What is the depostion of minerals within the cartilage?
Ossification
Intramembranous ossification begins with what cells?
Intramembranous ossification begins when osteoblasts differentiate within a mesenchymal or fibrous connective tissue.
Do tendon sheaths act as a friction-reducing structures?
Yes, tendon sheaths do act as friction reducing structures within the body. Tendon sheaths generally are found in areas where the tendons are constantly under pressure do to motion.
Do tendons bleed?
Tendons themselves do not have a direct blood supply. However, they are surrounded by blood vessels that can bleed if there is an injury to the surrounding tissues, such as a tendon tear or rupture. In those cases, bleeding can occur around the tendon, but not within the tendon itself.
What type of bone is usually found in a tendon?
Sesamoid bones grow within tendons. An example of a sesamoid bone is the patella (kneecap).

When osteoblasts begin to differentiate within a connective tissue the process is called?
Intramembranous Ossification
Where are sensory stretch receptors of the withdrawal reflex located?
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.
Sesamoid bones are bones embedded within a tendon What if your largest sesamoid bone anchors the tendon of the quadriceps femoris muscle What is it?
Patella
What is a Sesamoid?
A bone formed in a tendon. Example are the patella and baculumA sesamoid bone is that bone which is embedded within a tendon. An example is the patella.
What is the process when bone forms directly within mesenchyme arranged in sheetlike layers that resemble membranes?
Intramembranous ossification process
Do tendon sheaths act as a friction-reducing structures?
Yes, tendon sheaths do act as friction reducing structures within the body. Tendon sheaths generally are found in areas where the tendons are constantly under pressure do to motion.
What bones is produced by intramembranous ossification?
Ossification means bone growth or formation. I will be disscussing breifly normal or physiological ossification because there is pathological ossification.There are two types of ossification in the human body: endochondral and intramembranous. Most of the bones in the human skeleton , especially the long and short bones, develop via endochondrial ossification, but some including the clavicle and most of the bones of the skull( flat bones) are formed by the intramembranous type. Intramembranous ossification , the source of most of the flat bones, is so called because it takes place within condensations of mesenchymal tissue and not by replacement of pre-existing piece of hyaline cartilage as the case in endochondral ossification. The frontal and parietal bones of the skull, as well as parts of the temporal and occipital bones and the mandible and maxilla, are formed by intra membranous ossification. This process also contributes to the growth of short bones and the thickening (not the lengthening) of long bones.
Do tendons bleed?

Bone located within the quadriceps tendon?
Myositis ossifcans - Very rare or more commonly, the patella (kneecap)
What kind of bone is the patella?
The patella, also known as the kneecap, is a sesamoid bone. Sesamoid bones are bones that are embedded within tendons and provide protection and mechanical advantage to that tendon. The patella is located within the quadriceps tendon and acts as a fulcrum to increase the leverage of the quadriceps muscles during knee extension.
