Find the incorrect match w.r.t. number of spinal nerves arising from different parts of it

Options

A. Cervical nerves -7 pairs
B. Lumbar nerves- 5 pairs
C. Sacral nerves- 5 pairs
D. Coccygeal nerves - 1 pairs

Answer

To solve the question regarding the incorrect match with respect to the number of spinal nerves arising from different parts of the spinal cord, we can follow these steps:

### Step 1: Understand the Anatomy of Spinal Nerves
Spinal nerves are categorized based on their origin from different regions of the spinal cord. There are specific numbers of pairs of spinal nerves that arise from each region: cervical, thoracic, lumbar, sacral, and coccygeal.

### Step 2: Identify the Number of Spinal Nerves in Each Region
- **Cervical Nerves**: There are 8 pairs of cervical spinal nerves (C1 to C8).
- **Thoracic Nerves**: There are 12 pairs of thoracic spinal nerves (T1 to T12).
- **Lumbar Nerves**: There are 5 pairs of lumbar spinal nerves (L1 to L5).
- **Sacral Nerves**: There are 5 pairs of sacral spinal nerves (S1 to S5).
- **Coccygeal Nerves**: There is 1 pair of coccygeal spinal nerves (Co1).

### Step 3: Analyze the Options Given
The question asks to find the incorrect match regarding the number of spinal nerves. Based on the information:
- If the option states there are 7 pairs of cervical nerves, this is incorrect because there are actually 8 pairs.

### Step 4: Conclusion
From the analysis, the incorrect match is the first option which states that there are 7 pairs of cervical nerves. The correct number is 8 pairs.

### Final Answer
The incorrect match regarding the number of spinal nerves arising from different parts of the spinal cord is the cervical nerves, which should be 8 pairs instead of 7.
