Skeletal System
The skeletal system provides definite shape and mechanical support to the body, and it also helps in movement and locomotion. Ask questions about the skeletal system and bones here.

What is a list of the functions of the skeletal system?
The skeletal system supports the body, protects internal organs, allows movement, stores minerals like calcium and phosphorus, and produces blood cells in the bone marrow.
What are the long term effects of exercise on your bones and joints?
Exercise has many effects on the bones and joints Some of the long term effects are: Regular exercise helps prevent cartilage degeneration in the joints, which will help to prevent arthritis. Regular exercise (especially before the age of 35) also helps delay any loss in bone density which occurs naturally as we get older, therefore bones are stronger and less likely to fracture. Strong bones also help to prevent the development of osteoporosis
What would we be if we didn't have any bones?
If we didn't have any bones, we would be like invertebrate animals such as jellyfish or worms, with soft bodies supported by other structures like cartilage or fluid-filled cavities. Our bodies would lack the structure and support provided by bones, making movement and protection of our internal organs more challenging.
The largest bone in you body is the femur.That bone is your knee
Can a Woman have 13 sets of ribs?
12. The same as men.
Women have the same number of ribs as men do, 24, or 12 on each side of the body.
You've been reading the bible haven't you? No, females don't have more rib bones than males because god took one of Adam's ribs to make eve.
Anyway, if you read the original, untranslated, bible you might realise that it might not have meant rib bone but 'male organ*' bone. Which explains the scar along the bottom of said organ.
*Can't say real word otherwise admin gets angry at me.
All agree that, based on medical research (somebody actually dissected cadavers and counted ribs, somebody actually looked at x-rays and counted ribs), men and women have the same number of ribs as each other. Twelve pairs of flexible, arch-like ribs form the lateral portions of the thoracic cage.
What will happen to our body if we don't have a skeletal system?
Without a skeletal system, our body would lack structure and support, resulting in the inability to stand or move. Our internal organs would also be left unprotected and vulnerable to damage. Overall, our body would not be able to function properly without a skeletal system.
What is demineralization of the bones?
Demineralization of the bones is when the bones have a lowered amount of minerals in the bone. Phosphate and Calcium is lowered in the bone and causes the person to have reduced bone strength.
What happens to your skeleton when you get older?
As you get older, the skeleton gradually begins to get smaller due to the reduction in disc thickness, although the bones do not decrease in length. That's why older people appear to be smaller than middle-aged people.
Because of factors such as muscle tone and either or both types of arthritis, the spine also begins to bend over slightly, so you get a bent back, but for some people, it's less obvious, for some it's a lot more obvious.
The biggest problem , especially in women, is that as hormone levels decrease bones become thinner and more brittle. The slightest trip, slip or fall can have dire consequences.
Actually, there is a tendency for the body to absorb calcium out of the bones. This happens in both men and women. In it's extreme, it is called Osteoporosis which is most common in women, but will occur in both men and women. The stooping over look that is a tell-tale sign of advanced osteoporosis is probably due to micro-fractures and compression of the vertebrae. At the same time there is also a thinning of the vertebral disks in the spine which accounts for much of the loss in height.
There are a number of things that can prevent osteoporosis. And, these should be begun early. Calcium supplements are commonly taken, and really since the peak bone mass is in the 20's, the calcium should be started early. Exercise may also help, and it is noted that some of the worst osteoporosis occurs in paraplegics that are prevented from doing exercise. Also, as noted above, there is some relation to hormones, and hormone deficiencies, especially in post-menopausal women. However, keep in mind that estrogen supplements are a double edged sword, and while they may benefit the bones, there may be increased cancer risk from taking them. Finally, there are some medications such as Fosamax which are not related to hormones, and will help with maintaining bone mass.
An interesting note is that while the bones may shrink or loose calcium with aging, cartilage can grow throughout a person's life which can cause the nose and ears to grow slightly.
it grows,and some bones grow into one
The ligament holds the radius to the ulna at the proximal end?
The ligament you are referring to is the annular ligament, which encircles the head of the radius and attaches it firmly to the ulna. This ligament allows for proper rotation of the radius around the ulna during forearm movements.
Is compact bone located in the diaphysis or in the epiphyses?
Compact bone is dense and solid in appearance and cancellous bone is characterized by open space partially filled with needle-like structures. Compact bone is found in the main shaft of long bones called the diaphysis. Its' function is to provide strong support without cumbersome weight.
What Are squamous stem cells that develop into osteoblasts?
Squamous stem cells are a type of stem cell found in bone marrow. They have the ability to differentiate into osteoblasts, which are cells responsible for bone formation. This process is essential for maintaining bone health and structure.
Why does a bird have compact bones?
In order for the bird to be as light as possible for flight. This "hollowness" reduces their body weight by about 5%, depending on what kind of bird it is, in contrast to their would-be weight if their bones were not hollow.
What happens to a chicken bone soaked in cola?
When a chicken bone is soaked in cola, the acidic nature of the cola can weaken the bone structure. Over time, the cola can dissolve some of the calcium and minerals in the bone, causing it to become softer and potentially break down.
Five toes on each of the rear feet, and four toes on each of the front feet.
The long bones of the body are developed by what type of ossification?
Long bones are developed by endochondral ossification, which requires a cartilage precursor.
How many bones in cervical spine?
Seven. The first vertebra being the Atlas and the second being the Axis.
What is the function of articular cartridge?
The Articular Capsule is a tought, flexible and fibrous capsule that covers the joint cavity. It is there to support and protect the joint.
Which metacarpal is proximal to the little finger?
The fifth metacarpal articulates proximally with the little finger. The fifth proximal phalanx meets the fifth metacarpal at the knuckle of the pinkie finger.
How many bones in a human vertebral column?
They are usually divided into 3 groups:
Cervical (7, Neck)
Thoracic (12, Chest)
Lumber (5, Abdomen)
They are then given numbers starting at the top (eg. C1 (Cervical 1), C2, C3, T1, L3 ect.)
Some have individual names like 'Atlas' or 'Axis' but this is uncommon.
What are legs that curve out called starting with ba?
Legs that curve out are called several things including bandiness or bandy-leg.
Probably the most common is bow-legs or bowed leggs
What is then difference between crab's skeleton and human's skeleton?
Crayfish have an exoskeleton, meaning that their support structure is found on the outside of their body. The skeleton is composed of one large body covering that is scleritized (hardened) in some places and left unslceritized (flexible) in others to allow for movement at joints. Humans have an endoskeleton, meaning that their support structure is found internally. The skeleton is made of hard bones that are held together at the joints by ligaments and muscles.
What links bones together at skeletal joints?
Ligaments connect bones at skeletal joints. They are strong bands of tissue that help stabilize the joint and limit its movement to prevent injury.
