Skeletal System

A trochanter (which is a large bump for muscle attachment - it is larger than a tubercle or tuberosity)

An amoeba does not need a blood system because its body has other organelles that it uses to survive. Plus a blood system is made up of many different cells and an amoeba consists of only one cell, that is why it is called a single celled organism.

Haversian canals in compact bone contain blood vessels, nerves, and lymphatic vessels that supply nutrients and remove waste products to and from osteocytes within the bone. They provide a network for communication and transportation throughout the bone tissue to maintain its health and function.

The sternum and the skull are examples of flat bones. These bones are thin and broad, providing protection for internal organs and serving as attachment points for muscles.

The double membrane that covers the lungs and lines the thoracic cavity is called the pleura. It consists of two layers: the visceral pleura attached to the lungs and the parietal pleura lining the thoracic cavity. The pleura produces a small amount of fluid that helps reduce friction during breathing.

Yes. Human ribs are bones, called flat bones, and are part of the axial skeleton.

The atlantoccipital joint which is a gliding joint, not as some people believe it to be a pivot joint. The pivot joint in this area is the atlantoaxial joint which is between C1 & C2 and doers not come into contact with the skull.

Small canals run through the bones known as osteons. These canals are formed by concentric layers of bone material and contain blood vessels and nerves that supply nutrients to the bone tissue. The canals help nourish and maintain the bone's health.

It is not normal for your collarbone to be constantly popping. This could indicate an issue with the joint or surrounding structures and should be evaluated by a medical professional to determine the underlying cause and appropriate treatment.

An average adult has around 206 bones in their body. This number may vary slightly depending on factors like age and individual anatomy.

Periosteum. The periosteum is a dense fibrous membrane that surrounds the outer surface of bones and is responsible for generating new bone tissue, contributing to the growth in thickness of long bones.

Treatment for fluid in the mastoid bone typically involves antibiotics to treat any infection present, as well as a procedure called mastoidectomy to drain the fluid. Surgery may be necessary to remove infected tissue and repair any damage. It's important to consult with an ENT specialist for proper evaluation and treatment.

Ideal body measurements can vary based on individual preferences and body composition. However, a general guideline for a 5'2 woman with medium bone size could include a waist measurement of around 26-29 inches, hip measurement of around 36-39 inches, and a bust measurement of around 32-35 inches. It's important to focus on overall health and fitness rather than specific body measurements.

A knot under your rib cage could be a muscle spasm, a hernia, a cyst, or even an enlarged organ like the liver. It's best to see a doctor for an accurate diagnosis and appropriate treatment.

The bone made up of the ilium, ischium, and pubis is the hip bone, also known as the os coxae or innominate bone. It is a large, flat bone that forms part of the pelvis.

Parathyroid hormone (PTH) and calcitonin are the main hormones involved in regulating calcium levels in the blood. PTH helps increase calcium levels by promoting its release from bones and absorption from the intestine, while calcitonin helps decrease calcium levels by promoting its deposition in bones.

internal skeleton is meaning that the organism have backbone. So that means that insect is not part of it. Also examples such as jellyfish, squid, octopus, etc. does not fall in internal skeleton group.

My dictionary give this definition -

- the normal investment of bone, consisting of a dense, fibrous outer layer, to which muscles attach, and a more delicate, inner layer capable of forming bone.

The triangle-shaped bone in your upper back is called the scapula, which is also known as the shoulder blade. It is an important bone that connects the humerus (upper arm bone) to the clavicle (collarbone) and helps in the movement of the shoulder joint.

Your skeletal system can be compared to a factory because it provides structure and support for your body, like the framework of a building. It also produces red blood cells, stores minerals and releases them when needed, similar to how a factory stores and distributes raw materials. Additionally, just like a factory, the bones in your skeletal system work together in a coordinated manner to help you move efficiently.

The tough, tight-fitting membrane covering the surface of bone is the periosteum. It consists of dense irregular connective tissue and serves to protect the bone, provide a site for muscle attachment, and aid in bone repair and growth. The periosteum also contains blood vessels and nerves that supply the bone.

"Growing pains" typically refer to musculoskeletal discomfort experienced in children during growth spurts. While rib pain can occur in children due to cartilage inflammation or muscle strain, it is less common to attribute it solely to growing pains. It is important to consult a healthcare provider to properly diagnose and address any rib discomfort.

The arm is divided into three general regions. The first region is the upper arm. It consists of a single bone called the humerus.The second region is the lower arm. It consists of two bones, the radius and the ulna.The Radius is closest to your thumb. There aren't and bones actually connected.So it's the radius.... =] hope I helped!! :)

That bone is called as ulna. This bone takes part in the elbow joint. This is thick at upper end and gets thinner as it goes down. The other bone called radius takes part in the wrist joint. That is the ultimate design by the nature. How it works is beyond the scope of this question.

Babies have more bones so their bodies are more flexible to fit through the birth canal. As the baby grows the bones join together. A good example of this is the babies head, the bones in the skull are separated until about 18 months. The spaces between these bones in the skull is what is often called a soft spots.
