  • (20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.

Endosteum


Definition:

  • (n.) The layer of vascular connective tissue lining the medullary cavities of bone.

Example Sentences:
