Resumo
The aim of this study was to describe the
morphology and biometry of the apical ligament of the penis
of Girolando bulls. For this purpose, it was dissected 32 penis
of Girolando bulls obtained from slaughterhouses and kept
frozen until their dissection. The animals were 36 to 48 month
old and weighted between 480 and 540kg. The origin of the
apical ligament occurred at 15.1±2.9cm distally to the caudal
loop of the sigmoid flexure and its insertion occurred at
1.4±0.7cm proximally to the neck of the glans. The length of
the apical ligament was 19.9±2.6cm. The width was 1.9±0.6mm
at its origin, 2.2±0.8mm at its insertion and 35.2±10mm at the
insertion of the internal lamina of prepuce. The average
thickness along its extension varied from 0.7 to 1.0mm. On the
free portion of the penis the apical ligament involved
predominantly the dorsum and the left side of the penis, and its
attachment to the tunica albuginea varied along its extension.
The apical ligament is firmly attached to the tunica albuginea
on its origin, insertion and on the left side of the penis, but
dorsally and on the right side of the penis this union is made
only through loose connective tissue. Significant linear relation
was observed between length and circumference of the penis
with length of the apical ligament, but the relation between
these penis parameters and the width of the apical ligament
was low.
