Which position of the shoulder demonstrates the lesser tubercle in
profile medially? - ANSWER- Internal rotation
In which position of the shoulder is the greater tubercle seen
superimposed on the humeral head? - ANSWER- Internal rotation
Which carpals are best demonstrated by ulnar deviation/flexion? -
ANSWER- Lateral carpals, scaphoid
The long. flat structures that project posteromedially from the pedicles
are the - - ANSWER- Laminae
- ANSWER-
Where do the electrons that travel across the tube come from? -
ANSWER- Thermionic Emission
How are the electrons accelerated across the tube? - ANSWER- High
Voltage
In what direction do electrons flow across the tube? - ANSWER-
Cathode to Anode (Spinning)
How are electrons focused in the tube? - ANSWER- With focusing Cups
What happens when electrons are decelerated? - ANSWER- They give
off Photons
,How are electrons slowed down in the tube prior to emission of
photons? - ANSWER- The curve a tungsten nucleus. Bremsstrahlung
Interactions
What does Frequency determine in xray photons? - ANSWER- Energy
What are two early somatic effects of ionizing radiation? What is the
dose required for this? - ANSWER- 2 Sv
redness
hair loss
What are some late somatic effects of ionizing radiation exposure? What
dosage does occur at? - ANSWER- 5 Sv
cancer
cataracts
What is the difference between threshold and non-threshold? -
ANSWER- Threshold equals specific dose
non-threshold equals chance
What is relative biologic effectiveness? - ANSWER- The relative
capability of radiation with different LEDs to produce a particular
biologic reaction
Describe cell radiosensitivity - ANSWER- Doses of ionizing radiation
produce different degrees of damage in different kinds of human cells.
The more mature and specialized the less sensitive it is to radiation.
High reproductive rate equals highly sensitive to radiation
What is the LD 50/30 for adult humans? - ANSWER- Is the dose where
which 50% of the population dies after 30 days of exposure to high
amounts of ionizing radiation. 3 Sv
What is oxygen enhancement ratio? - ANSWER- It describes the effect
where in oxygen-rich environments, radiation does more damage.
, High linear energy transfer particles have an OER of one
low linear energy transfer particles have an OER of three (radiation dose
has to be three times higher to do the same damage without oxygen)
Late somatic effects - ANSWER- Carcinogenesis
cataractoGenesis
Acute effects of radiation - ANSWER- Erythema
epilation
desquamation
Chronic effects of radiation - ANSWER- Effects that appear within
minutes hours days weeks after high-dose exposure.
Basically nonstochastic somatic effects.
What are somatic effects? - ANSWER- They are the effects that you can
see
What are the four ARS response stages? - ANSWER- Prodromal
latent
manifest
recovery or death
Carcinogenesis - ANSWER- Occurs randomly when the body is
introduced to radiation.
