Muscle cells: cardiac vs. skeletal's nuclei location/number

Nuclei location mirrors where the muscle is located in human body.
Heart muscle is in the middle of body, so heart muscle has nucleus in middle.
Skeletal muscles are at periphery of body, so nuclei are at periphery.
Also, you have 1 heart, so usually only 1 nucleus per heart muscle cell, but have many skeletal muscles, so have many nuclei per long fibre.
