it is triangular in shape in sagittal section
it continuous below with the subarachnoid space of the spinal cord
It continuous with the fourth ventricle through the foramen Magendie
Correct statements about the frontal lobe include :
it receives the input from the thalamus
it is important for spatial processing of afferent information
the following statements concerning the corpus callosum are correct:
it connects the cerebral hemispheres
the body of the corpus callosum is a floor of the great longitudinal fissure
it is covered by indusium griseum
Correct statements about the pyramid include:
it lies between the median fissure and the anterolateral sulcus
at its rostral end, at the junction with the pons, the N. VI emerges
it contain corticospinal fibers
its does not contain contalateral corticospinal fiber
the following statements concerning the cerebrospinal fluid is correct:
It is produced by choroid plexuses
It passes through the ventricular system
It enters the subarachnoid space through the foramina of Magendie
About 330-380 ml of cerebrospinal fluid enters the venous drainage per day
passes between subarachnoid space and superior sagittal sinus
The arachnoid villi allow cerebrospinal fluid to pass between subarachnoid space and superior sagittal sinus
Correct statements about the middle cerebral artery cistern include:
It has two segments
The first segment is found in the Sylvian sulcus

the following statements concerning the anterior cerebral artery are true ;
It is the terminal branch of the internal carotid artery
It supplies the upper part of the precentral gyrus
It branches over the medial surface of the hemisphere
it has two segment
the Posterior cerebral artery supplie occipital lobe
Correct statements about the spinal cord include:
Its gray matter is divided into three cell columns on each side
Substantia gelatinosa is found at all levels
It lies within the subarachnoid space
Correct statements about the prefrontal cortex include which:
It is important for spatial processing of afferent information
Correct statements about the lateral corticospinal tract include:
it is concerned with voluntary skilled motor activity
it arises from lamina IV of the cerebral cortex

. It controls the precise movements of the hand
It includes lateral zone of cerebellum
the following statements concerning the corticobulbar system is correct:
The motor neurons that innervate the genioglossus muscle receive primarly contralateral input
Corticobulbar fibers in crura cerebri are located medial to the corticospinal fibers
They pass through the genu of the internal capsule
correct statment principal sensory nucleus:
its lateral to motor nucleus of trigerminal nerve
its found in pons
it recieve descriminative tactile adn pressure sensation input from face
correct about ventro postroateral thalamic nucleus:
it recieve spinothalamic track and medial lemniscus
facial colliculus it blongs to pons
correct statment about midbrain:
substantia nigara ceprate crura cerebri from tegmental part
it contain occulumotor nucleus and trochlear nucleus
accessory nucleus of midbrain control sphincter papillary muscles of iris
