Apr 26, 2021 · The cell body is a key structural component of neurons which are the basic functional units of the nervous system. The key role of neurons is to receive information from cells (via their dendrites) and pass this information on to other cells (through the axon).

Epithelial tissue consists of tightly packed sheets of cells that cover surfaces—including the outside of the body—and line body cavities. For instance, the outer layer of your skin is an epithelial tissue, and so is the lining of your small intestine.
- Yes. Glial cells are the neuron's "helper". They provide neurons with support, insulation, and protection.
- One of the more well-known hormones that are made in the brain is the *Growth Hormone*, which is produced by the pituitary gland. It is a small gla...
- I would say it depends on the organism and how it functions! For example, we are quite complex (organ-wise) and are obviously quite successful anim...
- Arteries have an outer tube of connective tissue for structural support. And smooth muscle tissue makes next layer. Smooth muscle tissue layer allo...
- Cells of connective tissue work in synergy. They provide matrix (as some form of a skeleton) which is 'invaded' with mobile or fixed cells of conne...
- Every tissue has its role in an organ! Epithelial gives protection, skeletal gives support, muscle helps locomotion and neural conducting signals!...

2 days ago · cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
- A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of...
- Cell theory states that the cell is the fundamental structural and functional unit of living matter. In 1839 German physiologist Theodor Schwann an...
- The cell membrane surrounds every living cell and delimits the cell from the surrounding environment. It serves as a barrier to keep the contents o...
An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body.

Aug 14, 2020 · The plasma membrane (often called the cell membrane) is a thin flexible barrier that separates the inside of the cell from the environment outside the cell and regulates what can pass in and out of the cell. Internally, the cell is divided into the cytoplasm and the nucleus.
Dec 19, 2023 · A cell is the smallest living organism and the basic unit of life on earth. Together, trillions of cells make up the human body. Cells have three parts: the membrane, the nucleus, and the...
