The arm muscles are made up of muscle fibers or skeletal muscles. The shape of the body is held together with the help of these muscles.
Skeletal muscle cells
Cell membranes are composed primarily of phospholipids. These phospholipids form a lipid bilayer that acts as a barrier to the passage of most molecules. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.
Skeletal muscles are primarily utilized when a person walks.

Cardiac cell muscles
The molecule cell is the main cell found. This cell contains nucleptidees.
It depends on the type of meteorite. Stony meteorites are composed primarily of Iron and Magnesium silicates. Stony-Iron meteorites are composed primarily of silicates and Iron and Nickel metals. Iron Meteorites are composed primarily of Iron and Nickel metal and Iron sulphide.
The chest muscles, also known as the pectoralis muscles, are primarily composed of fast-twitch muscle fibers. These muscle fibers are responsible for generating quick and powerful contractions, which are important for movements like pushing and pressing.
The white pulp of the spleen is primarily composed of lymphocytes, which are a type of white blood cell involved in the immune response. This area of the spleen is responsible for filtering the blood and detecting and responding to foreign invaders, such as bacteria and viruses.
The epidermis is primarily composed of stratified squamous epithelium. This type of epithelium is well-suited to protect the skin from physical damage and external threats.
The upper arm is primarily composed of skeletal muscle. Specifically, muscles such as the biceps brachii and triceps brachii are responsible for movement and stability in the upper arm. These muscles are attached to the bones by tendons and are under voluntary control.
The simplest unit of life is the cell. Cells are the basic building blocks of all living organisms and can vary in size, shape, and function. Tissues are made up of groups of cells, organs are made up of groups of tissues, and muscles are a type of tissue composed of specialized cells.
