Name the 5 vesicles developed from neural tube closure caudal to rostral & their contents.
What part of the neural tube becomes the ventricular system? |
1)Rhombencephalon(Hindbrain)=>Myelencephalon(Medula) & Metencephalon(Pons & Cerebellum)
2)Mesencephalon(Midbrain) 3)Prosencephalon(Forebrain)=> Diencephalon(Thalmus, Hypothalamus, Retina) & Telencephalon (Cerebral Cortex, Basal Ganglia, Olfactory Bulb) The neural canal |
|
What components make up the brain stem?
|
Medulla, Pons, & Midbrain
|
|
Name the pathway of CSF production & flow.
|
Choroid plexus=>Lateral ventricles=>Interventricular foramen=>III ventricle=>Cerebral Aqueduct=>IV ventricle=>Lateral or Median aperture=>subarachnoid space=>arachnoid granulations=>Dural venous sinus(superior sagittal sinus) =>CSF empties directly into the venous system
|
|
Name the areas of the brain associated with the following ventricles:
1) Lateral ventricles 2) Third ventricle 3) Cerebral aqueduct 4) Fourth ventricle |
1) Cerebral hemispheres
2) Thalamus & Hypothalamus 3) Midbrain (mesencephalon) 4) Pons, Medulla, & Cerebellum |
|
What is a Cistern?
What are the communications between ventricles & subarachnoid space in the medulla? |
Pools of CSF
Lateral Aperture = Foramen of Lushka Median Aperture = Foramen of Magendie |
|
Name the different types of obstructions in CSF flow.
What clinical problem results? |
Non-communicating: block in ventricular system
Communicating: block in subarachnoid space or granulations Produce hydrocephalus |
|
Name the coverings of the brain from exterior to interior.
|
Dura mater(brain & spinal cord)=>Arachnoid mater=>Pia mater
|
|
Name the spaces in the Meninges, which structures blood fills between, & the common vessels to be ruptured.
|
Epidural space: Blood fills between skull & dura (Middle meningial artery)
Subdural space: Blood fills between dura & arachnoid mater (Bridging veins) Subarachnoid space:Blood fills between arachnoid & pia mater (Middle cerebral artery) |
|
Histology of Nervous system
What are the ER of neurons called in a special stain? What structure produces CSF? Which cells line the ventricles? |
Nissl bodies
Choroid plexus Ependymal cells |
