Referred pain may be perceived at some distance from the area of tissue injury, but generally felt a. with slightly less intensity. b. within 10 to 15 cm area. c. within the same dermatome. d. on the same side of the body.

c. within the same dermatome.

Explanation:

Referred pain is pain experienced on a surface area distant from the stimulated organ. Often, the area where the pain is manifested and the related visceral organ has the same spinal cord innervation, which suggests an explanation for this phenomenon.

With the referred pain it is possible for an internal organ to suffer some kind of irritation and this pain is not felt in this organ itself, but in a somatic structure distant from it (somatic pain). When this happens the pain is felt within the same dermatome, which is a skin area with stimuli provided by the cutaneous branches of a single spinal nerve.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
