| 영문 | parotid gland | 한글 | 귀밑샘, 이하선 |
|---|---|---|---|
| 설명 | 침샘의 하나. 침샘이란, 음식을 삼킬 때 입안으로 분비되어 음식물이 잘게 씹히는데 도움을 주며, 음식물을 소화하는데 이용되는 효소를 가지고 있는 침을 생산하는 곳을 말함. 크게 3가지의 침샘을 가지고 있으며, 위치와 모양은 옆의 그림과 같다.  |

| 영문 | endocrine gland | 한글 | 내분비샘 |
|---|---|---|---|
| 설명 | 신체의 내부로 분비가 되어서 다른 세포의 기능이나 활성의 변화를 일으키는 물질인 호르몬을 분비하는 곳을 이르는 말이다. 대표적인 내분비샘은 갑상샘, 부갑상샘, 부신, 이자, 뇌하수체, 난소, 고환, 솔방울샘, 가슴샘 등이다. 마지막에 나오는 2개의 기관은 내분비 기능을 하는 것으로 생각이 되지만 확실히 그것이 무슨 기능을 하는 지에 대해선 아직까지 정확하게 밝혀지지 않고 있다.  |

|---|---|---|---|
| 설명 | 콩팥위에 존재하는 피라밋모양의 구조물. 겉질과 속질로 되어 있으며 호르몬의 분비가 주역할이다.  |

| 영문 | gland | 한글 | 샘 |
|---|---|---|---|
| 설명 | 자신의 대상에 필요가 없는 물질을 만들어 분비하는 세포가 모여서 만드는 구조. 즉 분비물을 제조하는 세포가 모인 것이다. 선에는 내분비샘과 외분비샘의 2가지가 있다. 내분비샘이란 몸밖이 아닌 내부, 즉 직접 혈중으로 분비물을 분비하는 샘으로 이 때에 분비되는 물질을 호르몬이라고 한다. 이것은 주로 몸안의 다른 세포에 작용을 하여 그 세포의 대사, 분열 등의 변화를 초래하고 몸의 환경의 변화에 따른 적응을 돕는 역할을 한다. 외분비샘이란 몸밖으로 관구조를 통하여 분비물을 내보내는 샘을 말한다. |

| 영문 | pineal gland | 한글 | 솔방울샘, 송과선 |
|---|---|---|---|
| 설명 | 뇌의 중앙선부위의 등쪽에 존재하는 내분비기관이다. 솔방울샘은 melatonin을 분비한다. 동물에서는 성분화발달에 기여하는 것으로 되어 있으나, 사람에서는 그 기능이 아직 명확치 않다. |

| thymus | <anatomy> The lymphoid organ in which T lymphocytes are educated, mature and multiply. It is composed of stroma (thymic epithelium) and lymphocytes, almost entirely of the T-cell lineage. In mammals the thymus is just anterior to the heart within the rib cage, in other vertebrates in rather undefined regions of the neck or within the gill chamber in teleost fish. The thymus regresses as the animal matures. (18 Nov 1997) |

| thymus and parathyroids, hypoplasia of | See third and fourth pharyngeal pouch syndrome. (12 Dec 1998) |
| thymus-dependent zone | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
| thymus derived lymphocyte | <haematology, immunology> A class of lymphocytes, so called because they are derived from the thymus and have been through thymic processing. Involved primarily in controlling cell-mediated immune reactions and in the control of B-cell development. The T-cells coordinate the immune system by secreting lymphokine hormones. There are 3 fundamentally different types of t cells : helper, killer, and suppressor. Each has many subdivisions. T-cells are also called t lymphocytes. They bear T-cell antigen receptors (CD3) and lack Fc or C3b receptors. Major T-cell subsets are CD4 (mainly helper cells) and CD8 (mostly cytotoxic or suppressor T-cells). Uncontrolled proliferation of this type of cell gives rise to T-cell leukaemia/lymphoma. (21 Jun 1999) |
| thymus extracts | Extracts of the thymus that contain specific, but uncharacterised factors or proteins with specific activities; three distinct substances are already known: thymotoxin, thymin and thymosin. (12 Dec 1998) |
| thymus hormones | Humoral factors secreted by the thymus gland. They participate in the development of the lymphoid system and the maturation of the cellular immune response. (12 Dec 1998) |
| thymus hyperplasia | Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (12 Dec 1998) |
| thymus-independent antigen | An antigen that does not require T helper cell activation in order for the host's B-cells to be stimulated. Repeating polymers such as polysaccharides are examples of T-independent antigens. (05 Mar 2000) |
| thymus treatment | Treatment of disease by administration of extracts of thymus gland. (05 Mar 2000) |
| triceps muscle of calf | <anatomy> The two bellies of the gastrocnemius and soleus considered as one muscle. Synonym: musculus triceps surae, triceps muscle of calf. (05 Mar 2000) |
| foetal calf serum | <cell culture> The serum originating from embryonic calves and an expensive component of standard culture media for many types of animal tissue cells. It is used as an important part of growth media for promoting the growth of tissue cultures. It provides a source of growth hormones and other growth factors. (11 Nov 1997) |
| football calf | An obsolete term used to describe the doughy sensation elicited on palpation of the calf when muscle necrosis has developed as a consequence of acute ischemia produced by acute arterial embolism. (05 Mar 2000) |
| lateral cutaneous nerve of calf | <anatomy, nerve> It arises from the common peroneal in the popliteal space and is distributed to the skin of the inferolateral surface of the calf. Synonym: nervus cutaneus surae lateralis, lateral cutaneous nerve of calf. (05 Mar 2000) |
| lobules of thymus | Areas of thymic tissue 0.5 to 2 mm in diameter with a cortex and medulla. Synonym: lobuli thymi. (05 Mar 2000) |
