What is the function of the central nervous system?
Transmit information to and from the brain
Control reflex activities
Receive and process information
Produce CSF within brain ventricles
Which part of the nervous system conducts signals to and from the brain?
Spinal cord
Astrocytes
Schwann cells
Microglia
What is the function of efferent nerves?
Tell the body how it is being affected by stimuli
Stimulate muscles to produce effort
Absorb and dispose of dead cells and bacteria
Wrap around nerve fibers and produce myelin
Which type of glial cell forms a protective covering around the spinal cord and central cavities within the brain?
Astrocytes
Microglia
Ependymal cells
Oligodendrocytes
What is the function of Schwann cells in the peripheral nervous system?
Form fatty myelin sheaths around nerve fibers
Serve as cushioning support cells
Link nutrient-supplying capillaries to neurons
Absorb and dispose of dead cells and bacteria
Which part of a neuron carries impulses away from the soma to the axon terminals?
Dendrites
Myelin sheath
Axon
Axon terminals
What is the function of the myelin sheath?
Absorb and dispose of dead cells and bacteria
Wrap around nerve fibers and produce myelin
Serve as cushioning support cells
Carry impulses away from the soma to the axon terminals
Which type of neuron carries impulses from the skin and organs to the spinal cord and brain?
Sensory (afferent) neurons
Motor (efferent) neurons
Interneurons
Anaxonic neurons
What is the structure of bipolar neurons?
One axon and one dendrite
Multiple dendrites
Single axon with dendrites on the peripheral end
One axon and multiple dendrites
Which type of neuron has one axon and multiple dendrites?
Sensory (afferent) neurons
Motor (efferent) neurons
Interneurons
Multipolar neurons
What is the function of the myelin sheath in a neuron?
It speeds up the transmission of electrical impulses
It slows down the transmission of electrical impulses
It generates electrical impulses
It stops the transmission of electrical impulses
What is the role of afferent nerves in the nervous system?
They carry messages from the brain and spinal cord to the muscles
They carry messages from the sensory organs to the brain and spinal cord
They provide support and nutrition to the neurons
They form the myelin sheath around nerve fibers
What is the function of oligodendrocytes in the central nervous system?
They form the myelin sheath around nerve fibers
They serve as cushioning support cells
They link nutrient-supplying capillaries to neurons
They absorb and dispose of dead cells and bacteria
What is the role of Astrocytes in the nervous system?
They form a protective covering around the spinal cord
They help in transmitting information to and from the brain
They provide structural support and regulate the external environment of neurons
They produce cerebrospinal fluid (CSF)
What is the function of Schwann cells in the nervous system?
They conduct signals to and from the brain
They wrap around nerve fibers and produce myelin in the peripheral nervous system
They absorb and dispose of dead cells and bacteria
They produce cerebrospinal fluid (CSF)
