What is an example of an axon?
An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma. The longest axons in the human body, for example, are those of the sciatic nerve, which run from the base of the spine to the big toe of each foot.
What is the function of axons quizlet?
Axons: Conduct nerve impulses away from the cell body towards: the dendrites or cell body of another neuron or an effector (muscle or gland).
What are the functions of axons?
Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.
What is axon Class 9?
1)It consist of cell body which contain central nucleus and cytoplasm from which long thin hair like part arises called dendrons. 2)The axon is a single,long,cylindrical structure that conduct electrical impulses away from neuron’s cell body.
What are axons quizlet?
axon. A threadlike extension of a neuron that carries nerve impulses away from the cell body.
What is the function of synaptic vesicles?
Synaptic vesicles play the central role in synaptic transmission. They are regarded as key organelles involved in synaptic functions such as uptake, storage and stimulus-dependent release of neurotransmitter.
What function do astrocytes play in the CNS?
Astrocytes are the most numerous cell type within the central nervous system (CNS) and perform a variety of tasks, from axon guidance and synaptic support, to the control of the blood brain barrier and blood flow.
What is an axon Class 10?
3)Axon:It is a single,very long cylindrical fibre arising from cell body. They conduct nerve impulses away from cell body. They have an insulating and protective sheath of myelin around it.
What is the primary function of dendrites?
Dendrites are specialized extensions of the cell body. They function to obtain information from other cells and carry that information to the cell body. Many neurons also have an axon, which carries information from the soma to other cells, but many small cells do not.
