Definition
| Chylomicra and VLDL are responsible for taking the white fat and transporting it in the blood. For Chylomicra, it is in the intestines, for VLDL, it is in the liver. This process of transportation is induced by insulin. Once this fat is transported, it is broken down by HSL (hormone sensitive lipase) that is stimulated by norepinepherine. |

| metaphysis with epiphyseal plate. |
|
Definition
The metaphysis is the wider portion of a long bone adjacent to the epiphyseal plate.[1] It is this part of the bone that grows during childhood; as it grows, it ossifies near the diaphysis and the epiphyses. At roughly 18 to 25 years of age, the metaphysis stops growing altogether and completely ossifies into solid bone.
Epiphyseal plates ("growth plates") are located in the metaphysis[citation needed] and are responsible for growth in the length of the bone. |

Term
|
Definition
| When osteoblasts become trapped in the matrix they secrete, they become osteocytes. Osteocytes are networked to each other via long cytoplasmic extensions that occupy tiny canals called canaliculi, which are used for exchange of nutrients and waste through gap junctions. The space that an osteocyte occupies is called a lacuna (Latin for a pit). |

|
|
Term
|
Definition
| The cartilage model will grow in length by continuous cell division of chondrocytes, which is accompanied by further secretion of extracellular matrix. This is called interstitial growth. The process of appositional growth occurs when the cartilage model also grows in thickness due to the addition of more extracellular matrix on the peripheral cartilage surface, which is accompanied by new chondroblasts that develop from the perichondrium. |
