Skeletal System

The skeletal system provides definite shape and mechanical support to the body, and it also helps in movement and locomotion. Ask questions about the skeletal system and bones here.

Spaces or soft spots in the cranium that allow for the enlargement of the skull as brain growth occurs?

Fontanelles are spaces between the bones in an infant's skull that allow for brain growth and development. These soft spots allow the skull to expand as the brain grows rapidly in the early years of life. Fontanelles eventually close as the bones in the skull fuse together.

How does popping your bones affect your body?

Popping your bones, also known as joint manipulation or cavitation, is the release of gas bubbles in the synovial fluid within the joint. It does not have any harmful effects on the body and is generally safe. However, excessive or forceful popping may potentially lead to joint instability or irritation over time.

What happens to the diaphragm when a person inhales?

The diafragm moves downward and the intercostal muscles contract pushing the chest outward and upward causing negative pressure in the lung structure - air will allways move from a high pressure area to a low pressure area, hence, into the lungs.

What are the two stringy cartilage-like things at the back of the knee called?

They are called menisci, which are C-shaped cartilage structures that help cushion and stabilize the knee joint. The menisci help distribute body weight and reduce friction between the bones in the knee.

Which bone cells produce new bone tissue if a bone is broken?

Osteoblasts are bone cells responsible for producing new bone tissue during the healing process of a broken bone. They lay down new bone matrix that eventually hardens to form a callus, which bridges the gap between the broken bone ends.

When the epiphysis closes on a bone the bone can no longer grow in what?

When the epiphysis closes on a bone, the bone can no longer grow in length. The closure of the epiphysis marks the end of longitudinal bone growth, but the bone can still increase in thickness through a process called appositional growth.

Why is it that cartilage cells proliferate at the growth plate or epiphyseal plate but this layer does not get thicker over time?

Cartilage cells at the growth plate proliferate and divide rapidly to contribute to bone growth and elongation. However, as these cells divide, they also undergo a process called hypertrophy, ultimately leading to mineralization and replacement by bone tissue. This turnover process prevents the growth plate from getting thicker over time.

What are the three bones that make up the wrist and hands?

The three main bones in the wrist are the radius, ulna, and carpal bones. In the hand, the main bones are the metacarpals and phalanges.

Why are the tiniest bones in the human body important?

The tiniest bones in the human body are found in the middle ear and are known as the ossicles - the malleus, incus, and stapes. These bones play a crucial role in transmitting sound vibrations from the eardrum to the inner ear, allowing us to hear and process sound effectively. Without these bones, our auditory system would not function properly.

What if you have a big bump below your knee?

A big bump below your knee could be due to various reasons such as injury, inflammation, cysts, or growths. To determine the cause and appropriate treatment, it is important to consult a healthcare professional for evaluation and diagnosis.

What is segmental instrumentation in the musculoskeletal system?

Segmental instrumentation in the musculoskeletal system refers to the use of implants or devices that stabilize a specific segment of the spine or limb. This type of instrumentation is commonly used in spinal fusion surgeries to provide stability and promote fusion of the affected segment. It can help correct deformities, support the spine, and improve overall function and mobility.

Why is the red marrow bone important?

Red marrow produces red blood cells (RBCs), white blood cells (WBCs) and cell fragments called platelets. RBCs carry oxygen through out the body, WBCs fight off infections by bacteria and viruses, other "invaders" and platelets are necessary for blood clotting.

How many layers thick is a capillary?

Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.

What body system do the radius belongs to?

The radius belongs to the skeletal system. It is the lateral bone in the forearm.

What muscles attach to which bones?

The muscles of the body attach to bones via tendons. Different muscles attach to different bones to create movement at various joints in the body. For example, the biceps muscle attaches to the radius bone in the forearm, while the quadriceps muscle group attaches to the femur bone in the thigh.

What is another name for skull sutures?

The cranial sutures are fibrous joints, also known as synarthroses.

Do animal bones have fat in them?

Yes, animal bones can contain some amount of fat, mainly in the marrow found inside the bone cavities. Bone marrow serves as a nutrient-rich fatty tissue that assists in various bodily functions, such as energy storage and blood cell production.

What does humerus mean in the skeletal system?

The humerus is the bone in the upper arm that connects the shoulder to the elbow. It is the largest bone in the arm and plays a crucial role in arm movement and strength.

What can you do to stop your ribcage from showing?

To reduce the visibility of your ribcage, you can focus on gaining overall body weight and muscle mass through strength training exercises that target your chest, back, and shoulders. Incorporating a balanced diet rich in protein and healthy fats can also help in building muscle and adding a layer of fat to the ribcage area. It's important to consult with a healthcare professional or nutritionist to create a safe and effective plan for achieving your desired body composition goals.

Is your kneecap the roundest bones in your body?

Yes, the patella (kneecap) is one of the roundest bones in the human body. It is a small, flat, triangular bone that sits in front of the knee joint and helps protect the knee and aid in movement.

What enables us to stand erect?

Standing erect is made possible by the complex interplay of muscles, bones, and ligaments in our body, especially in the spine and lower extremities. Key factors include the alignment of the vertebrae, the strength and coordination of muscles, and the balance maintained by the inner ear and proprioceptive senses. Additionally, the development of bipedalism in human evolution has led to adaptations that support our ability to stand upright.

What are movements along the sagittal plane that decrease the angle between two bones?

Flexion is the general term for movements that decrease the angle between two bones; however, in the sagittal plane, the special term "adduction" is used for movements that decrease the angle between the limb and the midline.

Is the pectoral girdle a part of the axial division of the skeletal system?

If a straight line was made from the top of the skull straight down the spine to the ground, as in an axial division, the left side of the body including the pelvis would be a mirror image of the right side, so the body can be called bi-laterally symmetrical.

What is Chondromalacia patellae?

Chondromalacia patellae is most often found in young women where the knee caps (patellae) develop a condition that softens the cartilage. The added description of severe diffuse thinning indicates that it has progressed to a larger degree. A person with this condition may experience significant pain when walking, or doing other activities like sports.

What could you infer about an animal from fossil or jaw bone?

You can tell weather the animal is a carnivorousness, herbivorous or what type of group it is put in E.G (mammals, reptiles). You can tell what age it is by looking at its teeth and what injuries it suffered when it was alive.
