MEDIVEERSETHE PRACTICAL HUB
Locate common carotid artery on this anatomical reference. Read the original plate labels to confirm the view and adjacent structures.
Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.
head arteries: labelled anatomical figure. Original source colours and labels retained.

Carotid sinus and body
Understand what you see.
Sinus is a baroreceptor region; carotid body is a peripheral chemoreceptor.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Identify its origin or drainage
- Trace its regional course
- Confirm its important neighbouring structures
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
Examiner-style prompts: identify the structure, explain its relations, then answer the applied follow-up. These are revision questions, not authenticated past papers.
01Identify carotid sinus and body and give its main role.+
Identify its origin or drainage. Trace its regional course. Confirm its important neighbouring structures. Sinus is a baroreceptor region; carotid body is a peripheral chemoreceptor.
02Differentiate their stimuli.+
Sinus senses arterial stretch/pressure. Body responds to arterial oxygen, carbon dioxide and pH changes.
03What carries major afferents?+
Carotid sinus nerve from IX; distinguish this from a motor nerve to neck muscles.
04Point out three important relations and explain their significance.+
Sinus: arterial dilatation; Body: near bifurcation; Carotid sinus nerve from IX. Sinus is a baroreceptor region; carotid body is a peripheral chemoreceptor. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
