❌: Receives info from the other neurons & transports it to the cell body.

❌: Controls the metabolism and maintenance of the neuron

❌: The sheath covering the axon, protecting it from other chemical or physical interference

❌: Transmits the Information to the next neuron; the terminal ends have sacs that secrete neurotransmitters.

Neurotransmitters are ❌ that transmit information from one neuron to the next. The ❌ signal travels down the axon, is converted into a ❌ signal (neurotransmitter), travels across the ❌ and into the ❌ of the next neuron. This process is called ❌

❌ neuron: Causes the neurons to fire
- When an axon fires the terminal ❌ (ends) of the excitatory synapse release a neurotransmitter that excites the postsynaptic neuron, causing it to reach its ❌.
- ❌ is an excitatory neurotransmitter that increases the chance of an action potential being generated. Involved in learning and ❌

❌ neurotransmitter: inhibits neuron from firing
- In contrast when the inhibitory synapses are activated, the firing rate of the postsynaptic neuron is ❌ and sometimes does not fire at all.
- ❌ has an inhibitory effect on the brain. It decreases the chance of action potential being generated. Regulates ❌.
