The Skeletal System
- The cartilage of the body is found in the nose, ear, and all the joints between each bone. The cartilage is very slick, and helps in the case of the bones rubbing against each bone.
-Tendons are the main protein found in connective tissue in the body. Endomysium, the innermost connective tissue that surrounds muscle, is primarily collagen. Tendons are found at the origin and insertion points of skeletal muscle.
-The skeletal system provides support to the body, protection to internal organs and aids in movement in conjunction with the muscular system. Bones, ligaments and cartilage are structural components of the system.
Cooperation with other Systems
The skeletal system and the respiratory system appear to be unrelated to each other. The skeletal system consists of hard bones, while the respiratory system consists of fragile lungs and a passageway by which air reaches them. But the one system could not exist without the other because the the respiratory system needs the protection of the skeletal system to function.
The digestive system interacts with the skeletal system by providing the phosphorus which helps bones and teeth. Calcium helps bones and teeth too. The skeletal system holds the digestive system, which is the frame of the whole body.
The kidneys are involved in calcium homestasis. When plasma calcium is low, the parathyroid glands signal the kidneys to increase calcium reabsorption, & also trigger the release of calcium from the bones. When plasma calcium is high, the kidneys excrete more calcium.
Basically, the skeleton is a frame. The muscles are attached to the frame by tendons. We flex out muscles and it moves our frame, creating movement!
Fact 1: The shoulder is like
a part of a video game
controller to move around
a character; that allows
the shoulder to move around
in most directions
Fact 2: You
r knee and lower
leg is like a
light switch, down
to bend, up
Fact 3:Without cartilage, our bones
would feel EXTREMELY
painful, and we wouldn't
have ears or the ends
of our noses (for example, our faces would look somewhat like Voldemort)
Did you know?
6 Major Functions
Blood cell production
The skeletal system is surrounded by soft tissue- except for the ribs and sternum that protect the heart and lungs and the skull which protects the brain.
The skeletal system provides structural support for the entire body.
Skeletal muscle is attached to bone so it pulls on the bone creating movement.
Its basic function is to store calcium and phosphorus--minerals that are released into the blood when needed.
Red bone marrow produces red blood cells, white blood cells and other blood elements.
In addition, The skeletal system is in charge of storing minerals and lipids(fats) (the yellow marrow, found in long bones, stores fat)
There are five different types of bones in the human body: long bones, short bones, flat bones, irregular bones, and sesamoid bones.
Long bones are not really long-well, some are- they just have to be longer than they are wide. That means Phalanges, the tips of your fingers, are also long bones.
Short bones, on the other hand, are as long as they are wide and mainly provide stability without moving.
Flat bones , like the sternum or scapula, serve to protect the soft vital organs beneath.
Irregular bones do not fall into any other category, as they are not uniform in shape (like the vertebrae).
Sesamoid bones are usually small and irregular, and they are mostly imbedded in a tendon, like the patella (knee cap). It's function is to protect the tendon,
The difference between male and female skeletons is that the female have a more rounded pelvis
The entire female body completes their development sooner than a male does. Females
complete their development around age 18, while males continue to mature until age 21.
Types of bones in the humans skeletal system (differences)
A new born baby has 300 bones, and an adult has 206 bones. As you grow up, your bones fuse together making some of them only one whole bone.
The skeleton protects many vital organs:
The skull protects the brain, the eyes, and the middle and inner ears.
The vertebrae protect the spinal cord.
The rib cage, spine, and sternum protect the human lungs, human heart and major blood vessels.
The clavicle and scapula protect the shoulder muscles.
The ilium and spine protect the digestive and urogenital systems and the hip.
The patella and the ulna protect the knee and the elbow respectively.
The carpals and tarsals protect the wrist and ankle respectively.
THE MOST IMPOTANT THING TO DO IN CARING FOR YOUR BONES IS EATING RIGHT AND EXERCISING ENOUGH.
BONES LOSE MASS NATURALLY THROUGH AGING, SO BUILD UP A LOT OF IT WHILE YOU’RE YOUNG. YOU CAN DO THIS BY TAKING IN SUFFICIENT AMOUNTS OF VITAMINS A, C, AND D, USUALLY FOUND IN CITRUS FRUITS, APPLES, SPINACH, AND BROCCOLI. ALSO, HAVE A LOT OF CALCIUM. THIS COMES FROM DAIRY PRODUCTS SUCH AS MILK, CHEESE, AND YOGURT. ALSO, PROTEIN ISN’T JUST FOR BUILDING MUSCLE. CONSUMING A LOT OF PROTEIN FROM LEAN MEATS, EGGS, AND MILK CAN HELP TAKE CARE OF BONES.
