early brain development Flashcards
- how the forebrain, midbrain and hindbrain develop in the foetus - the development of the cerebellum and medulla
brain
the organ in your head made up of nerves. it processes information and controls behaviour.
forebrain
the anterior part of the brain, including the hemispheres and the central brain structures.
midbrain
the middle section of the brain forming part of the central nervous system.
hindbrain
the lower part of the brain that includes the cerebellum, pons and medulla oblongata.
anterior
directed towards the front, when used in relation to our biology.
posterior
directed towards the back, when used in reaction to our biology.
cerebellum
an area of the brain near to the brainstem that controls motor movements (muscle activity).
medulla oblongata
connects the upper brain to the spinal cord and controls automatic responses (e.g sneezing, breathing, heart rate etc.)
involuntary response
a response to a stimulus that occurs without someone making a conscious choice. they are automatic, such as reflexes.
neural connections
links formed by messages passing from one nerve cell (neuron) to another.
3-4 weeks
forebrain, midbrain and hindbrain develop.
6 weeks
cerebellum starts to develop.
20 weeks
medulla begins to develop.
