What are short fibers that branch out from the cell body and pick up incoming messages?
|Dendrites||Short fibers that branch out from the cell body and pick up incoming messages|
|Family Studies||Studies of heritability in humans based on the assumption that if genes influence a certain trait, close relatives should be more similar on the trait than distant relatives.|
What is the function of the long fiber that extends from a neurons cell body?
The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. The larger the diameter of the axon, the faster it transmits information. Some axons are covered with a fatty substance called myelin that acts as an insulator.
Which part of the neuron carries messages to other cells?
What is an axon in psychology?
n. the long, thin, hollow, cylindrical extension of a neuron that normally carries a nerve impulse away from the cell body. An axon often branches extensively and may be surrounded by a protective myelin sheath.
What is the function of an axon psychology?
The axon, also called a nerve fiber, is a tail-like structure of the neuron which joins the cell body at a junction called the axon hillock. The function of the axon is to carry signals away from the cell body to the terminal buttons, in order to transmit electrical signals to other neurons.
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 does Axon mean?
: a usually long and single nerve-cell process that usually conducts impulses away from the cell body — see neuron illustration.
What does Axon stand for?
Autonomous eXtended On-Officer Network
What is the definition of axon terminal?
aka synaptic boutons, axon terminals are small swellings that are found at the terminal ends of axons. They are typically the sites where synapses with other neurons are found, and neurotransmitters are stored there to communicate with other neurons via these synapses.
Where is Neurilemma found?
Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann’s sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system.
What is the difference between Neurilemma and myelin sheath?
Neurilemma: Neurilemma is the plasma membrane of Schwann cells that surrounds the myelinated nerve fibers. Myelin Sheath: Myelin sheath is the insulating covering of the nerve fibers that increase the speed of conduction of nerve impulses.
