In the highlighted area, what pulse could be measured?
Radial
Ulnar
Brachial
Dorsalis pedis
The Correct Answer is A
A. Radial: The radial pulse is palpated at the lateral (thumb) side of the wrist between the tendons of the flexor carpi radialis and the abductor pollicis longus -it is superficial and commonly used clinically, so this is the correct pulse for a wrist/forearm highlighted area.
B. Ulnar: The ulnar pulse lies on the medial (pinky) side of the wrist and is deeper and often harder to palpate than the radial; it would not be the best choice if the highlighted area is lateral at the thumb side.
C. Brachial: The brachial pulse is felt on the medial aspect of the arm (at the antecubital fossa or just medial to the biceps tendon) and is used for infants or blood pressure -it is not located at the distal wrist.
D. Dorsalis pedis: The dorsalis pedis pulse is on the dorsum of the foot (between the tendons over the instep) and is unrelated to a wrist/forearm highlighting.

Correct Answer is A
Explanation
A. To produce antibody molecules: plasma cells are differentiated B cells specialized for synthesizing and secreting antibodies.
B. To directly attack cells displaying antigens: cytotoxic T lymphocytes (and NK cells) directly attack antigen-bearing cells; plasma cells primarily secrete antibodies.
C. To increase the volume of the blood plasma: plasma cell activity does not change plasma volume; they produce proteins (antibodies), not fluid volume.
D. To produce interferon: many cell types secrete interferons in response to viral infection (e.g., infected cells, immune cells), but plasma cells are dedicated antibody producers.
