Sarcomere Flashcards
What are three of the functions of Skeletal Muscle?
Force generation for breathing and movement Force generation for postural support Heat production during cold stress
Where is the M line on the Sarcomere?
The M line is directly in the middle which looks white in colour
What is the technical name for when heat is produced during cold stress?

The I band is located on the white band on either side of the A band. It is not located in the middle.

How much water is in muscle?
approximately 75%
Where is the A band in the sarcomere?
The area that is constituted with the thick filaments which gives the dark pigment of the sarcomere.
How many skeletal muscles are in the human body?
Over 600
Where is the Z line on the Sarcomere?
The Z line is on either side of the Sarcomere, in the form of a zig-zag line
Why is Titan in the sarcomere called Titan?
It is the largest protien in the human body, hence the name Titan meaning Giant.
Where is Titan located on the Sarcomere?
Titan is located Near the Z line, it’s the coil like structure
