Is there a Thyrocervical trunk on both sides?
It is located distally to the vertebral artery and proximally to the costocervical trunk….

Is costocervical trunk the same as Thyrocervical trunk?
The costocervical trunk is a short artery that usually stems from the upper portion of the distal segment of the subclavian artery, distal to the thyrocervical trunk. It courses posteriorly, over the apex of the lung, where it divides into two terminal branches; supreme intercostal and deep cervical arteries.
What is the function of Thyrocervical trunk?
Primarily, the thyrocervical trunk is tasked with supplying oxygenated blood to the viscera of the neck, which includes the thyroid and parathyroid glands, the trachea and larynx, as well as the pharynx and esophagus in the throat.
Where is the lingual artery?
The lingual artery passes between the middle constrictor of the pharynx and the hyoglossus muscles.  At the anterior border of the hyoglossus muscle, the lingual artery ascends to the tip of the tongue.
What is subclavian steal syndrome?
“Subclavian steal” refers to a syndrome of symptoms relating to arterial insufficiency in a branch of the subclavian artery stemming from flow reversal, attributable to occlusive disease in the subclavian artery proximal to that branch that is usually atherosclerotic in cause.
Where is the Costocervical trunk?
The costocervical trunk is an artery that supplies blood to the head and neck. A paired vessel that appears on both sides of the neck, this artery is a branch of the subclavian artery in the shoulder which delivers blood to the upper extremities.
Where does the Costocervical trunk arise from?
It arises from the posterior wall of the subclavian artery, posterior or medial to the anterior scalene muscle and courses posterosuperiorly across the suprapleural membrane where it divides into 2 branches: the superior (supreme) intercostal artery which supplies the first two posterior intercostal spaces.
Where is the axillary pulse?
In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery….
What does deep cervical artery supply?
The deep branch, which is the dorsal scapular artery, supplies blood to the levator scapulae muscle, the rhomboid muscles, and part of the trapezius muscle, which are superficial muscles of the upper back.
What is the carotid triangle?
The carotid triangle includes the common carotid artery and its bifurcation into the external carotid artery (ECA) and internal carotid artery (ICA). It usually contains the superior thyroid, lingual, facial, occipital, and ascending pharyngeal arteries.
What does the Costocervical trunk supply?
The costocervical trunk is a branch of the subclavian artery which supplies the upper extremities and contributes partly to the blood supply of the head and neck. The subclavian artery has a different origin on each side.
What does the thyrocervical trunk supply?
The thyrocervical trunk is one of the 3 branches of the first part of the subclavian artery and gives off numerous branches to supply viscera of the neck, the brachial plexus, neck muscles and the scapular anastomosis. It ascends medial and posterior to the lower pole of the thyroid gland superficial to the pretracheal fascia.
Can a thoracic artery arise from a thyrocervical artery?
In about 10% of people, the internal thoracic artery can also arise from this trunk. The branches of the thyrocervical trunk show a significant amount of variability in terms of their origin, number or course. The inferior thyroid artery can be absent or can have an accessory vessel on each side.
What is the trunk of the thyroid?
The trunk arises lateral to the vertebral artery from the anterosuperior wall of the subclavian artery adjacent to the anterior scalene muscle in the lower anterior neck and ascends as a short, stout trunk before giving rise to four branches: (see mnenomic) the inferior thyroid artery is the largest and most important branch of the trunk.
What are the branches of the cervical trunk?
The branches arising from this trunk are extremely variable. It can have up to five branches, but most commonly described are the inferior thyroid, suprascapular, ascending cervical and transverse cervical arteries. This arterial trunk has a wide supply territory.
