What is the function of a skeletal muscle cell

• Carry electrical messages to and from the brain to every part of the body. They are the communication center

• Move the bones in our bodies so that the limbs of the organism are able to move

• To carry and deliver oxygen to different tissues around the body that need it

Muscle cells are large so that they can...

• These must be long (large) so that signals can be sent along them quickly

• These must be long (large) so that they can contract and work with other cells by overlapping with them like a rope

• Vessels that these cells travel in move very fast so they need to be this size to protect themselves from the speed of the flow

• These must be long (large) so that they are strong enough to do the job

• These must be long (large) so that they do not easily move

Muscle cells have a ______ shape

• Flat

• round

• Thin like a wire

• Thin like a rubber band

• Thick like a brick

Muscle cells have a shape that is flat and round for this purpose

• allows many of the cells to overlap to work together to flex and move items

• allows the cells to be stronger for its size allowing it to more easily move the skeleton/bone

• allows signals to be sent along them quickly

• allows them to fit into narrow spaces and turn corners easily

• allows them to be aerodynamic so they can turn quickly

• Cell Shape

• Cell Size

• Cell Organelles

• All choices

These are like wires. They help communicate between different parts of the body (arm to brain)

• Connective Cells

• Epithilial Cells

• Muscle Cells

• Nerve Cells (neurons)
