Explain the structure of striated (skeletal muscle) and compare the muscle structure in areas of the body that move frequently to those that move less frequently
:)
Striated muscles are composed of multiple muscle fibers that are bundled together by connective tissue. These fibers are long, cylindrical cells that can range in length from a few millimeters to several centimeters. Each muscle fiber contains multiple myofibrils that are responsible for the contraction of the muscle. Myofibrils contain two types of filaments: thin actin filaments and thick myosin filaments. These filaments are arranged in a repeating pattern called sarcomeres, which are the basic units of striated muscle.
In areas of the body that move frequently, such as the hands and feet, the muscle structure tends to be more complex and contains smaller motor units. This allows for finer movement and greater dexterity. In contrast, areas of the body that move less frequently, such as the back or thigh muscles, have larger and less complex muscle fibers. This allows these muscles to generate more force, but with less precision. Additionally, some muscles in the body, such as the heart and smooth muscles, do not have striations and have a different structure suited for their specific functions.
hi
Hello! How can I assist you today?
can you answer a question about a series? i remember a scene but I don't know where its from. could you possibly help me?
Sure! I'll do my best to help. What's the scene you remember?
Okay, so, what I remember in the scene was some kind of monster/creature. I think it was blue and black. It froze people in fear whenever thy would into some kind of garden, can't remember the name. The dialogue was something like this "[NAME], run." and the other character says, "I can't", due to being frozen in fear.
Hmm, this sounds familiar. Do you have any other details or context to share? For example, do you remember the genre of the series, any of the characters or actors, or any other scenes or plot points?
I think it was a new superhero movie. I watch a lot of superhero movies though so i wouldn't know which one.
Based on your description, the scene you're thinking of might be from the 2019 superhero film "Shazam!".
In one scene, the villainous Dr. Sivana releases the Seven Deadly Sins, a group of demons that personify different sins. One of the Sins is called Envy and has a blue and black appearance. Envy possesses the ability to make people freeze in fear with her gaze, and can also transport people to a secret garden called The Rock of Eternity.
There is a scene in which a character named Freddy Freeman (played by Jack Dylan Grazer) is confronted by Envy. When his friend Billy Batson (played by Asher Angel) appears and tells him to run, Freddy says "I can't", as he is frozen in fear.
If this isn't the scene you're thinking of, let me know and I'll do my best to help you figure it out!
