theroranic
circuit (Pain)
- Dorsal Column
Circuit (pressure
& touch
- Cross over into

sensory cortex
- Afferent neurons
- Brain
- Formation
- Prosencephalon
(Forebrain)
- Telencephalon
- cerebral hemisphers
- Diencephalon
- Thalamus, optic nerve, hypothalamus
- Mesencephalon
(Midbrain)
- Mesencephalon
- tectum

- Main Parts
- Cerebrum
- Frontal lobe
- Functions: concentration,
problem solving, planning,
intellect, learning
- Temporal lobe
- Functions: memory,
hearing, language and
music comprehension
- parietal lobe
- Functions: visual and
spatial perceptions, touch
- occipital lobe
- Functions: vision, recognition
of printed words
- Cerebellum
- Functions: coordination,
balance, equilibrium

- Neurulation
- Neural plate
- Neural tube
Anmerkungen:
- guided down the back side of the body by the notochord
- Neural Crest Cells
- Migratory
- Melanocytes
- Adrenal medula
Anmerkungen:
- Some Neural crest cells get trapped in mesoderm. It creates the adrenal medusa which produces epinephrine.
- Neural Tube Defect
Anmerkungen:
- Annotate the neural tube defects based on their location.
- Notocord
- Differentiation
Anmerkungen:
- change in physical and functional properties of cells as they proliferate to form different structures and organs.
- cranial end
- caudal end
