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.

Cytoplasmic extensions of neurons that act as an antennae for the reception of nerve impulses from what other nerve cells?
Cytoplasmic extensions of neurons that act as an antennae for the reception of nerve impulses from other nerve cells are called dendrites. Dendrites receive signals from other neurons and transmit these signals to the cell body of the neuron.
What cytoplasmic projections of a neuron receive information?
The cytoplasmic projections of a neuron that receive information are called dendrites. Dendrites are branch-like extensions that increase the surface area available for synaptic contacts with other neurons, allowing them to receive chemical signals and transmit electrical impulses toward the cell body. These structures play a crucial role in processing and integrating incoming signals, contributing to the overall function of the neuron.
What are extensions of a neuron that receive signals?
Dendrites are the extensions of a neuron that receive signals from other neurons. They are responsible for transmitting electrical impulses towards the cell body of the neuron.
The combination of a neuron and the muscle fibers it associates with is called?
The combination of a neuron and the muscle fibers it associates with is called a motor unit. Motor units work together to produce movement by having the neuron stimulate the muscle fibers it innervates to contract.
Fatty covering material of neuron fibers?
Yelin
Do schwann cells wrap their cytoplasmic extensions around thick neuron fibers in the CNS?
NO they wrap around the axon in the PNS!
What are cytoplasmic extensions that carry nerve impulses towards the cell body of a neuron?
The extension from a nerve cell that carries impulses toward the nerve is a dendrite

The sheath around some neuron fibers that aids in regeneration?
neurilemma
What are the two types of fibers that project from a neuron's cell body?
The two fibers that a neuron has are the nerve and the myelin fibers
What are the extensions of the cell body?
The extensions of the neuron cell body (soma) are called dendrites. Refer to the related link below for an illustration of a neuron.

What is the difference between a motor unit and a motor neuron in the context of muscle movement?
A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
A motor neuron transmits signals to?
Muscle fibers
Fatty covering material of neuron fibers?
Yelin
