Thyroid Anatomy

Anatomy of the thyroid gland the thyroid arises from a downward outpouching of the floor of the pharynx and a persisting remnant of this migration is known as a thyroglossal duct. A probe is placed on the skin of the neck and reflected sound waves can detect abnormal areas of thyroid tissue.

Thyroid anatomy. The thyroid is butterfly or h shaped and is composed of two lobes each with a superior and inferior pole connected by an isthmus. Posteromedially the gland is attached by the lateral thyroid ligaments to the cricoid cartilage. The thyroid is a highly vascular brownish red gland located anteriorly in the lower neck extending from the level of the fifth cervical vertebra down to the first thoracic.

Each lobe measures approximately 4 cm in length. The gland varies from an h to a u shape and is formed by 2 elongated lateral lobes with superior and inferior poles connected by a median isthmus with an average height. The thyroid gland or simply the thyroid is an endocrine gland in the neck consisting of two lobes connected by an isthmus.

A small amount of radioactive iodine is given. Tri iodothyroninet3 and thyroxine t4. The thyroid gland also secretes a hormone called calcitonin that is produced by the parafollicular cells also called c cells that stud the tissue between distinct follicles.

Thyroid position in the neck in front of the trachea windpipethe thyroid is a gland that sits across the windpipe like a bow tie just below the adams apple. It has a shape a bit like a butterfly with the thyroid lobes forming the wings and the isthmus the body of the butterfly fig. Calcitonin is released in response to a rise in blood calcium levels.

Thyroid hormones regulate the basal metabolic rate and are important in the regulation of growth of tissues particularly nervous tissue. It is found at the front of the neck below the adams apple. The thyroid gland is located in the anterior neck spanning between the c5 and t1 vertebrae.

It is said to have a butterfly shape. It is an endocrine gland divided into two lobes which are connected by an isthmus. Two types of hormones are produced which are the iodine containing hormones.

The parathyroid glands lie posteromedially and are sometimes intracapsular. The thyroid gland lies in the neck in front of the upper part of the trachea. Calcitonin plays a role in calcium homeostasis.

Additionally the levator glandulae thyroideae levator of the thyroid gland which is a fibromuscular structure also anchors the isthmus or pyramidal lobe to the hyoid bone. The gland itself consists of two oblong lobes lying on either side of the trachea windpipe and connected by a narrow band of tissue called the isthmus.
