Sažetak
Samples of the costal and both crura of the lumbar part of diaphragm in 11 fallow deer (Dama Dama) of both sexes 1-5 years old from the National Park Brijuni (Croatia) were frozen in liquid nitrogen, cut into 10m thick slides, stained with hematoxin and eosine and pictured under 50x microscopic magnification. On so obtained photographs the diameter of 4, 138 muscle fibers was measured. Using distribution frequency of the muscle fiber diameter with the step of 5 mm, muslce fibers were classified in the groups of the same diameter. The diameters were calculated and presented tabelary to determine participation of the fibers in the function of diaphragm, with respect to their size and surface, and in the surface. Costal part and both crura comprised muscle fibers different in diameter, ranging from 10-60 mm (costal part) 10-65 mm (left crus) and 10-70 mm (right crus). All three phrenic parts contained less fibers of small diameter of up to 20 mm (14.79%, 10.67% and 12.84%), slightly more fibers of the diameter over 41 mm (22.68%, 18.37% and 15.17%), and mostly medium-sized diameter fibers, between 21-40 mm (62.53%, 70, 96% and 71.99%). Contrary to horses, cattle, lambs and pigs in which steady or labored breathing engages either costal or lumbar part of diaphragm, in fallow deer from the Brijuni biotope, these types of breathing and non-respiration engage both diaphragmatic parts simultaneously.
