Are axons most located and protected within the CNS?
axons
What are the three types of neuron?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
What cell cell that myelinates and insulates axons within the CNS is the?
Oligodendrocyte
What nervous system cell act as phagocytes within the central nervous system?
Both Macrophages and leukocytes act as phagocytes within the CNS
Do astrocytes provide the defence for the CNS?
Astrocytes play a crucial role in the defense of the central nervous system (CNS) by providing structural support, maintaining the blood-brain barrier, promoting neuronal repair, and modulating immune responses. They also help regulate the extracellular environment by clearing neurotransmitters and metabolic waste products. Overall, astrocytes contribute to the defense and maintenance of the CNS through their diverse functions.
Are axons most located and protected within the CNS?
axons
Which glial cells provide structural metabolic support for neurons?
CNS = Oligodendrocytes PNS = Schwann cells
What is mostly located and protected within the CNS?
axons
Which neuron is located entirely within the cns?
interneurons
A fiber tract that provides for communication between different parts of cns is called?
Neuron
What is a bundle of nerve processes inside the CNS?
The usual name for a bundle of nerve processes within the CNS is "tract" or "fasciculus"
What are 3 types of neurons?
Sensory neurons: Transmit sensory information from the body to the brain. Motor neurons: Control muscles and glands, enabling movement and bodily functions. Interneurons: Process information within the central nervous system, facilitating communication between sensory and motor neurons.

Is there nuclei inside the CNS?
Yes and there is genetic material within the nuclei.
What is the general name for all support cells within the CNS?
Neuroglia
Is regeneration within the CNS more successful than with PNS?
YES
What cell cell that myelinates and insulates axons within the CNS is the?
Oligodendrocyte
