Skeletal System

The bony prominence on the anterior surface of the leg just below the knee is most likely the tibial tuberosity. It serves as the attachment point for the patellar ligament, which connects the patella (kneecap) to the tibia. This area can be sensitive to touch and may become inflamed with activities that stress the knee, such as running or jumping.

The ICD-9 code for bone marrow fibrosis is 289.81.

That part is called a ligament. Ligaments are fibrous tissue that connect bones to each other at a joint and help to stabilize and support the joint during movement.

The time it takes for broken bones to heal varies depending on the severity of the break and individual factors. Generally, small bones may take about 4-6 weeks to heal, while larger bones could take several months. It's important to follow your doctor's recommendations for proper healing.

The cup-shaped depression on the hip joint that receives the head of the femur is called the acetabulum. It forms part of the hip bone structure known as the pelvis and allows for the articulation and movement of the femur within the hip joint. The acetabulum provides stability and support for the hip joint during weight-bearing activities.

A 'leg' officer is a slightly contemptous word used by qualified airborne troops to describe a regular infantry soldier... since they have to leg it everywhere...

thus the skippy's list joke, an appropriate greeting for a leg officer is not, "Airborne leads the wa.. oh sorry sir..."

There are 6 types of freely moving joints: ball-and-socket, hinge, glide, pivot, ellipsoidal, and saddle.

If you want to make each one:

ball-and-socket: Joystick on a game controller

hinge: door hinge

glide: 2 blocks, or dominoes, put together face to face and held by 2 rubber bands, one lengthwise and the other crosswise

pivot: the mechanism inside a dead bolt lock works by pivoting when you lock and unlock it

ellipsoidal: like the joystick, only the movement is smaller

saddle: toy saddle with a toy human model sitting in it and move it in all directions except a pivot.

The patella bone is classified as a sesamoid bone, which is a type of irregular bone. Sesamoid bones form within tendons where there is high friction and stress, such as the patella within the quadriceps tendon.

One possible explanation for this sensation could be a condition known as "swimmer's toe," which involves inflammation and pain in the toes due to repetitive kicking while swimming. It is not a dislocation of the bones, but rather irritation of the soft tissues in the toes. However, it is best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Snakes do not have any bones; instead, their skeletal system is made up of hundreds of vertebrae, which provides them with flexibility and allows them to swallow large prey items whole.

Yes, during periods of intense exercise when oxygen supply is limited, skeletal muscle can produce lactic acid through anaerobic metabolism. This can lead to muscle fatigue and soreness.

The spine is composed of 24 different bones called vertebrae, 7 in your neck, 12 in your upper to mid back, and 5 in your low back.  The upper to mid back vertebrae are called thoracic vertebrae, and they are referred to as T1-T12 from top to bottom.  T3 & T4 are then the 3rd and 4th thoracic vertebrae from the top.  They are located right between your shoulder blades (called scapulae)!  

In an automotive engine, the wrist pin connects the piston to the connecting rod. It allows the piston to move up and down while the connecting rod transfers this motion to the crankshaft. This connection is crucial for proper engine operation and performance.

Bone marrow is a spongy tissue found in the center of bones, such as the hip and thigh bones. It is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Bone marrow plays a crucial role in maintaining a healthy immune system.

The capillary tube is the hollow opening inside the thermometer that the liquid rises or lowers in so that you can read the temperature. The bulb is the bottom portion that holds the liquid and the part you use for contact to get a temperature reading.

There are 33 bones in the spinal column. There are five regions in the column. In descending order there is the Cervical region which has 7 bone, Thoracic region which has 12 bones, Lumbar region which has 5 bones, Sacral region which has 5 bones (these bones are fused together), and the Coccygeal region that has 4 bones (these bones are fused together). The coccygeal region can actually have anywhere from 3-5 bones, but the average is 4.

The femur fits into the acetabulum at its proximal end.

A bone that is curved, thin, and flat is likely a flat bone. Flat bones, such as the ribs or certain skull bones, provide protection for internal organs and have a broad surface area for muscle attachment.

The cervical enlargement contains nerves that supply the upper limbs, shoulders, and neck muscles. It is responsible for coordinating motor function in this area of the body.

The spinous process of the 7th cervical vertebra (C7) is typically the longest and most prominent in the living person. It can often be easily palpated at the base of the neck where it forms a bony prominence known as the vertebra prominens.
