Lymph nodes are the filters along the lymphatic system. Their job is to filter out and trap bacteria, viruses, cancer cells, and other unwanted substances, and to make sure they are safely eliminated from the body. Axillary lymph nodes Larger Version.
Share. By Regina Bailey. Definition: Mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of a cell. During prophase of mitosis, chromatin fibers become coiled into chromosomes with each chromosome having two chromatids joined at a centromere.
A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body. There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles.In eukaryotes, motile cilia and flagella together make up a group of organelles known as undulipodia.Eukaryotic cilia are structurally identical to Eukaryotic flagella, although distinctions are sometimes made according to function and/or length.otile cilia are usually present on a cell's surface in large numbers and beat in coordinated waves. 1  In humans, for example, motile cilia are found in the lining of the trachea (windpipe), where they sweep mucus and dirt out of the lungs.
