  2. Mitragyna speciosa - Wikipedia

    en.wikipedia.org/wiki/Mitragyna_speciosa

    Mitragyna speciosa is a tropical evergreen tree of the Rubiaceae family (coffee family) native to Southeast Asia. [3] It is indigenous to Cambodia, Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, [4] where its leaves, known as kratom, have been used in herbal medicine since at least the 19th century. [5]

    en.wikipedia.org/wiki/Mitragynine

    Mitragynine is an indole-based alkaloid and is one of the main psychoactive constituents in the Southeast Asian plant Mitragyna speciosa, commonly known as kratom. [4] It is an opioid that is typically consumed as a part of kratom for its pain-relieving and euphoric effects.

  4. High endothelial venules - Wikipedia

    en.wikipedia.org/wiki/High_endothelial_venules

    Despite intensive efforts, few HEV-specific markers have been described. The best HEV marker currently available is a carbohydrate epitope recognized by the monoclonal antibody (mAb) MECA-79, which stains all HEVs within lymphoid tissues and does not react with postcapillary venules or large vessels in spleen, thymus or nonlymphoid tissues.

  5. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    The tunica media may (especially in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel. Veins do not have the external elastic lamina, but only an internal one. The tunica media is thicker in the arteries rather than the veins. The outer layer is the tunica adventitia and the thickest layer in veins. It is ...

  6. Sarcoplasm - Wikipedia

    en.wikipedia.org/wiki/Sarcoplasm

    Sarcoplasm is the cytoplasm of a muscle cell. It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycogen (a polymer of glucose), myoglobin, a red-colored protein necessary for binding oxygen molecules that diffuse into muscle fibers, and mitochondria.

  7. Lateral force transmission in skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Lateral_Force_Transmission...

    Muscles contain far more perimysial than endomysial connective tissue, and it has also been observed that the ratio of the dry mass of perimysium to that of endomysium ranges between 2.8-1 and 64–1. [13] The anatomical arrangement of the connective tissue at each level of organization influences the function of the muscle.

  8. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins, present are two regulatory proteins, troponin and tropomyosin. [1] Muscle tissue varies with function and location in the body. In vertebrates, the three types are: skeletal, cardiac (both striated), and

  9. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
