Cell Structure and Function

The word “cell” came from the Latin word “cellus,” meaning “little room.” Over one trillion cells make up the human body. Because cells are specialized to execute distinct jobs, they vary in size and shape. Some creatures, such as bacteria, protozoans, and algae, have only one cell in their bodies. Higher animals, plants, and fungi, […]

Introduction  As we know, every living organism comprises the microscopic unit, i.e. cells. These cells vary in their shapes, sizes, function and even differ in different organelles as per the organism. The animal cell consists of the well-developed nucleus as in other eukaryotic cells. The cells range in between 1 to 100 micrometres. We can

Nervous tissue makes up the nervous system in the human body. It allows the system to link the brain with the rest of the body and transmit and receive messages between them. The central nervous system controls movement, thought, sensation, and emotion, while the peripheral nervous system conveys information to and from the central nervous

Epithelial tissue also known as the epithelium is one of the basic tissues which is the part of the whole human body. The cells of this tissue are arranged in a manner where very little intercellular space is present between the cells. The epithelial tissue or the epithelium is present on the outer layer of

Connective tissue is animal tissue and is formed from cells. Its function is connecting different tissues, supporting tissues, and organs. Connective tissue can be divided into three types based on the arrangement of the cells. The types are Loose, Dense, and Specialised connective tissue. Loose connective tissue functions to keep the organs in their specific

In Latin the word tissue means that ‘weave’, a bunch of cells required to make a tissue that performs a particular cellular organism. The study of tissues is thought as microscopic anatomy. Tissues play a vital role within the body’s overall performance and lots of forms of tissues exist in each plants and animals. On the idea of the functions they perform we are able to consider differing types of

Collagen is a structural protein found in the extracellular matrix of connective tissues throughout the body. It is the most abundant protein in mammals, accounting for 25 to 35 percent of total protein content. It is the main component of connective tissue. Collagen is made up of amino acids bonded together to form a collagen

The bacterial flagellum is generally a helical filamentous organelle which is  responsible for motility. In bacterial species possessing flagella at the cell exterior, the long helical flagellar filament serves as a molecular screw to create thrust. Meanwhile, the flagella of spirochetes remains within the periplasmic space and it not only serves as a cytoskeleton in

Pituitary adenomas are among the most common types of intracranial tumours like meningiomas, gliomas, and schwannomas. A large number of pituitary adenomas are relatively slow-growing and benign. This is the most common disease that affects the pituitary gland. People of age thirty to forty are more likely to be affected by this disease. These types
