Growth hormone, testosterone and thyroid hormone allafet by: promoting lengthening of long bones by acting on epiphyseal canilage stimulating long bone width by promoting bone appositional growh triggering the closure of the epiphysis by killing the inhibiting osteociast activity 49. Compared to compact bone, spongy bone lacks which of the folowing osteoid osteons canalicui lamellae periosteum endosteum promoting lengthening of long bones by acting on epiphyseal cartilage stimulating long bone width by promoting bone appositional growth triggering the closure of the epiphysis by killing the chondrocytes inhibiting osteoclast activity while stimulating osteoblast activity 50. Estrogen affects bone maintenance by:Explanation / Answer
48. Growth hormone, testosterone and thyroid hormone affect skeletal development by inhibiting osteoclast activity and promoting osteoblast activity.
Hence option " inhibiting osteoclast activity" is correct.
49. Osteons are the basic units of compact bone, which are absent in cartilage bones.
Hence option"Osteons" is correct.
50. Estrogen is a female hormone which affects bone maintenance by inhibiting osteoclast activity and by stimulating osteoblast activity.
Hence option"inhibiting osteoclast activity while stimulating osteoblast activity" is correct.
