The Cerebrum Flashcards
The CNS develops from a tissue called what?
Ectoderm
What is the first sign of development?
The neural plate
Describe the folding of the neural plate
The neural plate folds and becomes the neural groove and then the neural tube
What is the front of the neural tube called?
Rostal
What does the rostal develop?
The brain
What does the back part of the neural tube develop?
The spinal cord
The forebrain is also called what?
Prosencephalon
The midbrain is also called what?
Mesencephalon
The hindbrain is also called what?
Rhombencephalon

The diencephalon is what part of the brain stem?
Upper end
What are the four parts of the diencephalon?
- Thalamus
- Hypothalamus
- Epithalamus
- Subthalamus
What are the two parts of the hypothalamus?
- Amygdala
2. Hippocampus
What are the four parts of the brain stem?
- Pons
- Mindbrain
- Medulla Oblongata
- Cerebellum
What is the function of the corpus callosum?
Connects the left and right sides of the brain
What is a gyrus?
A bump in the folds of the cerebral cortex
What is a sulcus?
A groove which separates the gyri
What is a fissure?
A deeper groove
The transverse fissure divides what?
The cerebrum and the cerebellum
The longitudinal fissure divides what?
The two hemispheres of the brain
Gray matter (in the cerebral cortex), controls what?
Conscious thoughts and actions
What matter is what?
Bundles of myelin that connect gray matter areas
What is the function of myelin?
Acts as an insulator and gives what matter its color
