|
brain lateralisation
|
the extent to which brain functions are controlled by each hemisphere of the brain
|
|
|
genes
|
➡the sections ide DNA that make people who they are
➡consists of a long strand ofq DNA, & genes are set up in such way that they are blue-print for what people are like |
|
|
hormones
|
➡chemical messengers that work more slowly than neurotransmitters & are carried in the blood stream
➡produced by endocrine system; glands in the system include pineal gland, pituitary gland and thyroid |

central nervous system
|
➡the brain (within skull) and spinal cord (within vertebrae)
➡in the embryo a tube separates into the brain and spinal cord and then there are further subdivisions ➡the brain itself is split to parts |
|
|
synapse
|
- the gap btw dendrites of one neuron and axon terminal of the other
- whether or not the neurotrabsmitter produced passes acrods the synaptic gap, the receptor waoting decides if if it can pass or if it's blocked |
|
|
receptor
|
- places on neurons on one side of the synaptic gap
- neurotransmitters that are waiting on the other side fit into receptors, and so criss the gap - if they dont fit into the receptor the uptake is blocked |
|
|
neuron
|
- a cell in nervous system that receives or passes info through electrical impulses
|
|
|
neurotransmitter
|
- chemicals in the brain that act as messengers
- either cross from one neuron to the receptor on another neuron over the synaptic gap - or dont fit into receptirs and are blocked |
