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.

What three minerals make up bone?
The three main minerals that make up bone are calcium, phosphorus, and magnesium. These minerals are essential for bone strength and structure. Additionally, bone also contains smaller amounts of other minerals such as potassium and sodium.
What are the effect of hit bone during injection?
Hitting a bone during an injection can cause increased pain, bruising, and irritation at the injection site. It can also increase the risk of infection or damage to the bone itself. It is important to double-check the placement of the needle before injecting to avoid hitting a bone.
Can you talk if your jaw is broke?
If you were able to type that without falling on the ground in excruciating pain your jaw IS NOT BROKEN. A broken jaw hurts horribly, and you would know right away because you wouldn't be able to talk, move your mouth, or stop crying out for your mom in pain.
Which condition is known as bone marrow depression anemia?
In humans, the bone marrow - that virtual space within larger bones of the skeletal system - primarily serves as non-distensible, temperature, and hemodynamically-stable 'nursery' for the hematopoetic (RBC-red blood cells) and megakaryocytic(platelets) cell lines. While other fully-maturated cells of the monocytic, lymphocytic, and neutrophylic (immune system) - are often found there, too, they are typically observed as fully mature cells going about their purposeful migrations as they easily slip through membranes, exploring and ridding the body for foreign invaders, such as parasites, viruses, bacteria, fungi, and debris. However, the red cell and platelet types are found only as quite large progenitor stem cells more likened to the 'Gingerbread Mom' in the Nutcraker, hatching out little ones by lifting the hem of her skirt. Not many mature RBC or platelets are seen in the marrow because they tend to be released to the general circulation - the marrow won't function well if it is crowded or compacted- as RBC production is often held in a state of suspended animation, a slumber broken only by the whiff of erythropoetin, a hormone produced, stored, and released by the zona glomerulosa of the kidney(s) in response to a decreasing trend in the oxygen-carbon dioxide equilibrium.
Bone marrow depression is evaluated with a procedure that visually (stained microscopic slides) examines the contents and basically appears as an overall decrease in the numbers or functional appearance of the progenitor blast cells and can be as a result of anything that has a toxic effect on the biology of these unique cellular organelles (not organs but then they aren't exactly cells, either)
Ionizing radiation -intentional (prior to bone marrow transplant) or unintentional (Chernobyl) will negatively alter marrow cellularity as will many chemicals such as lead salts, chloramphenicol, and benzene-like solvents - the term aplastic anemia is used to describe a quite problematic result of such exposure when mature red blood cells numbers are so very low and new ones aren't being successfully produced and released to the circulation.
Which of these forms by intramembranous bone formation?
Flat bones such as the skull, clavicle, and sternum form by intramembranous bone formation, where bone is formed directly within a membrane without cartilage precursor. This process involves the differentiation of osteoblasts from mesenchymal stem cells and their subsequent mineralization to form bone.
What are the three different functions of the skeletal system?
1. Support 2. Protection 3. Movement 4. Mineral and growth factor storage 5. Blood cell formation- almost all blood cells are formed in red marrow. More than three, but I hope it is what you need!
What is carpal and radius bones connected to?
The carpal bones are connected to the radius bone through the radiocarpal joint, which is a synovial joint that allows for movement of the wrist. The radius bone articulates with the scaphoid and lunate carpal bones at the wrist.
When a bone breaks what carry the food into the bone?
Blood vessels supply the bone with nutrients and carry food and oxygen to the bone cells. When a bone breaks, blood vessels at the site of the fracture help in the healing process by delivering the necessary nutrients for bone repair.
What to organs do the ribs protect?
The organs protected by the rib cage include the heart, lungs, stomach, and liver.
When does bone remodeling take place?
Bone remodeling is a continuous process that occurs throughout a person's life. It is essential for maintaining bone strength and structure. The balance between bone formation and bone resorption is regulated by various factors, including hormones, physical activity, and dietary intake.
How did the hooded skull cap plant get its name?
The hooded skullcap plant gets its name from the shape of its flowers, which resemble hoods or caps, and the petals look like the shape of a skull. This unique appearance of the flower is what inspired its name.
What attaches the fingers to the hand?
The fingers are attached to the hand by tendons, which are tough bands of tissue that connect muscles to bones. These tendons enable the fingers to move and bend in response to muscle contraction.
How do you stop cramping in ribs?
To help alleviate cramping in the ribs, try taking slow, deep breaths and gently stretching the affected area. Applying a heating pad or taking a warm bath may also provide relief. If the cramping persists or is severe, it's best to consult a healthcare professional for further evaluation and treatment.
What is the incorrect alignment of bone ends called?
The incorrect alignment of bone ends is called a "malalignment." This can happen as a result of a bone fracture or dislocation, where the bone ends do not meet or align properly. Treatment may involve realignment through manual manipulation or surgery.
How can you break your knee cap falling of a bunk bed?
Falling off a bunk bed can result in a forceful impact on the knee when landing on the ground, causing the knee cap to break due to the sudden pressure and stress exerted on it. The height of the bunk bed increases the potential for injury, especially if the landing surface is hard or if the person lands directly on the knee. It is important to seek medical attention if you suspect a broken knee cap to ensure proper diagnosis and treatment.
Is this some kind of trick question?'Cause I think I'll ask my friends this to confuse them
I'm going to go for a wild guess...
it could be a cartilageneous joint (in your spine), synovial joint (freely movable joints), fiborous joint (immovable joints)...
Good luck on finding the answerrr ;)
Are the toes distal to the knee?
It is proximal as the knee is closer to the median / midline of the body than the foot. The foot is distal. Distal suggests a structure being further away from the median plane or the root of the limb than another structure in the limb. Proximal refers to a structure being closer to the median plane or root of the limb than another structure in the limb
What is the cure for bone marrow cancer?
Treatment for bone marrow cancer, also known as leukemia, typically includes chemotherapy, radiation therapy, targeted therapy, or stem cell transplant. The specific treatment plan will depend on the type of leukemia, the patient's health condition, and other factors. Close monitoring by a medical team is essential to determine the most effective course of action.
What is the fibrous connections between the bones of a fetal skull?
The fibrous connections between the bones of a fetal skull are known as fontanelles. These are soft spots that allow for flexibility during birth and rapid brain growth in infancy. They eventually close and solidify as the bones of the skull fuse together.
Which bone is not a facial bone?
There are multiple unpaired bones of the skull. The unpaired cranial bones are the frontal, occipital, sphenoid, and ethmoid bones. The unpaired facial bones are the vomer, mandible, and the hyoid.
