What else can I help you with?
Are collections of neuron cell bodies associated with nerves in the PNS?
Yes, collections of neuron cell bodies associated with nerves in the peripheral nervous system (PNS) are known as ganglia. Ganglia can contain cell bodies of sensory neurons (dorsal root ganglia) or autonomic neurons (autonomic ganglia) that help relay information to and from the central nervous system.
Does the ganglia contain sensory neurons?
No, the ganglia are clusters of nerve cell bodies located outside of the central nervous system. They primarily contain motor neurons that transmit signals from the central nervous system to muscles and glands for motor control. Sensory neurons transmit signals from sensory organs to the central nervous system for processing.
What are some collections of nerve cell bodies found in a small number of locations outside the central nervous system are called?
Ganglia. Ganglia are collections of nerve cell bodies found outside the central nervous system, typically located along the peripheral nerves. They can be sensory ganglia (containing cell bodies of sensory neurons) or autonomic ganglia (containing cell bodies of autonomic neurons).
What are the bundles of unmyelinated axons dendrites and neuron cell bodies in the CNS from?
In the central nervous system (CNS), bundles of unmyelinated axons, dendrites, and neuron cell bodies are referred to as "gray matter." This gray matter primarily consists of neuronal cell bodies and their dendrites, which are involved in processing information. In contrast, myelinated axons, which facilitate faster signal transmission, form the "white matter" of the CNS. The organization of these structures is crucial for the overall function and connectivity of the nervous system.
Is the brain part of the Central Nervous System or the Peripheral Nervous System?
Central nervous system. In fact, the brain is the CENTER of the central nervous system.
Where do unmyelinated axons rest?
Unmyelinated axons rest within the nerve fibers of the peripheral and central nervous systems. In the peripheral nervous system, they are often found in small-diameter fibers, surrounded by Schwann cells that do not form myelin sheaths. In the central nervous system, unmyelinated axons are located in areas where oligodendrocytes provide support without myelination. These axons typically transmit signals more slowly than myelinated ones.
Collection of nerve cell bodies found outside CNS?
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
What does the central nervous systems contain?
brain and spinal cord

Does Concerta contain predazone?
No; Concerta contains a central nervous system stimulant known as methylphenidate.
Does skelatin contain aspirin?
No. It it purely a muscle relaxant, and works as a central nervous system depressant.
What is a disadvantage of unmyelinated nervous tissue when compared to myelinated tissue?
Unmyelinated tissue is substantially slower in conducting impulses along the axon. With myelinated axons, the action potential (impulse) jumps from node to node greatly increasing the speed of the impulse.
Does phentermine contain sulfur?
No, phentermine does not contain sulfur in its chemical structure. It is a stimulant that affects the central nervous system and is used for weight loss.
Does the ganglia contain sensory neurons?
No, the ganglia are clusters of nerve cell bodies located outside of the central nervous system. They primarily contain motor neurons that transmit signals from the central nervous system to muscles and glands for motor control.

Does the dorsal cavity contain the structures of the nervous system?
The dorsal cavity contains the spinal cord, which is part of the central nervous system. Every body cavity contains some structures of the nervous system.
