Questions for Dental School Prep
1. Describe the role of IgG in the immune response and how it contributes
to the body's defense mechanisms.
IgG is responsible for the allergic response and does not interact
with pathogens.
IgG plays a crucial role in the immune response by neutralizing
pathogens and facilitating their destruction by other immune
cells.
IgG is involved in the production of antibodies against self-
antigens.
IgG is primarily involved in the initial response to infections and
does not provide long-term immunity.
2. Describe the significance of IgD in the context of B cell activation.
IgD helps in the formation of antibodies by T cells.
IgD is responsible for the destruction of infected cells.
IgD is primarily involved in neutralizing toxins in the bloodstream.
IgD serves as a receptor on B cells, playing a crucial role in
their activation and differentiation.
3. How does the absence of an acrosome affect the functioning of the
sperm?
the sperm becomes non-motile
the sperm dies immediately after ejaculation
the sperm lacks progressive movement
, the sperm loses its ability to stimulate uterine motility at the time
of intercourse
