The external carotid artery (ECA) is one of the two terminal branches of the common carotid artery that has many branches that supplies the structures of the neck, face and head. The other terminal branch is the internal carotid (ICA), which is somewhat larger than the ECA, which supplies the intracranial structures.

What is the first branch of the ECA?
1. Superior thyroid artery. This artery courses to the thyroid gland.
What are the branches of the ICA?
Three Branches: Ophthalmic Artery,Posterior Communicating Artery, and Anterior Choroidal Artery. Passes through cavernous sinus with Abducens Nerve.
What is the first branch of the ICA?
Internal carotid artery Its first major branch is the ophthalmic artery. The ICA bifurcates into the anterior and middle cerebral arteries in the subarachnoid space.
Is the cavernous sinus part of the brain?
The cavernous sinus within the human head is one of the dural venous sinuses creating a cavity called the lateral sellar compartment bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica. … Cavernous sinus.

Which is the largest branch of the brachial artery?
profunda brachii artery The profunda brachii artery also referred to as the deep brachial artery, is the first and largest branch of the brachial artery. It originates from the posterior portion of the brachial artery, just inferior to the lower border of the teres major muscle.
What part of the brain does the basilar artery supply?
cerebellum The basilar artery (BA) serves as the main conduit for blood flow through the posterior circulation. It directly supplies the brainstem and cerebellum and provides distal blood flow to the thalami and medial temporal and parietal lobes.
What artery supplies blood to the brain?
internal carotid arteries The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.
What is ECA stenosis?
External carotid artery (ECA) stenosis is an independent mortality predictor. Additionally, concomitant ECA and internal carotid artery (ICA) stenosis progression has been associated with an increased risk of ipsilateral ischemic events in asymptomatic patients.
Is ECA anterior to ICA?
A few key points to keep in mind is that the ICA and internal jugular vein run together, also the ICA usually sits more posterolateral and the ECA sits more anteromedial. … In a normal patient, the ICA should have a low resistive flow pattern while the ECA has a high resistive flow pattern.
How far under the skin is the carotid artery?
23.5 +/- 6.9 mm The common carotid artery exhibited the closest average distance to the skin (23.5 +/- 6.9 mm) whereas the internal carotid artery exhibited the closest average distance to the vertebral body (7.36 +/- 3.8 mm, measured to the transverse process).
What are the 8 branches of the ECA?
The ECA is the main feeding vessel to the tissues of the head and neck region through its 8 branches, namely the superior thyroid artery (STA), ascending pharyngeal artery (APA), lingual artery (LA), facial artery (FA), occipital artery, posterior auricular artery (PAA), superficial temporal artery, and maxillary …
How do I remember ICA branches?
Mnemonics
- A: anterior choroidal artery (C7)
- V: Vidian artery (C2)
- I: inferolateral trunk (C4)
- P: posterior communicating artery (C7)
- S: superior hypophyseal artery (C6)
- C: caroticotympanic artery (C2)
- O: ophthalmic artery (C6)
- M: meningohypophyseal trunk (C4)
How can I remember the arteries of my brain?
Which side of the neck is the internal carotid artery?
Arteries of the neck. The internal carotid arteries arise from the common carotid arteries – labeled Common caroti on the figure. The internal carotid artery (Latin: arteria carotis interna) is located in the inner side of the neck in contrast to the external carotid artery.
What are the branches of the internal carotid?
Branches
- posterior communicating artery.
- anterior choroidal artery.
- anterior cerebral artery.
- middle cerebral artery.
Which artery curves backwards around midbrain?
Thus in the carotid circulation the most frequent sites are: in the internal carotid artery at its origin from the common carotid, in the stem MCA or its bifurcation into superior and inferior divisions, and in the ACA as it curves backwards over the corpus callosum.
How many cavernous sinuses are in the brain?
The two cavernous sinuses are connected to each other by anterior and posterior cavernous sinuses lying in front and behind the pituitary.
What is the cavernous sinus filled with?
venous blood The cavernous sinus (Latin: sinus cavernosus) is a large, paired channel filled with venous blood that is located against the lateral aspect of the body of the sphenoid bone on each side of the sella turcica.
Which nerve is present in cavity of cavernous sinus?
The nerves of the cavernous sinus are the oculomotor nerve (CN III), trochlear nerve (CN IV), ophthalmic nerve (V1), maxillary nerve (V2), abducens nerve (CN VI), and the sympathetic plexus around the internal carotid artery.
What side of the body is the brachial artery on?
The brachial artery is a major blood vessel located in the upper arm and is the main supplier of blood to the arm and hand. The brachial artery continues from the axillary artery at the shoulder and travels down the underside of the arm.
How do you feel the brachial pulse?
The brachial pulse can be located by feeling the bicep tendon in the area of the antecubital fossa. Move the pads of your three fingers medial (about 2 cm) from the tendon and about 2–3 cm above the antecubital fossa to locate the pulse. See Figure 3.4 for correct placement of fingers along the brachial artery.
What happens if you cut the brachial artery?
The Brachial artery runs along the inside of your arms. This artery is deep, but severing it will result in unconsciousness in as little as 15 seconds, and death in as little as 90 seconds.
What is a basilar artery stroke?
2 A basilar artery stroke occurs when blood flow to the brain is interrupted. This can happen if the vessel becomes blocked (an ischemic stroke) or ruptured (hemorrhagic stroke). The basilar artery is located at the base of the brain, where the two vertebral arteries come together.
What is the terminal branch of basilar artery?
The basilar artery terminates by splitting into the left and right posterior cerebral arteries. Pontine arteries, anterior inferior cerebellar (AICA) and superior cerebellar arteries, and terminal posterior cerebral arteries.
Where is the basilar artery formed?
vertebral arteries The basilar artery is a midline structure formed from the confluence of the vertebral arteries. Terminally, the basilar artery branches to establish the right and left posterior cerebral arteries.
What is the largest vein in the body?
Did you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.
What is the main vein that carries blood from your legs to your heart?
inferior vena cava The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
What causes narrowing of the blood vessels in the brain?
The narrowing is caused by a buildup and hardening of fatty deposits called plaque. This process is known as atherosclerosis. A stroke occurs when plaque causes the artery to become blocked and that area of the brain is deprived of blood, which damages and kills nerves in the brain.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
