31
pulsation of the internal carotid can be palpated where?
immediately lateral to larynx
32
what does the internal carotid supply

34
When common carotid bifurcates there is a swelling called _____
carotid sinus
35
what is located in the carotid sinus for homeostasis
baroreceptors
36
when baroreceptors in carotid sinus detect a change in b/p where is the visceral sensory information sent along and where to
Glossopharyngeal nerve to CNS
37
what does the subclavian artery supply
Upper limbs, thorax, neck region, brain
38

51
The head and neck are richly innervated with ________ nerves
sympathetic
52
A patient may develop hypocalcaemia after thyroid surgery - why?
parathyroid glands may be removed, which disturbs calcium homeostasis resulting in hypoparathyroidism
