MICROANATOMY

Detailed explanation-1: -The anterior jugular vein is a related vein that is formed from submandibular veins and can drain into the external jugular vein or the subclavian vein directly, with the latter being more common. [2] The external jugular vein most commonly drains into the subclavian vein near the middle third of the clavicle.

Detailed explanation-2: -What are the jugular veins? The jugular veins are major blood vessels that stretch from your head to your upper chest. Typically, there are three pairs of jugular veins-six in total-each of which directs blood from different areas of your head toward your heart.

Detailed explanation-3: -The brain is a tremendously well-perfused organ, receiving up to 20% of the resting cardiac output. This blood flow reaches the brain via the internal carotid arteries and the vertebral arteries and ultimately gets drained by the internal jugular veins.

Detailed explanation-4: -jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava. The main vessels are the external jugular vein and the interior jugular vein.

Detailed explanation-5: -It descends obliquely along the neck, superficial to the sternocleidomastoid muscle. Upon reaching the clavicle, it crosses the deep cervical fascia and ends by draining into the subclavian vein. The main function of the external jugular vein is to drain the superficial structures of the head, i.e. the scalp and face.
