Fascicle or fasciculus may refer to:
In anatomy:
  • Muscle fascicle
    Muscle fascicle
    In anatomy, a fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.Specialized muscle fibers in the heart that transmit electrical impulses from the Atrioventricular Node to the Purkinje Fibers are fascicles, also referred to as bundle branches...

    , a bundle of skeletal muscle fibers surrounded by connective tissue.
  • Nerve fascicle
    Nerve fascicle
    A small bundle of nerve fibers, enclosed by the perineurium, is called a funiculus; if the nerve is of small size, it may consist only of a single funiculus; but if large, the funiculi are collected together into larger bundles or nerve fascicles, which are bound together in a common membranous...

    , a bundle of axons (nerve fibers) enclosed by the perineurium.
    • Superior longitudinal fasciculus
      Superior longitudinal fasciculus
      The superior longitudinal fasciculus is a pair of long bi-directional bundles of neurons connecting the front and the back of the cerebrum. Each association fiber bundle is lateral to the centrum ovale of a cerebral hemisphere and connects the frontal, occipital, parietal, and temporal lobes...

      • Arcuate fasciculus
        Arcuate fasciculus
        The arcuate fasciculus is the neural pathway connecting the posterior part of the temporoparietal junction with the frontal cortex in the brain and is now considered as part of the superior longitudinal fasciculus..-Neuroanatomy:...

    • Gracile fasciculus
    • Cuneate fasciculus
    • Dorsal longitudinal fasciculus
      Dorsal longitudinal fasciculus
      The dorsal longitudinal fasciculus is a white matter fiber tract located within the brain stem, specifically in the dorsal brainstem tegmentum. The DLF travels through the periaqueductal gray matter...

    • Medial longitudinal fasciculus
      Medial longitudinal fasciculus
      The medial longitudinal fasciculus is a pair of crossed fiber tracts , one on each side of the brainstem. These bundles of axons are situated near the midline of the brainstem and are composed of both ascending and descending fibers that arise from a number of sources and terminate in different...

    • Flechsig's fasciculus


In botany:
  • Fascicle (botany)
    Fascicle (botany)
    In botany, a fascicle is a bundle of leaves or flowers, or of the vascular tissues that supply these organs with nutrients...

    , a cluster of flowers or leaves, such as the bundles of the thin leaves (or needles) of pines
  • A discrete bundle of vascular tissue
    Vascular tissue
    Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue:...

  • A discrete section of a literary serial
    Serial (literature)
