The GNAQ protein levels in the caput and cauda epididymis were significantly greater than those observed in the corpus epididymis
(p<0.01) and testis (p<0.05) (Figure 4B).
It covers the superior pole of the testis and connects by a narrow corpus epididymis
to a prominent cauda epididymis projecting from the distal border of the testis.
In one study, testicular atrophy and separation of the caput and caudal regions with a loss of corpus epididymis
was observed in two rats, which were excluded from the analysis (Ohsako et al.
The incisions of the caput and corpus epididymis
were flushed with 2-3 drops of 2.9% buffered sodium citrate kept at body temperature.
The epididymis is separated into 4 different regions, initial segment (IS), caput epididymis, corpus epididymis
, and caudal epididymis, depending upon their histological and functional characteristics (Figure 3A) (Ilio and Hess, 1994).
The incisions of the caput and corpus epididymis flushed with 2-3 drops of 2.9% buffered sodium citrate kept at body temperature.
There were higher values (p<0.05) of proximal and distal cytoplasmic droplets in carput and corpus epididymis, when compared with the same values in the caudal epididymis.
The corpus epididymis
showed very low numbers (about 0.12/1000-0.22/1000) in both young and old males.
