Thyroid gland: [TA] an endocrine (ductless) gland consisting of irregularly spheroid follicles, lying in front and to the sides of the upper part of the trachea and lower part of the larynx and of horseshoe shape, with two lateral lobes connected by a narrow central portion, the isthmus; and occasionally an elongated offshoot, the pyramidal lobe, which passes upward from the isthmus in front of the larynx. It is supplied by branches from the external carotid and subclavian arteries, and its nerves are derived from the middle cervical and cervicothoracic ganglia of the sympathetic system. It secretes thyroid hormone and calcitonin. SYN: glandula thyroidea [TA], thyroid body, thyroidea.

Thyroid gland: A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.

These medical condition or symptom topics may be relevant to medical information for Thyroid gland:
Thyroid gland (organ): Hormone gland in the neck around the trachea.
Thyroid gland (organ): The thyroid is a small gland in the neck that takes up iodine from the body to produce hormones that help control the body's metabolism, and regulate how quickly the body should work and use energy. (Source: excerpt from Thyroid Disease: NWHIC)
The thyroid is a gland in the neck. It has two kinds of cells that make hormones . Follicular cells make thyroid hormone , which affects heart rate, body temperature, and energy level. C cells make calcitonin , a hormone that helps control the level of calcium in the blood.
The thyroid is shaped like a butterfly and lies at the front of the neck, beneath the voice box (larynx ). It has two parts, or lobes . The two lobes are separated by a thin section called the isthmus .
A healthy thyroid is a little larger than a quarter. It usually cannot be felt through the skin. A swollen lobe might look or feel like a lump in the front of the neck. A swollen thyroid is called a goiter . Most goiters are caused by not enough iodine in the diet. Iodine is a substance found in shellfish and iodized salt.
