Articular cartilage Epiphysis Epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

The inner portion of bone, termed the medullary canal, is made up of cancellous bone. Bone marrow is located within the medullary canal and is interspersed between the trabeculae. Articular cartilage Epiphysis Epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Outer layer of bone Articular cartilage Epiphysis Epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Diaphysis of a long bone refers to the shaft portion and is the primary site of ossification Articular cartilage Epiphysis Epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Spongy bone Epiphysis refers to the expanded end portion and is the secondary site of ossification Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Epiphyseal line is epiphyseal closure, the epiphyseal plate, as it is known, ossifies or hardens and turns into an epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Periosteum is a fibrous membrane that encloses all of the bone except the joint surfaces and is crucial to supplying blood to the underlying bone Articular cartilage Epiphysis Epiphyseal line Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Endosteum is a thin layer of connective tissue that lines the surface of the bony tissue that forms the medullary cavity of long bones Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints Spongy bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Spongy bone Spongy bone forms a latticework, with interstices filled with embryonic connective tissue or bone marrow. Also called cancellous bone. Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis

Articular cartilage Epiphysis Epiphyseal line Spongy bone Nutrient foramen is the external opening for the entrance of blood vessels in a bone Medullary cavity Nutrient foramen Diaphysis Endosteum Periosteum Articular cartilage Epiphysis
