Antennary Arteries
originate from apex of the heart one from either of the median ophthalmic. It run s
forward along the outer border of mandibular muscle and gives out the following
branches:
a. Pericardial branch (to pericardium)
b. Gastric branch (to cardiac stomach)
c. Mandibular Branch (to mandibular muscles)
It further passes forward and divided in to
two sub-branches
a. Dorsal branch
(Send an optic artery to eye, than bend inwards and
form circulus cephalicus which gives off a pair of rostral arteries to
rostrum)
b. Ventral Branch
(it divides in sub branches, one for antennulary and
second re-divided into two and antennal artery to antenna ant other
renal artery to renal organ)

Hepatic artery
:
Paired arteries,
arise from the ventro-lateral sides of the roots
of antennary arteries. They open into hepatopancreas.
4.
Median Posterior Artery
:
I
t is small but stout
artery which arise from the
posterio-ventral surface of the heart and runs backward. It immediately bifurcate in
to two branches
a. Supra-intestinal artery (supply blood to intestine and abdominal muscle)
b. Sternal Artery ( divided into two ventral thoracic and ventral abdominal)
