Central Nervous System In the movie the Wizard of Oz‚ the Scarecrow desperately wanted a brain. He opened his lips‚ blinked his eyes‚ shook his head and said‚ “I haven’t got a brain‚ I’ve only got straw.” The reason for the emphasizing of his actions is because without a brain‚ those functions are not possible. The brain is the center of the entire body. It controls what we do and how we do it. The brain is the center of the central nervous system along with the spleen. It consists of 100

Question 1 In a resting state‚ the axon is polarized‚ with mostly positively charged ions outside and negatively charged ions inside. Question 2 In the brain‚ learning occurs as experience strengthens certain connections in cell work groups called neural networks. Question 3 When the effect of one factor (such as environment) depends on another (such as heredity)‚ we say there is a(n) ________ between the two factors. interaction Question 4 Chromosomes are composed of a coiled

(Points: 4) | | As a general rule‚ communication within a neuron progresses from:1. the dendrites to the cell body to the axon.2. the axon to the dendrites to the cell body.3. the dendrites to the axon to the axon terminals and then to the cell body.4. the cell body to the axon to the nucleus. | | Save Answer | | 5.

Cell bodies are located in intermediolateral gray column of thoracic and lumbar vertebrae. Pregnaglionic neurons exit via ventral root → into white ramus communicans → synapse with postganglionic axon in peripheral ganglion at same level or another level. Neurotransmitter is acetylcholine. Postganglionic axons (unmyelinated)- relatively long -Cell bodies in peripheral ganglia extend to visceral organs ■ Distribution is widespread ■ Neurotransmitter is norepinephrine Sympathetic division Sympathetic

out of 1 points Place these items in the correct order of what happens when a neuron is stimulated and communicates with another neuron Selected Answer 1. Positive ions flow into axon‚ creating an action potential 2. Impulse reaches threshold intensity 3. Impulse moves all the way down the axon to the terminal buttons 4.

1. Which one‚ genetics (nature) or the environment (nurture)‚ do you think plays a larger role in the development of who you are? Please provide me with what percentage you think each contributes‚ for example‚ 50% genetics/50% environment. I personally feel like most of the habits you develop are from the environment (nurture). I would say it’s about 70% nurture and 30% nature. I believe that most of the habits people pick up are because they have seen it done by someone else. Now I do know of

the PNS is the Somatic Nervous System. The body communicates internally through Neurons and Neural Pathways. Neurons consist of dendrites that receive information from the Neuron‚ Axons that allow information to exit from the Neuron and the synapse which is the gap between the dendrite and axon. Released from the axon is a neurotransmitter which is a chemical that helps jump the synapse and the myelin sheath that speeds up the synapse and is made up of fat. There are several Neurotransmitters such
