Question:
Response:
Via which neural route does a pain stimulus go from the heart (e.g. angina pectoris) or lungs to the spinal cord? Put the structures in the correct order.
The figure aims to illustrate the principle of referred pain. You see nerve impulses from splanchnic nerves (the red dotted line) and nerve impulses from (the anterior or posterior ramus of) spinal nerves (the blue dotted line) converge at the same location in the spinal cord. This mechanism underlies referred pain. Which remarks regarding referred pain as depicted by this figure apply? (multiple answers can be correct)
The figure aims to illustrate the principle of referred pain with a pain stimulus led through the phrenic nerve. Which comments regarding this referred pain apply? (multiple answers can be correct)
Herpes zoster (see photo) is a very painful condition. Via what kind of nerve does the pain stimulus travel from the patient in the photo to the spinal cord?
Explain why pain from the oesophagus, eg heartburn from reflux, is sometimes difficult to distinguish from pain from the heart.
The image above can help answer this question. Fill in the missing words.
Pain in the (left) arm in cardiac ischemia can be explained by the convergence of sensory information from the heart via cardiopulmonary splanchnic nerves and the sympathetic trunk and from the arm via (anterior rami of) spinal nerves at the same spinal cord level: T6T1 / Th1. The pain from the heart is then also perceived in the arm: so-called referred pain.
