Skeletal System

The epiphysis is the rounded end of a long bone, and it contains spongy bone tissue that provides structural support and helps in shock absorption. The epiphysis also plays a role in bone growth and development by containing red bone marrow, which is responsible for producing blood cells.

The intervertebral discs are made up of fibrocartilage. Fibrocartilage is a type of cartilage that contains both collagen fibers and cartilage cells (chondrocytes), providing the disc with strength and flexibility to absorb shock between the vertebrae in the spine.

The joint between the skull bones is known as a suture. Sutures are fibrous joints that are held together by dense connective tissue. They allow for minimal movement between the bones of the skull to protect the brain and maintain the structure of the head.

Non-axial joints are joints where the bones have limited movement mainly in a plane such as gliding joints in the wrists and ankles. These joints allow for simple movement without rotation, like sliding or gliding movements. Non-axial joints provide stability and support for the body.

Osseous edema is a condition where there is an accumulation of excess fluid in the bone, typically due to inflammation or injury. This can lead to pain, swelling, and changes in bone density on imaging studies. It is commonly seen in conditions like stress fractures or osteoarthritis.

Obturator foramen.

Fusion of the rami of the pubis anteriorly and the ischium posteriorly forms a bar of bone enclosing the obturator foramen.

The human hand has 27 bones: the carpus or wrist account for 8; the metacarpals or palm contains five; the remaining fourteen are digital bones; fingers and thumb. The human foot has 26 bones in the hind-foot, the mid-foot, and the forefoot.

The mandible is found in the jaw and is part of the skull so can be classed as a flat bone but has also been described as irregular due to the shape. The clavicle is a flat bone and supports the shoulder but again other sources have described it as a short bone. Conflicting evidence for each sorry.

Each metacarpal bone consists of a base, a shaft, and a head. The base attaches to the carpal bones in the wrist, the shaft is the long middle portion of the bone, and the head connects to the phalanges in the fingers.

The patella is the bone commonly known as the knee cap. It sits in front of the knee joint and helps protect the joint and provide leverage for the muscles that extend the knee.

The depression on the ulna into which the humerus inserts is called the trochlear notch. This forms the hinge joint known as the elbow joint.

The weight of the femur varies by size. Also, is it fresh, or dry? Dried, bleached bones will weigh less than ones recently removed from a cadaver. I would estimate a fresh adult thigh bone to weigh about five pounds.

A baby is born with approximately 300 bones in their bodies. As we get older our bones fuse together and by the time we reach adult hood we have 206.
Babies are born with over 300 bones but when you get older they start to join together so when your an adult you will have 206 bones in your body

The knee joint is a hinge synovial joint, allowing for flexion and extension movements. It is composed of the femur, tibia, and patella, with structures such as ligaments and menisci providing stability and support.

Cats are carnivores while dogs are omnivorous. Another variation between their skeleton is their skeleton size. A cat has a smaller skeleton compared to a dog. The main difference can be seen from their skull. A dogs skull is bigger and longer than a cat and a cat's skull can be identified from the number of cheek teeth.

No, the bony callus is primarily composed of spongy (cancellous) bone. It forms during the healing process of a bone fracture and helps stabilize and repair the bone. The bony callus eventually remodels into compact bone over time.

Yes, osteoblasts from the medullary cavity can migrate to the fracture site to participate in bone healing. When a bone fractures, osteoblasts are recruited from various sources, including the medullary cavity, to produce new bone tissue and facilitate the repair process.

No- bone marrow is the source of all your red blood cells (which carry oxygen), platelets (which help clot your blood) and white blood cells (which fight infections). Although you can replace your red cells and platelets with blood transfusions, you cannot replace your immune system, so you would contract infection after infection, and eventually that would lead to death. A condition that causes this would be aplastic anaemia.

Yes, bones are classified by their shape. The main categories of bone shapes include long bones (e.g. femur), short bones (e.g. carpals), flat bones (e.g. skull), irregular bones (e.g. vertebrae), and sesamoid bones (e.g. patella). Each shape serves a particular function in the body.

no because it has your nose and your chin and they poke out The skull is highly irregular in shape; the top of the skull in particular can develop irregularities during development as a child.

The action of the supraspinatus is to stabilize the shoulder joint and help prevent downward location of the humerus and to assist in abduction.

An air space within a bone is called a sinus. Sinuses are cavities located within certain bones of the skull, such as the frontal, maxillary, ethmoid, and sphenoid bones. They are lined with mucous membrane and help to lighten the skull and resonate sound during speech.

Cancellous bone. It is the less dense and more porous type of bone tissue found in the interior of bones.

Yes and no, there is a joint (or joints as you have two) in your waist line called the sacroiliac joint, where your sacrum meets your ilium. Unless you've studied bones that answer might not help so... The sacrum is a bunch of fused vertebrae at the very end of your spine, its right above your tail bone, and you have an ilium on either your two innominates (which form the body of your pelvis), these ilia are more or less the part of your pelvis that you can see in your hips. Other than that the nearest joint I can think of is the joint made where the femoral head meets the acetabular fossa (the top of your legs, often called the "hip joint"). Hope this helps!
