[[Muscles - Anatomy & Physiology|Muscle]] cells can come from two lineages in the [[Developmental Biology - Somite Development - Anatomy & Physiology|somite]]. Limb and body muscle develop from hypaxial muscle in the lateral regions of the somite. Back muscle develops from epaxial muscle in the dorsal regions of the somite. Muscle fibres have hundreds of nuclei and function as a syncytium.
