projection

 [pro-jek´shun]
1. a throwing forward, especially the reference of impressions made on the sense organs to their proper source, so as to locate correctly the objects producing them.
2. a connection between the cerebral cortex and other parts of the nervous system or organs of special sense.
3. the condition of extending or jutting out, or a part that juts out.
4. in psychiatry, an unconscious defense mechanism whereby emotionally unacceptable traits are denied in oneself and are regarded (projected) as belonging to the external world or to someone else. It is often called the “blaming” mechanism because in using it the person seeks to place the blame for personal inadequacies upon someone else. In its extreme form projection can lead to hostility and physical attack upon others when one mistakenly perceives other persons as responsible for one's own mental anguish.
5. the orientation of a radiographic machine in relation to the body or a body part; called also view.

pro·jec·tion

(prō-jek'shŭn),
1. A pushing out; an outgrowth or protuberance.
2. The referring of a sensation to the object producing it.
3. A defense mechanism by which a repressed complex in the person is denied and conceived as belonging to someone else, as when faults that the person tends to commit are perceived in or attributed to others.
4. The conception by the consciousness of a mental occurrence belonging to the self as of external origin.
5. Localization of visual impressions in space.
6. neuroanatomy the system or systems of nerve fibers (projection fibers [TA]) by which a group of nerve cells discharges its nerve impulses ("projects") to one or more other cell groups.
7. The image of a three-dimensional object on a plane, as in a radiograph.
8. radiography standardized views of parts of the body, described by body part position, the direction of the x-ray beam through the body part, or by eponym.

projection 

1. Localization of visual impressions from the eye to the apparent source of the stimulus, such as up and to the left. This is sometimes referred to as mental projection.
2. A prominence.
3. The imaging of an object onto a screen or a surface.
erroneous projection See false projection.
false projection The false positioning in space of a visual sensation arising from a retinal image formed in an eye with paresis of an extraocular muscle. The visual sensation appears in the direction of normal action of the paretic muscle. Example: past-pointing. Syn. erroneous projection; malprojection. See past pointing.

projection,

n orthographic, a projection made on the assumption that the projection lines from the object to the plane of projection are at right angles to the plane.
projection, gnathic planes of orthographic,
n.pl the three planes of projection to which gnathologically mounted casts are oriented: the horizontal, vertical, (frontal), and profile planes. The horizontal plane is the axis-orbital plane. The hinge axis is the line of intersection for both the horizontal and frontal planes. The profile plane is the mechanical midsagittal plane of the articulator.

projection

throwing forward, e.g. x-ray projection.

somatotopical projection
an arrangement by which a picture of the body is represented on a surface, such as projection onto the cerebral cortex of the topography of the body from which the efferent nerve impulses depart or to which afferent impulses come.

Patient discussion about projection

Q. Anyone whos doctor here and is willing to help me fillin in questionare for my project? hello, my name is edward sinanta from indonesia, i am a high school student and i would like to request an interview with you for a essay regarding the trend of health problem consultation in social networking. if you don't mind to be interviewed about this issue, please notify me through this e-mail and we can discuss the details later on. thank you for your time and attention. regards, edward

A. edward, i'm not a doctor so i can't help you ,but i hope you'll find what you are looking for and way to go on finding resources for your project!!

Q. I am getting confused with my project.. I am depressed.What can i do? Soon I will be completing my French classes. As my classes are coming close I have started developing negative mind set. I don’t understand that how my classmates are doing well. I hope they do not have any stress but I am having severe stress. I am getting scared and looks like that I may fail in my classes.. I am not able to concentrate on my classes. I am getting confused with my project. My sleep has become very difficult. I too worry about the job. I am depressed. There is no support from my classmates. Please help me what shall I do?

A. You need to find a stress reliever in your life. Think of everything from going to the gym to simple interactions with others. After you have achieved a plateau of stress relief. Sit down in a non stressful place and study. Good Luck
