Thyroid Gland Anatomy – Parts, Relations, Blood Supply, Venous Drainage, Lymphatic , Physiology The thyroid gland is a butterfly-shaped endocrine organ located in the neck, anterior to the trachea at the level of the 2nd to 4th tracheal rings, just below the larynx. It weighs about 25-30 grams in adults and consists of two lateral lobes connected by an isthmus, with a possible pyramidal lobe as a remnant of the thyroglossal duct. The thyroid is enclosed in a fibrous capsule and supplied by the superior and inferior thyroid arteries, and sometimes a thyroid ima artery. Venous drainage occurs through the superior, middle, and inferior thyroid veins. Lymphatic drainage involves the prelaryngeal, pretracheal, and paratracheal lymph nodes. Important relations include the recurrent and superior laryngeal nerves and the adjacent parathyroid glands. The thyroid secretes hormones essential for metabolism—thyroxine (T4) and triiodothyronine (T3)—from follicular cells, and calcitonin from parafollicular cells. #ThyroidGlandAnatomy #thyroid #anatomy #usmle #nclex #plab Join this channel to get access to perks:    / @learnmedicineasap   --------------------------------------------------------------------------------------------------------------------------------------------- Subscribe for more medical and health content:    / @learnmedicineasap   Check out our other helpful playlists Obstetrics and Gynecology    • Obstetrics and Gynecology   General Surgery Lessons    • General Surgery Lessons   Internal Medicine    • Internal Medicine   Child Health and Pediatrics    • Child Health and Pediatrics   Pharmacology Lecture Videos    • Pharmacology Lecture Videos   Anaesthesiology | Anesthesiology    • Anaesthesiology | Anesthesiology   Medical Parasitology    • Medical Parasitology   Infectious Diseases    • Infectious Diseases   Pathology    • Pathology   Microbiology    • Microbiology   Anatomy    • Anatomy   Ear Nose and Throat - ENT    • Ear Nose and Throat - ENT   Oral Health | Oral Hygiene | Dental Health    • Oral Health | Oral Hygiene | Dental Health   Ophthalmology | Eye Infections | Eye Diseases    • Ophthalmology | Eye Infections | Eye Diseases   Oncology    • Oncology   Sexually Transmitted Disease (STD) | Sexual Wellness & Health - Sexual Infection | STI    • Sexually Transmitted Disease (STD) | Sexua...   Women's Health    • Women's Health   Men's Health    • Men's Health   Vitamins, Minerals and their Deficiencies | Vitamin Deficiencies | Mineral Deficiencies    • Vitamins, Minerals and their Deficiencies ...   Clinical Skills | Clinical Techniques    • Clinical Skills | Clinical Techniques   Pharmacology Mnemonics    • Pharmacology Mnemonics   Internal Medicine Mnemonics    • Internal Medicine Mnemonics
