What is a cell body?
The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8.2). The cell body is the metabolic center of the neuron.
Where is the cell body?
The cell body (AKA the soma) is one of the three main parts of a nerve cell (or neuron). It's the rounded, bulbous part of the cell that houses the nucleus, along with other key organelles like the endoplasmic reticulum, ribosomes, mitochondria, and Golgi apparatus.
What is cell body in psychology?
the part of a neuron (nerve cell) that contains the nucleus and most organelles. Also called perikaryon; soma. See also axon.
What is a cell body quizlet?
The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus and holds all of the general parts of the cell. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
What are the parts of cell body?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.
Which of the following is a part of cell body?
Cell body: the cell body of a neuron is also known as soma. The soma contains cellular organelles and the nucleus. It contains the genetic material which forms various proteins in the cell. The soma is covered with a protective membrane.
What does the cell body do in a neuron simple explanation?
The cell body is the spherical part of the neuron that contains the nucleus and connects to the dendrites, which bring information into the neuron, and the axon, which sends information to other neurons. The job of the cell body is to control all of the functions of the cell.
What is the function of the cell body quizlet?
The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus and holds all of the general parts of the cell. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
Is cell body a neuron?
A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively.

What are the parts of a cell and their functions?
What's found inside a cell
| Organelle | Function |
|---|---|
| Nucleus | DNA Storage |
| Mitochondrion | Energy production |
| Smooth Endoplasmic Reticulum (SER) | Lipid production; Detoxification |
| Rough Endoplasmic Reticulum (RER) | Protein production; in particular for export out of the cell |
Is the cell body known as a axon?
An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body….

What does the cell body of a neuron contain?
The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons.
What is the most important part of a cell?
The nucleus is said to be one of the most important parts of the cell of eukaryotes.
What is the function of cell wall?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What are the parts of a cell and its functions?
The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth. Every cell has one nucleus and membrane-bound organelles in the cytoplasm. Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.
What controls the cell function?
The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell.
What is the function of nucleus?
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
What are the four functions of a cell?
Cells perform the following functions: Produce energy. Support growth. Provide structural support.
What are the four basic functions of a cell?
The essential functions of the cell include:
- The cell provides support and structure to the body.
- It facilitates growth by mitosis.
- It helps in reproduction.
- Provides energy and allows the transport of substances.
What are the three most important functions that a cell performs?
3 Major Functions of a Cell
- Energy Generation. Living cells exist in a perpetually active biological state. …
- Molecular Transport. Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell. …
- Reproduction.

How do cells perform different functions?
In a multicellular organism, cells become specialized to perform different functions through the process of differentiation. In order to do this, each cell keeps in constant communication with its neighbours.
What is Golgi body function?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
What is the function of a cell wall?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What are the 3 main functions of a cell?
What Are The Three Functions Of All Cells?
- Produce energy.
- Support growth and repair.
- Provide structural support.
Which of these is a function of all cells?
Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.

What is the function of lysosomes?
Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.
