Skeletal System

Fish with a skeleton made of bone are classified as bony fish, or Osteichthyes. This group includes a wide variety of species, such as salmon, trout, and goldfish. Bony fish possess a skeleton primarily composed of calcified bone, contrasting with cartilaginous fish like sharks and rays, which have skeletons made of cartilage. Bony fish are the most diverse group of vertebrates, making up a significant portion of all fish species.

The bottom of the brain sits on the Occipital bone.

I need to have a hip replacement and found out from an MRI that part of the bone died. I also have ostioarthritis in it. What makes a bone die?

Blood production

Bone marrow is the flexible tissue found in the interior of bones. In humans, marrow in large bones produces new blood cells. It constitutes 4% of the total body weight of humans. The new blood cells are released into the body and go through the arteries and veins to the heart to get oxygenated from the air we breathe in, that's why blood is red because it has been oxygenated but when it hasn't it is blue.

Movement

The joints between bones allow movement, some allowing a wider amount of movement than others, e.g. the ball and socket joint allows a greater amount of movement than the pivot joint at the neck. Movement is powered by skeletal muscles, which are attached to the skeleton at various parts on bones. Muscles, bones, and joints provide the basic needs for movement, all coordinated by the nervous system.

Support

The skeleton provides the framework which supports the body and maintains its shape. The pelvis and associated ligaments and muscles provide a floor for the pelvic structures. Without the ribs, coastal cartilages, and the intercostal muscles the heart would collapse.

the skeleton also provides shape and protection to vital organs....

The humerus bone is the one in your upper arm, and it is needed when you want to move your arm.

You only have one ankle on each foot, but there are different bones that make up your ankle.

cartilage is replaced

Cortical bone, also known as compact bone, serves several vital functions in the skeletal system. It provides structural support and strength to bones, enabling them to withstand mechanical stress. Additionally, cortical bone plays a role in protecting the inner, more fragile trabecular (spongy) bone and housing bone marrow. Its dense composition also aids in the storage of minerals, particularly calcium and phosphorus, which are essential for various physiological processes.

=i think they help you by pretecting your body and i think they pretect the bones and muscles...=i think joints help you by pretecting your body and keeping your muscles and bones safe. BY HANEEYAH Y4

The 33 ring-shaped bones of the spine are called the vertebrae.

I'm sure its the Skeletal System because the bones protect,store, and supports minerals

No, a tendon attaches a muscle to bone. A ligament attaches a bone to another bone.

This is similar to the structure of a condom. It is extremely lubed up and has a whole for insertion. After the long rigid part there is the end where a bubble of air is stalled, this is what helps you when you need to heal a bone.

Appendages and lower extremities.

Yes they do.

protecting your friggen organs! whatcha think?

The skeleto-muscular system is the set of organs including the bones, the skeletal muscles, and the associated tendons and ligaments. The cat's skeleton (the bones) are part of the skeleto-muscular system.

Stapedectomy is a surgical procedure in which the innermost bone (stapes) of the three bones.of the middle ear is removed, and replaced with a small plastic tube of stainless-steel wire (a prosthesis) to improve the movement of sound to the inner ear.

So it cushions the bones and so the wont grind when they hit each other. also for a kind of suspension for when you jump.

the AXIAL skeleton, which makes up the bones of the thorax, spinal column, and skull. and the APPENDICULAR skeleton, which includes the bones of the arms, legs, shoulder girdles, and pelvis.

The matrix for bone is laid down in thin layers called lamellae. The lamellae are arranged in concentric patterns around tubes called osteonic canals. Between the layers of lamellae the osteocytes are placed in depressions called lacunae. This pattern of concentric circles forms a cylinder-shaped unit called the osteon.
