Lobes
The Brain is divided into how many lobes? Name them.
4 lobes! Frontal, Temporal, Parietal, and Occipital Lobe
Which part of the brain controls heartbeat and breathing?
The Medula!
How is the Peripheral Nervous System (PNS) different from the Central Nervous System (CNS)?
The PNS includes the nerves all over our body (cranial and spinal nerves), but the CNS includes only the brain and the Spine. Though the PNS is connected to the CNS.
What is melatonin?
It is associated with your quality of sleep. It is a natural hormone produced in your brain that helps to regulate your body's sleep-wake cycle.
Which disorder is caused by abnormal electrical activity in the brain?
Seizures
This Lobe is mainly in charge of the sight, translating what we see into something we can understand.
The Occipital Lobe!
What two main structures are included in the Central Nervous System?
The Brain and Spine.
Somatic Nervous System - voluntary, relays information from skin, sense organ and skeletal muscles to CNS
Autonomic Nervous System - involuntary, relays information to internal organs
Which drug(s) acts as a stimulant to the Nervous System?
Caffeine and Nicotine
What does multiple sclerosis damages?
The body's immune system eats away at the protective myelin sheaths that covers axons of the neurons and interferes with communication between nerves.
What is conservation, a concept discussed by Piaget? Summarize in your own words, based on the notes.
It is the ability to understand that different objects although they might have the same height, will hold different amounts of liquid because of the different shape of the object.
What is the cerebellum responsible for?
The cerebellum is responsible for coordination of movement and aspects of motor learning.
All of which are which nervous System at work?
slowing heart rate after stress, increasing saliva and stomach acid for digestion, constricting pupils, and contracting the bladder to urinate.
The Parasympathetic Nervous System
Your blood can easily take in alcohol, so your body quickly absorb it and it slows down functions in the Nervous system.
What happens in parkinson's disease?
shaking (tremors) and difficulty with walking, movement, and coordination, and have low brain dopamine concentrations.
One cortical region will often compensate for another region which is not functioning optimally. Essentially, another part of the brain will help it out!
What is the difference between Broca's and Wernicke's area? i.e. what are their functions or what does this areas do?
Broca's are is important for the production of speech while Wernicke's are is responsible for comprehension of language and the production of meaningful speech.
Give at least two example of an action that would controlled by the Peripheral nervous System
heart rate regulation, digestion, breathing, sweating, pupil dilation, and transmitting sensory information like pain or touch from the skin
What affect does Marijuana have on the Nervous system?
The suppression of memory and learning centers in the brain.
What causes chickenpox?
The varicella-zoster virus, the virus remains inactive in certain nerves in the body.
What parts of the brain did we test, using the blindfolded spatial task lab? What is the function of that or those lobes?
What part of the brain is damaged is a person a person cannot speak but can understand language?
Most likely has damage to Broca's area, a condition known as Broca's aphasia.
Describe the process of why your hand would instinctively move away after accidentaly touching a hot stove.
When touching something hot, sensory nerves in the hand (PNS) send signals to the spinal cord (CNS), which immediately sends a signal back via motor nerves (PNS) to withdraw the hand.
Both Caffeine and Nicotine act as a stimulant for the Nervous system, but what is the difference between the two drugs' effects on the Nervous system?
Which two neurological conditions both affect movement and coordination, but differ in cause—one results from low dopamine levels in the brain, while the other stems from damage to the developing brain.
Parkinson’s Disease and Cerebral Palsy
