Skeletal System

yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.

The medullary cavity of a long bone forms during development through a process called endochondral ossification. This process involves the replacement of cartilage with bone tissue, with osteoclasts breaking down the center of the bone shaft to create the cavity where bone marrow will eventually reside.

No, a pivot joint and a biaxial joint are not the same. A pivot joint allows only rotating movement around one axis, like the movement of the head from side to side. A biaxial joint allows movement in two perpendicular axes, such as the wrist which can move up and down as well as side to side.

The coccyx is in the sacral section of the spine.

Some examples of living things that do not have a skeleton include jellyfish, worms, octopuses, and insects. These animals have other structural support systems in place of a skeleton, such as exoskeletons or hydrostatic skeletons.

Yes, it feel like you had broke it. I broke my wrist back in 2000. I was

told that I had a vitamins K deffiency. I was also told I had Giant-Cell

tumors. I had to have about 2 or 3 inches of my ulna replaced at my wrist.

I have been haveing trouble with my knees and shoulder, hips,and the small

bones in the palm of my hand. I had a bone denisity test and in a months time I lost 2 percent of my bone. For the past 6 or 7 months my brain has pains behind my

both ears. I don't have the money to go have alot of test done. Do you think

I need a certain vitamins?

Swelling on the shin bone that persists for four years could be due to various factors such as chronic inflammation, soft tissue damage, an underlying medical condition like arthritis, or inadequate treatment of an original injury. It is important to consult with a healthcare professional for a proper diagnosis and appropriate treatment plan to address the ongoing swelling.

The point where two or more grooves meet is called a point of convergence. It is a critical feature in forensic analysis of tool marks or firearms, as it can help determine the direction and sequence of tool movements or bullet trajectories.

Having the lungs inside the rib cage provides protection against external trauma and helps maintain a stable environment for the lungs to function optimally. Being close to the heart allows for efficient oxygen exchange between the lungs and blood, facilitating the circulation of oxygen-rich blood throughout the body.

Mottled bone in humans refers to a condition where the bones have a patchy or blotchy appearance when viewed on imaging studies like X-rays. This can be an indication of various underlying conditions such as osteoporosis, osteomalacia, or other metabolic bone diseases. It is important to consult a healthcare professional for proper evaluation and management.

The meniscus is the cushion within the knee joint.

Subsystems interact by sharing information, resources, and outputs with each other to create a functioning system. Each subsystem has its own specific task or function, and when they work together efficiently and effectively, they contribute to the overall operation and stability of the system as a whole. Communication and coordination between subsystems are essential to ensure that they align their efforts towards achieving the system's objectives.

The bones in the hands are called metacarpals, while the bones in the feet are called metatarsals.

Yes, spongy bone does have the capability to produce red blood cells through a process called hematopoiesis. The bone marrow located in the spongy bone contains stem cells that can differentiate into red blood cells, white blood cells, and platelets.

Firstly, the spine is separated into three separate types of vertebrae: the first seven starting at the base of the skull are the cervical vertebrae (and the first specifically being the atlas and second the axis), the next twelve are the thoracic vertebrae, and the last five are the lumbar vertebrae. The spine ends with the large sacrum bone and then ends with the coccyx (tailbone). between these vertebrae are disks of hyaline cartilage.

The vertebral column houses the spinal cord. The spinal cord branches out between each vertebrae with nerves that lead to different areas of the body.

A bone that is partially broken is typically referred to as a "hairline fracture" or a "stress fracture." These are small cracks in the bone that do not completely break it into two separate pieces. Treatment usually involves rest and immobilization to allow the bone to heal.

Clench your buttcheeks as hard as you can. This always works for me. Check out this website: http://ask.metafilter.com/92677/I-think-my-tail-bone-pops-when-I-stretch-You

Several other people mention the same thing...

To add to what the person above said, I pop my tailbone area or coccyx all of the time. I do this by sitting in a chair, crossing my ankles, leaning slightly back, and stretching my ankles apart from each other which seems to somehow "open up" or flex my tailbone area. I also get the same results from ankle crossing and pulling when sitting on the floor and leaned back with all of my weight on my tailbone area.

This description is quite vague and could variety on a lot of factors such as your weight, activities, does it hurt after you have eaten, aanndd if there was any recent trauma to the area. If it hurts just as much while breathing and also pressure, then i would assume a fracture. But could also possible be a muscle attachment problem

Although a broken femur bone is a serious injury that can lead to complications such as blood loss or infection, it is not typically fatal in and of itself. Prompt medical attention and appropriate treatment can help prevent any life-threatening outcomes associated with a broken femur bone.

it protects the internal organs such as brain,heart and lungs....

it provides support...with out the skeletal system we would not be able to stand.....

Bones provide the structure for muscles to attach so that our bodies are able to move.....but bons are connected to muscles by tendons

The liver is located under the right rib cage and extends into the upper right quadrant of the abdomen.

In general, bones are similar in structure between men and women. However, women tend to have lower bone density and smaller bones compared to men, which can affect their risk of developing osteoporosis. Hormonal differences play a role in these differences.

The putting-out system, also known as the domestic system, involved merchants supplying raw materials to skilled workers to be completed in their homes. Once finished, the goods would be collected by the merchants for sale. This system allowed for production to be decentralized and completed at a small scale in individual homes.

No, they are not. The intercondylar fossa is found on the femur, the greater trochanter is on the femur as well, and the tibial tuberosity is located on the tibia. None of them are bone markings of the humerus.
