine as the 4th amino acid from the amino (N) end of the tail in the histone protein. The particular acetylations [Ac] and methylations {Me} shown are those that occur on nucleosomes close to, or at, some DNA regions undergoing transcriptional activation of the DNA wrapped around the nucleosome.
  • Prisoner of war exhibiting muscle loss as a result of [[malnutrition]].
  • [[Jogging]] is one form of aerobic exercise.
  • Muscle types by fiber arrangement
  • Exercise-induced signaling pathways in skeletal muscle that determine specialized characteristics of slow- and fast-twitch muscle fibers
  • In [[muscular dystrophy]], the affected tissues become disorganized and the concentration of [[dystrophin]] (green) is greatly reduced.

'''Regulation of transcription in mammals.'''  An active enhancer regulatory region is enabled to interact with the promoter region of its target gene by formation of a chromosome loop. This can allow initiation of messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one architectural protein anchored to the enhancer and one anchored to the promoter, and these proteins are joined together to form a dimer (red zigzags). Specific regulatory transcription factors bind to DNA sequence motifs on the enhancer. General transcription factors bind to the promoter. When a transcription factor is activated by a signal (here indicated as phosphorylation shown by a small red star on a transcription factor on the enhancer) the enhancer is activated and can now activate its target promoter. The active enhancer is transcribed on each strand of DNA in opposite directions by bound RNAP IIs. Mediator (a complex consisting of about 26 proteins in an interacting structure) communicates regulatory signals from the enhancer DNA-bound transcription factors to the promoter.

Spasm

A spasm is a sudden involuntary contraction of a muscle, a group of muscles, or a hollow organ such as the bladder.

A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain. A muscle cramp is usually harmless and ceases after a few minutes. It is typically caused by ion imbalance or muscle overload.

There are other causes of involuntary muscle contractions, and some of these may cause a health problem.
