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.

Different types of wood joints?
Wood joints are essential for connecting pieces of wood in construction and furniture making. Common types include butt joints, where two pieces are simply butted together; dovetail joints, known for their interlocking shape providing strength; and mortise and tenon joints, which involve a cavity (mortise) and a protruding piece (tenon) that fit together securely. Each joint type serves different purposes, balancing aesthetics, strength, and ease of assembly.
What is the answer when to bones meet?
When bones meet, they form a joint. Joints allow for movement and provide stability to the skeletal system. Depending on the type of joint—such as hinge, ball-and-socket, or pivot—bones can move in various ways, enabling activities like walking, bending, and rotating. Proper joint function is essential for overall mobility and health.
What kind of skeletal system does a sponge have?
Sponges have a water based circulatory system, a combination of the natural flow of water around and through them, plus a kind of hydrodynamic suction, where a slightly faster flow of water at their top portions sucks water through from the bottom, plus the collective wriggling action of flagellated cells on the surface of their bodies which creates a water current through the pores of the sponge.
Gases dissolved in the water enter and leave the sponge cells by diffusion.

Why is Synovial Effusion happened for a 19 months baby girl in the left knee?
To remove excess fluid on the joint.
What joint is superior to the knee?
In anatomy "superior" means above, as in if someone is standing up the hip is above the knee. The hip joint is the first joint higher than the knee, so it is the first joint "superior" to the knee.
Ants don't have bones. Like other insects, they are arthropods and have an exoskeleton (hard covering outside their body) instead.
What differences between compact and spongy bone can be seen with the naked eye?
As the names suggest, compact bone is solid-looking, and forms the outer layers of all bone (and the shafts in long bones). Spongy bone looks like sponge, with small holes, and is found on the inside of bones and the expanded heads of long bones.
As the names suggest, spongy bone is softer than the solid, compact bone. With the naked eye, you can see that the compact bone is smooth and located around the outside of a cross-section of bone. Spongy bone, on the other hand, is located on the inside and is very porous, like a sponge.
Where are your tenth and 11th ribs located?
The tenth and eleventh ribs are located in the lower part of the ribcage, specifically in the thoracic region of the spine. The tenth rib is typically attached to the tenth thoracic vertebra and is one of the true ribs, connecting directly to the sternum via cartilage. In contrast, the eleventh rib is considered a floating rib as it does not attach to the sternum or have a cartilage connection. These ribs help protect the organs in the lower thorax and upper abdomen.
What is a crest or projection on the superior surface of the ethmoid bone?
perpendicular plate
The crista galli.
What part of the embryo develops into spine?
Down the back is a structure called the Notochord. The structure is cartilaginous and over time turns in to bone. You still have some of this cartilage when your a child, but as you grow up it is all replaced with bone.
Either side of the Notochord are somite that can migrate to make other tissues too.
Will you become high if you grind your arm down to the bone then crush and snort the bone powder?
um no if you do that you are completely crazy and or a zombie/ cannibal
What is the hollow spaces contaning a soft substens?
The hollow spaces containing a soft substance are typically referred to as cavities or chambers. In biological contexts, these can include structures like the ventricles of the heart or the sinuses in the skull, which often contain soft tissues or fluids. In geological terms, hollow spaces in rocks or minerals may hold softer materials like clay or other sediments. These cavities play important roles in the function and structure of the systems they are part of.
