Flashcards in Neonatal Ch 25 Deck (33):
1

infant during the early newborn period

Neonate

2

the ventricle in measured at this site on the axial view; anterior, occipital, and temporal horn junction

atrium (trigone) of the lateral ventricles

3

part of the brain connecting the forebrain and spinal cord; consists of the midbrain, pons, and medulla oblongata

brain stem

4

area of the brain that forms the lateral borders of the anterior horns, anterior to the thalamus

caudate nucleus

5

prominent structure best seen in the midline filled with cerebrospinal fluid in the premature infant

cavum septum pellucidum

6

area of the brain that lies posterior to the brain stem below the tentorium

cerebellum

7

largest part of the brain consisting of two equal hemispheres

cerebrum

8

echogenic cluster of cells important in the production of cerebrospinal fluid that lies along the atrium of the lateral ventricles

choroid plexus

9

reservoir for cerebrospinal fluid

cistern

10

prominent group of nerve fibers that connect the right and left side of the brain

corpus callosum

11

echogenic fibrous structure that separates the cerebral hemispheres

falx cerebri

12

soft space between the bones

fontanelle

13

fragile periventricular tissue that bleeds easily in the premature infant; includes the caudate nucleus

germinal matrix

14

three membranes enclosing the brain and spinal cord

meninges

15

groove on the surface of the brain that separates the gyri

sulcus

16

echogenic V-shaped "tent" structure in the posterior fossa that separates the cerebellum from the cerebrum

tentorium cerebelli

17

the region at which the thalamus and caudate nucleus join

thalamic-caudate groove

18

two ovoid brian structures located midbrain, situated on either side of the third ventricle superior to the brain stem

thalamus

19

congenital blockage of the aqueduct connecting the third and forth ventricles causing dilation of the third and fourth ventricles

aqueductal stenosis

20

severe case of inadequate oxygenation

asphyxia

21

transducer is placed above the ear (above the canthomeatal line)

axial plane

22

congenital defect in which the cerebellum and brain stem are pulled toward the spinal cord (banana sign)

chiari malformation

23

transducer is perpendicular to the anterior fontanelle in the coronal axis of the head

coronal plane

24

abnormal development of the fourth ventricle; often accompanied by hydrocphalus

dandy-walker malformation

25

treatment for infants with severe respiratory failure who have not responded to conventional ventilatory support

extracorporeal membrane oxygenation

26

congenital defect characterized by abnormal single ventricular cavity with some form of thalami fusion

holoprosencephaly

27

ventriculomegaly in the neonate resulting in compression and often destruction of brain tissue

hydrocephalus

28

decreased oxygen in the body

hypoxia

29

echogenic white matter necrosis best seen in the posterior aspect of the brian or adjacent to the ventricular structure

periventricular leukomalacia

30

perpendicular to the coronal plane with the transducer in the anterior fontanelle

sagittal plane

31

site of hemorrhage for the germinal matrix; fragile area beneath the ependyma that is subject to bleeding in the premature neonate

subependyma

32

cyst that occurs at the site of a previous bleed in the germinal matrix

subependymal cyst

33

inflammation/infection of the ventricles, which appears as echogenic linear structures along the gyri

ventriculitis
