Statement I: | Locomotory structures need not be different from those affecting other types of movements. |
Statement II: | All movements are locomotions but all locomotions are not movements. |
Which of the following movements can be seen in a human body?
I. Amoeboid | II. Ciliary | III. Flagellar |
1. | I and II only | 2. | I and III only |
3. | II and III only | 4. | I, II and III |
Cells of human body exhibit three main types of movements. Cytoskeleton elements called microfilaments play an important role in:
A. Amoeboid movements
B. Ciliary movements
C. Muscular movements
1. | Only A | 2. | Only A and B |
3. | Only A and C | 4. | A, B and C |
I: | Macrophages in body and leucocytes in blood exhibit amoeboid movement. |
II: | Passage of ova through the female reproductive tract is facilitated by the ciliary movement. |
III: | Human sperm moves with the help of flagellum |
I: | Amoeboid |
II: | Ciliary |
III: | muscular |
I: | removing dust particles and some of the foreign substances inhaled along with the atmospheric air. |
II: | passage of urine in the collecting duct of the nephron. |
III: | passage of ova through the female reproductive tract |
I: | is derived from embryonic endoderm |
II: | constitutes about 40-50 percent of human body |
