Skeletal System

Yes, the wrist has a range of motion that allows it to rotate completely in a circle. This rotation is made possible by the articulation between the radius and ulna in the forearm and the carpal bones in the hand.

A. Support

The skeleton provides the framework for the body. Bones provide the basic shape and structure for the body. What do you think we would look like if we didn't have bones? Pretty silly right? The bones are like the beams inside of a building, and all of our organs, muscles and skin are organized around the bones, just like the walls of a building. The mandible and maxilla support the tooth. Bones of the lower of the lower limbs, pelvis and vertebral column hold up the body.

B. Protection

The skeleton protects organs in the body. Bones can cover and protect many of out major organs. They are like an armor that protects our insides.1. cranium: protects the brain

2. ribs/sternum: protects the lungs, heart and some digestive organs

3. pelvis: protects and supports the digestive and reproductive organs

4. spinal column: protects the spine

C. Blood Cell Production.

Inside of the long bones in our bodies, there is a cavity that is filled with a substance called Bone Marrow. In this tissue, new blood cells are produced, and damaged blood cells are repaired. Red bone marrow produces red blood cells, white blood cells and other blood elements.

D. Movement.

The bones are the levers that help the body move in different directions and in different ways. The bones by themselves can't move without the muscles that are connected to them.

E. Mineral Storage.

Mineral is a substance that the body needs to carry out all of our bodily functions like thinking, breathing and moving around. One of the minerals that the body needs is calcium. Calcium is a major part of bone, and this is where the body stores its calcium. It is very important to make sure you eat enough calcium each day because if you don't get enough calcium, your body will take the calcium it needs from your bones. The less calcium the bone has, the weaker it will become.

F. Fat Storage.

Triglyceride (fat) is stored in the form of yellow bone marrow in the medullary cavity of bone. This fat is used by body as a source of energy whenever required.

Unspecified obstruction of renal pelvis and ureter refers to a blockage in the tubes that carry urine from the kidney to the bladder, without specifying the cause or location of the obstruction. This can lead to urine build-up in the kidney, causing pain, infection, and potential damage to the kidney if left untreated. Further evaluation may be needed to determine the underlying cause of the obstruction.

The name of the joint that is between C1 & C2 is the atlantoaxial joint. C1 is the atlas and C2 is the axis. The type of joint is called a pivot joint, and often referred to as the no-no joint, because it is used to rotate your head left and right, as in saying 'no'.

The curved area on the hip bone below the posterior inferior iliac spine is called the greater sciatic notch. It is a large notch that is located on the posterior aspect of the hip bone and forms part of the greater sciatic foramen.

Pirates are most famously associated with the skull and crossbones flag, also known as the Jolly Roger. This flag would often be hoisted to strike fear into their victims as they approached.

Yes, the ulna is a bone that is part of the appendicular skeleton. It is one of the two bones in the forearm, with the other being the radius. Together, the ulna and radius play a crucial role in forearm movement and support.

The majority of the bone you see is actually extracellular matrix but dispersed within it are cells called osteoblasts. These are usually either individual cells or in very small groups but they are not in any specific locations within the bone.

The atlas (C1) is the cervical vertebra that holds up the head. It is designed to support the weight of the skull and allow for a wide range of motion for movements such as nodding.

In general, bone names are not capitalized unless they are named after a specific person or place. So, "humerus" would typically be written in lowercase, unless you are referring to the specific bone or using it in a title where capitalization is required.

The occipital condyles allow the head to turn side to side.

Synchrondoses, a form of cartilagous synarthrosis. Found between two ossifying centres of bone in development. Example, the epiphyseal growth plate between the epiphysis and diaphysis in developing long bones.

It all depends on how much energy is transferred to the brain, how big the crack is and where it is located.

It may lead to concussion injury

It may lead to Cerbrospinal fluid leak

Or the patient may not have any symptoms at all

If the patient has a depressed fracture along with the crack it may cause a mass effect on the brain.

Haematoma caused by the crack may cause mass effect on the brain.

It may also cause what is call panda eyes or racoon eyes due to ecchymosis and extravasation of blood underneath the skin.

human bones consist of smooth and rough cartilidge which allows for movement, a hard layer of compact bone gives it strength, inside the bone their are 2 types of marrow: yellow marrow-which stores fat cells and minerals, and red marow- where red blood cells are made. inside the compact bone their is also a layer of spongy bone- this is like honeycomb, it makes the bone strong without being too heavy

The condyle is a bony landmark defined as a smooth rounded knob. It is often found at the ends of long bones, such as the femur or mandible, and functions in articulating with other bones to allow movement at joints.

The right femur is typically larger and more robust than the left femur. The head of the femur also angles slightly inward on the right side. Additionally, the greater trochanter is located more laterally on the right femur compared to the left.

The weight of compact bone can vary depending on factors such as age, gender, and individual differences. On average, compact bone tissue comprises about 80% of the weight of the human skeleton. The weight of a compact bone can range from a few grams to several kilograms.

The manubrium or manubrium sterni is the upper part of the sternum. It articulates with the clavicles and first two ribs.

The long bone in the thigh is called the femur.

The brain does not have joints. Joints are primarily found in the skeletal system to facilitate movement between bones or cartilage. The brain is a soft, gelatinous organ that is protected by the skull and is not connected through joints like the rest of the body.

David Boreanaz portrays the character of Seeley Booth in the TV show "Bones." Booth is an FBI special agent who partners with forensic anthropologist Dr. Temperance Brennan to solve crimes.

A lumbar pillow is designed for the user's lower back to provide comfort and support. Usually, a lumbar pillow's purpose is to assist with posture while the user is sitting up. Lumbar pillows are more firm than head pillows and are usually made with memory foam or high resiliency foam.

The fibula is a long and slender bone located in the lower leg, beside the tibia. It is classified as a type of long bone. The fibula mainly serves as a support for the leg muscles and has a minor role in weight-bearing compared to the tibia.

Hyaline cartilage

actually it is articular cartilage that lines the end of long bones. depending on the age of the body and whether it is a fetus or child/adult. hyaline cartilage disappears around the 6th week old fetal development and is replaces with osseous tussue. there is a region, farther from the marrow cavity, that consists of typical hyaline cartilage that shows no sign of transformation into bone in the early years of growth. it is in the "zone of reserve cartilage"

The manubrium is the superior portion of the sternum and what articulates with the clavicles.
