Thyroid Gland Anatomy In the neck, the thyroid gland is surrounded by a number of other important anatomical structures. Anteriorly (towards the front of the thyroid gland), the gland is covered by muscles of the neck, called the sternohyoid and the sternothyroid muscles.The thyroid gland itself is covered by a capsule made of connective tissue.he carotid sheaths are posterior relations of both the left and the right lobes of the thyroid gland. Further posterior to the carotid sheaths are the vertebrae of the neck, and other nerves, arteries and veins. There are also muscles of the neck, such as the scalene muscles sitting behind the thyroid gland.

- The posterior chain is simply the backside of your body and its primary muscles include the lower back, gluteus maximus (glutes), hamstrings, and calves. This area is often neglected and misunderstood.There are two main reasons why. The first reason is many people sit 8-10+ hours per day.lthough the posterior chain consists of the low back, glutes, hamstrings and calves, the focus here will be on the function and importance of the glutes. When the glutes become inhibited the posterior chain is not functioning properly.

Cricothyroidotomy Fascia and Ligament. The thyroid gland is ensheathed by the visceral fascia, a division of the middle layer of deep cervical fascia, which attaches it firmly to the laryngoskeleton. The anterior suspensory ligament extends from the superior-medial aspect of each thyroid lobe to the cricoid and thyroid cartilage.The posteromedial aspect of the gland is attached to the side of the cricoid cartilage, first and second tracheal ring, by the posterior suspensory ligament (ie, Berry ligament).he anterior suspensory ligament extends from the superior-medial aspect of each thyroid lobe to the cricoid and thyroid cartilage.

Thyroid Thyroid Disorders. The thyroid gland, located in the anterior neck just below the cricoid cartilage, consists of 2 lobes connected by an isthmus. Follicular cells in the gland produce the 2 main thyroid hormones, tetraiodothyronine (thyroxine, T 4) and triiodothyronine (T 3).

- Functional Anatomy of the Thyroid and Parathyroid Glands. Thyroid glands are located in the neck, in close approximation to the first part of the trachea. In humans, the thyroid gland has a butterfly shape, with two lateral lobes that are connected by a narrow section called the isthmus.he structure of a parathyroid gland is distinctly different from a thyroid gland. The cells that synthesize and secrete parathyroid hormone are arranged in rather dense cords or nests around abundant capillaries.

The Posterior Triangle of the Neck Subdivisions. The omohyoid muscle splits the posterior triangle of the neck into two; a superior and inferior part. The superior part is larger, and is called the occipital triangle. The occipital triangle is crossed by the accessory nerve. The inferior triangle is known as the subclavian triangle.he omohyoid muscle splits the posterior triangle of the neck into two; a superior and inferior part.

Endocrine Systems Oats & Thyroid Problems. The thyroid, a butterfly-shaped endocrine gland located in the front of the neck near the trachea, regulates hormones, metabolism and protein production. Thyroxine (abbreviated as T3) and triiodothyronine (T4), hormones secreted by the thyroid, travel to other parts of the body.

Overview 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. 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...

Lobes of The Thyroid Gland The thyroid gland consists of right and left lobes anterior and lateral to the larynx (voice box) and trachea (windpipe). Each lobe is pear shaped, with its apex directed upward to the level of the oblique line of the thyroid cartilage and its base lying below at the level of the fourth or fifth tracheal ring.elation of The Thyroid Gland. The thyroid gland lies in front of the neck, hidden by the anterior muscles of the neck, sternothyroid and sternohyoid muscles. It usually weighs 25g but this varies, as the gland is slightly heavier in females, and enlarges during menstruation and pregnancy.

Chronic Thyroiditis (Hashimoto's Disease)  In-Depth Report In-Depth From A.D.A.M. Background. The thyroid is a small, butterfly-shaped gland located in the front of the neck that produces hormones, notably thyroxine (T4) and triiodothyronine (T3), which stimulate vital processes in every part of the body.

- Tibialis posterior. The tibialis posterior muscle is a relatively small muscle located within the back side of the calf. It is also the most centrally located muscle in the leg, arising from the inner borders of the fibula and tibia on the posterior (rear) side.he primary function of this muscle is to provide stability to the lower leg. It also facilitates foot inversion (swiveling inward) and aids the ankle's plantar flexion (flexing the foot or toes downward). Additionally, the muscle performs a key role in providing support to the foot's medial arch.

Superior thyroid artery 1 This artery branches from the superior thyroid artery near its bifurcation from the external carotid artery. 2  It pierces the hyothyroid membrane, and supplies the muscles, mucous membrane, and glands of the larynx, connecting with the branch from the opposite side. The superior laryngeal artery accompanies the internal laryngeal branch of the superior laryngeal nerve, beneath the thyrohyoid muscle. 2  This artery branches from the superior thyroid artery near its bifurcation from the external carotid artery.

There is an anterior scalene (scalenus anterior), a medial scalene (scalenus medius), and a posterior scalene (scalenus posterior).

Your Thyroid Gland The thyroid gland is the biggest gland in the neck. It is situated in the anterior (front) neck below the skin and muscle layers. The thyroid gland takes the shape of a butterfly with the two wings being represented by the left and right thyroid lobes which wrap around the trachea.The sole function of the thyroid is to make thyroid hormone.

Muscles and Walls of the Pharynx The palatopharyngeus muscle starts at the posterior border of the hard palate on the palatine aponeurosis and finishes on the posterior aspect of the lamina of the thyroid cartilage of the larynx, as do the other paired muscles. It elevates the pharynx in order to close off the nasopharynx during swallowing.

Difference Between Thyroid and Parathyroid Thyroid. The thyroid gland, which is situated at the front of the neck just below the laryngeal prominence (Adam’s apple), is a single gland with two lobes and a central, connecting isthmus arranged like a butterfly. It has two vessels supplying blood, the superior and the inferior thyroid vessels.

- The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroid’s job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormone helps the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as they should (Figure 1).

- Embryologically, the thyroid descends from the foramen cecum in the posterior aspect of the tongue to its usual (orthotopic) position anterior to the upper tracheal rings. Embryologically, by week 4 of intrauterine life, precursors of nasal cavities and the lenses of the eyes are formed.

Thyroid Gland Location, Anatomy, Parts and Pictures Location of the Thyroid Gland. The thyroid gland is located at the levels of C5 to T1 vertebrae lying immediately below the larynx, with the two lobes on each side of and anterior to the trachea. It starts just below the Adam’s apple (thyroid cartilage), about the same level as the cricoid cartilage.rteries of the Thyroid Gland. The thyroid gland is one of the most highly vascularized glands in the body. The thyroid arteries can be divided into superior and inferior thyroid arteries on each side (left and right). The superior thyroid arteries arise from the external carotid arteries.
