Q

Where does Atherosclerosis typically occur in the Carotid Artery?

A
  • Bifurcation is a common site for atherosclerosis
  • This causes the artery to narrow
  • The plaque can rupture and release an embolus which can travel to the brain
  • Causing a TIA/ Stroke

Q

What is the Carotid Sinus Massage?

A
  • Applying pressure on the carotid bodies
  • This increase the baroreceptor activity and causes the heart to slow down

  • Anterior Cerebral Artery
  • Middle Cerebral Artery
  • Posterior Communicating Artery
17
Q

What are the branches of the Ophthalmic Artery?

A
  • Lacrimal Artery
  • Central Retinal Artery
  • Supratrochlear Artery
  • Supraorbital Artery
18
Q

What are the branches of the External Carotid Artery?

A
  • Some Anatomists Like Freaking Out Medical Students
  • Superior Thyroid
  • Ascending Pharyngeal
  • Lingual
  • Facial
  • Occipital
  • Posterior Auricular
  • Maxillary
  • Superficial Temporal
19
Q

What is the blood supply to the scalp- Internal and External?

A
  • Internal ( Supraorbital artery/ Supratrochlear artery)
  • External ( Superficial Temporal artery/ Posterior Auricular Artery/ Occipital Artery)
20
Q

What are the layers of the scalp?

A
  • Skin
  • Connective Tissue
  • Aponeurosis
  • Loose Areolar Tissue
  • Periosteum
  • Bone
21
Q

Why does the scalp bleed?

A
  • Heavy bleeding is seen in scalp injures
  • Artery walls are help open by connective tissue and therefore can’t constrict
  • Lots of anastomoses
22
Q

What are the Superficial arteries of the face?

A
  • Facial Artery:
    1. Superior and Inferior Labial Artery
    2. Lateral Nasal Artery
    3. Angular Artery
  • Maxillary Artery:
    1. Transverse facial artery
  • Supraorbital and Supratrochlear Arteries
23
Q

What does your Maxillary Artery Split into?

A
  • Middle Meningeal Artery
  • Sphenopalatine Artery
24
Q

How does the Middle Meningeal Artery enter the skull?

A
  • Foramen Spinosum
25
Q

What does the Middle Meningeal Artery split into?

A
  • Anterior and Posterior Middle Meningeal Artery
26
Q

What does the Anterior Meningeal artery pass under?

A
  • Pterion
27
Q

What can causes an extradural haemorrhage?

A
  • Damage to the Pterion and therefore damage to the anterior meningeal artery
28
Q

What is the management of an extradural haemorrhage?

A
  • Craniotomy - opening of the cranium to relieve the pressure
  • Evacuate the clot forming and stop the bleeding
29
Q

What imaging modality allows you to visualise an extradural bleed?

A
  • Transverse CT image of brain
  • Lunar picture
30
Q

What is the drainage of the scalp?

A
  • Brain Structures drain into the dural venous sinus
  • The scalp drains via emissary veins through the skull into the dural venous sinus
31
Q

What vessels drain into the Internal Jugular Vein?

A
  1. Supra-orbital Vein
  2. Supratrochlear Vein
  3. Angular Vein
  4. Deep Facial Vein
  5. Common Facial Vein
  6. Facial Vein
  7. Superficial Temporal
  8. Retromandibular Vein
  9. Cavernous Sinus
  10. Internal Jugular Vein
32
Q

What facial Veins Drain into the Cavernous Sinus?

A
  1. Superior Ophthalmic Vein
  2. Inferior Ophthalmic Vein
  3. Facial Vein
  4. Pterygoid Venous Plexus
  5. Cavernous Sinus
33
Q

What are the Dural Venous Sinuses?

A
  1. Superior Sagittal Sinus
  2. Inferior Sagittal Sinus
  3. Sigmoid Sinus
  4. Transverse Sinus
  5. Cavernous Sinus
