Which of the Following Comparisons of the Innate and Adaptive

question 9

Multiple Choice

Which of the following comparisons of the innate and adaptive immune systems is FALSE?

• A) The innate immune system is more likely to recognize normal self, and therefore cause autoimmunity, than is the adaptive immune system.
• B) Receptors used for recognition in innate immunity are encoded in the germline, whereas those of the adaptive immune system are encoded by genes generated via somatic recombination of germline receptor gene loci.
• C) The innate and adaptive immune systems share some of the same effector mechanisms.
• D) Both the innate and adaptive immune systems can recognize nonmicrobial substances.
• E) The innate immune system does not have memory but the adaptive immune system does.

Definitions:

Nerve Impulse

An electrical signal that travels along a neuron, conveying information from one part of the body to another.

Resting Potential

The voltage difference between the inside and the outside of a neuronal membrane when the neuron is not firing.

Nerve Impulses

Electrical signals that travel along the dendrites and axons of neurons, enabling communication within the nervous system.

Unmyelinated Axons

Refer to nerve fibers that lack a myelin sheath, resulting in slower transmission of nerve impulses compared to myelinated axons.
