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.

Are bones made up of minerals?
Bones are made out of calcium, they are also in charge of making the cells that you have in your body through its bone marrow.
What is an external skeleton and an internal skeleton?
All animals, including humans have skeletons. Humans have an internal skeleton. This means that our bones is on the inside of us. When an animal has an external skeleton it means that their skeleton is on the outside. These animals who have an external skeleton have what we commonly call shells. These shells are their skeleton which keeps their insides together. If you think of one of those big crabs and how there is a shell on the outside of them (not sea shells) this is their skeleton which is an external skeleton.
The tag 'C' means the 'cervical' section of the spine, which is the first section at the top of the spine ... the first group of vertebrae right under the skull. There are seven cervical vertebrae, (unless you've had C4 thru C7 fused, like me), and then the thoracic section starts. 'C3' means the third vertebra down from the skull. That pointy bone sticking out at the bottom of your neck/top of your back is 'T1'. All the vertebrae above that are in the cervical section.
Why is your hand and lower arm swollen days after surgery?
that is normal reaction of the body due to internal work and interuption
it travels through your bones by bone marrow, a jellylike substance, where new blood cells are constantly being produced
How does your jaw bone stay held up?
The jawbone, or mandible, is held in place by a combination of ligaments, muscles, and the temporomandibular joint (TMJ). The TMJ connects the jawbone to the skull, allowing for movement while providing stability. Ligaments and muscles surrounding the jaw offer support and control its movement during activities like chewing and speaking. Additionally, the alignment of teeth helps maintain the jaw's position.
What is lamella in the human bone?
Lamellae are the layers that form concentric rings within the Haversian systems that make up bone tissue.
calcium obviously. apart from calcium it is necessary to lift weights to make then hard.
Floating ribs are four atypical ribs (two lowermost pairs, XI-XII) in the human ribcage. They are called so because they are attached to the vertebrae only, and not to the sternum or cartilage coming off of the sternum. Some people are missing one of the two pairs. Others have a third pair. Most, however, possess only two pairs. Their position can be permanently altered by a form of body modification called tightlacing, which uses a corset to compress and move the ribs.
What type of bones form the arms and legs?
the big arm bone on the top is called the humerous.
the forearm bones are ulna and radius.
the big leg bone on top is called femer
the bottom leg bones are tibia and fibula
Why is calcium and phosphorus good in your diet?
They are essential micro-nutrients firstly because they fulfill various functions in the human body. Calcium is most abundant in the bones thus eating Calcium rich foods like cheese might help to keep bones strong and prevent their degeneration. Phosphorus is the building backbone of energy, genetic material and every cell itself. Lack of phosphorus might cause problems starting with bone and muscle degeneration up to blood cell disruption. Phosphorus intake might harden bones too.
Food rich in Calcium is hard cheese and rich in phosphorus are dates.
The cranium is a set of bones that surrounds what?
The cranium is a set of bones which surround the brain. The cranium is sometimes referred to as the skull in humans.
What anemia is characterized by bone marrow that produces large abnormal red blood cells?

Authors: Ann Ehrlich and Carol L. Schroeder
Do plants have skeletal system and circulatory system?
Yes. Trees for instance draw water up from the ground using concentration gradients through their phloem, found in the middle part of the tree. Then sugars generated in the leaves are transported down the outside or inner bark part of the to the roots down the concentration gradient.
Cartilage is flexible connective tissue that is often found in joints near bones. Elastic cartilage is more flexible than hyaline cartilage. It is found between bones in joints to stop them from rubbing of bone tissue and to allow movement without pain. It is white and is shiny and hard. Also it is 10x slipperier than ice.
What is a smooth round opening in the bones?
A foraman which is what allows nerves and blood vessels to enter bones.
Which vertebra articulates with the occipital bone?
The first cervical vertebra, called C1 or the atlas, articulates with the occipital bone.
Why is the backbone made up of small bones?
If the spine was one continuous bone, we would be very restricted in our upper body movements. The jointed vertebrae allow flexibility.
There are several bones in the Ankle. However, the one most commonly referred to as the "Ankle Bone" (the knob-like bone that protrudes out from where the ankle rotates) is called the Medial Malleolus.
