Riassunto

Il più vasto tessuto del corpo umano è quello muscolare. Esistono tre tipi di cellule muscolari: lisce, striate e miocardiche. Le cellule muscolari lisce sono quelle della cosiddetta muscolatura involontaria (organi interni, vasi sanguigni), hanno forma appiattita e sono mononucleate. Al contrario, le cellule muscolari striate sono polinucleate e la loro contrazione è sotto il diretto controllo della volontà: i movimenti degli arti, come il mantenimento del tono posturale, sono assicurati da questo tipo di muscolatura. Per il loro aspetto fusiforme, le miocellule striate sono anche denominate fibre e contengono un numero di miofibrille parallele. Infine, le cellule muscolari del miocardio rappresentano il tessuto contrattile del cuore e sono molto simili alle cellule muscolari striate, sebbene la loro contrazione sia involontaria e regolata da fibre nervose collocate in un’area dell’atrio destro del cuore, cioè il nodo seno-atriale.
