Question

Within each of the skeletal muscles are bundles of muscle fibers. These bundles are also called

Answer 1

The bundles of muscle fibers within skeletal muscles are known as fascicles, which are organized by the connective tissue sheath perimysium. Each muscle fiber within a fascicle is surrounded by endomysium, providing nutrients through blood supply. The striated appearance of these muscles is due to the arrangement of sarcomeres, the basic units of muscle contraction.

Step-by-step explanation:

Within each of the skeletal muscles are bundles of muscle fibers. These bundles are also called fascicles. Inside each skeletal muscle, muscle fibers are organized into these individual bundles which are surrounded by a connective tissue sheath called the perimysium. This organization into fascicles is essential for muscle function as it allows for specific movements to be controlled by the nervous system through the activation of particular subsets of muscle fibers.

The individual muscle fibers within each fascicle are further wrapped in a thin layer of connective tissue called the endomysium, which holds the extracellular fluid and nutrients that support the muscle fiber. These nutrients are supplied by the blood to the muscle tissue. Furthermore, the arrangement of protein filaments within the muscle fibers gives the skeletal muscle its striated appearance, with repeating units called sarcomeres being the basic functional units of muscle contraction.

Answer 2

These bundles are also called Fascicles

Step-by-step explanation:

Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. muscle is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. A skeletal muscle refers to multiple bundles (fascicles) of cells joined together called muscle fibers.

The bundles of muscle fibers are called fascicles, they are covered by the perimysium. Muscle fibers are covered by the endomysium. Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium.
