How do vaccines work? Do they work against viruses and bacteria? Why there<br> are so many vaccines.
Liono4ka [1.6K]

Answer:

Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick. Live, attenuated vaccines fight viruses and bacteria. These vaccines

contain a version of the living virus or bacteria that has been weakened

so that it does not cause serious disease in people with healthy immune

systems. Because live, attenuated vaccines are the closest thing to a

natural infection, they are good teachers for the immune system.

Examples of live, attenuated vaccines include measles, mumps, and

rubella vaccine (MMR) and varicella (chickenpox) vaccine. Even

though they are very effective, not everyone can receive these vaccines.

Children with weakened immune systems—for example, those who are

undergoing chemotherapy—cannot get live vaccines. Those are only some vaccines, of course not all vaccines inject a live virus into your body. And of course, there are so many vaccines because (unfortunately) there are so many diseases!

How are dendrites synthesized in a neuron?
hram777 [196]

Answer:

The processing power of the mammalian brain is derived from the tremendous interconnectivity of its neurons. An individual neuron can have several thousand synaptic connections. While these associations yield computational power, it is the modification of these synapses that gives rise to the brain's capacity to learn, remember and even recover function after injury. Inter-connectivity and plasticity come at the price of increased complexity as small groups of synapses are strengthened and weakened independently of one another (Fig. 1). When one considers that new protein synthesis is required for the long-term maintenance of these changes, the delivery of new proteins to the synapses where they are needed poses an interesting problem (Fig. 1). Traditionally, it has been thought that the new proteins are synthesized in the cell body of the neuron and then shipped to where they are needed. Delivering proteins from the cell body to the modified synapses, but not the unmodified ones, is a difficult task. Recent studies suggest a simpler solution: dendrites themselves are capable of synthesizing proteins. Thus, proteins could be produced locally, at or near the synapses where they are needed. This is an elegant way to achieve the synapse specific delivery of newly synthesized proteins.

What layer of a bone lines the medullary cavity?
vagabundo [1.1K]

Answer:

Endosteum

Explanation:

The hollow region in diaphysis is known as medullary cavity which is filled with the yellow marrow.

<u>The endosteum is the thin vascular membrane of the connective tissue which lines up inner surface of bony tissue which forms medullary cavity of the long bones.</u>

Endosteal surface is reabsorbed usually during the long periods of malnutrition and thus resulting in the less cortical thickness.
