Veins

Front 1

superior vena cava/ inferior vena cava

Back 1

Two major vessels which empty into the right atrium

Front 2

lymph

Back 2

A fluid that is composed of plasma minus certain macroproteins. It enters a network of lymph capillaries and is moved from there into larger lymph ducts, eventually also draining into the subclavian veins.

Front 3

Lymph nodes

Back 3

are small, oval bodies composed of reticular tissue which is adapted specifically to filter lymph. They usually occur in clusters in specific regions of the body.

Front 4

Germinal centers

Back 4

inside the node and are the sites of lymphocyte production.

Front 5

The most common types of nodes

Back 5

popliteal and inguinal (which means pertaining to the groin) nodes, the lumbar nodes (in the pelvic region), cubital and axillary nodes (the upper extremity), and the cervical nodes.

neck

Front 15

internal jugular

Back 15

Extremely important to the venous system because all blood from the brain and deep areas of the face and neck are drained into it. There are two jugular veins, and they pass down the neck beside the common carotid arteries. They empty into the subclavian veins.

Front 16

brachiocephalic

Back 16

Also called innominate veins.

Front 17

innominate

Back 17

Where the subclavian and internal jugular veins come together. There are two of these, and they merge together to form the superior vena cava.

Front 18

external jugular

Back 18

The blood from the top of the head, part of the face, and the superficial neck region drain into these veins. They also empty into the subclavian veins.

Front 19

diploic

Back 19

There are several diploic veins, including the frontal diploic vein, occipital diploic vein, anterior temporal diploic vein, and posterior temporal diploic vein. These comprise the veins of the skull.

Front 20

supratrochlear

Back 20

These two veins begin high in the forehead and descend to the root of the nose.

Front 21

retromandibular

Back 21

Formed in the parotid gland by a union of the maxillary vein and the superficial temporal vein. It literally means behind the mandible.

Front 22

basilic

Back 22

A major superficial vein of the upper extremity. It passes on the ulnar side of the forearm and eventually forms the axillary vein.

Front 23

cephalic

Back 23

In addition to the cephalic vein, there are accessory cephalic and median cephalic veins. The cephalic vein is the other main superficial vein of the arm.

Front 24

median cubital

Back 24

A large branch of the cephalic vein which goes over the cubital fossa and joins with the basilic vein.

Front 25

median antebrachial

Back 25

Arises from the palmar venous plexus and passes up the forearm.

Front 26

plexus

Back 26

The term plexus means literally a network or tangle. It is a general term for a network of lymphatic vessels, nerves, or veins.

Front 27

azygos

Back 27

In addition to the azygos vein, there is a left azygos and a lesser superior azygos vein. The azygos vein extends superiorly along the abdominal and thoracic walls on the right side of the vertebral column. At the level of T4 it joins directly with the superior vena cava.

Front 28

hemiazygos

Back 28

This is a tributary of the azygos vein.

Front 29

saphenous

Back 29

The small saphenous and the great saphenous veins are the superficial veins of the lower extremity. They are also called the greater saphenous and lesser saphenous veins. The greater saphenous is the longest vein of the body and is often harvested to repair vessels of the heart.
