Skeletal System

the proper name is the cranium

Muscle tissue. You have three types of muscles. Skeletal, smooth and cardiac muscles.

Fosamax is a prescription drug used to treat older people suffering from osteoporosis. The drug was designed to increase bone mass which subsequently reduces the risk of bone fractures. One reported side effect with Fosamax is jaw osteonecrosis. A few years ago, studies also indicated drugs like Fosamax for a long time may weaken bones.

it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage

the rib cage moves up and out when inhaling and moves down and in when exhaling.

Don't bother; you'll regret it later (tattoo removal is not enjoyable). But hey, you only live once; It depends on the business and the complexity of the design. The cheapest ones will be about £25 (40 USD). Add about £10 per hour of work. (15-17 USD) You could be looking at £40 to £120 ($70 to $200). A few words of advice: Make absolutely sure the equipment is sterile. Seriously- if you go in the day the guy forgets to check himself, it's as risky as unprotected sex with every customer who used the needle since it was last sterilised. (washing in water, however soapy doesn't count). Think about this very carefully. Think about how it'll look in 40 years, about why you want it and about what it will say about you. Sorry to keep lecturing you on this, but too many people I know have regretted getting tattoos done. Don't go for a cheap company- you may save some money now, but if they screw up, tattoo removal is expensive and very painful (trust me- it feels like holding your skin on a stove for 10 minutes). Think about this very, very carefully first. Tattoos lose their novelty after a few years.

There are two main catorgories of fractures. Complete and incomplete. A complete fracture is what we would usually refer to as a break (but that is not a medical term). An incomplete fracture is a hairline fracture, when the bone is cracked or patially broken. Another incomplete fracture is a greenstick, when the bone is broken on one side causing it to bend. Some coplete fractures are the simple fracture, where the bone is broken into two, straight across. Then the oblique fracture is very similar except it is broken on an angle. The spiral fracture is broken on an angle the twisted. Compound fracture is when the bone breaks through the skin. The comminuted fracture is a multi-fragmentary fracture.

The three ossicles (malleus, incus, stapes) act as a mechanical transformer, transmitting sound vibrations from the tympanic membrane to the inner ear's fluid-filled cochlea. This process helps amplify sound waves and maintain the sensitivity of the hearing system. The ossicles also provide a way to protect the inner ear from loud noises by limiting the transmission of excessive vibrations.

The medial malleolus is found on the tibia bone, which is the larger of the two lower leg bones. It is located on the inner side of the ankle and helps form the ankle joint with the talus bone of the foot.

Groth in long bones indicates a total lack of hormones.

The thoracic cage includes bony projections such as the ribs and the sternum which protect the thoracic organs including the heart and lungs. The ribs form a cage-like structure around the organs while the sternum provides additional protection and support. These bony projections help safeguard the vital organs in the chest cavity from external forces.

There are 7 in each foot and 8 carples in each wrist

Well, bone is not a conductor because it doesnt reflect or let electricity through
so bone is an insulator

The femur articulates with the coxal bone at the hip joint. This joint is a ball-and-socket joint, allowing for a wide range of movement in the hip. The femur head fits into the acetabulum of the coxal bone.

The knee joint is made up of the femur (thigh bone), tibia (shin bone), and patella (kneecap). It is also supported by ligaments, tendons, and cartilage that help stabilize and cushion the joint during movement.

No, bone marrow is not the outermost layer of the bone. The outermost layer of the bone is called the periosteum, which is a dense layer of connective tissue that provides support and protection for the bone. Bone marrow is found in the inner cavity of bones and is responsible for producing blood cells.

Weight-bearing bones include the femur (thigh bone), tibia and fibula (lower leg bones), and the bones of the foot such as the talus, calcaneus, and metatarsals. These bones support the body's weight during activities like standing, walking, and running.

A pronounced indentation in the lumbar region of your spine can be caused by conditions like lordosis (excessive inward curvature of the spine), spondylolisthesis (vertebrae slipping out of place), or muscle imbalance. It is important to see a healthcare provider for proper diagnosis and treatment.

Small channels that radiate through the matrix of bone are called canaliculi. These canaliculi contain cellular processes that allow for communication and nutrient exchange between bone cells (osteocytes) located within the bone.

Most fish have bones. Sharks and rays do not have bones but they do have bone-like structures that are made from cartilage.

I'm not sure, but isn't the skull on big bone? oh well i must be wrong.

----

No, the skull is not one big bone. The skull is made up of 22 bones, excluding the ossicles of the ear (small bones in the middle ear space which serve to transmit sound). There are 6 ossicles in total, three in each ear, and these bones are mobile. The only other skull bone that is able to move is the mandible (jaw bone). Thus, the seven bones that are able to move are:

- Mandible

- Left Malleus Ossicle

- Right Malleus Ossicle

- Left Incus Ossicle

- Right Incus Ossicle

- Left Stapes Ossicle

- Right Stapes Ossicle.

I hope this helps.

Loss of function in the bone marrow can lead to decreased production of red blood cells, white blood cells, and platelets. This can result in conditions such as anemia, increased susceptibility to infections, and impaired blood clotting. Treatment may involve blood transfusions or bone marrow transplant.

The sternum protects the heart and lungs by forming the front part of the rib cage. It also provides attachment points for various muscles involved in breathing and upper body movement. Additionally, the sternum assists in stabilizing the rib cage during activities like breathing and physical exertion.

Bone is harder and more rigid than cartilage due to its mineralized matrix, predominantly composed of calcium and phosphorus. Bone also contains specialized cells like osteocytes, which are responsible for maintaining bone structure and function. Cartilage, on the other hand, is more flexible and resilient due to its high water content and lacks the mineralized matrix found in bone.

The osteon is the structural unit of compact bone. Haversian system is a microscopic, structural unit of compact bone also called the osteon. The osteons are arranged in multiple layers or rings called concentric lamella.
