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.

yes babies bones have hardly any joint that's why they have more
A break in a bone is known as a fracture. Fractures can be caused by trauma, such as a fall or a direct blow to the bone. Treatment for fractures may include immobilization with a cast, splint, or surgery, depending on the severity of the break. It is important to follow medical advice for proper healing to avoid long-term complications.
Why is the stirrup bone the anvil bone and the hammer bone have those names?
The stirrup, anvil, and hammer bones in the ear are named based on their shape and function. The stapes (stirrup) bone is the smallest and resembles a stirrup used in horseback riding. The incus (anvil) bone has a shape similar to an anvil used by blacksmiths. The malleus (hammer) bone looks like a hammer used for striking.
Beneath the outer membrane of bone there is a layer of?
compact bone tissue, which is dense and solid, providing strength and protection to the bone. Beneath the compact bone tissue lies the spongy or trabecular bone tissue, which is less dense and consists of a network of interconnected trabeculae that give support and flexibility to bones.
What system controls how your muscles move your bones?
The nervous system controls how muscles move bones. When a muscle receives a signal from the brain, it contracts, pulling on the bone to create movement. Coordination and fine-tuning of movements are controlled by the cerebellum in the brain.
We have skeletons so that we don't look like a big glob.
What is the human skeleton made of?
The human skeleton is primarily made of bone tissue. Bones are composed of collagen, a protein that provides flexibility and strength, and mineral deposits such as calcium and phosphorus that make them hard and rigid. The skeletal system plays a crucial role in providing support, protection for vital organs, and facilitating movement.
Ligaments are tough bands of tissue that connect bone to bone in the body, providing stability to joints and limiting excessive movements. They help to reinforce the joint and prevent excessive motion that could lead to injury.
Osteoid is the organic component of bone tissue, primarily composed of collagen. Hydroxyapatite is a mineral component of bone tissue, providing strength and hardness to the bone. Osteoid contributes to the flexibility of bones, while hydroxyapatite enhances their structural integrity. Together, they give bones their rigidity and resistance to fractures.
Which two bones are in the forearm?
The ulna and the radius are the two bones in the forearm.
Latin: Ulnaris et. radialis.
If you hold your arm at your side with the palm forward ulna is palpable on the medial (inside) part of the forearm, whilst the radius is palpable on lateral (outside) side.
In layman terms, the radius is on the side of your thumb, and the ulna on the side of the pinky-finger.
What is bad for the skeletal system?
Factors that can be bad for the skeletal system include poor nutrition, lack of physical activity, smoking, excessive alcohol consumption, and certain medications that can weaken bones. Additionally, conditions such as osteoporosis and arthritis can also negatively impact the skeletal system.
The stiff rib cage surrounding the thoracic cavity provides protection for vital organs such as the heart and lungs, helping to prevent injuries to these structures. In contrast, the softer muscular wall surrounding the abdominal cavity allows for more flexibility and movement, which is necessary for functions such as digestion and childbirth.
The patella, also known as the kneecap, is located on the front of the knee joint. It articulates with the femur (thigh bone) and protects the knee joint during movement.
What area of head and skull have greatest concentration of vessels?
The blood vessels to the brain are primarily in the Meninges, consisting of several layers with the Pia layer being primarily capillaries, and the arachnoid space being full of smaller vessels.
Here are some good reference articles.

Is blood-forming marrow in the diaphysis of most long bones of an adult?
No, blood-forming marrow is typically found in the red marrow located in the spongy bone at the ends of long bones (epiphysis) and in flat bones such as the sternum, ribs, pelvis, and skull. The diaphysis of long bones primarily contains yellow marrow, which consists mostly of fat cells.
How much does a human pelvic bone weigh?
An adult human pelvic bone weighs approximately 2.5 pounds (1.1 kilograms). The weight may vary slightly between individuals due to factors such as age, sex, and overall bone density.
Bones are made of a network of calcium laid down by cells. As kids grow, special cells at the end of bones add new calcium to the network of the bone. Children have layers of these cells in the shape of plates at the ends of their bones. These are called growth plates, and they close up when kids reach their full adult height. The growth plates are open when you are born and the more and more that you grow, the more closed they become and eventually close for good when you are fully grown, which is usually around the age of 16 for the average child.
Yes, that's true and also this is right too ---> The skeleton of a fetus growing inside its mother's body does not contain hard bones. Instead, most bones start out as flexible cartilage. When a baby is born. it still has a lot of cartilage. As the baby grows, most of the cartilage is replaced by a bone.
The ones of a child continue to grow. The long bones lengthen at their ends, in areas called growth plates. The growth plates are areas of cartilage that continue to make new cells. Bone cells called osteocytes move into the cartilage, hardening it and changing it into bone. Growth continues into adolescence and sometimes even into early adulthood. Most bones harden completely after they have stopped growing. Even after bones have stopped growing, they can still repair themselves if they break.
When cremated will a persons bones burn to ash?
Yes, there may be some whole teeth left in the ashes. no not usually because they are usually burned to much the way they are burned so there might be some big chuncks of ash but not probly teeth
What minerals are essential for healthy bones?
Calcium, phosphorus, and magnesium are essential minerals for maintaining healthy bones. Calcium is the main mineral present in bones, while phosphorus helps form the structure of bones and teeth. Magnesium is also important for bone health as it helps regulate calcium levels in the body.
It's possible that you are experiencing gallbladder inflammation or gallstones. Eating fried foods can trigger a gallbladder attack in some individuals. The symptoms you described, such as severe abdominal pain that radiates to the ribs, tenderness, and rigidity, are common with gallbladder issues. It's important to seek medical attention for proper diagnosis and treatment.
What are the functions of cartilage?
The function of hyaline cartilage is to provide flexible support. It has great tensile strength (due to the collagen) and is highly resistant to pressure (due to the ground substance). Hyaline cartilage provides a framework for the developing embryo prior to the appearance of bone. Later, it supplies the mechanism by which bones grow in length.
The bone between the sternum and the scapula?
Sychondrosis (a type of hyaline cartillage) is the joint between the first rib and the sternum, otherwise referred to as the first sternocostal joint. this joint type is also found in the epiphyseal plates of long bones prior to fusion.
This is kind of a short answer so you can memorize it.
Tendons Tie muscle to bone. Ligaments Link bone to bone.
Tendons = Tie
Ligaments = Link
That's pretty much it.
