Skeletal System

The bone in our head is called the skull. It protects the brain and provides structure for the face.

The upper part of the rib cage contains only lungs.

Yes, sleep plays an important role in the healing process of broken bones. During deep sleep, the body releases growth hormones that promote tissue repair. Additionally, adequate rest allows the body to conserve energy for the healing process.

The joint cavity helps to reduce friction between bones during movement by secreting synovial fluid. It also provides a space for nourishment and removal of waste products from the joint. Additionally, the cavity allows for smooth and pain-free movement of the joint.

Flexibility is the reason we have a chain of small bones instead of a big one down our back. Imagine a fish trying to swim without a flexible spine. It would be difficult. How would a snake move? Roll? Almost impossible.

The femur, also known as the thigh bone, is connected to the hip bone at the hip joint and the tibia bone at the knee joint. It is the longest and strongest bone in the human body, providing structural support and mobility.

The FIVE main functions of the skeleton are:

1. SUPPORT (skeletal muscle, tendons, internal framework etc)

2. PROTECTION (axial skeleton [ribcage, skull, spine], vital organs, etc.)

3. MOVEMENT ( joints, lever&pulleys, skeletal muscle, etc.)

4.BLOOD CELL PRODUCTION (red & white ceel production in bone marrow etc.)

5.MINERAL STORE (calcium stored in bones etc.)

== == A distribution of bones in different body parts is as follows: * 28 skull bones (14 facial, 8 cranial and 6 ear bones) * Hyoid bone of the neck (horseshoe-shaped) * 26 vertebrae (7 cervical, 12 thoracic, 5 lumbar, sacrum made from 5 fused vertebrae and coccyx made from 3 fused vertebrae) * 24 ribs, sternum or breastbone, shoulder girdle (2 clavicles and 2 scapulae) * 2 in arms (humerus), 4 in forearms (2 radius, 2 ulna) * 54 in the hands (carpus, metacarpus and digits) * 2 Hip bones * 2 in thighs (femur) * 6 in the legs (2 patella, 2 tibia and 2 fibula) * 52 in the feet (tarsus, metatarsus and digits)

The cranial cavity is the primary cavity of the skull; it contains the brain. In addition, the skull has four other pairs of cavities called sinuses. They are the frontal sinuses, maxillary sinuses, sphenoid sinuses, and ethmoid sinuses.

A tunnel-like passage through a bone is called a canal or a meatus. This structure allows for the passage of nerves, blood vessels, or other structures through the bone.

Osteoclasts break down bone, which will essentially increase the amount of free calcium in the blood stream. Osteoblasts "build" bones from the free calcium in the blood. Calcium is involved in muscle contraction, so if you lack the necessary calcium in your diet, your body will actually break down bone material in order to obtain the necessary calcium for proper muscle function.

The length of a person's foot is approximately 15 percent of his or her height. Use this proporation for your calculations: 15/100 = Length of Foot/x (person's height) This works best on a full grown individual for the ratio of body parts is slightly different in growing children. http://www.cyberbee.com/whodunnit/foot.html The length of a person's foot is approximately 15 percent of his or her height.

Cartilage cushions the ends of bones in the body, providing a smooth surface for joints to move without friction.

No, humans do not have hollow bones. Hollow bones are typically found in birds and are adaptations for flight, providing strength with reduced weight. Humans have a different bone structure that is denser and stronger to support our body weight.

They provide a rigid cage for the action of the diaphragm to allow the lungs to expand. Without ribs, your chest would simply "suck in" whenever the diaphragm moved down, and you would be unable to breathe. This is why a "sucking chest wound" is so dangerous.... it's allowing outside air to surround your lungs, instead of having your lungs fill with air.

It would be impossible to descride the location OS the bones without a diagram in any degree of accuracy as there are very many and they are in complicated arrangements. There is the Occipital bone (at the very back, articulates with the spine), 2 Parietal bones (at the top of the sides), 2 Temporal bones (at the bottom of the sides), 2 Zygomatic bones (the cheek bones), the Sphenoidal bone (butterfly shaped inside the head), the Ethmoid bone (very much hidden inside the facial bone structure), the Frontal bone (in the forehead), 2 Lacrimal bones (small ones in the eye socket) , the Nasal bone (the very top part of the nose), the Maxilla bone (the one behind the upper lip) and the Mandible bone (the jaw bone).

Babies can have up to 300-350 bones in their body after birth.

The outside of the ear, called the pinna or auricle, is made of cartilage not bone.

The bones (auditory ossicles) are located in the middle chamber of the ear.

All bones are formed from two types of bone structure. The shaft of long bones are composed of compact bone, and the inner parts of the shaft and each end is formed of spongy bone. In addition: in a fully grown adult all of the bones are formed of actual calcified bone. In a growing body however there are still section of Primary Cartillage which can grow. These section are in small plates (called Epiphesial Plates) in the Necks of long bones like the Femur. The neck of a bone like this is where the Head (usually a rounded part that is part of a joint) connects to the main lengthy part. The exact proportions varies far to greatly to put a number on but the vast vast majority of long bones are bone.

Support our body and protect our vital organs. Some of the bones of a skeleton are to protect organs such as the brain being protected by the skull, heart and lungs by the ribs etc and some of the bones are to provide movement such as those in the legs, arms, feet and hands in combination with muscles and tendons which connect them.

The bones of the visibly independent Toes (or Digits) are called the Phalangees (sig. Phalanx). The are named 1 to 5 starting at the Hallucis (big toe) and ending at the pinky toe. There are three boned in each digit (apart from the hallucis); the Proximal Phalanxe attaches to the Metatarsal of the toe; the Distal Phalanx is the tip of the toe (the one that hase the tow nai over it); the Middle Phalanxe is in between and is the oe mising from the hallucis. The joints between the proximal and middle and the middle and distal phalangees are Synnovial Hinge type and so only alow flextion and extension. The Joints between the metatarsals and the proximal phalangees are Synnovial Condyloid and so also allow some Abduction and Adductiuon. The metatarsals re usually considered to be foot bones but they could also be said to be toe bones. They are long thin bones that lie within the foot and do not appear to be separate from the outside.

24. A fetus has 33, but later the bones of the sacrum and coccyx fuse together.

Carbonated drinks, especially those high in phosphoric acid like colas, have been linked to lower bone mineral density over time. The phosphoric acid in these drinks can interfere with calcium absorption and contribute to bone loss, potentially increasing the risk of osteoporosis. It's important to consume these beverages in moderation and ensure an adequate intake of calcium and vitamin D to support bone health.

A skeleton provides structural support for the body, protects vital organs, and allows for movement through attachment to muscles. It also serves as a storage site for minerals such as calcium and phosphorus.
