  • Lens Capsule, Crystalline
    anatomy The thin noncellular outer covering of the CRYSTALLINE LENS composed mainly of COLLAGEN TYPE IV and GLYCOSAMINOGLYCANS. It is secreted by the ...
  • Limb Buds
    anatomy Distinct regions of mesenchymal outgrowth at both flanks of an embryo during the SOMITE period. Limb buds, covered by ECTODERM, give rise to ...
  • Meckel Diverticulum
    anatomy A congenital abnormality characterized by the outpouching or sac formation in the ILEUM. It is a remnant of the embryonic YOLK SAC in which the...
  • Mesencephalon
    anatomy The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, ...
  • Mesoderm
    anatomy The middle germ layer of an embryo derived from three paired mesenchymal aggregates along the neural tube.
  • Morula
    anatomy An early embryo that is a compact mass of about 16 BLASTOMERES. It resembles a cluster of mulberries with two types of cells, outer cells and ...
  • Mullerian Ducts
    anatomy A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of ...
  • Muscle Cells
    anatomy Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal (MUSCLE FIBERS, ...
  • Myoblasts
    anatomy Embryonic (precursor) cells of the myogenic lineage that develop from the MESODERM. They undergo proliferation, migrate to their various sites,...
  • Neural Plate
    anatomy The region in the dorsal ECTODERM of a chordate embryo that gives rise to the future CENTRAL NERVOUS SYSTEM. Tissue in the neural plate is ...
  • Neural Stem Cells
    anatomy Self-renewing cells that generate the main phenotypes of the nervous system in both the embryo and adult. Neural stem cells are precursors to ...
  • Neural Tube
    anatomy A tube of ectodermal tissue in an embryo that will give rise to the CENTRAL NERVOUS SYSTEM, including the SPINAL CORD and the BRAIN. Lumen ...
  • Neurites
    anatomy In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of ...
  • NIH 3T3 Cells
    anatomy A continuous cell line of high contact-inhibition established from NIH Swiss mouse embryo cultures. The cells are useful for DNA transfection ...
  • Notochord
    anatomy A cartilaginous rod of mesodermal cells at the dorsal midline of all CHORDATE embryos. In lower vertebrates, notochord is the backbone of ...
