  2. Thyroid - Wikipedia

    en.wikipedia.org/wiki/Thyroid

    Small accessory thyroid glands may in fact occur anywhere along the thyroglossal duct, from the foramen cecum of the tongue to the position of the thyroid in the adult. [4] A small horn at the back of the thyroid lobes, usually close to the recurrent laryngeal nerve and the inferior thyroid artery, is called Zuckerkandl's tubercle. [9] Other ...

  3. Thyroid nodule - Wikipedia

    en.wikipedia.org/wiki/Thyroid_nodule

    Thyroid nodules are nodules (raised areas of tissue or fluid) which commonly arise within an otherwise normal thyroid gland. [1] They may be hyperplastic or tumorous, but only a small percentage of thyroid tumors are malignant. Small, asymptomatic nodules are common, and often go unnoticed. [2]

  4. Parathyroid gland - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_gland

    The parathyroid glands are variable in number: three or more small glands, [5] and can usually be located on the posterior surface of the thyroid gland. [5] Occasionally, some individuals may have six, eight, or even more parathyroid glands. [3] Rarely, the parathyroid glands may be within the thyroid gland itself, the chest, or even the thymus ...

  5. Computed tomography of the thyroid - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography_of_the...

    Although the correlation between thyroid nodule size and malignancy risk is limited, nodule size affects prognosis in malignant nodules. Small thyroid cancers (less than 2 cm) tend to have an indolent course, with favourable prognosis even if not treated. Less than 7% of the imaging-detected ITNs are seen in younger populations.

  6. Thyroid follicular cell - Wikipedia

    en.wikipedia.org/wiki/Thyroid_follicular_cell

    Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen .

  7. Colloid nodule - Wikipedia

    en.wikipedia.org/wiki/Colloid_nodule

    Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]

  8. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    Thyroid disease is a medical condition that affects the function of the thyroid gland. The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ. These hormones normally act in the body to regulate energy use ...

  9. Parafollicular cell - Wikipedia

    en.wikipedia.org/wiki/Parafollicular_cell

    Parafollicular cells, also called C cells, are neuroendocrine cells in the thyroid. They are called C cells because the primary function of these cells is to secrete calcitonin. [1] They are located adjacent to the thyroid follicles and reside in the connective tissue. These cells are large and have a pale stain compared with the follicular cells.
