Answer:
The correct answer is b. Immunogens
Explanation:
Immunogens are the antigens that can trigger the immune response in the body once gets inside the body. Any antigen having capacity to excite a immune response against them is called immunogens but not every antigen is immunogen.
An antigen is called immunogen when it has some characteristic features like foreignness, high molecular weight and chemical complexity. An immunogen can initiate both innate and adaptive immune response. Adaptive immune response is memory based and very specific for any particular immunogen.
Some common immunogens are: bacteria, virus, drugs, chemicals, dust, toxins.
Answer:
1. dendrite = directs impulses toward the soma.
2. axon = conducts impulses toward the synaptic terminal.
3. perikaryon = region surrounding nucleus.
4. collateral branches = main branches of an axon.
5. synaptic terminal = enlarged end of an axon.
6. synaptic vesicles = contains neurotransmitters.
7. axon hillock = connects the cell body and axon.
8. Nissl bodies = clusters of RER and free ribosomes.
9. telodendria = fine branches of an axon.
10. myelinated internode = part of axon covered by Schwann cell.
11. neurilemma = Schwann cell's plasma membrane.
12. axolemma = membrane of the axon.
13. astrocyte = Forms the blood-brain barrier.
14. cell body = soma.
Answer:
The given statement is TRUE
Explanation:
Urinary bladder is the hollow, muscular and distensible (elastic) organ in the urinary system of a human. The urine enters the bladder through the ureters from the kidneys. The urine collected in the bladder expands it.
The urinary bladder is made up of transitional epithelium. Once the urinary bladder is expanded to a certain extent it stimulates the stretch receptors in the transitional epithelium for the excretion of urine through the urethra.
Therefore, when the urine is accumulated in the urinary bladder, the bladder distends or expands and stimulates the stretch receptors in the transitional epithelium for urine excretion.
