Skeletal System

The bones of the lower limb from superior to inferior are the femur (thigh bone), patella (kneecap), tibia and fibula (lower leg bones), tarsal bones (ankle bones), metatarsal bones (foot bones), and phalanges (toe bones).

In the skeletal system there are:

-ligaments

-tendons

-bones

-skull

-cartilage

Btw....Go to my youtube channel...it has awesome vids....my youtube: chykulay

Thanks <3

Bones also protect internal organs, store minerals like calcium and phosphorus for metabolic processes, and produce red and white blood cells in the bone marrow.

a type of bone fracture producing many bone fragments is?

Bones are living. Think of it this way, if bones weren't "alive", they wouldn't be able to heal if broken.

They are made up of cells that heal the wound, the bone is really just a hard shell that keeps you upright and a home for all those cells.

The enlarged portion of the thoracic duct is called the cisterna chyli, which serves as a storage area for lymphatic fluid before it is returned to the bloodstream. It is located near the aorta and the diaphragm at the level of the second lumbar vertebra.

Long bones of the body, such as the femur, have an epiphyseal cartilage, a plate of cartilage that separates the epiphysis from the diaphysis as long as the bone is still growing lengthwise. An x-ray would indicate whether the epiphyseal cartilage is still present. The clinicians check if the cartilage is still there and if it is, growth is still occurring; if it is not, the bone has reached its adult length.

False. While many skeletal muscles do work in antagonistic pairs (e.g. biceps and triceps), not all skeletal muscles function this way. Some skeletal muscles work alone or in synergy with other muscles to produce movement.

Sesamoid bones are small ossified nodes embedded in the tendons to provide extra leverage and reduce pressure on the underlying tissue. Many exist around the palm at the bases of the digits; the exact number varies between different people.

Interstitial bone growth in long bones occurs in the epiphyseal plate, or growth plate, located at the ends of long bones. Here, cartilage cells (chondrocytes) proliferate, differentiate, hypertrophy, and are replaced by bone tissue, leading to longitudinal bone growth. This process is crucial for growth and development in children and adolescents.

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.

Petrous (under the sphenoid when viewing the external base of the skull)

Squamous region (big smoothe plate when viewing lateral surface of skull)

Styloid Process (little pokey thing)

Mastiod process (larger bumb just behind it)

zygomatic processe (conects to the zygomatic bone)

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.
