A fascicle is a bundle of structures, typically referring to a group of muscle fibers, nerve fibers, or vascular bundles in plants. In botanical terms, it can also describe a cluster of flowers or leaves. A velamen, on the other hand, is a specialized spongy tissue found in the roots of certain epiphytic orchids, which helps in water absorption and protects the root from desiccation. Together, these terms illustrate the diversity of structures in both animal and plant Biology.

The connective tissue surrounding the fascicle of a muscle is the perimysium.
A fascicle is wrapped in perimysium, which is a connective tissue sheath that surrounds bundles of muscle fibers. It provides structural support and helps protect the muscle fibers within the fascicle.

Velamen tissue is a specialized layer of cells found in the roots of some epiphytic plants, such as orchids. Its main functions include absorbing and storing water and nutrients from the surrounding environment, as well as providing protection against desiccation and external damage. The velamen tissue is distinctive for its spongy texture and ability to regulate water uptake in these unique plant species.
