Disruption sequenceThe events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
RELATED TERMS--------------------------------------
Fetus
The stage of human development from 10 weeks' gestation until birth.
Rubella
A mild, highly contagious viral disease that can cause serious birth defects if a pregnant woman is afflicted. Women who haven't had it should make sure they're immunized before conception.
Virus
Ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Disorder, social anxiety
Excessive fear of embarrassment in social situations that is extremely intrusive and can have debilitating effects on personal and professional relationships. Also called social phobia. Phobias are persistent, irrational fears of certain objects or situations. They recognize that their fear may be excessive or unreasonable, but are unable to overcome it. The symptoms and signs of social phobia include blushing, sweating, trembling, rapid heartbeat, muscle tension, nausea or other stomach discomfort, lightheadedness, and other symptoms of anxiety.
Disorder, specific developmental
A disorder that selectively affects one area of development, sparing essentially all other areas of development. Specific developmental disorders are as opposed to pervasive developmental disorders (which affect development across the board), dyspraxias that affect multiple systems, cerebral palsy, and metabolic disorders.
Disordered thinking
A failure to be able to "think straight." Thoughts may come and go rapidly. The person may not be able to concentrate on one thought for very long and may be easily distracted, unable to focus attention. The person may be unable to connect thoughts into logical sequences, with thoughts becoming disorganized and fragmented. This lack of logical continuity of thought, termed a "thought disorder," can make conversation very difficult and may contribute to social isolation. If people cannot make sense of what an individual is saying, they are likely to become uncomfortable and tend to leave that person alone. Disorder thinking is a characteristic feature of schizophrenia.
Disorders, lymphoproliferative
Malignant diseases of the lymphoid cells and cells from the reticuloendothelial system (which take up and sequester inert particles). The lymphoproliferative disorders are in contrast to the myeloproliferative disorders which are malignancies of certain bone marrow cells including those that give rise to the red blood cells, the granulocytes (types of white blood cells), and the platelets (crucial to blood clotting).
Disorders, myeloproliferative
Malignant diseases of certain bone marrow cells including those that give rise to the red blood cells, the granulocytes (types of white blood cells), and the platelets (crucial to blood clotting). The myeloproliferative disorders include myelophthisic anemia, erythroblastic leukemia, leukemoid reaction, myelofibrosis, myeloid metaplasia, polycythemia vera, and thrombocytosis. The myeloproliferative disorders are in contrast to the lymphoproliferative disorders which are malignancies of lymphoid cells and cells of the reticuloendothelial system (such as macrophages) which can take up inert particles and sequester them.
Disruption sequence
Dissect
To cut apart or separate tissue as, for example, for anatomical study or in surgery. Also, an artery is said to dissect when its wall is torn, as in a dissecting aneurysm.
Dissection
The process of cutting apart or separating tissue as, for example, in the study of anatomy or in the course of a surgical procedure.
Dissection, axillary
Surgery in which the axilla (the armpit) is opened -- to "dissect" means to "cut apart" -- in order to identify, examine, and sometimes remove structures such as lymph nodes or other tissue for diagnosis or treatment.
Dissection, neck
Surgery in which the neck is opened -- to "dissect" means to "cut apart" -- in order to identify, examine, and sometimes remove structures such as lymph nodes or other tissue for diagnosis or treatment. A radical neck dissection involves removal of a tumor from the neck with an additional margin of apparently normal tissue of at least 2 cm, as well as removal of the lymph nodes from the neck.
Distance healing
Healing in which people seek to help patients simply with the power of the mind. Distance healing can include anything from therapeutic touch -- in which practitioners, without touching their patients, try to alter their energy fields -- to praying for people who are ill. Distance healing is part of the practice of alternative medicine.
