The second page delves into the detailed structure of the brain, examining its major regions and their specific functions. The brain's organization is presented from the primitive hindbrain to the sophisticated forebrain.

Definition: The cerebral cortex makes up 80% of brain mass and contains four specialized lobes: frontal, parietal, temporal, and occipital.

Highlight: The brain's wrinkled appearance convolutionsconvolutions serves to increase its surface area, allowing for more neural tissue in a confined space.

Example: The hypothalamus controls basic functions like hunger, thirst, and body temperature regulation.

Vocabulary: The thalamus acts as a sensory relay center, processing and directing incoming sensory information.

Page three explores hemispheric specialization and the intricate structure of neurons, the fundamental units of the nervous system.

Definition: The corpus callosum is a bundle of nerve fibers connecting the left and right hemispheres, enabling communication between them.

Highlight: The human brain contains approximately 100 billion neurons, each capable of forming thousands of connections.

Example: Broca's area and Wernicke's area, located in the left hemisphere, are crucial for speech production and language comprehension respectively.

Vocabulary: The myelin sheath is a fatty insulating layer that speeds up neural transmission.

The final page examines different types of neurons and the role of neurotransmitters in neural communication, completing our understanding of nervous system function.

Definition: Efferent neurons carry signals from the central nervous system to muscles, while afferent neurons transmit sensory information to the central nervous system.

Highlight: The closed loop system allows the body to react to stimuli before signals reach the brain, providing rapid protective responses.

Example: When touching a hot surface, the closed loop system triggers muscle withdrawal before the brain processes the pain sensation.

Vocabulary: Interneurons are the most numerous type of neurons in the brain, facilitating internal communication between neural networks.

The nervous system serves as the body's primary communication network, utilizing both electrical and chemical signals for rapid information transfer. The chapter introduces fundamental concepts about nervous system organization and neuron structure.

Definition: The nervous system is divided into the central nervous system brainandspinalcordbrain and spinal cord and the peripheral nervous system allothernervesall other nerves.

Highlight: The brain requires over 50% of the body's oxygen intake and can only survive 3-4 minutes without oxygen before damage occurs.

Example: The autonomic nervous system controls involuntary functions like heart rate and digestion through its sympathetic fightorflightfight-or-flight and parasympathetic restanddigestrest-and-digest branches.

Vocabulary: Neuroplasticity refers to the brain's ability to adapt and reorganize itself by forming new neural connections.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
