Study Notes
Neural Transmission
- Soma: The cell body of a neuron, containing the nucleus. It transmits electrical impulses.
- Axon: A long projection extending from the soma, transmitting impulses towards other neurons. It stimulates the release of neurotransmitters.
- Dendrites: Finger-like projections that receive messages from other neurons.
- Myelin Sheath: A fatty substance wrapping around some axons, insulating them and making nerve impulses travel more efficiently.
- Nodes of Ranvier: Gaps in the myelin sheath where the action potential jumps.
- Synapse: The junction between the axon of one neuron and the dendrite of another. This is where information is transmitted.
- Terminal Button: A knob at the end of an axon containing neurotransmitter sacs.
- Neurotransmitters: Chemicals released at the synapse to communicate with the next neuron.
Types of Neurons
- Sensory Neurons: Receive sensory information from sense organs and transmit it to the brain for processing.
- Motor Neurons: Receive commands from the brain and carry them to muscles, controlling body movements.
- Interneurons: Communicate only with other neurons. They connect neurons in different parts of the brain, relaying information from sensory to motor neurons. They also activate when observing others performing actions.
