Muscles, ligaments, cartilage, and tendons, rather than bones, are the most common shoulder injuries. Rotator cuff tears, shoulder impingement, and dislocation are all common shoulder injuries. Shoulder injuries are most common in athletes, such as tennis or football players, and people who work in jobs that require regular, intense, over-head lifting.
The shoulder is necessary for arm movement, so it’s essential for most daily activities like driving and cooking. The arms will move up and down, side to side, forward and backward, and execute reaching motions with a healthy shoulder.
Articular cartilage in the shoulder is typically thinner than in weight-bearing joints like the knees and hips. When the articular cartilage in the shoulder is weakened, the shoulder’s ability to withstand friction and impact is greatly diminished.

The mineral salts mainly consist of hydroxyapatite, a calcium phosphate mineral. Calcification is the crystallization and hardening of tissue caused by the accumulation of mineral salts on the collagen fiber matrix. Calcification can only take place in the presence of collagen fibers.
Long bones have a shaft and two ends and are longer than they are wide. Bone marrow is contained in a marrow cavity in the diaphysis, or central shaft. The epiphyses are the rounded ends of the bones that are coated in articular cartilage and filled with red bone marrow that contains blood cells (Figure 19.17). Long bones, such as the femur, tibia, ulna, and radius, make up the majority of the limb bones. The patella, as well as the bones of the wrist and ankle, are exceptions.
Short bones, also known as cuboidal bones, have the same width and length, forming a cube-like shape. The bones of the wrist (carpals) and ankle (tarsals), for example, are small bones (Figure 19.16).
Flat bones are thin and relatively wide bones that are found where substantial organ defense or broad muscle attachment surfaces are needed. The sternum (breast bone), ribs, scapulae (shoulder blades), and the roof of the skull are all flat bones (Figure 19.16).

What does bone marrow actually do?

Bone, also known as osseous tissue, is a rigid, dense connective tissue that makes up the majority of the adult skeleton, the body’s support system. Cartilage, a semi-rigid type of connective tissue, offers flexibility and smooth surfaces for movement in areas of the skeleton where bones move (for example, the ribcage and joints). The skeletal system, which is made up of bones and cartilage, is responsible for the following vital functions in the human body:
The gross functions of the skeletal system—those that can be observed—are the most visible. You can see how the bones help, promote movement, and secure the human body just by looking at them.
The bones and cartilage of your skeletal system act as a scaffold to support the rest of your body, just as the steel beams of a building do to support its weight. You’d be a limp mass of organs, tissue, and skin if you didn’t have a skeletal system.
Bones also help you move by acting as attachment points for your muscles. While some bones only serve to sustain your muscles, others also transmit the forces produced as they contract. Bones serve as levers and joints serve as fulcrums in mechanical terms ((Figure)). A bone can not move until a muscle spans a joint and contracts. Look for more information on the musculoskeletal system, which is the relationship of the skeletal and muscular systems.

Osseous tissue (bone tissue) is unlike any other tissue in the body. Bone is a hard substance, and many of its functions are dependent on it. Bone is versatile in the sense that its form changes to accommodate stresses, as we’ll see later in this chapter. This section will first look at the gross anatomy of bone before moving on to its histology.
The diaphysis and epiphysis are the two major regions of a long bone (Figure 6.3.1). The diaphysis is a hollow, tubular shaft that connects the bone’s proximal and distal ends. The medullary cavity is located inside the diaphysis and is filled with yellow bone marrow in adults. The diaphysis’ outer walls (cortex, cortical bone) are made up of thick and hard compact bone, which is a form of osseous tissue.
The epiphysis (plural = epiphyses) is the broader portion of the bone at each end that is filled with spongy bone, another form of osseous tissue. In certain long bones, red bone marrow fills the gaps between the spongy bones. At the metaphysis, each epiphysis meets the diaphysis. The epiphyseal plate, which is the site of long bone elongation mentioned later in the chapter, is found in the metaphysis during development. The epiphyseal plate becomes an epiphyseal line when the bone begins developing in early adulthood (approximately 18–21 years).
