Fig 1: Components of skeletal muscle fibre

Explanation of Solution

The fascicles are bundles of skeletal muscles that are enveloped by connective tissues, which is termed as perimysium. The epimysium is a type of connective tissue that envelops every muscle. The areolar connective tissue that is present inside the muscle is termed as endomysium. This structure composes of nerves as well as capillaries and overlies the sarcolemma. Muscle fibers are smaller in size and they are present inside the fascicle. Myofibrils are rod-like structures and form the basic unit of muscle. They are made of thick and thin filaments.

Fig 2: Components of the fascicle

Explanation of Solution

A muscle fascicle is formed of a bunch of skeletal muscle fibers. These fibers are enveloped by connective tissues known as perimysium. The areolar connective tissue that is present inside the muscle is termed as endomysium. Muscle fibers are smaller structures that are present inside the fascicle. The sarcolemma is a fine, tube-like structure that surrounds the fibres in skeletal muscles. Myofibrils are rod-like structures and form the basic unit of muscle. They are made of thick and thin filaments.

Explanation of Solution

Skeletal muscle cells appear as long, cylindrical structures; therefore, they are generally referred to as muscle fibers. They are structured into a cluster known as fascicles. The epimysium spreads between fascicles internally, forming septa, which are called perimysium. The perimysium further stretches into thinner strands known as endomysium.

Answer to Problem 1.1BGL

Explanation of Solution

To label: The cross-section of a fascicle in a muscle in Fig 12.2 (a). Introduction: The force that can be generated by a muscle fiber is determined by the muscle fascicle. Tendons are structures that connect the muscle with the bones. This junction is highly prone to injuries.
