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.

Why you do sometimes get shivers down your spine when people walk past you or behind you?
because they startled you, you maybe you are found of them. sometimes it is just because you were cold;)
What is the sternum of a bird?
Birds have there forelimbs modified into wings to fly. The chest muscles has to be very much stronger in birds to enable them to fly. To bear the force of flying, the sternum in birds has be relatively large as compared to human being.
The name of the shoulder bone is called?
deltoids are the back shoulder muscles and trapezoids are the muscles around the shoulder/neck/back area
What is bone destroying cells are called?
None.
Are you thinking of ostioblasts? They destroy bone, but not cells.
What disorder is it when a bone is broken but the skin is not?
Its rare for a bone to go through the skin. There is no disorder that I know of
skeletal system
Scientific name for human upper leg bone?
The scientific name for the upper leg bone is the femur, I don't think it gets anymore scientific then that.
-jaz
What is the greater trochanter?
Lesser trochanter:
A pyramidal process projecting from the medial and proximal part of the shaft of the femur; it receives the insertion of the psoas major and iliopsoas muscles.
Greater trochanter:
A broad, flat process at the proximal and lateral part of the the femur; it receives the insertion of the gluteus medius and minimus, piriformis, obturator internus and externus, and gemelli muscles.
(Insertion - the place where a muscle is attached to the bone which it moves)
Does the humerous belong to the appendicular skeleton?
The humerus is the long bone of the upper arm. Since it is in an appendage, an arm or leg, it belongs to the appendicular skeleton
What is the function for osteoclasts?
Osteoblasts (from the Greek words for "bone" and "germ" or embryonic) are mononucleate cells that are responsible for bone formation; in essence, osteoblasts are specialized fibroblasts that in addition to fibroblastic products, express bone sialoprotein and osteocalcin.[1]
Osteoblasts produce a matrix of osteoid, which is composed mainly of Type I collagen. Osteoblasts are also responsible for mineralization of this matrix. Zinc, copper and sodium are some of the minerals required in this process. Bone is a dynamic tissue that is constantly being reshaped by osteoblasts, which are in charge of production of matrix and mineral, and osteoclasts, which break down the tissue. The number of osteoblasts tends to decrease with age, affecting the balance of formation and resorption in the bone tissue,[2] and potentially leading toosteoporosis.
Osteoblasts arise from osteoprogenitor cells located in the deeper layer of periosteum and the bone marrow. Osteoprogenitors are immature progenitor cells that express the master regulatory transcription factor Cbfa1/Runx2.
Osteoprogenitors are induced to differentiate under the influence of growth factors, in particular the bone morphogenetic proteins (BMPs).[3] Aside from BMPs, other growth factors including fibroblast growth factor (FGF),[3] platelet-derived growth factor (PDGF) and transforming growth factor beta (TGF-β) may promote the division of osteoprogenitors and potentially increase osteogenesis.
Once osteoprogenitors start to differentiate into osteoblasts, they begin to express a range of genetic markers including Osterix, Col1,[4] BSP, M-CSF, ALP,[5]osteocalcin,[4] osteopontin, and osteonectin. Although the term osteoblast implies an immature cell type, osteoblasts are in fact the mature bone cells entirely responsible for generating bone tissue in animals and humans.
What is the joint between the jaw and the skull?
the cranial fibrous, cartilaginous, and synovial joints.
immovable joints
What do osteoblasts osteocytes and osteoclasts have to do?
The three are all cells that can be found in the bone.
Osteoclast -Break down the bone.
Osteocyte- Carry nutrients and waste products to and from the blood vessels in the bone.
Osteoblast - Create new bone and repair damage.
What are the parts that make up the bone structure?
- Spongy Bone- open specs that provide support
- Compact Bone- rigid/dense bone made of connective tissue
Which is the larger bone in the face?
The mandible. Attached to the mandible (via tendons) is the masseter muscle, which is capable of generating more force (in terms of pounds per square inch) than any other muscle in the human body.
Is the heart distal to the rib cage?
The heart is SUPERIOR to the stomach...ABOVE... Distal usually only applies to the appendages, or limbs. The hand is distal to the elbow. The foot is distal to the ankle. Distal might give you partial credit for some answers but when you are dealing with the torso you will want to use SUPERIOR or INFERIOR.
What is the main term for fracture of the clavicle?
The main term for a fracture of the clavicle is a broken collarbone. It is one of the most common bones in the human body that get broken easily.
