What type of synovial joint is the elbow?

During anaerobic respiration, some living systems use an organic molecule as the final electron acceptor. Processes that use an organic molecule to regenerate NAD+ from NADH are collectively referred to as fermentation. One type of fermentation is lactic acid fermentation, which produces lactic acid (lactate) and NAD+1. The accumulation of lactic acid can lead to a burning sensation in muscles during intense exercise.

The malleus, incus, and stapes are three small bones, collectively known as the ossicles, located in the middle ear. These bones work together to transmit sound waves from the eardrum to the inner ear, where they are converted into nerve impulses that are then sent to the brain. The malleus is attached to the eardrum, the incus is in between the malleus and the stapes, and the stapes is connected to the inner ear. Together, they form a chain that amplifies the sound waves and transmits them efficiently to the inner ear.

The urinary bladder and internal reproductive organs, including the uterus, ovaries, and testes, are in the pelvic cavity. The pelvic cavity is a bony structure formed by the pelvis and contains the terminal portions of the digestive tract, urinary tract, and reproductive tract. It is situated inferior to the abdominal cavity and is separated from it by the pelvic brim, which is a rim of bone formed by the iliac crests, sacrum, and pubic bones. The pelvic cavity is bounded by the pelvic bones and the pelvic diaphragm and is lined with pelvic peritoneum.

Hematoma formation occurs immediately after the bone is fractured. The blood vessels that have been damaged due to the fracture bleed and form a hematoma or a blood clot.

Next, callus formation begins, which involves the accumulation of fibrous tissue, cartilage, and new bone cells around the fracture site, forming a soft callus.

The soft callus then undergoes callus ossification, in which the fibrous tissue and cartilage are gradually replaced by hardened new bone tissue.

Finally, bone remodeling occurs, which involves the reshaping of the newly formed bone tissue to match the shape of the original bone, and the removal of any excess bone material.

Therefore, option b, hematoma formation, Callus formation, Callus ossification, Bone remodeling, is the correct sequence of repair as a fractured bone goes through the healing process.
