There are four components of the skeletal system
- bones,
- cartilage,
- tendons, and
- ligaments.
Your skeletal system provides: SUPPORT
Support: The bones of your vertebral column, pelvis, and legs hold up your body. The jawbone supports your teeth.
Your skeletal system provides: PROTECTION
Protection: The skull protects your brain. The vertebral column protects your spinal cord. The rib cage protects your heart and lungs.
Your skeletal system provides: BLOOD FORMATION
Blood formation: Bone marrow in many bones is the major producer of blood cells, including most of those in your immune system
Your skeletal system provides: MINERAL STORAGE & BALANCE
Mineral storage and balance: The skeletal system stores calcium and phosphorus and releases them when your body needs them for other purposes.
Your skeletal system provides: DETOXIFICATION
Detoxification: Bones remove metals like lead and radium from your blood, store them, and slowly release them for excretion.
Your skeletal system provides: ENDOCRINE GLANDS
Endocrine regulation: Bone cells release a hormone called osteocalcin, which increases insulin secretion and reduces stores of fat.
1 Long
Classification of Bones
The bones of your skeletal system are classified by their shape. Each falls into one of the following four shape categories:
•Long (considerably longer than they are wide), like the main bones of the limbs, palms, soles, fingers, and toes;
2 Short
Classification of Bones
The bones of your skeletal system are classified by their shape. Each falls into one of the following four shape categories:
Short (nearly as long as they are wide), like the patella (kneecap) and the bones of the wrists and ankles;
3 Flat
Classification of Bones
The bones of your skeletal system are classified by their shape. Each falls into one of the following four shape categories:
Flat, like the bones of the skull and the ribs;
4 Irregular
Classification of Bones
The bones of your skeletal system are classified by their shape. Each falls into one of the following four shape categories:
Irregular, like the vertebrae.
diaphysis
the shaft or central part of a long bone.
cortical bone
Cortical bone is the dense outer surface of bone that forms a protective layer around the internal cavity. This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion.
epiphysis
epiphysis
1.
the end part of a long bone, initially growing separately from the shaft.
2.
another term for pineal.
epiphysial plate
The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.
periosteum
a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
it protects the bone and anchors blood vessels and nerves to the bone’s surface
medulla
the inner region of an organ or tissue, especially when it is distinguishable from the outer region or cortex (as in a kidney, an adrenal gland, or hair).
Haversian canals.
any of the minute tubes which form a network in bone and contain blood vessels.

osteoporosis
One of the major bone diseases is osteoporosis, which results from a loss of bone density
More common in women than in men, the incidence of osteoporosis increases with age
osteopenia
reduced bone mass of lesser severity than osteoporosis.
Osteomyelitis:
an inflammation of bone and bone marrow caused by a bacterial infection, such as staphylococcus.
Osteomalacia:
a disease (known as rickets in children) caused by vitamin D deficiency where the calcium-lacking bones become soft and flexible, lose their ability to bear weight, and become bowed.
Achondroplasia:
a very rare condition where the long bones stop growing in childhood, but the axial skeleton bones are not affected (Figure 4.5). People with this condition are short in stature, with the average adult measuring about 4 feet tall. Although intelligence and life span are normal, the disease is caused by a spontaneous gene mutation that then becomes a dominant gene for succeeding generations.
Osteogenesis imperfecta (OI)
a rare genetic disorder producing very brittle bones that are easily fractured or broken, often in utero (while inside the uterus).
Primary bone cancer is found in three forms:
- Osteogenic sarcoma occurs most often in bone cells around the knee in adolescents.
- Ewing sarcoma occurs most often in children and adolescents.
- Chondrosarcoma arises in cartilage cells, often in the pelvises of older people.

scoliosis
abnormal lateral curvature of the spine.
Scoliosis occurs most often during the growth spurt just before puberty.
Most cases are mild with few symptoms. Some children develop spine deformities that get more severe as they grow. Severe scoliosis can be painful and disabling.
Often, no treatment is necessary. Sometimes a brace or surgery is needed.

A rheumatoid nodule is a local swelling or tissue lump, usually rather firm to touch, like an unripe fruit, which occurs almost exclusively in association with rheumatoid arthritis. Very rarely rheumatoid nodules occur as rheumatoid nodulosis in the absence of arthritis.
Your pelvic girdle
Your pelvic girdle consists of your two hip bones that articulate anteriorly with each other at the symphysis pubis and posteriorly with the sacrum (a triangular-shaped bone in your lower back). This forms the bowl-shaped pelvis. The two joints between your hip bones and the sacrum are called sacroiliac joints.
