What is the inferolateral?
Inferolateral: Below and to one side. Both inferior and lateral. In anatomy, there are many such compound terms.
What are the three branches of the internal carotid artery?
Three Branches: Ophthalmic Artery, Posterior Communicating Artery, and Anterior Choroidal Artery. Passes through cavernous sinus with Abducens Nerve.
How do you remember the internal carotid artery?
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)
What is Inferolateral trunk?
The inferolateral trunk (ILT) of the internal carotid artery (ICA) is a branch that arises inferiorly from the C4 segment of the cavernous ICA. It provides blood supply to the 3rd, 4th, and 6th cranial nerves, as well as to the gasserian ganglion.
What are the Inferolateral leads?
Inferolateral STEMI: There is ST elevation in the inferior (II, III, aVF) and lateral (I, V5-6) leads. The precordial ST elevation extends out as far as V4, however the maximal STE is in V6. ST depression in V1-3 is suggestive of associated posterior infarction (the R/S ratio > 1 in V2 is consistent with this).
What does internal carotid supply?
The internal carotid artery supplies blood to the brain. The external carotid artery supplies blood to the face and neck.
What do the internal carotid arteries supply?
The internal carotid artery, being one of the most clinically relevant and vital arteries, supplies oxygenated blood to crucial structures such as the brain and eyes.
What does the common carotid artery supply?
The Common Carotid artery is a large elastic artery which provides the main blood supply to the head and neck. The carotid arteries are the primary vessels supplying blood to the brain and face.
What is the median eminence?
The median eminence at the base of the hypothalamus serves as an interface between the neural and peripheral endocrine systems. It releases hypothalamic-releasing hormones into the portal capillary bed for transport to the anterior pituitary, which provides further signals to target endocrine systems.
Where is the superior hypophyseal artery located?
The superior hypophyseal artery (or arteries) is a branch from the C6 segment of the internal carotid artery. It is usually a single trunk arising from the medial or posteromedial aspect of the internal carotid artery within 5 mm of the origin of the ophthalmic artery 2.
