Muscle cells come in three main types - skeletal, cardiac, and smooth. Skeletal muscle cells are found throughout the body, attach to bones, and allow for movement by contracting. They are striated and look striped but tire quickly. Cardiac muscle cells are only found in the heart walls and help power heartbeats. Smooth muscle cells are involuntary and found throughout systems like breathing and digestion, reacting slowly but enduringly.

1. By Francesca M., Isabella P. and Mathilde S. What is a muscle cell?

2. An extended contraction cell that forms the muscles of the body There are three types: Skeletal-found throughout the body Cardiac-found in the walls of the heart Smooth-found in a number of systems throughout the body A muscle cell is...

3. Usually attached to bones By contracting skeletal muscles, it causes different body parts to move They are often called striated muscles because they look striped They react quickly but they also tire quickly Can be very long and sometimes over 30 cm Skeletal

4. Fibers branch out in many directions The contraction of these fibers make the heart beat It is also striped Cardiac

5. Also called involuntary muscles They appear smoother than other muscles They help control breathing, blood pressure, the movement of the digestive system and the eyes Unlike skeletal muscles they react slowly and tire slowly Only have one nucleus Smooth
