Question

unit 3 worksheet biopsychology

1. this nervous system has motor neurons that stimulate smooth (involuntary) muscle, heart muscle. and it aids biological functions (breathing, digestion, heartbeat) this is the ____ nervous system.
2. every cell in your body has __ pairs of chromosomes; each chromosome consists of __.
3. control of one side of your body by the other side of your brain is known as ____.
4. explain what phantom limb syndrome is. (use the internet if you want to)
5. this calms you down....it restores and repairs spent energy following sympathetic nervous system stimulation (calm state) lowers arousal levels - pupils return to normal size, breathing and heart rate return to normal, etc.... the ____ nervous system.
6. these cells process incoming signals and respond by sending out signals of their own, they are the basic building blocks of the brains anatomy. ____
7. neurons dont touch each other......what is that gap in between neurons called?
8. these are short, thin, tubular fibers that branch out from the outer membrane. they receive messages from adjacent neurons and sends them to the cell body,these are called ____
9. what is the axon terminal...aka the axon button?
10. explain the

ature vs nurture\ debate (controversy)

1. which hormone is released in response to stress?
2. when the nt acetylcholine (ach) levels get low or start slowing down, you may be at risk for this disease ____
3. this is a fatty tissue that protects information stored in the axon. it helps with the speedy transition of information. (you may be risk of multiple sclerosis if this is destroyed)......what is the name of this fatty tissue?

Explanation:

1. The autonomic nervous system controls involuntary functions like breathing and heartbeat.
2. Human body cells have 23 pairs of chromosomes, made of DNA.
3. Contralateral control refers to one - side brain controlling the opposite side of the body.
4. Phantom limb syndrome is the sensation of pain or other feelings in a limb that has been amputated, likely due to the brain's neural pathways associated with the limb still sending signals.
5. The parasympathetic nervous system restores the body to a calm state after sympathetic stimulation.
6. Neurons are the basic building blocks of the brain's anatomy, processing and sending signals.
7. The gap between neurons is called the synapse.
8. Dendrites are short, thin fibers that receive messages from adjacent neurons and send them to the cell body.
9. The axon terminal (axon button) is the end - part of the axon that releases neurotransmitters into the synapse to communicate with other neurons.
10. The "Nature vs Nurture" debate is about whether human behavior, traits, and development are mainly determined by genetic factors (nature) or environmental factors (nurture).
11. Cortisol is a hormone released in response to stress.
12. Low acetylcholine levels are associated with an increased risk of Alzheimer's disease.
13. Myelin is the fatty tissue that protects axonal information and aids in fast signal transmission; its destruction can lead to multiple sclerosis.

Answer:

1. Autonomic
2. 23; DNA
3. Contralateral control
4. Sensation of pain or other feelings in an amputated limb due to remaining neural pathways in the brain sending signals.
5. Parasympathetic
6. Neurons
7. Synapse
8. Dendrites
9. The end - part of the axon that releases neurotransmitters into the synapse to communicate with other neurons.
10. Debate on whether human behavior, traits, and development are mainly due to genetic (nature) or environmental (nurture) factors.
11. Cortisol
12. Alzheimer's disease
13. Myelin
