BIOL215 Lecture Week 06 Objective Assignment Chapter 6: Bone and Bone Tissue Bone Structure 1) Describe the gross anatomy of a typical long bone and flat bone. Indicate the locations and functions of red and yellow marrow, periosteum, and endosteum. i) Long Bone - Long bones are longer than they are wide, have two epiphyses and a diaphysis. All of the bones of the limbs, except the patella, ankle, and wrist, are considered long bones. A long bone has a shaft, the diaphysis, and two ends, the epiphyses. The periosteum is the outer surface of bone and covers a long bone in all areas, except for the articular surfaces, which are covered by articular, or hyaline, cartilage. Deep in the periosteum is a layer of compact bone, a thicker layer in the diaphysis than the epiphysis. The endosteum is a thin layer of connective tissue, which lines the surface of the bony tissue that forms the medullary cavity of long bones. In an adult, it contains yellow bone marrow. In the epiphyses deep to the layer of compact bone is spongy bone. Between the trabecula of the spongy bone is red bone marrow. ii) Flat Bone - Flat bones are thin, flattened, and a bit curved. The sternum, scapulae, ribs, and most of the bones of the skull are flat bones. Ossification, or osteogenesis, is the process of bone formation. Two mechanisms form bone: intramembranous and endochondral.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
