What are Large bundles of axons and dendrites make up called?
Large bundles of axons and dendrites are called nerves or tracts depending on their location in the central or peripheral nervous system.
Large bundles of axons and dendrites visible to the unaided eye are?
Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
What are bundles of fibers that connect the CNS with the rest of the body?
Bundles of fibres running between the Central Nervous System (CNS) and all the tissues of the body are called Nerves. These nerves make up the Peripheral Nervous System (PNS). The correct name for the fibres in these bundles is Axons which are the long part of neuron cells carrying the signal from the cell body to the Target Tissue.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What are Large bundles of axons and dendrites make up called?
Large bundles of axons and dendrites are called nerves or tracts depending on their location in the central or peripheral nervous system.
What is the name for bundles of myelinated axons in the PNS?
The name for bundles of myelinated axons in the peripheral nervous system (PNS) is "nerves." Nerves serve the purpose of transmitting sensory information and motor impulses between different parts of the body and the central nervous system.
Large bundles of axons and dendrites visible to the unaided eye are?
Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
What is a group of axons and dendrites of many neurons?
A group of axons and dendrites from many neurons is known as a nerve. In the peripheral nervous system, these bundles are often encased in protective tissues and are responsible for transmitting signals between the central nervous system and various parts of the body. In the central nervous system, similar collections are referred to as tracts. Both structures play crucial roles in facilitating communication within the nervous system.
Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.

Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What are the Ascending pathways of the central nervous system composed of?
The Ascending pathways of the central nervous system is made of "White Matter." (Vast amount of Axons coated with a sheath of Myelin)
Are axons efferent or afferent?
They can be both. Afferent axons carry (sensory) information toward the central nervous system; efferent axons carry (motor command) information away from the central nervous system towards the muscles and glands. Think "affect" vs. "effect" or "arrive" vs. "exit".
What moves across axons in the nervous system?
Electrical impulses move across axons in the nervous system.
What are 2 main parts of nervous system?
The central nervous system (CNS) and the peripheral nervous system (PNS)
Can oligodendrocytes myelinate several axons?
Yes, oligodendrocytes in the central nervous system can myelinate multiple axons simultaneously. This is in contrast to Schwann cells in the peripheral nervous system, which typically wrap around and myelinate only one axon.
