Veins of cervix
Veins correspond to the arteries and
accompany them. They are also provided with anastomoses with each other
and venoarterial passage whereby substances can diffused from vein into
artery and vice versa because of the close proximity of the two in the
reproductive tract of the female. The process is gradient
Nerves of cervix
Nerves of the cervix are from the paracervical
ganglion, (postganglionic) with one prominent
ganglion called uterine
cervical ganglion. The preganglionic fibers haved passed through

Parasympathetic fibers are
vasomotor and inhibitory from sacral outflow (S2-4).
Sympathetic fibers are from T12
They are excitatory.
