A famous tag-team wrestler has a famous "sleeper hold" that he uses on his opponents. Using only a single digit on each hand, he presses on his opponent's neck until his opponent passes out. What are the structures on which he is pressing and what is the effect?
A) Subclavian arteries; blood flow to brain is stopped
B) Carotid chemoreceptors; blood pressure increases
C) Baroreceptors in carotid sinus; peripheral vasodilation and decreased heart rate
D) Vertebral arteries; blood flow to brain is increased
E) Jugular vein; blood flow back to heart is decreased
Carotid Chemoreceptors
Sensory receptors located in the carotid arteries that detect changes in blood oxygen levels, helping regulate breathing.
Baroreceptors
Sensory nerve endings located in the walls of blood vessels that detect changes in blood pressure and help regulate it.
