Internal carotid artery:
Brachiocephalic artery:
Axillary artery:
Brachial artery:
External carotid artery:
Ulnar artery:
Superficial palmar arch:
Radial artery:
Coronary artery:
The correct answer and explanation is:
Here are the correct matches:
- Internal carotid artery: Supplies the brain
- Brachiocephalic artery: Arises from the aortic arch
- Axillary artery: Is a continuation of the subclavian artery
- Brachial artery: Splits to form the radial artery and the ulnar artery
- External carotid artery: Gives rise to the occipital artery
- Ulnar artery: Travels along the medial side of the forearm
- Superficial palmar arch: Gives rise to the digital arteries
- Radial artery: Travels along the lateral side of the forearm
- Coronary artery: Arises from the ascending aorta
Explanation:
The internal carotid artery is a major blood vessel that supplies oxygenated blood to the brain. It originates from the common carotid artery and ascends into the skull to supply structures like the cerebral hemispheres and the eyes.
The brachiocephalic artery, also known as the innominate artery, is a short artery that arises from the aortic arch and quickly branches into the right subclavian and right common carotid arteries.
The axillary artery is a continuation of the subclavian artery and supplies blood to the upper limb. It passes through the axilla (armpit) and transitions into the brachial artery.
The brachial artery runs along the arm and splits into the radial and ulnar arteries at the elbow, which continue down the forearm.
The external carotid artery supplies blood to the face and scalp and gives rise to several branches, including the occipital artery.
The ulnar artery travels along the medial (inner) side of the forearm, while the radial artery runs along the lateral (outer) side. Both arteries contribute to the formation of the superficial palmar arch, which supplies blood to the hand and gives rise to digital arteries that supply the fingers.
Finally, the coronary arteries arise from the ascending aorta and supply blood to the heart muscle, ensuring it receives adequate oxygenation.
Now, let’s generate an image of the arterial system of the upper limb and head.
Here is the anatomical illustration of the human arterial system, highlighting the major arteries in the upper limb and head. Let me know if you need any modifications or additional details!
