Week 1 Anatomy Terminology- Severson

Question 1

Median/sagittal Plane

Answer 1

the vertical line passing longitudinally through the body, divides the body into right and left halves

Question 2

Midsagittal planes

Answer 2

vertical planes passing through the body into EQUAL right and left halves

Question 3

Frontal/Coronal plane

Answer 3

vertical planes passing through the body at right angles to the median plane

Question 4

Transverse plane

Answer 4

horizontal planes passing through the body at right angles to the median AND frontal planes

Question 5

Flexion

Answer 5

Angle gets smaller

Question 6

Extension

Answer 6

Angle gets bigger

Question 7

Adduction

Answer 7

gets closer to the body

Question 8

Abduction

Answer 8

gets farther from the body

Question 9

lateral rotation

Answer 9

turns out (away from the body)

Question 10

medial rotation

Answer 10

turns in (toward the midline of the body)

Question 11

Parasagittal plane

Answer 11

a vertical plane that divides the body into unequal right and left halves

Question 12

Plantarflexion

Answer 12

movement of the foot at the ankle joint- extension

Question 13

Inversion

Answer 13

turning the foot so that the sole faces inward or medially

Question 14

Eversion

Answer 14

turning the foot so that the sole faces outward or laterally

Question 15

For X-ray and CAT scan which body structures are radio-lucent and which are radio-opaque?

Answer 15

Radio-lucent = air filled structures such as stomach and colon
Radio-opque= bone because of its crystalline arrangement of calcium and phosphorus

Question 16

AP projection vs. PA projections

Answer 16

anterior/posterior
posterior/anterior

X-ray image is less distorted for that portion of the body closer to the X-ray detector. The farther away the tissue is from the X-ray detector, the larger it appears

Question 17

Conventional Radiography

Answer 17

directing x-rays to one part of the body and detecting the radiation that emerges on the other side, radiation emerging varies due to density and the way the material can absorb and scatter x-rays

Question 18

Computer assisted tomorgraphy (CT)

Answer 18

multiple x-ray images of the body are rapidly performed

computer analyzes the detectors repsonse to produce the image in a plane

more details than x-ray, but still harmful

Question 19

MRI

Answer 19

uses magnetic fields to produce images.
Patient places in magnetic field and pulse with radiofrequency waves, causes nuclei of atoms to emit a radiosignal that can be detected

Produces better images of soft tissue, free from damaging side effects but expensive
