26
What parts of the brian does the vertebro-basilar system supply?
Brainstem Cerebelleum Thalamus Occipital lobe
27

Posterior cerebral artery
28

Basilar artery
36
What is I?
Anterior inferior cerebellar artery
37
What is J?
Vertebral artery
38
What is K?
Posterior inferior cerebellar artery
39
What cranial nerve emerges just above the superior cerebellar artery?
Occulomotor
40
What are the different aspects of nerve supply to the arteries in the brain?
**Carotid sinus** - dilation located in terminal part of CCA, is pressure sensitive receptor which monitors blood to the head, sensory nerves from carotid sinus run in the glossopharyngeal nerve and vagus nerve **Carotid body** - area in posterior wall of terminal part of CCA, contains chemoreceptors which are sensitive to low oxygen levels, sensory nerves from these receptors run in the glossopharygeal nerve **Sympathetic motor nerves** - from superior cervical ganglion form plexus around ICA, enters skull through carotid canal and continues along main branches of ICA
41
Where is the carotid sinus?
Terminal part of CCA (or proximal part of ICA)
42
What does the carotid sinus respond to?
It is a pressure receptor that monitors blood flow to the head and brain
43
Sensory nerves from the carotid sinus run with what nerve(s)?
Glossopharyngeal Vagus
44
The carotid body is located where?
Posterior wall of the terminal part of the common carotid artery in the neck
45
The carotid body responds to what?
Contains chemoreceptors which are sensitive to low oxygen levels, causing: increased heart rate, increased respiration rate, increased blood pressure
46
Sensory nerves from the carotid body run in what nerve(s) ?
Glossopharyngeal nerve
47
The plexus formed from sympathetic motor nerves from the superior cervical ganglion enter the skull through what?
Carotid canal
