1Architectural Layers of the Deep Neck & The Thymus Gland

4 Micro-Bites
Boundaries and the Three Deep Structural Layers:When you look at the neck, the superficial coverings hide an intricate highway beneath. What exactly counts as a deep structure? In gross anatomy, the deep structures include every...
The Thymus: Structural Organization and Lifecycle Changes:Let us explore our first visceral organ: the thymus. Have you ever wondered where your immune cells go to school? The thymus is a soft, pinkish-gray, lobulated <term def="an organ ...

2The Thyroid Gland: Topography, Relations & Clinical Pathology

5 Micro-Bites
Thyroid Morphology, Vertebral Span, and Fascial Sheaths:Look at the front of your throat: resting directly over the windpipe is the thyroid gland. It is a butterfly-shaped, highly vascular, bilobed endocrine organ responsible for settin...
Thyroid Relations: Anterior, Lateral, and Medial Neighbors:Because the thyroid sits at a busy anatomical crossroads, surgeons must know its surrounding relations intimately in three directions: - **Anterior Relations (In front)**: The fro...

3The Parathyroid Glands: Regulation, Vasculature & Tetany

3 Micro-Bites
Parathyroid Topography, Number, and Histology:Turn the thyroid gland around and look at its back surface: here sit the parathyroid glands. They are four small, yellowish-brown endocrine glands nestled at the upper and lower po...
Parathyroid Blood Supply, Drainage, and Secretomotor Control:Because these tiny glands produce a hormone critical for survival, where does their blood come from? - **Arteries**: The parathyroid glands receive their main arterial blood supp...
