venous plexus

Batson's venous plexus may also allow the spread of infection in a similar manner.

A venous plexus is a congregation of multiple veins.

The Suboccipital Venous Plexus drains the back of the head.

As a result, an infection of the face may spread to the cavernous sinus and pterygoid venous plexus.

The median antebrachial vein drains the venous plexus on the volar surface of the hand.

It communicates with the anterior vertebral venous plexus.

The posterior scrotal veins are veins which drain into the vesical venous plexus.

A free communication between the portal and systemic venous systems is established through the rectal venous plexus.

Haemorrhoids occur due to prolapse of the rectal venous plexus and are no more common in patients with portal hypertension than those without.

They drain into a venous plexus which is situated over the thenar and hypothenar eminences and across the front of the wrist.

The CSF is then absorbed into the spinal epidural venous plexus or soft tissues around the spine.

The external vertebral venous plexuses is also available for the internal vertebral venous plexus to communicate with.

The prostatic venous plexus connects with vertebral veins, this is thought to be the route of bone metastasis of prostate cancer.

In the spine, the epidural space contains loose fatty tissue, and the epidural venous plexus, a network of large, thin-walled veins.

The anterior facial vein receives a branch of considerable size, the deep facial vein, from the pterygoid venous plexus.

The subcutaneous venous plexus that plays a major role in the conduction of heat and contains a major fraction of the cutaneous blood volume.

These beta-adrenoceptors could exert a dilator mechanism on the above-described basal tone of the facial cutaneous venous plexus.

If the pulse oximeter is attached without compressing the skin, a pressure pulse can also be seen from the venous plexus, as a small secondary peak.

The vesical veins receive blood from the vesical venous plexus and are tributaries of the internal iliac veins.

Hematogenous spread, or spread through blood vessels, occur either through the venous plexus of Batson or by arterial dissemination.

Between the lacrimal sac and the fascia coverning the sac there is the collection of venous plexus present hence the incising causes considerable bleeding.

S. haematobium schistosomula ultimately migrate from the liver to the perivesical venous plexus of the bladder, ureters, and kidneys through the hemorrhoidal plexus.

The epidural venous plexus is a network of interconnecting veins located in the anterior epidural space, in the outermost part of the spinal canal.

The frontal vein (supratrochlear vein) begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein.

Through the condylar canal, the occipital emissary vein connects to the venous system including the suboccipital venous plexus, occipital sinus and sigmoid sinus.
