78. Blood supply of the central nervous system (I)
- Parts of the primary motor cortex that control movement of the legs are supplied by branches of the anterior cerebral artery. (T/F?)
- The recurrent artery of Heubner is a branch of the anterior cerebral artery. (T/F?)
- The anterior choroidal artery originates from the anterior cerebral artery. (T/F?)
- The Vidian artery is the artery of the pterygoid canal. (T/F?)
- The Broca’s area is supplied by the branches of the anterior cerebral artery. (T/F?)
- The primary visual cortex is supplied by branches of the posterior cerebral artery. (T/F?)
77. Circle of Willis (Gray-519)
76. Circle of Willis
- Terminal branches of the internal carotid artery are the anterior cerebral artery and the median cerebral artery. (T/F?)
- The anterior communicating artery connects the two anterior cerebral arteries. (T/F?)
- Arterial branches from the anterior communicating artery supply optic chiasm with arterial blood. (T/F?)
- The posterior communicating artery connects the middle cerebral artery and the posterior cerebral artery. (T/F?)
- The pontine arteries arise from the posterior communicating arteries. (T/F?)
- The posterior cerebral artery arises from the basilar artery. (T/F?)
75. Branches of the internal carotid artery
- Anterior choroidal artery. (T/F?)
- Anterior hypophyseal artery. (T/F?)
- Posterior hypophyseal artery. (T/F?)
- Superior hypophyseal artery. (T/F?)
- Anterior communicating artery. (T/F?)
- Posterior communicating artery. (T/F?)
74. Entry and exit points of cranial nerves, arteries and veins (I)
- Supraorbital artery: Supraorbital foramen. (T/F?)
- Ophtalmic nerve: optic canal. (T/F?)
- Mandibular nerve: foramen ovale. (T/F?)
- Middle meningeal artery: foramen spinosum. (T/F?)
- Accessory nerve: foramen ovale. (T/F?)
- Hypoglossal nerve: jugular foramen. (T/F?)
67. Vertebral artery and its branches
- The vertebral artery commonly arises from the subclavian artery. (T/F?)
- After it passes through the foramen magnum and perforates dura mater, the vertebral artery travels along the medulla oblongata, posterior to the hypoglossal nerve. (T/F?)
- It joins the vertebral artery of the opposite side at the pontomedullary sulcus to form the basilar artery. (T/F?)
- The anterior spinal artery if formed from two branches that originate from corresponding vertebral arteries. (T/F?)
- The posterior spinal artery usually originates from the anterior inferior cerebellar artery and sometimes directly from the vertebral artery. (T/F?)
- The posterior inferior cerebellar artery is the largest branch of the vertebral artery. (T/F?)
64. Cavernous sinus (Gray-571)
58. Structures that leave or enter the skull through the superior orbital fissure
- Oculomotor nerve. (T/F?)
- Trochlear nerve. (T/F?)
- Frontal nerve. (T/F?)
- Superior and inferior ophthalmic veins. (T/F?)
- Ophthalmic artery. (T/F?)
- Abducens nerve. (T/F?)
54. Wallenberg syndrome
- Lateral medullary syndrome or Wallenberg syndrome is caused by occlusion of the arteries that supply lateral medulla oblongata. (T/F?)
- It is usually caused by occlusion of posterior inferior cerebellar artery, therefor the name PICA-syndrome. (T/F?)
- The posterior inferior cerebellar artery is a branch of the basilar artery and supplies lateral parts of the medulla oblongata and parts of the cerebellum with arterial blood. (T/F?)
- The syndrome is characterized by “crossed neurological signs”, ipsilateral sensory deficits of the face and contralateral sensory deficits of the trunk and the limbs. (T/F?)
- Other signs and symptoms include vomiting, vertigo, hoarseness, dysphonia, dysphagia, decreased gag reflex, contralateral ataxia and ipsilateral Horner’s syndrome.(T/F?)
- Lateral pontine syndrome is a neurological syndrome caused by occlusion of the anterior inferior cerebellar artery (AICA) and is characterized by crossed neurological signs and symptoms but also by ipsilateral deafness and facial paresis, in difference to the PICA-syndrome. (T/F?)