WEIGHT BEARING EXERCISES WILL HELP KEEP BONES STRONG, SO THEY DON’T BREAK AS YOU AGE. THESE EXERCISES IN CLUDE RUNNING, WALKING, CIRCUIT TRAINING, DANCING, AND STAIR CLIMBING.
AVOID BREAKING OR INJURING YOUR BONES BY WEARING PROTECTIVE GEAR DURING SPORTS (I.E. KNEE PADS, HELMETS, ANKLE PADS, ETC.).
GET CHECKUPS FROM DOCTORS REGULARLY FOR A BONE MINERAL DENSITY CHECK SO THEY CAN IDENTIFY IF YOU HAVE OSTEOPOROSIS. IF IDENTIFIED EARLY, FRACTURES AND BREAKS CAUSED BY THE DISEASE CAN BE PREVENTED.
ALSO, TO PREVENT BRITTLE AND BROKEN BONES IN THE FUTURE, BE SURE TO AVOID SOFT DRINKS WITH DARK COLORING LIKE DR. PEPPER, COKE, AND PEPSI. THE CHEMICALS IN THE COLORING WEAKENS BONES AND MAKES THEM EASILY BREAKABLE.
Eat nutrients that help build bone mass like calcium, vitamin A, vitamin C, vitamin D and protein
Keep your bones strong by doing weight-bearing exercises
Most of all, visit your doctor for regular check up
Organs Involved in the Skeletal System
Skeletal system problems can include cancers, breaks, poor nutrition, dislocation, disease and disorders.
The effects of these conditions can include pain, such as with a break, cancer or dislocation, or difficulty moving, such as with pelvis and hipbone disorders.
There are four types of bone diseases that can affect the skeletal system, which weakens bones, makes bones brittle, or causes a bacterial, viral or fungal infection in the bone.
Bone disorders that can affect the skeletal system in two different ways, one when the blood supply to the bone has ceased in some way and caused the bone to die and collapse, or the other causes bone deformity, uneven bone growth and brittle bones.
Poor nutrition is another source of problems for the skeletal system, as it causes inflammation and calcification, or mineral imbalance, of the joints. It can also increase the risk of osteoporosis later in life.
One of the more common diseases of the skeletal system is osteoporosis, a degenerative condition that causes your bones to become more porous than normal. Over time, the affected bones become brittle and weak, increasing your chances of fractures and breaks. And though these types of injuries aren't always a cause for alarm, someone dealing with osteoporosis can actually become disabled from severe impact to bones. Increasing your intake of calcium can go a long way to preventing this disease.
Another common disease of the skeletal system is arthritis. With this condition, joints in your body begin to suffer from inflammation, causing a great deal of stiffness and pain. Osteoarthritis is one of the most common forms of arthritis, but you can also suffer from a condition known as rheumatoid arthritis. As the condition persists, you may begin to experience mobility issues as well as problems with your posture or even motor skills. Treatment is usually based on reducing the symptoms of the condition, such as pain and stiffness, through a course of prescription medications, physical therapy or surgery (to correct or replace the affected joint).
Rickets is a childhood disease of the skeletal system characterized by soft bones. This is usually a result of a vitamin deficiency, namely vitamin D, which aids in the absorption of calcium, one of the main building blocks of your bones. It also helps your body absorb phosphorous, another crucial part of strong bones. Proper diet is really the best way to prevent this disease in children.
It is also possible to have cancer of the bones. Though the primary form of bone cancer isn't as common as cancer, there are cases of this type of disease, especially in children. It seems that abnormal cells are more apt to grow in bones that are growing than those that are already set in place. If you were to be diagnosed with bone cancer, treatment typically involves a standard course of care, including surgical procedures to remove the diseased tissue as well as radiation therapy, chemotherapy and sometimes hormone therapy.
Though not as common as other diseases of the bone, you may also develop a condition known as Paget's disease. This condition affects the way your bones metabolize. Throughout your life, your bones will break down, then quickly rebuild themselves. Normally, this is a reoccurring process of breakdown and renewal. But with this disease, your bone breaks down at a much faster rate than it can rebuild, causing it to become more fragile than normal.
Bursitis is the inflammation of the fluid-filled sacs that lubricate the joints of the body. Bursitis is most;y caused by overactivity of arm and leg joints.
Spina bifida is a birth defect of the spine in which the spinal cord does not form properly. As a result, the spinal bone and skin do not form leaving a hole in the lower back at birth.
Scoliosis is a sideways curvature occurring in the spinal column in adolescence. The reason that this disorder occurs more often in girls rather than boys is unknown.
Carpal Tunnel Syndrome
Carpel tunnel syndrome is a disorder that effects the median nerve in the wrist resulting in pain. It is caused by pressure and irritation of this nerve due to repetitive motion or injury.
