Bio Psych Flashcards
Nervous System
Communication systems of our body
Send signals of pain, pleasure, emotions, reflexes, etc.
Neuron
Cell in the nervous system that sends and receives messages
Axon
Long structure off of the cell body that transmits information to the next cell
Dendrite
Branches off of the cell body, receiving information from other cells
Neurotransmitters
Chemicals that allow neurons to communicate with one another
Different types of neurons
Sensory
Motor
Interneurons
Sensory
Gather information from the senses
Motor
Allow the brain to tell the body how to move
Interneurons
Excite or inhibit communication between sensory and motor neurons
Resting Potential
The stable state of a neuron that is not transmitting messages
Action Potential
Wave of electrical activity that travels the length of the axon
Refractory Period
Time when a neuron cannot fire
Cycle
Rest –> Action –> Recover
Glial Cells
Cells that protect brain cells and help synchronize the cell’s communication
Myelin Sheath
Insulation between axons helps and make communication between cells efficient
