In developing neurons, microtubules are also nucleated at the centrosome (located in the soma of the neuron), but the microtubules are then released from the centrosome for subsequent transport into axons and dendrites (Ahmad and Baas, 1995; Ahmad et al., 1994; Ahmad et al., 1999; Yu et al., 1993).

What organelles are found in the soma?
The cell body (soma) is the location of the nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular components; it connects to different parts of the neuron such as dendrites, and the axon.
What does the presence of mitochondria indicate?
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Where is the soma in a neuron?
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.
Which of the following are found in the soma?
The Soma (Latin, som / a: body) or cell body of a neuron contains the nucleus and other structures common to living cells. These structures support the chemical processing of the neuron; the most important of which is the production of neurotransmitters.
What part of the cortex contains the somas of neurons?
Gray matter consists primarily of neuronal cell bodies, or soma. This a spherical structure that houses the neuron’s nucleus.
What produces proteins in the soma?
The cell nucleus is a key feature of the soma. The nucleus is the source of most of the RNA that is produced in neurons. In general, most proteins are produced from mRNAs that do not travel far from the cell nucleus. The axon hillock is a specialized domain of the neuronal cell body from which the axon originates.
Where are mitochondria located?
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).
Was mitochondria a virus?
Mitochondria originated from symbiotic bacteria but co-evolved with their host as most of the mitochondrial proteins are encoded by the nucleus. However, the mitochondrial genome encodes proteins critical for respiration.
Where on the neurons are the dendrites located?
Dendrites. Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area of the cell body.
What is the soma in the brain?
Cell body. Also known as a soma, the cell body is the neuron’s core. The cell body carries genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.
What is the soma of the cell?
the cell body of a neuron, which contains the nucleus and various other organelles.
What is the soma of an axon?
The soma is the cell body of a nerve cell. Myelin sheath provides an insulating layer to the dendrites. Axons carry the signal from the soma to the target. Dendrites carry the signal to the soma.
What is the myelin sheath?
Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down. This can cause diseases such as multiple sclerosis.
What contains Soma?
Soma Compound ( carisoprodol and aspirin tablets, USP) is a fixed-dose combination product containing the following two products: 200 mg of carisoprodol, a centrally-acting muscle relaxant • 325 mg of aspirin, an analgesic with antipyretic and anti-inflammatory properties.
What is Neuroglial cell?
Neuroglial cells or glial cells provide supporting functions to the nervous system. Glial cells are found in the central nervous system (CNS) and peripheral nervous system (PNS). The important CNS glial cells are astrocytes, microglia, oligodendrocytes, radial glial cells, and ependymal cells.
