Thinking Assignment Essay
Axon: long tube like structure that conveys impulses away from the neurons cell body toward other neurons/muscles or glands 3. Cell Body: part of the neuron containing the cell nucleus as well as other structures that help the neuron carry out its functions; also known as the soma 4. Myelin Sheath:layer of fatty insulation wrapped around the axon of some neurons, which increases the rate at which nerve impulses travel along the axon. 5.
Terminal Branches of the Axon: junctions with other cells that releases chemicals called neurotransmitters.
6. Action Potential (here also describe threshold): level of stimulation received when a neuron is in its resting state and it determines if an electrical signal or neural impulse will be created or not. If the threshold is met, the neural impulse will form and be sent down the axon. If not, the impulse won’t occur. 7. Synapse: small gap between neurons. 8.
Neurotransmitters: are chemicals that are released by the sending neuron that activates the receptors on the receiving neuron.
9. Eruptive: the remaining neurotransmitter molecules in the synaptic gap goes back up by the sending neuron. 10. Describe how an SIR antidepressant medication works. SIR stands for selection serotonin eruptive inhibitor. Girl’s works by slowing the eruptive of the serotonin in the brain. The higher level in the synaptic gap helps to overcome depression and enhance moods.
