Axons terminate in a series of fine extensions known as?
Axon terminals, also known as synaptic boutons or end bulbs, are the fine extensions at the end of an axon that transmit signals to other neurons or effector cells. These terminals contain neurotransmitters that are released into the synaptic cleft to communicate with the target cell.
Why do nerve cells have fine extensions?
Nerve cells have fine extensions called dendrites and axons to receive and transmit electrical signals, allowing for communication between different parts of the nervous system. Dendrites receive signals from other neurons, while axons transmit signals to other neurons or target cells such as muscles or glands. These extensions enable nerve cells to integrate and relay information efficiently.
What wraps cytoplasmic extensions around thick neuron fibers in the CNS?
In the central nervous system (CNS), oligodendrocytes are the cells responsible for wrapping cytoplasmic extensions around thick neuron fibers. These extensions form myelin sheaths, which insulate the axons and enhance the speed of electrical signal transmission. Each oligodendrocyte can myelinate multiple axons, contributing to the efficiency of neural communication within the CNS.
How are axons similar to dentrites?
Axons and dendrites are both extensions of neurons responsible for transmitting electrical signals. However, axons transmit signals away from the cell body, while dendrites receive signals and transmit them toward the cell body. Both play crucial roles in the communication between neurons.
What are the characteristics of axonS?
Axons are long, thin, and cylindrical extensions of nerve cells that transmit electrical impulses away from the cell body to other neurons, muscles, or glands. They are covered by a protective myelin sheath, which helps to speed up the transmission of nerve signals. Axons can vary in length from a few millimeters to over a meter depending on the neuron's location in the body.
Neurons are composed of a network of fine threads called?
Neurons are composed of a network of fine threads called dendrites, which receive signals from other neurons, and axons, which transmit signals to other neurons. These structures form the basic communication network within the brain and nervous system.

What are the thin chain-like extensions of the neurons called?
Axons
Where do axons of the corticobulbar tract terminate?
motor nuclei of cranial nerves :)
How are axons and dendrites alike?
Axons and dendrites are both extensions of a neuron. They are involved in transmitting electrical signals within the nervous system. Axons carry signals away from the cell body, while dendrites receive signals from other neurons.
What pairs lists the fiber like extensions that are components of neurons a axons and myelin b synapses and myelin c dendrites and axons d dendrites and synapses?
C. Dendrites and axons both extend from the cell body of the neuron in a branching fashion.

Do they make extensions for fine hair?
yes (:
What are the two kinds of branches that extend from the cell body of a neuron what does each do?
The ones carrying the input are the dendrites, the ones carrying the output are the axons.

Which cells from the anterior gray horn are the only ones that terminate in skeletal muscle cells?
Axons from the anterior gray horn are the only ones that terminate in skeletal muscle cells. This principle of the final common path to skeletal muscles has important practical implications.
