Which type of cells develop from clonal selection of lymphocytes?
Clonal selection of lymphocytes leads to the development of specific effector cells and memory cells. When a lymphocyte recognizes a specific antigen, it proliferates and differentiates into effector cells, such as plasma cells that produce antibodies, or cytotoxic T cells that kill infected cells. Additionally, some of the activated lymphocytes become memory cells, which provide long-lasting immunity by responding more rapidly upon subsequent exposures to the same antigen.
What cells give rise to memory cells following the primary response?
Memory cells arise from B cells and T cells following a primary immune response. When these lymphocytes encounter their specific antigen, they undergo clonal expansion and differentiation, resulting in the formation of effector cells and a subset of long-lived memory cells. These memory cells persist in the body and enable a quicker and more robust response upon subsequent exposures to the same antigen.
What two roles does a T cell play after it divides?
After a T cell divides, it primarily takes on two roles: effector T cells and memory T cells. Effector T cells actively respond to infections by recognizing and attacking infected cells or coordinating the immune response. Memory T cells, on the other hand, persist long-term in the body, providing a faster and more efficient response if the same pathogen is encountered again in the future. This dual function is crucial for both immediate defense and long-term immunity.
What do Mature B cells do?
Mature B cells are responsible for producing antibodies, which are proteins that help the immune system recognize and fight off pathogens like bacteria and viruses. These cells can also develop into memory B cells, which provides long-lasting immunity against previously encountered pathogens.
How long do lymphocytes live?
Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.
How do memory cells differ from effector cells?
Memory cells are long-lived cells that "remember" specific pathogens and help mount a faster and stronger immune response upon re-exposure. Effector cells, on the other hand, are specialized cells that actively participate in the immune response by directly eliminating pathogens. Memory cells are part of the adaptive immune system, while effector cells can be part of both the innate and adaptive immune responses.
In the reflex arc the muscle or gland that responds to a motor impulse is called?
Effector. Memory Aid = The Effector really should be called the Effectee, since it's the one getting effected. Its cheesey but helped me memorize it...
What do t cells do?
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
Does memory effect your maturity level?
Memory does effect your maturity level, example: If you don't remember much than you start acting immature, like acting out in public. -Christine Forte
What are the 3 types of cells that helper t cells produce upon being alarmed of an antigen?
Helper T cells can produce three types of cells when alerted to an antigen: effector T cells, memory T cells, and regulatory T cells. Effector T cells help eliminate the antigen, memory T cells remember the antigen for future responses, and regulatory T cells help regulate the immune response to prevent excessive inflammation.

Who has better memory children or adolts?
The retention and recall of memory varies widely in these two age groups. Children can retain more because their brain is 'new,' but a young adult has the absolute best memory because their brains are fully mature.

Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells

Muscles and glands?
In terms of the nervous system, muscles and glands are given the generic term effector organs. Impulses are picked up from receptors, which then travel to the brain, which sends orders along the motor neurons to these effector organs. In the case of reflex actions, however, the brain is not involved, and the process is done much faster as a result.
