Skeletal System

Examples of joints that can become synostosis with age include the skull sutures and the joint between the two pubic bones in the pelvis. These joints typically start out as cartilaginous joints in early development, but as we age, they can progressively fuse together, resulting in synostosis.

There are a number of serious possibilities, ranging from severe lung infection to chronic pulmonary disease. Please see your physician and ask him to have the x-rays examined by a specialist.

The spine, or spinal column, is made up of a series of joints called gliding joints and are made of dense irregular connective tissue which is strong and allows for only slight movement in comparison to freely movable joints, like those in the arms and legs.

The tibia and fibula are connected by ligaments, which are strong bands of tissue that hold the bones together at the knee and ankle joints. Additionally, there are also muscles that attach to both bones, providing stability and allowing for movement of the lower leg.

The "true" ribs are the first 8 ribs of the horse's rib cage (there are 18 total ribs). They are the true ribs because the attach to both the vertebrae above them and the sternum below. I found this in a book-Chapter 35 of Saddles by Russel H. Beatie. Hope this helps.

The Inuit people are known to have some of the thickest and strongest skulls, believed to be an adaptation to their icy environment and lifestyle. This unique skull structure has been attributed to their ancestors surviving in challenging conditions.

No, a broken bone does not feel the cold more than non-broken bones. However, some people may experience increased sensitivity to temperature changes near the site of the injury due to inflammation or nerve damage associated with the fracture.

The femur is the largest bone in the human body, and the stirrup is the shortest bone in the human body.

They protect your heart and lungs. Just to add to that, your ribs protect your internal organs such as your stomach, heart, and lungs so that when somethings happens that hurts you, like a punch in the stomach, your heart and lungs don't take all the pressure and basically crush.
To protect the organs underneath, otherwise when you press on your ribs it would just be flat and you could squish vital organs

The elastic tissue between each bone in the spine is called as intervertebral disc. It allows movement of vertebral bodies and also acts as shock absorber to the spine.

Growing pains are typically described as a dull, aching discomfort in the legs, rather than a sensation of bones coming apart. While the exact cause of growing pains is not fully understood, it is believed to be related to the rapid growth of muscles, tendons, and bones during childhood and adolescence. If you are experiencing severe or persistent pain, it is best to consult with a healthcare professional for a proper evaluation.

Osteoclasts are known for their ability to break down bone tissue through a process called bone resorption. They contain specialized enzymes and proteins for this purpose, such as cathepsin K, matrix metalloproteinases, and vacuolar ATPase. Osteoclasts play a crucial role in bone remodeling and maintaining bone health.

All ribs have the potential to grow back if removed properly. There are common procedures which remove humps on ribs by cutting away a length of the rib, which will grow back into place within 2 to 3 months. The membrane which covers the rib must be left completely intact in order for this to happen.

The heads of the phalanges are the rounded ends of the finger bones that articulate with the bones of the hand. These heads are what form the knuckles when making a fist. The knuckles are joints where the metacarpal bones meet the phalanges.

The bones of the skull are separated into two parts: the bones of the face, the bones of the cranium. This would include the frontal, temporal, parietal, sagittal, sphenoid, and ethmoid bones. There may be a couple more, but these are the ones I know off the top of my head.

When not exercising, bone density can decrease over time due to lack of stress being placed on the bones. Weight-bearing exercises and resistance training are important for maintaining and increasing bone density by stimulating bone growth and strength. Without regular exercise, bones may become more fragile and susceptible to conditions like osteoporosis.

The elements of most bones contain osseous tissue as well as marrow, endosteum, periosteum, nerves, blood vessels and cartilage.

Hydroxylapatite, also called hydroxyapatite is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities.

The metacarpal bones are found in the hand, between the wrist and the fingers. There are five metacarpal bones in each hand, numbered one through five starting from the thumb side. These bones form the framework of the palm and provide structure and support for the hand.

A knee joint is a hinge joint, allowing movement in one plane (flexion and extension). It is made up of the femur, tibia, and patella bones, along with ligaments and cartilage for stability and support.

Ligaments contain collagen fibers that become more pliable and elastic with increased temperature. The warmth helps to relax the collagen fibers, making the ligaments more flexible. This increased flexibility can help prevent injuries during physical activity.

Apparently a Long Bone. I could be wrong

That is incorrect. Long bones are those you find in the legs and arms. The clavicle is a flat bone.

** This answer is incorrect, the actual bone is characterized as a irregular bone.**

The bone matrix is composed of two main components: organic (collagen fibers and proteins) and inorganic (mineral salts like calcium and phosphate). The organic components provide flexibility and tensile strength, while the inorganic components provide hardness and rigidity to the bone.

You have a malleus, incus and stapes in each ear which makes up your 6 but also the hyoid bone (around the top of your throat, holds the larynx and other structures in place) is usually counted in with these bones making 29 in all

Who said there are 28 cranial / facial bones? The cranial facial complex is composed of 22 bones. The other bones hyoid, malleus, incus, stapes etc. are not considered part of the cranial facial complex.

Well the humerus is the longest arm bone but in each arm there are 2 long bones.

edit: depends on the definition of arm, but at least THREE:

Shoulder (2):

-clavicle

-scapula

Upper arm (1):

-humerous

Lower arm (2):

-radius

-ulna

Wrist (13):

-scaphoid

-lunate

-triquetral

-trapezoid

-capitate

-hammate

-metacarpals (5)

Fingers (14):

-proximal phalanges (5)

-intermediate phalanges (4 [none in thumb])

-distal phalanges (5)

I is a ditty or acronym to remember the wrist bones but it is never lowere tillies pants mother might come home

That helps in recalling navicular, lunate, triquetrum, pisiform, greater Multongular, lesser Multongular, …capitate hamate. I learned it 50 years ago in nursing school.
