Anatomy Of Thyroid

The thyroid is a butterfly shaped gland that sits low on the front of the neck. The thyroid gland is a butterfly shaped vascular red brown endocrine gland situated in the midline of the anterior neck.

Thyroid Gland Overview The Thyroid Gland Is A Major Player

The thyroid has two side lobes connected.

Anatomy of thyroid. Tri iodothyroninet3 and thyroxine t4. Thyroid hormones regulate the basal metabolic rate and are important in the regulation of growth of tissues particularly nervous tissue. Thyroid glands are brownish red in color.

The gland varies from. Most animals however have two separate glands on either side of the trachea. Two types of hormones are produced which are the iodine containing hormones.

The follicles are made up of a central cavity filled with a sticky fluid called colloid. 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. On average the gland weighs between 15 to 25 g and is the largest of the endocrine glands.

The thyroid gland lies in the neck in front of the upper part of the trachea. 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. Calcitonin plays a role in calcium homeostasis.

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. The gland may enlarge in some normal conditions like menstruation and pregnancy. Under normal circumstances it extends from the level of the 5th cervical vertebra c5 to the first thoracic vertebra t1.

The thyroid gland or simply the thyroid is an endocrine gland in the neck consisting of two lobes connected by an isthmus. In humans the thyroid gland has a butterfly shape with two lateral lobes that are connected by a narrow section called the isthmus. The tissue of the thyroid gland is composed mostly of thyroid follicles.

Surrounded by a wall of epithelial follicle cells the colloid is the center of thyroid hormone production and that production is dependent on the hormones essential and unique component. The infrahyoid muscles strap muscles are the sternohyoid sternothyroid thyrohyoid and omohyoid. It is found at the front of the neck below the adams apple.

Your thyroid lies below your adams apple along the front of the windpipe. Of the neck muscles the thyroid is covered anteriorly by the strap or infrahyoid muscles and by the sternocleido mastoid muscles.
