The largest formen in the human body is:
1. foramen magnum
2. foramen of Monro
3. obturator foramen
4. iter
One of the unpaired facial bones of the skull that takes part in the formation of the nasal septum is:
1. sphenoid
2. vomer
3. nasal bone
4. lacrimal bone
The largest ankle bone is:
1. cuboid
2. navicular
3. calcaneus
4. talus
A dense outer layer of vascular connective tissue enveloping the bones except at the surfaces of the joints is the:
1. epiphysis
2. diaphysis
3. articular cartilage
4. periosteum
What is number of bones in a human adult?
1. | 150 | 2. | 300 |

In an adult, erythropoeisis will be maximum in:
1. femur
2. sternum
3. humerus
4. tibia
When a bone bends and cracks, instead of breaking completely into separate pieces, the fracture is called as:
1. greenstick
2. incomplete
3. compound
4. simple
The critical event for the contraction of striated muscles would be that calcium ions:
1. | are released from troponin C |
2. | bind to tropomyosin |
3. | bind to troponin |
4. | are taken up by the sarcoplasmic reticulum |
All the following shorten during muscle contraction except:
1. sarcomere
2. A bands
3. I bands
4. H bands
Cross bridge formation during muscle contraction involves:
1. | troponin and actin | 2. | tropomyosin and myosin |
3. | myosin and troponin | 4. | myosin and actin |
