Bio 2.3
This document summarizes four types of carbon compounds found in living things: carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates are the main energy source, while lipids can store energy. Nucleic acids store and transmit genetic information. Proteins control reactions, regulate cell processes, form tissues, transport substances, and fight disease. Monomers like sugars and amino acids combine to form these larger polymers.
Biology 12 - Chemistry of Water and Carbon - Section 2-3 and 2-4
This document provides an overview of sections from a cell biology textbook. It discusses:
1) The properties of water, including its role as a solvent, high heat capacity, hydrogen bonding, and importance for life. Water's properties allow it to act as an efficient transport system and cool the body.
2) Acids, bases, and pH. Acids release hydrogen ions in water while bases release hydroxide ions. The pH scale measures hydrogen ion concentration. Buffers help maintain pH within a narrow range.
3) Organic molecules that make up life, including monomers that join to form polymers through dehydration reactions. Degradation occurs through hydrolysis reactions. Carbon allows formation of many organic compounds
Biology Lesson 10.2
The document lists various anatomical terms related to the heart and its chambers, valves, arteries, and overall functioning. The heart is a muscular organ that pumps blood through the body using four chambers and valves to ensure blood flows in one direction, and it can experience problems if the muscle tissue is damaged or not contracting and relaxing properly.
A and P Notes229 235
This document lists various anatomical structures and terms related to the brain and meninges. It includes structures like the basal nuclei, amygdala, hippocampus, ventricles, choroid plexuses, commissures, and meninges (dura mater, arachnoid mater, pia mater). Additionally, it notes the basal nuclei are inhibitory in nature and their dysfunction can cause disorders such as Parkinson's disease, Huntington's disease, obsessive-compulsive disorders and Tourette's.

The brain weighs about 3 pounds and is composed of bundles of neurons that process information. It requires a constant supply of oxygen and glucose to function properly. There are four major divisions of the brain: the brain stem, diencephalon, cerebellum, and cerebrum. The cerebrum is the largest part and is responsible for higher level functions such as thought, language, and reasoning. It is divided into four lobes - frontal, parietal, occipital, and temporal - each of which controls different functions.
A and P Polarization
The action potential is an electrochemical signal carried by neurons. It is initiated by a stimulus that opens sodium channels, allowing sodium ions to enter the neuron and depolarize it. Repolarization occurs as potassium channels open and sodium-potassium pumps restore ion concentrations. The action potential then propagates down the axon through continued depolarization of adjacent areas. At synapses, neurotransmitters trigger action potentials in the next neuron. Different arrangements of neurons allow signals to converge, diverge, or oscillate in circuits.

The document provides an overview of the nervous system, including its main functions and divisions. It discusses the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which branches out from the CNS. Within these systems are neurons, the main cell type, and neuroglia which support neuron function. The document outlines the structure of neurons and how nerve impulses are conducted. It also describes the divisions of the nervous system including somatic, autonomic, afferent and efferent systems.

This document discusses ways to keep the digestive tract healthy such as eating fiber, drinking water, relaxing, and exercising. It then lists and describes common gastrointestinal disorders including food poisoning caused by bacteria like Staphylococcus aureus and Salmonella from meat and dairy, dyspepsia or indigestion, peptic ulcers which are open sores in the stomach caused by bacterial infection that can bleed if untreated, constipation from removing too much water, diarrhea from not enough water removal, dysentery caused by bacteria, protozoa, or viruses where sanitation is poor, and colon cancer which is a common cancer that is 95% curable if detected early and may be related to diet.
Biology Lesson9.2
This document lists various scientific terms related to nutrition and the human body, including carbon, animals, water, coenzymes, vitamin B12, lipids, stored, neutralize, free, complexes, xerophthalmia, clotting, immune, iodine, bones, iron, goiter, cells, food, drink, dehydration and more. It covers over 60 entries of single words or short phrases touching on different biological components and processes.
Biology Lesson 9.3
This document discusses nutrition, caloric intake, and food groups according to the food pyramid. It defines key terms like nutritionists, balanced diet, and food guide pyramid. It then explains the six main food groups and recommended daily servings. The document also covers calorie measurement, basal metabolism, recommended daily calorie intake, weight loss strategies, and artificial food additives and preservatives.
Biology Lesson9.1
This document discusses human nutrition and digestion. It explains that we need to intake and digest food for structural materials to rebuild cells, and for energy through the process of oxidation. The main molecules needed are carbohydrates, proteins, and lipids. Carbohydrates provide our main source of energy through glucose and ATP. Proteins are building blocks made of amino acids. Lipids are a stored energy source and used for building cell membranes, with unsaturated fats being healthier than saturated fats.
Biology Lesson8.3
The brain contains three main parts: the cerebrum, cerebellum, and brain stem. The cerebrum is divided into left and right hemispheres and four lobes. The cerebellum coordinates muscle control to allow the cerebrum to think. The brain stem regulates vital functions and links the cerebrum to the spinal cord, consisting of the medulla, pons, and midbrain.
Biology Lesson8.3
The brain has three major parts:
1. The cerebrum, which is divided into left and right hemispheres that control opposite sides of the body and have different functions.
2. The cerebellum, which coordinates muscle control and movement.
3. The brain stem, located at the base of the brain, which regulates vital functions like breathing and contains structures like the medulla, pons, and midbrain.
Biology Lesson8.1
The nervous system is divided into the central nervous system (CNS; brain and spinal cord) and peripheral nervous system (PNS; nerves connecting CNS to body). The CNS is protected by meninges and cerebrospinal fluid. Neurons are the basic functional units and have a cell body, dendrites, and axon. The PNS is divided into somatic and autonomic systems. The autonomic system regulates involuntary functions and has sympathetic and parasympathetic divisions.
Biology Lesson 7.5
The document discusses the three main types of muscle in the body:
1. Cardiac muscle found only in the heart that contracts involuntarily over long periods.
2. Smooth muscle found in organs that contracts involuntarily through slow, powerful contractions.
3. Skeletal muscle that is striated, contracts voluntarily through quick, powerful contractions and is attached to bones by tendons.
A and P Mod5
The document discusses the structure and function of the three main types of muscle tissue - skeletal, smooth and cardiac - describing their characteristics, the sliding filament model of contraction, motor unit recruitment, and the energy systems that power muscle contraction. Skeletal muscle is made of bundles of striated muscle fibers attached to bones via tendons that contract through calcium-induced actin-myosin crossbridge cycling powered by ATP hydrolysis.
Biology Lesson 7.7
This document discusses the different types of muscle fibers and how they affect muscle function. It describes:
1) Red muscle fibers that contain many mitochondria and myoglobin, allowing for slow contraction but great endurance.
2) White muscle fibers that contain fewer mitochondria and myoglobin, allowing for fast contraction but quick fatigue.
3) Most muscles contain a combination of red and white fibers, using red fibers primarily but activating white fibers when rapid, forceful movement is needed.
Biology Lesson7.6
This document describes the structure and function of muscle cells and fibers. It discusses three layers of wrappings (endomysium, perimysium, and epimysium) that surround muscle fibers. It also details the structures within muscle cells, including nuclei, mitochondria, sarcoplasmic reticulum, myofibrils, and sarcomeres. Finally, it explains how muscles contract through motor neuron stimulation of muscle fibers and the role of the neuromuscular junction in transmitting nerve impulses to cause contraction.
