Biological Basis of Behavior Assignment
Label the following on the neuron by clicking on each labeled arrow and dragging it to point to the correct location: Dendrite, Axon, Cell Body, Myelin Sheath, Terminal Branches of the Axon
Briefly describe the role each of the following play in neural communication: 1.
Dendrite: Receives incoming messages from other cells.
Axon: Sends information from the cell body to other neurons.
Cell Body: Maintains the health of the neuron.
Myelin Sheath: Insulates axons, and speeds the transmission of neural impulses.
Terminal Branches of the Axon: Forms junctions with other cells.
Action Potential (here also describe threshold): The level of stimulation received when a neuron is in its resting state determines if an electrical signal or neural impulse (action potential) will be generated or not. If the threshold is met, the neural impulse will generate and be sent down the axon. If not met, the impulse will not occur.
Synapse: The small gap between neurons.
Neurotransmitters: A chemical released by the sending neuron that activates the receptors on the receiving neuron.
Reuptake: Remaining neurotransmitter molecules in the synaptic gap gets taken back up by the sending neuron.
Describe how an SSRI antidepressant medication works. SSRI stands for selection serotonin reuptake inhibitor. The antidepressant Selective serotonin reuptake inhibitors (SSRI) works by slowing the reuptake of the neurotransmitter serotonin in the brain. The increased level, of the naturally occurring chemical serotonin, in the synaptic gap is known to enhance moods and overcome depression. The Nervous System
