Researchers

Question 1

Described the formation and development of volar pads on the human fetus. Found that volar pads regress at the same time friction ridges develop.

Answer 1

Harold Cummins

Question 2

Found that all mammals have the same morphological arrangement of the formation of friction ridges. Found that ridge patterns are affected by external forces and pressures by neighbouring developing ridges

Answer 2

Alfred Hale

Question 3

Described the anatomical formation of friction ridges. Established uniqueness by detailing how ridge units are subjected to differential growth

Answer 3

Inez Whipple

Question 4

Detailed the various stages of friction ridge development, particuarly how the primary and secondary ridges are formed. Detailed the developement of papillary pegs and major ridge path deviations

Answer 4

Harrison Hawthorne Wilder

Question 5

Whose extensive research of fetal skin cross sections showed the development of dermal papillae?

Answer 5

Alfred Hale

Question 6

Whose research showed the dermal papillae are in 2 rows ok the underside of the epidermis and break down as people age?

Answer 6

Michio Okajima

Question 7

Who described the evolution of the friction ridge skin of mammals including that mammals have the same arrangement of volar pads on the hands and feet?

Answer 7

Inez Whipple

Question 8

Whose extensive research on friction ridge skin showed volar pad regression occurs almost concurrently with the beginning of primary ridge development?

Answer 8

Harold Cummins

Question 9

Whose study of thin cross sections of fetal skin determined the timing and development of primary and secondary ridges?

Answer 9

Alfred Hale

Question 10

Who was the first to suggest these centers of disturbance of primate friction ridge skin formations represents the locations of the volar pads?

Answer 10

Harrison Hawthorne Wilder

Question 11

Whose extensive research of friction ridge skin showed the size, location, growth and configuration of the volar pads affect friction ridge develop and the overall fingerprint pattern?

Answer 11

Harold Cummins

Question 12

Who is credited with being the first to recognize that although specific friction ridge arrangements may be similar, they are never duplicated?

Answer 12

JCA Mayer

Question 13

Who studied incipient ridges and determined they are primary ridges that did not fully develop?

Answer 13

Michio Okajima
