The Cell Body

5. The cell body of the neuron, responsible for maintaining the life of the cell and containing the mitochondria is the soma.

There are many parts of a cell, they all have specific duties, and are all

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms

The axons are slender processes of uniform diameter arising from the hillock. There is usually only one unbranched axon per neuron.

In this report i will be writing brief description on the functions of the main cell components of the body cell.

The main components of the synapses are as follows: The Axon terminal, found at the end of the Axon, passes neurotransmitters to other neurons via synaptic transmission. Synaptic Vesicles contain neurotransmitters within the Axon. Neurotransmitters themselves are chemical messengers that travel through the neurons and activate receptors on the receiving cell. The neurotransmitters are diffused through the synaptic cleft—a region between the two neurons and gap the neurotransmitter needs to cross to make it to the receiving cell. Said receiving cell is what receives the neurotransmitters and starts the process over again. The receptors on the cell are structures that receive the neurotransmitters and

One extension is different from all the others, and is called the axon. Although in some neurons, it is hard to distinguish from the dendrites, in others it is easily distinguished by its length. The purpose of the axon is to transmit an electro-chemical signal to other neurons, sometimes over a

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:

As soon as the electrical signal reaches the end of the axon, mechanism of chemical alteration initiates. First, calcium ion spurt into the axon terminal, leading to the release of neurotransmitters “molecules released neurons which carries information to the adjacent cell”. Next, inside the axon terminal, neurotransmitter molecules are stored inside a membrane sac called vesicle. Finally, the neurotransmitter molecule is then discharged in synapse space to be delivered to post synaptic neuron.

Information conveyed by the synapses on the dendrites is processed and projected from the axon. The axon is extraordinary, it is specialized for signal conduction to the next neuron. Axons vary in length, the ones in your brain are relatively short in comparison to the axons that run from your spinal cord down to your foot (about a meter long).

The human body uses unspecialised sperm cells which come from egg cell from the female or sperm cell form the male (zygote) then they specialise into neuron and skeletal muscle or any other type of cell. The stem cells are the building blocks they go through a various process called stem cells differentiation which allows them to be specialise.

Kidneys are one of the most essential organs in a human body which are crucial for blood filtration, toxins, and waste removal and maintaining and regulating the body’s pH. The researchers created kidney structures from induced pluripotent stem cells (iPS) called organoids which have the function and structural organization of a human fetal kidney in the first trimester. This study used the results of a previous study where human embryonic stem cells were differentiated towards a renal lineage. As a result, the progenitors for both collecting ducts and nephrons were generated from iPS. In that study, the researchers found out that although both nephrons and collecting ducts originate from the intermediate mesoderm layer, they develop at a different specific time and area from the mesoderm layer. The intermediate mesoderm layer is a germ layer arising from the mesoderm, and it is important in the development of kidneys, reproductive system, and lower urinary tract of the embryo. Thus, the scientists exploited this temporospatial origin difference, and they identified the regulating mechanism behind what caused the induction of collecting duct versus other kidney progenitors like the nephrons for instance. As a result of this finding, kidney organoids were formed which were segmented into distal and proximal tubules, loops of Henle, glomeruli, and podocytes which establish a vascularization network. This study is important in near future because it can be used as a model for
