Skeletal System

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!

This called a suture. It is an immovable joint where two bones in the skull meet to form this joint.

Treatment for fluid at the base of the spine depends on the underlying cause. It may involve medications to reduce inflammation, physical therapy to strengthen the muscles supporting the spine, or drainage procedures to remove excess fluid. In some cases, surgery may be required to address the issue. Consulting with a healthcare professional is recommended for proper diagnosis and treatment.

The membrane between the ulna and the radius is called the interosseous membrane. It helps to stabilize the bones of the forearm during movement and provides a surface for muscles to attach.

Compact bone tissue is adapted to support weight and withstand tension stress due to its dense structure and arrangement of osteons. These osteons are aligned in the direction of stress to provide strength and stability to the bone. This compact arrangement makes it ideal for weight-bearing and resisting tension.

The vagus nerve (cranial nerve X) supplies innervation to most thoracic and abdominal organs, including the heart, lungs, stomach, and intestines. It plays a key role in regulating many vital functions such as heart rate, digestion, and breathing.

No, the number of bones in the human body remains the same as we grow older. A baby is born with about 270 bones, but many of these fuse together as the body matures, resulting in the adult skeleton of around 206 bones.

The femur bone is composed of osseous tissue (bone tissue) which includes compact bone and spongy bone. Additionally, the femur contains blood vessels, nerves, and bone marrow.

Production of Vitamin D - Some of the ultraviolet light striking the skin passes through the melanin sunscreen and causes a chemical change in the blood leading to the formation of vitamin D. This vitamin is required for the body to absorb calcium from the intestine. Calcium is essential for the development of teeth and bones.

According to Wiki, the Phalanx is a long bone

Cartilage is the flexible substance at the ends of bones in joints. It acts as a cushion and facilitates smooth movement of the bones. It also helps in absorbing shock and reducing friction during movement.

The meniscus is the cartilage surrounding the lower part of you knee cap, it acts as cushioning between the knee cap and tibia/ fibula. Usually when when you injure your meniscus it is a tear, and it almost always causes pain. Also the meniscus can't regrow itself so if you have a grade 3 tear (a tear that reaches the edges) you will probably need surgery. A grade 2 tear is a tear inside the meniscus that doesn't go all the way through. Grade one is very mild and usually isn't felt until (if it is ever) made worse.

The mucous membrane-lined cavities found in several bones surrounding the nasal cavities are called paranasal sinuses. These sinuses include the frontal, maxillary, ethmoid, and sphenoid sinuses. They help to lighten the skull, produce mucus, and regulate the resonance of the voice.

In the absence of infection or any other complication, the sternum will be fused enough to resume light activity in 6-8 weeks. Absolutely no strenuous activity or heavy lifting should take place until 6 months after surgery. Consult your physician regarding long-term weightlifting guidelines. Most heart patients should never lift more than 50 lbs. regardless of how long they are post-op. This puts undue stress on the sternum and on the heart itself.

Displacement of lumbar intervertebral disc without myelopathy refers to a condition where the disc between two lumbar vertebrae shifts or protrudes, but does not cause compression or damage to the spinal cord. Symptoms can include back pain, numbness, tingling, or weakness in the legs. Treatment may involve rest, physical therapy, pain management, and in severe cases, surgery.
