  2. Plant embryonic development - Wikipedia

    en.wikipedia.org/wiki/Plant_embryonic_development

    Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]

  3. Hamstring - Wikipedia

    en.wikipedia.org/wiki/Hamstring

    The biceps femoris is most commonly injured, followed by semitendinosus. Semimembranosus injury is rare. Imaging is useful in differentiating the grade of strain, especially if the muscle is completely torn. [10] In this setting, the level and degree of retraction can be determined, serving as a useful roadmap prior to any surgery.

  4. Pes anserinus (leg) - Wikipedia

    en.wikipedia.org/wiki/Pes_anserinus_(leg)

    The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. [1] [2] It inserts onto the proximal anteromedial surface of the tibia. [2] The pes anserinus is around 5 cm below the medial tibial joint line. [2]

  5. Plant morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_morphology

    Growth from any such meristem at the tip of a root or shoot is termed primary growth and results in the lengthening of that root or shoot. Secondary growth results in widening of a root or shoot from divisions of cells in a cambium. [8] In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual ...

  6. Primary growth - Wikipedia

    en.wikipedia.org/wiki/Primary_growth

    In contrast, a growth process that involves thickening of stems takes place within lateral meristems that are located throughout the length of the stems. The lateral meristems of larger plants also extend into the roots. This thickening is secondary growth and is needed to give mechanical support and stability to the plant. [4]

    Each plant commences its growth as a herbaceous plant. Plants that remain herbaceous are shorter and seasonal, dying back at the end of their growth season. Woody plants (such as trees, shrubs and woody vines ( lianas ) will gradually acquire woody (lignaceous) tissues, which provide strength and protection for the vascular system , [ 4 ] and ...

  8. Anatomical terms of muscle - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_muscle

    A muscle that fixes or holds a bone so that the agonist can carry out the intended movement is said to have a neutralizing action. A good famous example of this are the hamstrings; the semitendinosus and semimembranosus muscles perform knee flexion and knee internal rotation whereas the biceps femoris carries out knee flexion and knee external ...

  9. Plant anatomy - Wikipedia

    en.wikipedia.org/wiki/Plant_anatomy

    Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
