Skeletal System

The three places where cartilage is found is in the knee, ankle and elbow

Bones are covered with a special tissue called periosteum. Periosteum helps protect bones and provides a surface for muscle attachment. It also contains blood vessels that supply nutrients to the bone.

An adult human body has 206 bones. Each foot has 26 bones. That's slightly more than 25%.

Fracture of the temporal bone causes bleeding which can be medial to an intact tympanic membrane, from the middle ear through a rupture of the tympanic membrane, or from a fracture line in the ear canal. Hemotympanum gives the tympanic membrane a blue-black color. Usually, there is a communication with the subarachnoid space through the fracture line. Often, there is cerebrospinal fluid otorrhea. Most of the fractures of the temporal bone are longitudinal (80%)to the long axis of the petrous pyramid, only 20% are transverse. Longitudinal fractures usually extend through the middle ear into the ear canal, causing rupture of the tympanic membrane. Approximately 35% of logitudinal fractures produce a sensorineural hearing loss, and approximately 15% produce facial parlysis. Transverse fractures extend across the cochlea and fallopian canal, causing a profound permanent sensorineural hearing loss and a facial paralysis. These fractures are usually well demonstrated with CT.

Spiral bone fractures, or any fracures for that matter, could be caused by malnourishment of the bones. Weak bones=more breaks and fractures. Bone injury is almost always a result of trauma, however.

There are 27 bones in your hand: 8 carpals, 5 metacarpals, and 14 phalanges (each of your fingers has 3 phalanges in them - proximal, middle, and distal. However, there are only two phalanges in your thumb, proximal and distal.)

The skeletal system provides support and structure for the body, protects vital organs, allows for movement through muscle attachment, and stores minerals that are essential for bodily functions. It also plays a crucial role in the production of blood cells.

If you have pain under your left rib cage, you should consider seeing a gastroenterologist who specializes in digestive system disorders, or a primary care physician who can evaluate your symptoms and refer you to a specialist if needed. It's important to seek medical advice to determine the underlying cause of the pain.

Bones are hard because they must have the mechanical strength to support the weight of the animal (or the required proportion thereof, like in a whale) and facilitate the movement of that animal. Imagine trying to stand up if your leg bones were made of soft rubber. You couldn't. And could you reach across the table to pick up a glass of milk if your arm bones were made of that same soft rubber? Nope. Not happenin'.

They are hard because they contain a large proportion of calcium and phosphorus. In addition of providing leverage for movement (as noted above), they also protect parts of the body, like the brain, spinal cord, lungs, heart, and other internal organs. They also store minerals and make blood.

posobly, depends how hard u hit it no it cant kill you, it actually doesn't even do any damage to your bones or nerves, dont believe someone who can't spell possibly

The pons contains nuclei that relay signals from the cerebrum to the cerebellum, and nuclei concerned with sleep, hearing, equilibrium, taste, eye movements, facial expressions, facial sensation, respiration, swallowing, bladder control, and posture.

no...this is what muscles, joints, ligaments, and tendons are for! Although rare, yes bones can be elongated by surgery. If a child at a certain age has a growing problem this surgery has been done. On the norm no you can't stretch bones.

The important organic components of bone include collagen, which provides strength and flexibility, and non-collagenous proteins, which regulate mineralization and bone formation. These organic components work together with inorganic minerals like calcium and phosphate to give bone its structure and functionality.

This pattern indicates a conductive hearing loss. The air-bone gap of 45 dB suggests that there is a problem conducting sound through the middle ear. Bone conduction thresholds are normal, which means the inner ear (cochlea) is functioning properly.

A bone spur (also called osteophyte)is a shart protrusion from a bone. Bone spurs can be extremely painful, quite difficult to identify, and very small in size, but they are large enough to pinch at tiny nerves which causes pain. =What Causes Bone Spurs?= Calcium is the most abundant mineral in the body but may also be the most deficient. The amount of calcium that we absorb from our food varies widely. Our age is one factor. An adolescent may absorb up to 75% of the calcium obtained from foods, while in adults the maximum absorption rate ranges from 20% to 30%. Even though our bones feel solid and seem permanent they're just like any other body tissue - they're constantly being broken down and formed again. In an adult, 20 percent of bone calcium is withdrawn from bones and replaced each year. Thus, every five years the bones are renewed. Calcium is found in the extra cellular fluids and soft tissues of the body where it is vital to normal cell functioning. Much of the calcium in soft tissues is concentrated in muscle, although it is contained in the membrane and cytoplasm of every cell. When the body is deficient of calcium it begins to leach calcium from the bones. In many people this happens to be in the heel of the foot or some other weak area of the body. As the calcium is being leached, it forms an eruption (similar to a volcano). This eruption is the bone spur.

Phlanges are bones of the fingers and toes. There are three phlanax sections in each finger and toe except the thumb and big toe,which have only two bones. Twelve bones of the four fingers, two bones in the thumb of the right hand, and twelve bones of the four fingers, two bones in the thumb of the left hand. That makes 14 phlanges of each hand. And 28 for both. But only if you were born with all of your fingers.

A human rib cage can withstand varying amounts of pressure and weight depending on the individual and their physical condition. On average, a human rib cage can support a weight of roughly 180-200 pounds. However, exceeding this weight can cause damage or fractures to the ribs.

Sternum is the scientific term for the breastbone.

When the sutures of the skull are no longer visible, it often indicates that the bones of the skull have fused together, typically occurring in adulthood. This fusion is a natural process called cranial ossification, which helps provide stability and protection to the brain.

The main mineral found in bone is hydroxyapatite, which is a form of calcium phosphate. This mineral provides strength and rigidity to bones.

The patella is a small, flat bone located in front of the knee joint. It acts as a protective shield for the knee and helps to increase the leverage of the quadriceps muscles. The patella also aids in the extension of the knee joint during movement.

Bone marrow comes in two categories, red and yellow. Red is common in young children's bones. It creates red blood cells. As you become a teenager, you have less red and more yellow bone marrow. Yellow bone marrow stores fat so it can later be used as energy, but there are still some bones that contain red bone marrow.

Your teeth are considered part of the skeletel system but are not classified as bones as they are made of enamel and dentin

The Femur is the strongest bone in the body.
