Skeletal System

articulation

the bone that protects the brain is the skull.

contractions like muscle

You must be at least 18 years of age and no older than 60. An individual must be 18 to donate because marrow donation is a surgical procedure and the person undergoing the procedure must legally be able to give informed consent. A guardian or parent cannot sign a release or give consent because unrelated marrow donation is a voluntary procedure and is not beneficial or life-saving to the donor.

This mineral is hydroxyapatite.

The backbone is a column usually consisting of 24 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs.

it is the skull that affords most complete protection of the body it protects the brain or some how i not sure maybe the ribs and spinal cord is the one who affords but in my study the ribs protects the lungs and the spinal cord is connected to the nervous stem BUT I'AM NOT SURE SORRY

Tendons connect muscles to bones. It is important not to confuse tendons with ligaments which connect two bones together.

Another name for the tigh bone is called the femur

In your body, the most bones you have are located on your feet!

Hope that helps you !

The humerus.

The muscular system requires significant attention to work at optimum conditions. Regular activity coupled with adequate sleep and a healthy balanced diet should keep all systems in great operating order.

a fish bone is more brittle

I THINK!!!!!!!

The more commonly known kneecap sits on the top (anterior) side of our tibia (shinbone), the largest and weight-bearing bone of the lower leg.

the "hip bones", or illium of pelvis, are connected to the pelvis.

A joint is a place where bones meet, and often articulate or move. The bones that connect at those joints could be fractured at the joint, so you'd have for example, a fractured ankle.

The connecting tissues within joints could be torn or separated, but these aren't bones.

The rib cage is made of bone with intercostal muscles allowing them to expand and contract when breathing.

It is called manipulation and done under a general anaesthetic. If unsuccessful, open reduction and fixation is carried out with plate and screws depending upon the fracture site

The red blood cells are produced in the red bone marrow in the center of the bone.
Marrow.
Red blood cells, or erythrocytes, are made in the bone marrow as are white blood cells or leukocytes and they originate from stem cells. The marrow is located in the length of the long bones until we get older, then it will diminish with age. As we age the marrow is predominantly in the sternum or breastbone, the iliac crest or the hip bone of the pelvis, and in the vertebrae of the spine. The ends of the long bones or epiphysises are solid bone covered with cartilage for the strength needed for the movable joints.

because they are to hard for our stomach to digest.

The most obvious signs are extreme and immediate pain in your back, numbness or the feeling of portions of your body being "asleep" and often the inability to move.

Not really. The nails are more of a compact layered skin structure. Cartilage is more for cushioning and lubrication between bones. Some areas do have a rigid structure of cartilage, but it's softer than nail tissue.

hystoid

The lambdoid suture articulates with the parietal and occipital bone of the skull. Joint is another name for suture when talking about 2 bones connecting in skull.
