|
Neuron |
Individual nerve cell that is specialised to receive, process or transmit info (to other neurons, muscles and glands) |
|
|
Dendrites |
Detects and receives info from other neurons
(dendritic spines (branches) can grow = linked to brain plasticity) |
|
|
Axon |
Extension that transmits neural info to other neurons (or muscles and glands) |
|
|
Myelin |
White, fatty substance that surrounds and insulates the axon (myelin sheath) |
|
|
Why is the myelin sheath important for neural transmission? |
-insulates and protects axon (prevents interference) -allows for neural messages to be sent faster |
|
|
Axon terminals |
Contains terminal buttons which have sacs (vesicle sacs) that store and secrete neurotransmitters that are produced by the neuron to carry messages to other cells |
|
|
What are the three components that make up the synapse? |
1. Dendrites of the post-synaptic neuron 2. Synaptic gap 3. Axon terminals of the pre-synaptic neuron |
