Solution:
The given diagram is the cross sectional view of a muscle showing muscle bundles and muscle fibers. The labels are as follows:
Fascicle (Muscle bundle): The skeletal muscle in our body is held together by a number of muscle bundles called fascicles. These fascicles are held together by a layer of collagenous tissue known as fascia.
Muscle fiber (Muscle cell): The muscle fiber is a syncytium as its cytoplasm i.e. sarcoplasm contains many nuclei. It is the anatomical unit of muscle but the functional unit is sarcomere.
Sarcolemma: It is the membrane which encloses the muscle fibers. The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction or motor-end plate.
