sarcoplasmic reticulum

Definition

Target type: cellularcomponent

A fine reticular network of membrane-limited elements that pervades the sarcoplasm of a muscle cell; continuous over large portions of the cell and with the nuclear envelope; that part of the endoplasmic reticulum specialized for calcium release, uptake and storage. [GOC:mtg_muscle, ISBN:0124325653, ISBN:0198547684]

The sarcoplasmic reticulum (SR) is a specialized form of endoplasmic reticulum found in muscle cells. It is a network of interconnected membrane-bound sacs and tubules that encircle the myofibrils, the contractile units of muscle fibers. The SR plays a crucial role in regulating calcium ion concentration, which is essential for muscle contraction.

The SR can be divided into two main regions: the terminal cisternae and the longitudinal tubules. The terminal cisternae are flattened sacs that lie adjacent to the transverse tubules (T-tubules), which are invaginations of the plasma membrane that penetrate into the muscle fiber. The longitudinal tubules run parallel to the myofibrils and connect the terminal cisternae.

The SR stores a high concentration of calcium ions. When a muscle fiber is stimulated, the action potential travels along the T-tubules and triggers the release of calcium ions from the SR into the sarcoplasm, the cytoplasm of the muscle cell. The calcium ions then bind to troponin, a protein associated with the thin filaments of the myofibrils. This binding event initiates the sliding filament mechanism of muscle contraction.

After contraction, the calcium ions are actively transported back into the SR by the calcium ATPase pump, restoring the resting calcium concentration and allowing the muscle to relax.

In summary, the sarcoplasmic reticulum is a highly specialized and dynamic organelle that plays a critical role in muscle contraction. It acts as a calcium store and release system, ensuring the precise regulation of calcium ion concentration, which is essential for the initiation and termination of muscle contraction.'

metronidazolemetronidazole : A member of the class of imidazoles substituted at C-1, -2 and -5 with 2-hydroxyethyl, nitro and methyl groups respectively. It has activity against anaerobic bacteria and protozoa, and has a radiosensitising effect on hypoxic tumour cells. It may be given by mouth in tablets, or as the benzoate in an oral suspension.

It is highly effective for the treatment of opioid use disorder and is also increasingly being used in the treatment of chronic pain.

Buprenorphine: A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
