(noun)

embryonic shoot that lies at the junction of the stem and petiole that gives rise to a branch or flower

Examples of axillary bud in the following topics:

  • Functions of Stems

    • A stem connects the roots to the leaves, provides support, stores food, and holds the leaves, flowers, and buds.
    • Their main function is to provide support to the plant, holding leaves, flowers, and buds; in some cases, stems also store food for the plant.
    • An axillary bud is usually found in the axil (the area between the base of a leaf and the stem) where it can give rise to a branch or a flower.
    • The apex (tip) of the shoot contains the apical meristem within the apical bud.
    • The leaves just above the nodes arise from axillary buds.

  • Stem Modifications

    • Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns.
    • Tubers arise as swollen ends of stolons, and contain many adventitious or unusual buds (familiar to us as the "eyes" on potatoes).
    • Modifications to the aerial stems, vegetative buds, and floral buds of plants perform functions such as climbing, protection, and synthesis of food vegetative propagation .
    • These may develop from either the axillary bud or the terminal bud of the stem.
    • Bulbils are axillary buds that have become fleshy and rounded due to storage of food.

  • Primary and Secondary Growth in Stems

    • The influence of the apical bud on overall plant growth is known as apical dominance, which diminishes the growth of axillary buds that form along the sides of branches and stems.
    • If the apical bud is removed, then the axillary buds will start forming lateral branches.
    • Gardeners make use of this fact when they prune plants by cutting off the tops of branches, thus encouraging the axillary buds to grow out, giving the plant a bushy shape.

  • Brachial Plexus

    • It is a collection of nerves passing through the cervico-axillary canal to reach the axilla and supplies the brachium, the antebrachium, and the hand.
    • The cords are named by their position with respect to the axillary artery: The posterior cord is formed from the three posterior divisions of the trunks (C5-C8,T1), the lateral cord is the anterior divisions from the upper and middle trunks (C5-C7), and the medial cord is simply a continuation of the anterior division of the lower trunk (C8,T1)

  • Gustation: Taste Buds and Taste

    • The tongue contains papillae, or specialized epithelial cells, which have taste buds on their surface.
    • There are three types of papillae with taste buds in the human gustatory system:
    • Each taste bud is flask-like in shape and formed by two types of cells: supporting cells and gustatory cells.
    • A schematic drawing of a taste bud and its component pieces.
    • Compare the structural similarities and differences among types of taste buds

  • Veins of the Upper Limbs

    • At the shoulder the basilic vein passes deep into the arm and merges with the brachial veins to form the axillary vein, to which the cephaliac vein merges forming the subclavian vein.

  • Fungi Reproduction

    • Fungi can reproduce asexually by fragmentation, budding, or producing spores, or sexually with homothallic or heterothallic mycelia.
    • Fungi reproduce asexually by fragmentation, budding, or producing spores.
    • Somatic cells in yeast form buds.
    • During budding (a type of cytokinesis), a bulge forms on the side of the cell, the nucleus divides mitotically, and the bud ultimately detaches itself from the mother cell.
    • Yet others bud off the vegetative parent cell.

  • Types of Sexual and Asexual Reproduction

    • Animals may reproduce asexually through fission, budding, fragmentation, or parthenogenesis.
    • Budding is a form of asexual reproduction that results from the outgrowth of a part of a cell or body region leading to a separation from the original organism into two individuals.
    • Budding occurs commonly in some invertebrate animals such as corals and hydras .
    • In hydras, a bud forms that develops into an adult, which breaks away from the main body; whereas in coral budding, the bud does not detach and multiplies as part of a new colony.
    • Hydra reproduce asexually through budding, where a bud forms that develops into an adult and breaks away from the main body.

  • Signaling in Yeast

    • Budding yeasts are able to participate in a process that is similar to sexual reproduction that entails two haploid cells combining to form a diploid cell .
    • In order to find another haploid yeast cell that is prepared to mate, budding yeasts secrete a signaling molecule called mating factor.
    • Budding Saccharomyces cerevisiae yeast cells can communicate by releasing a signaling molecule called mating factor.

  • Replication of Herpes Simplex Virus

    • Herpes replication entails three phases: gene transcription, viral assembly in the nucleus, and budding through the nuclear membrane.
    • The primary envelope is acquired by budding into the inner nuclear membrane of the cell.
    • The virus acquires its final envelope by budding into cytoplasmic vesicles.
