Document Summary
Chapter 2- genes, chromosomes, cells and tissues: their structure and function in health and disease. Inheritance pattern of genes: dominant, recessive, co-dominant, sex-linked: hla system: application to organ transplantation, disease susceptibility, gene therapy: applications and limitations. Organization of cells: cells, tissues, organs, organ systems, functioning organism, an abnormality at any level of organization can cause disease. Cells group together to form tissues, tissues form organs, organs work together to form body systems. Nucleus: contains genetic information; directs metabolic function of cells. Cytoplasm: surrounds nucleus; structures carry out directions of the nucleus. Cell: basic structural and functional unit of the body. Cytoplasm: mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, centrioles, cytoskeleton. Cytoplasm: mass of protoplasm surrounded by a selectively permeable cell membrane, contains organelles. Rod-shaped structures capable of converting food material into energy to manufacture atp (adenosine triphosphate) that fuels chemical reactions in the cell.
