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.

The Peripheral Nervous System is made up of 12 pairs of cranial nerves which transmit signals from the joints, skeletal muscles and skin to the brain. The PNS is further subdivided into the Somatic Nervous System and the Viscera.
What organ is located right above the left hip bone and can have sharp pains?
Spleen is along the left upper side of your stomach. Pancreas is also in that general area.
Which bone connects the arm bones to the axial skeleton?
Bones of the axial skeleton are typically joint by joints called synarthrosis, or amphiarthrosis. A synarthrosis provides very little movement if any. An example can be found in the skull; sutures are synarthrosis. An amphiarthrosis allows more movement, but are still rather fixes; the connection of the manubrium of the sternum and the body of the sternum is an amphiarthrosis.
As disk degeneration occurs in the spinal vertebrae, mechanical stresses result in osteophytic bars (osteophytes) which form along the ventral aspect of the spinal canal. These are sometimes called parrot beaks because of their shape.
What are the smallest human bones in the body?
The 3 ossicles are "little bones" found in the middle ear. They are the smallest bones in the human body, and each one has its own name:
- tympanic side = malleus or hammer
- middle = incus or anvil
- oval window side = stapes or stirrup
The smallest bone is Stirrup
Whats the quickest way to heal a bone?
Your own body will heal the bone in good time and if you have a good immune system it will heal quite quickly. Do as the doctor says and do the therapy requested by your doctor. Hope you're better soon.
What is mild medial joint space narrowing of the knee?
this refers to the disks in the spine ..as we age and other reasons the space begins to narrow between the vertabrae
The neck is part of the axial skeleton. The appendicular skeleton includes the bones of your arms and legs.
What is the substance that gives bones their strength and color?
Calcium
The mineralized osseous tissue, also called bone tissue, gives it rigidity and a honeycomb-like three-dimensional internal structure.
The majority of bone is made of the bone matrix. It has inorganic and organic parts. Bone is formed by the hardening of this matrix entrapping the cells.
The inorganic composition of bone (bone mineral) is formed from carbonated hydroxyapatite (Ca10(PO4)6(OH)2)
The organic part of matrix is mainly composed of Type I collagen.
How does one sign up for donating bone marrow?
You can join the Bone Marrow Registry to donate bone marrow online at the Bone Marrow National Registry. You must be between the ages of 18 and 44. Doctors choose registry members for donations 90% of the time, so it is a good idea to register so you can help someone in their time of need.
Does the calcaneous articulate with the distal end of the tibia?
The distal tibia articulates with the talus. The proximal tibia articulates with the femur.
What are the three bones that articulate with the femur?
The proximal end of the femur articulates with the acetabulum, which is the socket joint of the pelvis. The acetabulum is formed by the fusion of the three bones which make up the pelvis, the ischium, the ilium and the pubis.
The distal end of the femur articulates with the patellae (knee caps) and the tibia.
What system does the skeletal system work with to help move your body?
Cartilage, ligaments, and Muscles!
How does the respiratory system helps the skeletal system?
the bones protect the lungs that breath
not only that, the movement of the bones help the amount of air that can be taken in or let out
during inspiration (i.e; taking air in), the ribcage moves upwards and outwards (because of the contraction of external intercostal muscles and relaxation of internal intercostal muscles), this causes the sternum (chest bone) to move up and away from the ribcage. as a result, the 'dorsoventral' diameter of the thorax (lung cavity) increases. more air can now be taken in.
during expiration, the action is entirely opposite to this
Spiral fractures are described as crossing a bone at an oblique angle, creating a spiral pattern. This break usually occurs in the long bones of the body such as the upper arm bone (humerus) or the thigh bone
What would happen if your bones were weak?
Well, think of your muscles like your "businesses". Each muscle is a business you have been born with to make "money". So if a business grows weak, in muscles, a weak business can only get worse or get better. But once a muscle goes out of business, that's the end of it. The muscle fibers lost, can never be gained back...But! If you still have muscle, you can strengthen it like a struggling business, by working harder, working out, using them more than usual. If you leave them weak, they will over time, and quite quickly, shrink (atrophy), and the deterioration of muscles is very bad. You must keep what you have and make it stronger, because once it's gone, it's gone. :) Hope that helped.
Is the lungs in the front or the back of the ribs?
The lungs are inside your body so it isn't really in the front or back. It is in the chest area or upper body.
Does the rib cage protect the kidneys and the lungs?
Yes. The inferior edge of the liver can be palpated (felt) just inside the lowest portion of the rib cage.
Are babies bones softer than adults?
They don't have much hair on their skin. And they don't have many scars, dry spots, calluses, blisters, or other marks that would make their skin rough or bumpy. Many parents apply moisturizer to their babies' skin to help with diaper rash.
What systems does the skull belong to?
Cranium is apart of the skeletal system. it is the bone that protects the brain.
