Answer:
The correct answer is A.
Explanation:
An osteoclast is large multinucleated cell present in the bone. Its main function is bone resorption, which occur when the osteoclasts secret hydrogen ions and many enzymes. As a result, bone matrix is digested by them. The most important enzyme is the protease cathepsin K, which degrades collagen.
Cathepsin K is regulated by parathormone, calcitonin and growth factor interleukin 6.
Matrix digestion is key during <u>bone fractures</u>, because it allows the repair and remodeling of the bone. But when this action is excessive, it can lead to osteoporosis (loss of bone density).
Answer:
The correct answer is -
nucleus - reproduction, mitochondria- reproduction, golgi apparatus - waste production, endoplasmic reticulum - growth, ribosomes - growth, lysosomes- waste production, vacuoles - growth, cell membrane - interaction with the environment, chloroplast - uses energy, cell wall - interaction with the environment
Explanation:
A Cell has various organelles with more than one generic function such as the nucleus not just play role in cell reproduction but also plays role in regulating other organelle and cell growth by transcription. Mitochondria produces and provides energy for many functions such as growth, reproduction and substance transport.
Golgi apparatus package proteins and wastes to transfer them out of the cell. The ndoplasmic reticulum modifies the protein produced by ribosomes and helps in growth of the cell. Lysosomes digest waste and cell debris by lysosomal vesicles. Cell membrane and cell wall interact with outer environement.

This is a case of a patient that needs his subtalar joint to be immobilized by the fusion of supporting bones. This is called arthrodesis and the corresponding CPT code for arthrodesis procedures in the foot and toes is CPT 28715. The patient also underwent bone grafting from the fibula to fill in the defects in the talus. The CPT code for general grafts or implants procedures in the musculoskeletal system is CPT 20902-51.
