🔺 The femur is the longest and strongest bone, designed to support body weight and enable movement. 🔺 Its ends, the proximal and distal epiphyses, contain spongy bone that reduces stress and holds red marrow. 🔺 The diaphysis or shaft consists of dense compact bone providing strength and rigidity. 🔺 The medullary cavity stores yellow marrow, an energy reserve made of fat cells. 🔺 The periosteum covers the bone externally, nourishing it and aiding repair. 🔺 Articular cartilage ensures smooth

SPONGY BONE is the deep, more porous region of bone tissue. Spongy bone is also known as trabecular bone (trabeculae = little beams) due to the tiny beams of bone tissue that make up the “spongy” architecture. . . Spongy bone is always covered with a layer of compact bone for added protection. The little beams, trabeculae, of spongy bone may appear unorganized, but make no mistake the trabeculae are organized in the lines of stress, which helps bone resist the forces placed upon it. . .
