Flashcards in gross brain lab Deck (24):
1

1. Identify the circle of Willis as well as the major vessels leaving it

Haines 2-18 and 2-21

2

Which areas of the brain are irrigated by the anterior cerebral artery

Medial regions of frontal and parietal lobes

3

Which areas of the brain are irrigated by the middle cerebral artery

lateral regions of frontal, parietal and temporal lobes

4

Which areas of the brain are irrigated by the posterior cerebral artery

medial regions of occipital and temporal lobes plus lateral occipital lobe

5

3. Understand the venous drainage through the superior sagittal sinus and transverse sinus

superior sagittal sinus > confluence of sinuses > transverse sinus > sigmoid sinus > internal jugular vein

6

4. Identify these blood vessels on cerebral angiograms

chapter 10

7

5. Identify the major structural features of the Brain’s Lateral surface: central and lateral sulci, precentral and postcentral gyri, frontal lobe, parietal lobe, temporal lobe, parietooccipital sulcus

Chapter 2 (2-11, 2-5)

8

Where is the primary motor and somatosensory cortex

Primary motor cortex: cortex in the pre-central gyrus (contains cell bodies of upper motor neurons that control muscles). Primary somatosensory cortex: cortex in the postcentral gyrus (receives touch, vibration and proprioception info)

9

6. Identify the major structural features of the Brain’s ventral surface: Olfactory bulb, Gyrus rectus, Uncus, Optic nerve, Optic chiasm, Optic tract
6. Identify the major structural features of the Brain’s ventral surface: Olfactory bulb, Gyrus rectus, Uncus, Optic nerve, Optic chiasm, Optic tract

2-14, 2-17, 2-20

10

What is the uncus

protrusion made by the underlying amygdala

11

7. Identify the major structural features of the Brain’s medial (hemisected) surface: cingulate gyrus, calcarine sulcus, parietooccipital sulcus, corpus collosum (genu, body, splenium), anterior comissure, fornix, hypothalamus, thalamus, pineal gland, superior colliculus, inferior colliculus

2-26, 2-29, 2-30

12

What is cingulate gyrus

part of limbic system

13

what is calcarine sulcus

where primary visual cortex is located

14

corpus collosum

carries axons that connect one hemisphere with the other

15

the anterior comissure

carries axons that connect the temporal lobe on one side with its counterpart on the other

16

fornix

an axon tract involved in the limbic system involved in memory formation and retrieval carrying information
from hippocampus to hypothalamusan axon tract involved in the limbic system involved in memory formation and retrieval carrying information
from hippocampus to hypothalamus

17

hypothalamus

involved in regulation of homeostasis

18

thalamus

where all sensory systems (except for olfaction) relay information on the way to cortex

19

function of superior and inferior colliculus

superior colliculus is involved in coordinating auditory and visual maps of space; the inferior colliculus is part of the auditory system.

20

8. Identify the cerebellar hemispheres, vermis, anterior and posterior lobes, flocculus and nodulus

2-37, 2-38

21

9. Identify the lateral, third, and fourth ventricles, the foramina of Munro, Magendie, and Luschka, interventricular foramen, cerebral aqueduct, cisterna magna, interpeduncular cistern

4-6, 4-10, 4-11

22

10. Locate the cisterna magna and interpeduncular cistern Describe the path of CSF flow through the ventricles into subarachnoid space. What happens if there is an obstruction to CSF flow?

Choroid plexus > lateral ventricle > interventricular foramen > third ventricle > cerebral aquaduct > fourth ventricle > foramen of luschka > subarachnoid space. Hydrocephalus

23

On cross section, identify: Lateral ventricle and its parts (anterior horn, posterior horn, inferior horn), Superior, middle and inferior temporal gyri, Cingulate, occipitotemporal and parahippocampal gyri, Insula, Hippocampus, Fornix, Corpus callosum (and its parts)

ch 5

24

On cross section, identify: Anterior commissure, Amygdala, Lenticular nucleus, and its two parts, the putamen and globus pallidus, Caudate nucleus, Thalamus and hypothalamus, Anterior and posterior limbs of the internal capsule, Third ventricle, Medulla, Pons, Midbrain
