Are the bones all connected?

Fish bones are also bones, if you have seen fish bone specimens, you will find that in fact, the bones of fish are all connected, but because of my cooking and eating methods, the bones are separated, so we can't see the connection between the bones, if you dissolve the muscle tissue of the fish with a solvent, you can see that the bones are all connected together by a regular pattern.

Are there any bones that aren't connected? Yes, there is. Several bones of cetaceans are in the free cranial cavity, and the specific one is forgotten, which is a characteristic of the identification of cetaceans.

The bones and joints are connected by joint capsules.

Joints are made up of joint capsules, articular surfaces, and articular cavities. The joint capsule is surrounded by the outside of the joint, the smooth bone in the joint is called the articular surface, and the cavity part in the joint is the joint cavity. Normally, there is a small amount of fluid in the joint cavity to reduce friction during joint movement.

When the joint is diseased, it can increase the fluid in the joint cavity, resulting in joint effusion and swelling. Some people are born with a loose joint capsule, and the range of motion of the joint can be great.

ls。。。The function of fish bones is to promote the swimming of fish, and not all fish have spines.

The loose bones of the fish should play the role of supporting the muscles.

In fact, people also have similar free bones, such as patella, phalanges, etc. It's just a role to be combined.

The fish are also connected....It fell off when I ate it.

The connective tissue at both ends of the muscle, called the tendon. Each piece of skeletal muscle is divided into two parts: the muscle abdomen is composed of muscle fibers, the color is red and soft, and the tendon is composed of dense connective tissue, the color is white and hard, and there is no contractile ability. The tendons of the longus muscle are mostly cord-shaped, and the tendons of the latissimus muscle are broad and thin, membranous, also called aponeurosis.

Tendon blood vascularity**.

Tendon muscle: There are more blood vessels entering the tendon in the ventral transition portion;

A few branches of the tendon and the blood vessels adjacent to the bone or periosteum enter the tendon;

In unsheathed sites, blood is derived from peritendinous tissues;

In areas where synovial fluid is encased, the blood vessels of the tendon are distributed to the tendon through the mesotendinae.

The connection between bones is called bone connection, and there are three forms of bone connection: non-active connection, such as the connection between the skull, semi-active connection, such as the connection between the vertebral bodies in front of the vertebral body, movable connection, and in general, joints, such as the shoulder and elbow joints of the upper limbs, hip joints and knee joints of the lower limbs, etc., joints are the main form of bone connections.

Because the evolutionary reason of the skeleton is secondly related to the supporting function of the skeleton, all the bones he as our support system is the structure of the organism is more in line with the mechanical principle, as for the importance of support, we can cite the following items There is no hard support system, it is difficult to increase the volume of soft tissues and soft tissues of multicellular organisms, and the support system enables the vital organs in the body to be rationally configured in space.

And to maintain a relatively stable spatial position, to achieve the harmony of the overall function, the support system is the development of the locomotor organs of the animal and eventually to remove the animal from the water environment, the development of the support system in the plant allows the plant to expand the surface area and obtain a high degree of space, and finally, the plant can develop to the land. Eating foods rich in collagen and elastin is most beneficial for bone health, such as milk, eggs, walnuts, meat skin, fish skin, pig's trotter jelly, etc.

Normal people do not need to take additional health supplements, such as protein powder. Excessive protein intake is harmful to bones, will increase the acidity of human blood, accelerate the dissolution of calcium in bones and the excretion of calcium in urine, followed by bones are bones, these two concepts are equivalent, joints are equivalent to bone connections in a broad sense, but our bone connections are not limited to joints in a narrow sense, in a broad sense, joints include fixed joints and movable joints, which are equivalent to the direct and indirect connections of bone connections.

If you have other different ideas and views, you can share your personal views in the comment area below, if you like me, you can pay attention to it, and finally wish you all the best.

In the human body, the only one that does not link the two bones together is the head and neck, which is connected by muscles, nerves, and blood vessels.

It's the head and neck, and it's the fibrous nerves between the muscles that connect the head and neck. There are three forms of bone junctions: inactive junctions, semi-active junctions, and movable junctions.

In the human body, the only muscle that does not connect the two bones together is the head and neck, which is connected by the muscles and the fibrous nerves between them.
