Skeletal System

It depends how hard you pound. The harder you pound, the fewer times you have to do it before the femur breaks. And it also depends on how strong the femur is, and what area you spread the pound over. Different peoples femurs have different strengths.

No, bones in the foot are connected by ligaments and tendons, so they should not float freely. However, a broken bone or dislocated joint in the foot may give the sensation of a floating bone. It is important to seek medical attention if you suspect any issues with the bones in your foot.

Yes, the number of ribs is slightly variable and is not related to gender - some men have a "missing" rib while some women have an "extra" rib. The creation story listed in Genesis is not supported by human anatomy.

The tibia is not a part of the coxal bone. The coxal bone is also known as the hip bone and is made up of three fused bones: ilium, ischium, and pubis. The tibia is a separate bone located in the lower leg.

Your brain would be very unprotected, and your eyes, nose, face muscles and skin would look horribly deranged. The skull protects your brain and serves as a base for your face (no pun intended).

If humans had no bones, they would have no structural support for the body, making movement and vital functions extremely difficult. Additionally, the lack of bones would leave vital organs vulnerable to injuries. Overall, it would be impossible for humans to survive without the support and protection that bones provide.

Her name is Emily Deschanel, and her sister, Zooey Deschanel guest stars in one of the christmas episodes as her second cousin. booth is played by David Boreanaz, angela by Michella Conlin, hodgins by TJ Thyne, cam by Tamara Taylor, and sweets by John Francis Daley. love tha showw :)))

Lower most two pairs of ribs (11th and 12th) are known as floating ribs because they are only attached to vertebrae but not to the sternum.

Postmenopausal women can build bone density, it is just harder than it was for them before menopause.

Exercises with weights or resistance can help to increase bone mineral deposition and should be part of any woman's routine.

A diet that is high in calcium, vitamin D, and phosphorus can help with bone density since those are the building blocks of bone. It is important to remember that vitamin D is also made in the skin when it is exposed to sunlight so it is important to get out in the sun. Though dietary vitamin D and vitamin D from sun exposure are different forms, there is some controversy as to if they work equally in the body. To be safe, make sure get adequate amounts of both.

There are a class of drugs you can get from your doctor called bisphosphonates that help to prevent bone loss due to osteoporosis. Bisphosphonates work by reducing the amount of bone destruction and though they don't increase bone density on their own, they decrease the loss and along with the other measures can help to increase overall bone density.

Another medication you may want to discuss with your doctor is hormone replacement therapy. Hormone replacement therapy can help to decrease the bone loss due to menopause but it does carry some risks. The amount of these risks depends on the particular woman and needs to be evaluated with her and her doctor.

The zygomatic bone is not part of the orbit of the skull. The orbit is made up of several bones including the frontal, ethmoid, lacrimal, sphenoid, maxilla, palatine, and zygomatic bones.

The strength of a bone is derived from the combination of both the periosteum, which is the outer dense connective tissue membrane covering the bone, and the spongy bone, which is a lattice-like structure found inside the bone. The periosteum provides protection and support, while the spongy bone helps to absorb impact and distribute forces across the bone.

The skeletal system has one main function: to act a levers for the muscles to perform movement. The also are a storage spot for fat (yellow marrow) and blood cell production (red, white cells plus platelets) and it gives protection for many vital organs such as the brain, heart and lungs.

No the tendons are part of the connective tissue

Sort of...

Assuming there is no GVHD and the bone marrow transplant is successful, a blood test will show what percent of the recipient's blood is their own blood and what percent of the recipient's blood was produced from the donor's bone marrow. If the test comes back ">95%", then the recipient's blood and the donor's blood have become DNA-identical.

Interestingly enough, the recipient's hair and saliva remain the same DNA they were born with. Their hair and saliva do NOT change to the donor's DNA. So, the recipient of the bone marrow transplant would then have two DNA's in their body.

Neat stuff!

The red bone marrow makes red blood cells. The yellow bone marrow makes chemical energy.

A blue bottle has an exoskeleton, which is a hard outer covering that provides protection and support for the animal's body. This exoskeleton is typically made of chitin, a tough biological material.

Yes, pugs, like all mammals, have three bones in the middle ear called the ossicles. These bones are the malleus, incus, and stapes, and they play a crucial role in transmitting sound vibrations from the eardrum to the inner ear for hearing.

The knee has a number of functions

1) Supports body in upright position without muscles having to work

2) Helps in lowering and raising body eg sitting, climbing and squatting

3) Allows rotation/twisting of leg to place and position foot

4) Makes walking more efficient

5) Acts with ankle joint as a strong forward propeller of the body

6) Provides stability of the leg

7) Acts as a shock absorber

Healthy adult bone marrow contains yellow fat cells, connective tissue, and red marrow that produces blood. The bone marrow of a healthy infant is primarily red due to active production of red cells necessary for growth.

The ACL (anterior cruciate ligament) and the PCL (posterior cruciate ligament) are the two major ligaments in the knee that work together to provide stability in the knee. They cross each other and form an 'X' which allows the knee to flex and extend without side to side movement.

These are the four stages:

1) nonunion with no epiphyses

2) nonunion with separate epiphyses

3) partial union, and

4) complete union

. The results provide broader age ranges for the stages of union than previous studies. Age ranges for males and females are similar or vary by only 1-2 years. .

The patella is prevented from excessive lateral displacement due to the alignment of the patellar ligaments, particularly the medial patellofemoral ligament (MPFL). Additionally, the trochlear groove of the femur provides a bony structure that helps guide the patella during movement, limiting its lateral movement. Strong muscles around the knee joint, such as the quadriceps and vastus medialis, also play a role in stabilizing the patella and preventing lateral displacement.

In infants, the coxal bone consists of three separate bones: the ilium, the ischium, and the pubis. These three bones fuse together to form the single coxal bone in adults.
