Bonjour, L'anneau initial est à l'origine de la formation des feuilles et de l'écorce. Se sont les divisions dans l'anneau initial qui déterminent les formations : d'abord périclines profondes donnent l'écorce et la future tige, puis périclines superficielles qui vont conduire à l'initium foliaire ainsi que des divisions longitudinales profondes simultanées qui vont donner le procambium Transcript.

The tunica media is the substantial middle layer of the vessel wall (see Figure 2). It is generally the thickest layer in arteries, and it is much thicker in arteries than it is in veins. The tunica media consists of layers of smooth muscle supported by connective tissue that is primarily made up of elastic fibers, most of which are arranged in. The tunica intima consists of the endothelium, connective tissue (collagen, laminin, fibronectin, and other extracellular matrix molecules), and a basal layer of elastic tissue called internal elastic lamina that separates the tunica intima from tunica media. Endothelium is a thin monolayer of cells that serves as the contact surface with blood tunica [too´nĭ-kah] (L.) a tunic or coat; used in anatomic nomenclature to designate a membranous covering of an organ or a distinct layer of the wall of a hollow structure, as a blood vessel. tunica adventi´tia the outer coat of various tubular structures. tunica albugi´nea a dense white fibrous sheath that encloses a part or organ, such as the.

The tunica intima (also called the tunica interna) is composed of epithelial and connective tissue layers. Lining the tunica intima is the specialized simple squamous epithelium called the endothelium, which is continuous throughout the entire vascular system, including the lining of the chambers of the heart Tunica media je střední vrstva krevní a lymfatické stěny spolu s tunica intima (vnitřní vrstva) a tunica adventitia (vnější vrstva). Od vnitřní vrstvy se liší svou barvou a odlišnou orientací vláken. Ve velkých artériích jsou vrstvy oddělené membránami- mezi tunica media a tunica adventitia se vyskytuje elastica externa a mezi tunica media a tunica intima se nachází. * The tunica media is the layer of concentrically-arranged smooth muscle, the autonomic control of which. can alter the diameter of the vessel and affect the blood pressure. Smooth muscle cells (in contrast to cardiac. and skeletal) have secretory capabilities, and (depending on the vessel), the tunica media contains varying It appears that virtually all SAMs have a Tunica layer on the surface of the meristem proper. This divides anticlinally and gives rise to the Protoderm. The surface Tunica layer covers a multicellular, dome shaped region in which anticlinal, periclinal and oblique divisions occur. The latter is the Corpus or Central Mother Cell Zone (CMCZ)

The tunica intima is constituted by endothelium and a very small endothelial space. The tunica media is formed mainly by smooth muscle and has a thickness similar to the tunica adventitia.
