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


Mnemonic for 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.

there is one heart, so usually only one nucleus per heart muscle cell, but have many skeletal muscles, so have many nuclei per long fiber.
