HUMAN BODY JOINTS AND MARROW

For the word of God is quick, and powerful, and sharper than any two edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. (Hebrew 4:12)

From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.(Ephesians.4:16)

I am poured out like water, and all my bones are out of joint: my heart is like wax; it is melted in the midst of my bowels.(Psalms 22:14) 

A joint or articulation (or articulate surface) is the location at which bones connect.They are constructed to allow movement (except for skull, sacral, sternal, and pelvic bones) and provide mechanical support, and are classified structurally and functionally

Joints are mainly classified structurally and functionally. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. In practice, there is significant overlap between the two types of classifications.

and they are not connected to Christ, the head of the body. For he holds the whole body together with its joints and ligaments, and it grows as God nourishes it.(Colossians 2:19)

And having pulled away the skin of the victim, they shall cut up the joints into pieces,(Leviticus 1:6)

WHAT PURPOSE DO JOINTS SERVE?

Joints provide flexible connections between your bones. Imagine if you didn't have knee joints or hip joints. You'd walk around stiff-legged and you wouldn't be able to cross your legs or even squat on the toilet. Going up the stairs and even driving a car would be impossible.

Your body has different kinds of joints. Some, such as those in your knees, work like door hinges that help you to move back and forth. The joints in your neck help your bones to pivot so that you can turn your head. And other joints such as in the shoulder enable you to rotate your arms 360 degrees much like a shower head.

WHAT ELSE DO BONES DO?

Bones are made of "biochemical stuff" that give them strength. This "biochemical stuff" helps them grow and repair themselves. Just like other cells in your body, the bone cells rely on blood to keep them alive because the blood brings the bones food and oxygen and then removes the waste.

Bones are alive because they are made of living cells. When there is a break in tissue or bone, your bone cells are busy growing and multiplying to repair the break! When you break your arm, blood clots form to close up the space between the broken segments, then your body will call in the troops (bone cells) to deposit more of the hard stuff to create a bridge in the break. The bridge joins both sides and heals the break.

WHAT IS BONE MARROW?

Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in theheads of long bones in a process known as hematopoiesis. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb). The hematopoietic component of bone marrow produces approximately 500 billion blood cells per day, which use the bone marrow vasculature as a conduit to the body's systemic circulation.Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system.

Bone marrow transplants can be conducted to treat severe diseases of the bone marrow, including certain forms of cancer. Additionally, bone marrow stem cells have been successfully transformed into functional neural cells,and can also potentially be used to treat illnesses such as inflammatory bowel disease.

Many bones are hollow and this makes them light, although strong. The center of many bones is where bone marrow creates new red and white blood cells. Red blood cells distribute oxygen to all parts of your body and white blood cells assist you in fighting disease, critters and germs.

WHAT IS LIGAMENTS:

In anatomy, a ligament is the fibrous tissue that connects bones to other bones and is also known as articular ligament, articular larua, fibrous ligament, or true ligament.
