A colorful image depicting a variety of healthy foods. The arrangement includes a woven basket filled with fresh vegetables such as carrots, broccoli, bell peppers, and leafy greens. Surrounding the basket are additional food items including fish, cuts of meat, eggs, and bottles that appear to contain oil or juice. The image is rich in color and detail, showcasing a balanced and nutritious selection of food.
آلية تشكيل العظام
A biological diagram illustrating the mechanism of bone formation and remodeling. The diagram shows a section of bone (white, elongated structure) and various types of cells involved in its maintenance and repair.
**Key Components and Labels (from right to left, top to bottom):**
* **Top-right:** Several small, multi-nucleated cells labeled 'ما قبل هادمة العظم' (Pre-osteoclast). These cells are roundish with multiple nuclei and some red dots, indicating precursors.
* **Middle-right:** A larger, irregular-shaped cell with multiple nuclei, actively engaged with the bone surface, labeled 'ناقضة عظمية متعددة النوى' (Multi-nucleated osteoclast). This cell appears to be resorbing bone.
* **Below the middle-right osteoclast:** Text 'تنشيط ناقض العظم' (Osteoclast activation) pointing to the activity of the osteoclast on the bone surface.
* **Bottom-right:** A segment of bone tissue, depicted as a white, elongated structure.
* **Bottom-left:** A cluster of yellow, cuboidal cells on the bone surface, labeled 'بانيات العظم' (Osteoblasts). These cells are shown forming new bone matrix.
* **Below the osteoblasts:** Another cluster of yellow, multi-nucleated cells on the bone surface, labeled 'هادمة العظم متعددة النوى تنشيط هادم العظم' (Multi-nucleated osteoclast, osteoclast activation). This represents active bone resorption.
* **Top-left:** Several smaller, round cells, some with multiple nuclei, labeled 'أستيوكلاست' (Osteoclast). These cells are shown with red dots, possibly indicating signaling molecules or precursors.
**Process Flow (indicated by arrows):**
* Arrows connect 'ما قبل هادمة العظم' (Pre-osteoclast) to the larger 'ناقضة عظمية متعددة النوى' (Multi-nucleated osteoclast), illustrating differentiation or maturation.
* Arrows also connect 'أستيوكلاست' (Osteoclast) cells to 'بانيات العظم' (Osteoblasts) and the active osteoclast clusters, suggesting complex cellular interactions and signaling pathways involved in regulating bone remodeling.

--- VISUAL CONTEXT ---
**IMAGE**: Untitled
Description: A colorful image depicting a variety of healthy foods. The arrangement includes a woven basket filled with fresh vegetables such as carrots, broccoli, bell peppers, and leafy greens. Surrounding the basket are additional food items including fish, cuts of meat, eggs, and bottles that appear to contain oil or juice. The image is rich in color and detail, showcasing a balanced and nutritious selection of food.
Context: This image visually supports the question about the importance of healthy eating habits for maintaining a healthy skeletal system.
**DIAGRAM**: آلية تشكيل العظام

Context: This diagram illustrates the cellular roles of osteoblasts (bone-forming cells) and osteoclasts (bone-resorbing cells) in bone remodeling, directly addressing the comparison question in 'نشاط (4-3)'.
