| Name: | thymus |
|---|---|
| Synonyms: | |
| Definition: | Paired organ where maturation of T-lymphocytes occurs. The adult thymus located on the dorsomedial aspect of the branchial cavity above the third pharyngeal cartilage. The thymus undergoes a period of rapid growth beginning at about the third week and continuing for several more weeks. Accompanying this growth is a dramatic change in the shape of the thymus. It is ovoid initially and then starts to grow dorsally along the skull, forming a characteristic protrusion. During this growth period the adult pattern of rag1-positive cortex and rag1-negative medulla becomes established. The protrusions diminish with age and the thymus gradually shrinks; at two years, the thymus is again confined to the pharynx with minimal if any protrusion. |

| Name: | fat cell |
|---|---|
| Synonyms: | adipocyte, lipocyte, lipocytes |
| Definition: | A fat-storing cell found mostly in the abdominal cavity and subcutaneous tissue of mammals. Fat is usually stored in the form of triglycerides. Cell that stores fat in a unilocular lipid droplet, has a thin circular cytoplasm and pericentral nucleus. The average adult adipocyte diameter is between 30 and 40 micrometers. No adipocytes were observed in larvae on 6 or 9 dpf. |
