Localization of the cerebellum in the human brain Introduction This part of the brain is located anteriorly to the medulla ablongata and is responsible for postural coordination during rest and activity. Cerebellum Functions It is also responsible for reflexes and voluntary movements, it also acts on the muscular system being responsible for muscle tone.

Kidneys: Several Important Functions in the Body What They Are Kidneys are excretory organs present in the body of vertebrate animals. Humans have two kidneys whose shape resembles beans. Functions of the kidneys The kidneys have important functions in the human organism such as: - Excrete waste through the urine (examples: urea and creatine); - Enable homeostasis (stable and constant condition) of the body; - Produce some types of hormones such as erythropoietin; - Regulate the volume of extracellular liquids; - Produce urine; - Excrete substances of external origin, such as medicines.
Cica: ornamental plant widely used in gardens. Main characteristics of the plant: - It is a semi-woody bush. - Its size is between 1.8 meters and 3 meters high. - Cica is a slow growing plant. Suitable environment for planting: - Full sun and also in half shade. Multiplication - Germination of the round fruits that are born in the female crests, which can be sown.
Blood Vessel: Conducting Blood Through the Body Introduction (What They Are) The circulatory system is made up of arteries, veins and lymphatic vessels, which aim to carry fluid through the body. It is divided into: - Cardiovascular system: formed by the veins, arteries and heart, which nourish and capture blood from tissues.
Plant Anatomy: study of plant structures What is (definition) Plant Anatomy is an area of botany intended for the study of plant structures. Often we only see the aerial parts of the plants (leaves, flowers, branches and trunk). However, many of the structures are below ground and cannot be seen.
Cellulose (microscope enlarged image) What it is (definition) Cellulose is a "long chain" polymer that is composed of a single carbohydrate (carbohydrate) monomer, classified as a polysaccharide. It is the primary structural component of plants and is not digestible by man. Main Characteristics of Cellulose Before we continue the topic of cellulose, it would be interesting to know a little about polymers, monomers and polysaccharides.
Plant Hormones: Multiple Functions in Plants What They Are Plant hormones, also known as phytohormones, are organic compounds produced by plants and play key roles in their growth and development. These hormones are present in small quantities and are produced in plant tissues.
Agapanto and Acanto-Greek: examples of angiosperms Introduction (what they are) Angiosperms are fruit-producing plants whose main function is to protect seeds. Most plants in the world are angiosperm (there are between 250,000 and 300,000 species). They can be monocotyledonous or dicotyledonous.

Mitochondria: Power Generation for Cells Introduction All cellular activity requires energy, it is through mitochondria that this energy necessary for the activities of cells will be generated. How Mitochondria Works To get energy, the cell must need glucose. Mitochondria have the function of breaking down glucose by introducing oxygen into carbon, what remains is carbon dioxide, which will exhale through exhalation.
Illustrative image of the organelles of a plant cell Introduction The plant cell has several organelles inside. Each of these organelles can perform one or more functions, all of which are of fundamental importance to cellular functioning. Plant cell organelles and their functions - Smooth and rough endoplasmic reticulum - enlarge the inner surface of the cell; favor the exchange of substances between the inner and outer part of the cell; favor circulation within the cell; store substances taken from hyaloplasma and lipid synthesis.
Plants Need Many Nutrients to Develop Introduction To develop, plants (except carnivores) need minerals (present in water), sunlight, and carbon dioxide. With these elements, plants perform the photosynthesis process to generate energy and to perform their physical development.
Osmosis Occurring in a Cell What is (definition) Passive transport is the transport that occurs between two solutions with different solute concentrations, which aims to equalize the concentrations, making them isotonic. This process occurs without the waste of energy. It is divided into two types: diffusion and osmosis.
Phases of meiosis Introduction Unlike in mitosis (where there is only one cell division), meiosis in two cells divides at the same time. How it happens (summary) The phases of this process (prophase, metaphase, anaphase, telophase, interphase) occur in the same way as in mitosis; only, in this case, double, because here we will have two cells going through the same process simultaneously.
Neutrophil: A type of granulocyte that acts on phagocytosis What they are (definition) Leukocytes (white blood cells) are the defense cells of our body, which are present in our blood. Granulocytes are a type of leukocyte whose main characteristic is the presence of granules in its cytoplasm.
Normal bone (left) with osteoporosis (right) What is it? Osteoporosis is a disease that decreases bone mass to such an extent that bones begin to fracture spontaneously in common everyday activities, such as sitting quickly, which can lead to a hip fracture.
Allergy Testing What is Allergy Allergy is an exaggerated immune system response. It is known that with each new contact with the triggering agent, it will occur faster and will manifest more aggressively. Allergic Process Before we understand how the allergic process occurs, it is interesting to understand that immunoglobulin is a protein of great importance to the human body, because it is the one that initiates the defense process against the invasion of microorganisms and infections.
Papilloma Virus (HPV) What it is - Definition STDs, also known as venereal diseases, are sexually transmitted diseases. They are infectious and transmitted through sexual intercourse. How to avoid The best way to avoid contamination with infectious agents that cause STDs is still the use of condoms, which besides preventing contamination, also prevents its spread.
Mycobacterium tuberculosis: Lung Tuberculosis-causing bacteria (Microscope image) Introduction Many types of bacteria that settle in the human body can cause disease. These bacteria can penetrate the human body in a variety of ways (body cuts, insect bites, contaminated food, air and water).
Protozoan Leishmania: Disease Cause Cause of Disease Leishmaniasis is a non-contagious disease caused by parasites (protozoan Leishmania) that invade and reproduce within the cells that are part of the immune system (macrophages) of the infected person. Manifestation and characteristics This disease can manifest itself in two ways: cutaneous or cutaneous leishmaniasis and visceral or kala-azar leishmaniasis.
