3 Dec 2017 A myelinated axon is one which is surrounded by a myelin sheath, comprised of Schwann cells. It is electrically insulating, except for gaps in 

Motor neuron: nerve that produces muscular activity. Motor end plate: muscular organ that becomes active in response to stimuli. Myelin sheath: envelope of phosphorated fats. The axon of neurons is covered by an insulating layer called the myelin sheath. The myelin sheath is formed by the oligodendrocyte in the central nervous system, and by the Schwann cell in the Neurons and Neuroglia Structures and function Synapse- The gap between each neuron that pass electrical or chemical signals to another cell.

system that is wrapped around a myelinated axon, providing one segment of its myelin sheath.

The axon of neurons is covered by an insulating layer called the myelin sheath. The myelin sheath is formed by the oligodendrocyte in the central nervous system, and by the Schwann cell in the

2017-09-20 · Axon and dendrite are two components of nerve cells. Nerve cells are the structural and functional units of the nervous system of animals. They transmit nerve impulses to the brain, spinal cord, and to the body to coordinate the functions of the body.

to define the following structures: ******* cell body myelin sheath dendrites axon Postganglionic neurons have short axons that terminate in the organ being 

Neurons are nerve cells that send "messages" all over the body, and Axon; Myelin Sheath; The dendrites are an extension of the neuron, and  Nerve cell anatomy shows cell body, axon, dendrite, myelin sheath, node of Ranvier, Schwann's cell and motor end plate or sensory organ on white background. Neurons may have hundreds of the branching dendrites, depending on the Each axon terminal is separated from the next neuron by a tiny gap called synaptic cleft. Because the myelin sheath is formed by many individual Schwann cells,  The parts of the neuron that we learned about are: the cell body, the axon, the dendrites, the myelin sheath and the axon terminal. We learned the job of each of  Suddenly your world is full of nodes, axons and sheaths; experts are talking to you about dendrites and lesions. What is Myelin? One of the words you're likely to  Axon. Nucleus.

Dendrite is a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body whereas an axon is a long slender projection of neuron that conducts electrical impulses away from the neuron’s cell body or soma. The myelin sheath is a protective covering that surrounds fibres called axons, the long thin projections that extend from the main body of a nerve cell or neuron. The main function of myelin is to protect and insulate these axons and enhance their transmission of electrical impulses. The myelin sheath is a layer of lipids which act as insulation to the axon.

Whilst neurones have many dendrites, most cells only have one axon. Each axon is There are gaps between the myelin sheaths formed by different cells.

Cell body: part of the nerve cell between the axon and the dendrite. Axon: extension of a neuron. Motor neuron: nerve that produces muscular activity.

The portion of the neuron that conducts impulses toward the cell body after receiving them from other neurons is the: A.dendrite. B.axon.
