Write answer in between .Q:A 62-year-old man with prostate cancer comes to the physician because of low back pain for 2 weeks and a 4.5-kg 10-lb weight loss. Physical examination shows localized tenderness over the lumbar spine. An x-ray of the lumbar spine shows several osteoblastic lesions at the level of L2 and L4 vertebrae. Microscopic examination of a bone biopsy specimen from the L4 vertebra shows irregular bone trabeculae and star-shaped cells with long, cytoplasmic processes located deep within the lacunae. Exchange of nutrients and waste products between these cells most likely occurs through which of the following structures?? A: Macula adherens, B: Macula communicans, C: Zonula occludens, D: Hemidesmosomes, E: Zonula adherens,  <response>: This is a question about the microscopic anatomy and physiology of osteoblasts in bone. The patient has prostate cancer that has metastasized to his lumbar vertebrae. The x-ray and biopsy show osteoblastic lesions characteristic of prostate cancer bone metastases. The question asks about the structures that allow nutrient and waste exchange between the osteoblasts and surrounding tissue. Osteoblasts are star-shaped cells embedded in the bone matrix. The correct answer will be a structure that connects the osteoblasts to blood vessels or bone canaliculi to allow this exchange.B: Macula communicans
