|
||||
|---|---|---|---|---|---|
| Neurulation | show 🗑
|
||||
| show | it gives rise to entire CNS (spinal cord, brainstem, brain).
🗑
|
||||
| Structures from Neural Crest cells | show 🗑
|
||||
| show | Meninges
🗑
|
||||
| show | The multiplying nerve cells near the center of the neural tube as it thickens.
ALAR: posterior horn (sensory). BASAL: anterior horn (motor, sends axons to myotomes).
🗑
|
||||
| show | Ventricular zone of the neural tube.
🗑
|
||||
| show | White matter tracts (axons) in the spinal cord.
🗑
|
||||
| Development of the brain and brainstem begins with what 3 primary vesicles? | show 🗑
|
||||
| Cervical flexture | show 🗑
|
||||
| Cephalic flexture | show 🗑
|
||||
| show | Prosencephalon divids into (Telencephlon and diencephalon), mesencephalon (stays the same), Rhombencephalon (divides into Metencephalon and myelencephalon)
🗑
|
||||
| After the formation of the 5 secondary vesicles from the primary 3 vesicles, where are the flextures | show 🗑
|
||||
| show | WALLS: Cerebral hemispheres. CAVITIES: lateral ventricles (seperated by the septum pellucidum).
🗑
|
||||
| show | WALLS: thalamus, hypothalamus, pineal gland. CAVITIES: third ventricle
🗑
|
||||
| Adult derivative of the Mesencephalon | show 🗑
|
||||
| show | WALLS: Pons and Cerebellum. CAVITIES: 4th ventricle
🗑
|
||||
| show | WALLS: Medulla. CAVITIES: 4th ventricle
🗑
|
||||
| show | Telencephalon. Neurons of the cerebral cortex enlarge as they proliferate. Grows from the inside out.
🗑
|
||||
| show | 1.Frontal.
2.Insular (gets overgrown by the frontal lobe).
3.Parietal.
4.Temporal.
5.Occipital.
🗑
|
||||
| Formation of CN I | show 🗑
|
||||
| show | Diencephalon which makes it part of the CNS.
🗑
|
||||
| formation of the lens | show 🗑
|
||||
| show | Retina sends axons thru R and L optic N. they reach the optic chiasm where axons swap and head towards the thalamic nuclei. From the thalamus they move to the occipital lobe
🗑
|
||||
| show | Lateral > 3rd > cerebral aqueduct > 4th > subarachnoid spcae
🗑
|
||||
| show | Stenosis of the Cerebral aqueduct (mesencephalon) will cause a back up of CSF in the 3rd and lateral ventricles.
🗑
|
||||
| show | Failure of cerebral hemispheres and lateral ventricles to seperate.
**Forms a semilobar or alobar cerebral cortex and will lead to facial development defects
🗑
|
||||
| show | disrupts occipital bone formation and causes herniation
🗑
|
||||
| show | 1.Meningocele (protruding dura and subarachnoid space).
2.Meningohyrdocephalocele (protrusion of occipital lobe)
🗑
|
||||
| show | 1.Meningoencephalocele (protrusion of cerebellum)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
