Neurology-1.

Somatic motor impulses are responsible for :

• pain detection of different body parts

• voluntary movements of body

• voluntary movements of viscera

• pain detection of viscera

Autonomic Nervous System controls :

• Skeletal muscle, bones, skin

• muscles of glands and internal organs

• Pain detection of internal organs

• Pain detection of skin and muscles

Septum palucidum separates :

• 1st and 2nd ventricle

• third ventricle from 1st and 2nd

• third ventricle from fourth

• fourth ventricle from lateral appertures

45 years old man admitted to the hospital. CT scanning revealed Blockage of Sylvian (cerebral) aquaduct . wich changes you are able to distinguish :

• enlarged lateral ventricles

• expanded third ventricle

• expanded fourth and third ventricle

• expanded lateral and third ventricles

Which two foraminas in the fourth ventricle open into cerebellopontine cistern ?

• Lateral apertures of Luschka

• Magendie

• sylvian

• none of them

Through wich opening CSF can leave the fourth ventricle and enter subarachnoidal space ?

• Foramen magnum

• Monro foramen

• Central canal

• Magendie aperture

Communication site of CSF with venous blood ( exchange of waste products)

• Arachnoid villus

• Choroid phlexus

• Ependimal cells

• Arachnoid granullations

Lumbar Puncture must be provided at the level :

• Th10-Th12

• L1-L3

• L2-L4

• L5-S1

Patient of 6th month. enlarged skull easy to distinguish. CT scan reveals expanded ventricullar system. Your opinion :

• There is disbalance between production and absorbtion

• There is blockage caused by hematoma in third ventricle

• blockage between two lateral ventricles

• Clnical picture reveals normal production of CSF but absorbtion supposed to be increased

Semipermiable endothelial membrane, wich lines microvasculature of brain, separating blood from cerebrospinal fluid . Restricts the passage of pathogens ; diffusion of solutes in the blood, hydrophilic molecules into the cerebrospinal fluid while allowing the diffusion of hydrophobic molecules (O2, CO2, hormones) and small molecules

• CSF

• Arachnoid granullations

• Blood brain bareer

• none of them
