Edexcel Biology - Topic 8 - Nervous System - Flashcards in A Level and IB Biology

1. Type of summation where multiple impulses from on neurone are needed to initiate an action potential (8)
5. The type of neurone with its cell body located off the axon (7)
6. Cell which forms the myelin sheath around an axon (7, 4)
8. The part of the nervous system consisting of the brain and spinal cord (7)

2. The type of neurone with its cell body at one end (5)
3. Extensions of a nerve cell which receive impulses and conduct them towards the cell body (9)
4. Part of the autonomic nervous system that prepare the body for 'fight or flight' responses (11)
7. A synapse in which an action potential in the presynaptic membrane decreases the likelihood of an action potential in the postsynaptic membrane (10)
9. The type of neurone with its cell body within the axon (5)
10. The membrane to which synaptic vesicles bind releasing neurotransmitter into the synaptic cleft (11)
