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 bone runs along the thumb side of the forearm?
The bone that runs along the thumb side of the forearm is called the radius. It is one of the two bones in the forearm, the other being the ulna. The radius is located on the same side as the thumb when the palm faces up.
What are the purpose of the skeletal system?
first off skeletal not skeleton system
but the six main functions are
1. support - provides structural support for the entire body
2. protection - surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain
3. movement - skeletal muscle is attached to bone so it pulls on the bone when it contracts
4. mineral homeostasis - stores calcium and phosphorus--minerals are released into the blood when needed
5. blood cell production - red bone marrow produces red blood cells, white blood cells and other blood elements
6. storage - storage of minerals and lipids (fats) - yellow marrow stores fat -(found in long bones)
What are the functions of flat bones?
The function of many flat bones is to form a protective wall round abody cavity and so they are often curved.
What part of the rib articulates with the body of the vertebra?
head
The pedicle of the rib articulates with the transverse process of the thoracic vertebra.
Hardened or thickened part of the skin, especially on the palm of the hand or sole of the foot, as from continual friction or pressure. Also called calosity.
A callus (or callosity) is a toughened area of skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form.
Is the brain deep to the skull?
Yes, but that term is not usually used. The brain is encased or surrounds most of skull and is said to be inferior to the skull. Another term or two that can be used are underneath or beneath.
What body system is the pelvis in?
It is located at the base of the spine (properly known as the caudal end). The pelvis incorporates the socket portion of the hip joint for each leg (in bipeds) or hind leg (in quadrupeds). It forms the lower limb (or hind-limb) girdle of the skeleton.
How do you make a bones be gone potion?
There is no known scientific method to make a "bones be gone" potion. Bones are essential for the structure and support of the body, and removing them would be harmful and fatal. It is important to focus on maintaining bone health through a balanced diet, exercise, and medical advice if necessary.
What would cause an adult to have woven or unorganized bone?
In adults woven bone is created after fractures or in Paget's disease. Woven bone is weaker, with a smaller number of randomly oriented collagen fibers, but forms quickly; it is for this appearance of the fibrous matrix that the bone is termed woven. It is soon replaced by lamellar bone, which is highly organized in concentric sheets with a much lower proportion of osteocytes to surrounding tissue.
After a fracture, woven bone forms initially and is gradually replaced by lamellar bone during a process known as "bony substitution."
What one bone is superior to the temporal bone?
The sphenoid bone is superior to the temporal bone in the skull.
What are the two bones that are anterior to the occipital?
The two (left and right) parietal and the temporal bones are anterior (closer to the front of the body).
What are four bones that are distal to the femur?
There are only two that are actually distal: the tibia and the fibula.
What are the ranges of motion of the lumbar spine?
The full possible Range Of Motion in the spine from fully extended to fully flexed is 250o (140o extension and 110o flexion) - however the only way to get full 140o extension is flip over backwards so your stomach is facing upwards and your hands and feet are both on the floor (make sense?), however the lumber spine only accounts for 95o of this motion (35o extension and 60o extension). The full possible lateral ROM the spine is 75o each way, however the lumber spine only accounts 20o of this.
What bone marrow is produced in the spongy bone of the skeletal system?
The red bone marrow is important in the skeletal function of producing blood.
What is the name of the structure made of bone and cartilage separating the nostrils?
The structure separating the nostrils is called the nasal septum. It is composed of bone and cartilage and helps to divide the two nasal passages.
How the patella and scapula similar in form and function?
The patella and scapula are similar in form as they are both flat and triangular bones. In terms of function, both bones provide attachment points for muscles that aid in movement: the patella assists in knee extension by increasing the leverage of the quadriceps muscles, while the scapula provides attachment for muscles that move the shoulder joint and stabilize the upper arm.
"Distal" refers to a position farther away from the point of attachment or origin. In the context of the knee, distal would refer to structures located further away from the body, such as the lower leg or foot.
What connects the bones in movable joints?
Ligaments are fibrous bands of tissue that connect bones in movable joints. They provide stability and allow for smooth movement of the joint.
What is the cartilage articulates with another bone or bone process called?
The cartilage that articulates with another bone or bone process is called articular cartilage. It covers the ends of bones within joints and helps to reduce friction and absorb shock during movement.
