An extensive network of blood vessels and nerve fibers extends through both the epimysium and the of a muscle.

An extensive network of blood vessels and nerve fibers extends through both the epimysium and the perimysium of a muscle.

Explanation:

There are many different muscles in the skeleton of the human body and each of them is a joint organ consisting of several types of tissues. Muscle fibers predominate, but there are also blood vessels, nerves and substantial amounts of connective tissue.

In a skeletal muscle the individual muscle fibers are wrapped, and held together, by several different layers of connective tissue. The perimysium is the connective tissue that surrounds each "bundle" of fibers called the fascicle. On the other hand, the epimysium is the layer of irregular dense connective tissue that envelops the muscle. The arteries, veins and lymphatic vessels that reach the muscle must pass through the layers of connective tissue. They take food and oxygen, necessary for muscle functioning.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
