खालील विमाने विचारात घ्या : अ. मानवी सांगाड्यात पाच प्रकारची हाडे असतात. ब. वजनाला आधार देणे आणि हालचाली सुलभ करणे ही लांब हाडांची (Long bones) कार्ये आहेत. क. स्नायुबंदांना दबावापासून वाचविणे हे सपाट हाडांचे (Flat bones) कार्य आहे.
(a)मानवी सांगाड्यात पाच प्रकारची हाडे असतात. / There are five types of bones in the skeleton.
(b)वजनाला आधार देणे आणि हालचाली सुलभ करणे ही लांब हाडांची (Long bones) कार्ये आहेत. / The function of the long bones is to support weight and facilitate movement.
(c)स्नायुबंदांना दबावापासून वाचविणे हे सपाट हाडांचे (Flat bones) कार्य आहे. / The function of the flat bones is to protect tendons from stress.
Long bones support weight and facilitate movement, while flat bones protect internal organs. Statement a is incorrect because human skeletons have more or different classifications depending on context, making statements a and b or a and c combinations tricky, but option 1 is the officially accepted answer.
खालीलपैकी कोणते विधान सत्य आहे? / Which of the following statements is true ?
(a)मानवी शरीरामध्ये एकूण 208 हाडे असतात. / The adult human skeleton consists of 208 bones.
(b)ममके आणि चेहऱ्याची हाडे हे अनियमित हाडांची उदाहरणे आहेत. / Vertebrae and facial bones are irregular type of bones.
An adult human skeleton consists of 206 bones (not 208, making statement 'a' false). Vertebrae and facial bones are irregular bones (making statement 'b' true).
