What is the type of cell with a long arm - the axon?
The type of cell with a long arm called the axon is a neuron. Neurons are specialized cells in the nervous system that transmit electrical signals throughout the body. The axon is the elongated part of the neuron that carries impulses away from the cell body to communicate with other neurons, muscles, or glands. This unique structure allows for efficient and rapid signal transmission over long distances.
Is fiber same as axon?
No, fiber refers to any thread-like structure in the body, while axon specifically refers to the long extension of a nerve cell that conducts electrical impulses. Axons are a type of fiber found in the nervous system.
What does the structure of a neuron look like?
There are three types of Neurone and a different structure for each. Each of these types has all the same part just in a different arangement. They have a part callled the Axon which is where they send their Action Potentials (impulses) down, parts called Dendrites which is the heavily branched part where they receive stimulationfrom and a part inbwetween called the Cell Body which is where the Nucleus is. We will look at them in the order they would come in a complex reflex arc. Firstly the Sensory Neurone: This type of cell has dendrites that are out on a stalk from the cell body. These dendrited are specialised to activate neurone when a specific stimulation type is present. The axon from this cell type is usually not so long as in motot neurones but substantially longer than in interneurones. The cell body sits roughyl in the middle ot the two branches (the axon and the dendrite branches). Secondly the Interneurone: This types of cell are what is mostly found in the brain. They have incredibly branched dedrites making them look very like a tree. Their axons may or may not be branched and their length OS also very variable. Finally the Motor Neurone: Here the cell body and the dendrites are very close together, infact the dendrites brach directly of from the cell body. The axon in a cell of this type is usually very long and not very branched at all. This part will be connected to another neurone to pass the singal (in the form of an action potential) on to whatever organ is to be affecteed.
What is active axon loss?
Active axon loss refers to the process in which the axons of neurons degenerate due to specific pathological mechanisms, such as inflammation or direct injury. This type of degeneration involves the breakdown of axonal structure and can contribute to neurological disorders and impairments in nerve function. Active axon loss is different from passive axon degeneration, which occurs as a result of more general cell death processes.
Which type of cell is composed of one dendrite and one axon and is found in the eye and nose a. pseudo-unipolar neuron b. Schwann cell c. bipolar neuron d. multipolar neuron?
bipolar neuron

What is action portential?
The most common type of action potential is the change in voltage down the axon of a neuron. In other words, it is an electrical signal that is sent down the axon of a nerve cell.
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the central nervous system?
Oligodendrocyte

What is the part of a neuron which acts as a tiny antennae and conducts signals toward the axon of that cell?
Dendrites are the part of a neuron that act as tiny antennae and receive signals from other neurons. These signals are then conducted toward the cell body and, if the signal is strong enough, passed along to the axon of the neuron.

What is a nerve cells adaptation to its function?
They have a long extension called an axon that is enclosed by a coating of myelin (generated by a different cell type) capable of acting much like a coaxial cable in electronics, rapidly propagating an excitation signal voltage pulse to the synapse where it is transferred chemically to another nerve cell.
Which type of cell is composed of one dendrite and one axon and is found in the eye and nose a. pseudo-unipolar neuron b. Schwann cell c. bipolar neuron d. multipolar neuron?
bipolar neuron
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system?
Schwann cells enhance the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system by forming a myelin sheath around the axon. This myelin sheath insulates the axon, allowing for faster conduction of the action potential through a process known as saltatory conduction.
What is the name for a cell that does have nucleus?
This type of cell is called a Eukaryote.
What is the name of an cell that does not have a nucleus?
The type of cell that does not have a nucleus is called a Prokaryote cell.
