What is the different between cytoplasm and axoplasm in nervous system?
The axoplasm is the cytoplasm of an axon.
What is an axoplasm?
An axoplasm is the cytoplasm of an axon - a nerve fibre which conducts nerve impulses away form the body of a cell, to a synapse.
Are all of the neurons organelles restricted to the cell body?
Not true. There are organelles like mitochondria, vesicles in the axoplasm in the axon.
Does a neuron have a axon?
Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.
Do axon contain a nucleus?
No, the axon is a fiber that emerges from a neuron, while the nucleus is in the center of the neuron.
How many axons does each neuron have?
Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.
What are the sacs that store chemicals in the axon terminal area?
The axon terminals contain chemicals, called "neurotransmitters," which are released in order for the cell to communicate with nearby cells.
Where does neuron and DNA exists?
All cells in the body (except those that do not contain a nucleus) contain DNA
What does a neuron cell contain?
A typical neuron consists of a cell body (soma), dendrites, and an axon.
What would happen to part of an axon if it is cut so that it is no longer connected to its nerve cell?
there wouldn't be an impulse . This can be seen in the injury of the breaking of the backbone/cutting of the spinal cord . The grey matter of the spinal cord is composed of motor neuron and accessory (?) neuron axons, and when these are cut, the impulses cannot be transmitted to the dendrites of the next neuron, or for that matter the effector. This results in paralysis from the site of injury down.
What are the components of a function?
The dendritic tree (to bind neurotransmitters (NTs)), the soma (also referred to as the cell body), the axon hillock (where action-potentials initiate), the axon (propagates the electrical signal), and the axon terminal (release of neurotransmitters). The membrane properties are also different to the average cell because they contain receptors and a high density of ion channels. Inside the cell, NTs are synthesized and 'shipped' down the axon to the axon terminal on long thin filaments propelled by tiny actin/dynein 'motors'. Once at the terminal, the NTs wait at the 'presynaptic active zone' for release (which is prompted by the electrical signal conveyed down the axon from the axon hillock).
