The High Council of Sella
This depression in the body of the sphenoid bone lodges the pituitary gland and is bounded by the anterior and posterior clinoid processes.
The Sella Turcica
This central portion of the thyroid gland connects the two lateral lobes and typically overlies the second and third tracheal rings.
The Isthmus
The head of the pancreas is situated within the concavity of this segment of the small intestine.
The Duodenum
While both glands are retroperitoneal, the right adrenal gland is typically shaped like this geometric figure.
A Pyramid
These arteries originate from the abdominal aorta at the level of the second lumbar vertebra (L2).
The Testicular Arteries
This lateral fold of peritoneum carries the ovarian vessels and nerves from the pelvic brim to the ovary.
The Suspensory Ligament of the Ovary (Infundibulopelvic)
Most individuals possess this number of parathyroid glands, typically found on the posterior aspect of the thyroid lobes.
Four
The pineal gland is a small, cone-shaped body attached to this specific part of the diencephalon.
The Roof of the Third Ventricle
Situated immediately superior to the pituitary stalk, this neural structure is at risk of compression from pituitary adenomas.
The Optic Chiasm
This branch of the vagus nerve ascends in the tracheoesophageal groove and is closely related to the inferior thyroid artery.
The Recurrent Laryngeal Nerve
This major vein is formed posterior to the neck of the pancreas by the union of the superior mesenteric and splenic veins.
The Hepatic Portal Vein
The adrenal medulla receives unique innervation from these specific fibers, which function as modified sympathetic ganglion cells.
Preganglionic Sympathetic Fibers
This double-layered serous sac, derived from the peritoneum, covers the anterior and lateral surfaces of the testis.
The Tunica Vaginalis
This specific portion of the broad ligament attaches the anterior border of the ovary to the posterior layer of the broad ligament.
The Mesovarium
The parathyroid glands primarily receive their arterial blood supply from these specific vessels.
The Inferior Thyroid Arteries
These calcium carbonate and phosphate deposits are frequently seen in the pineal gland of adults on radiographs.
Corpora Arenacea (Brain Sand)
These paired venous spaces border the pituitary gland laterally and contain the internal carotid artery and several cranial nerves.
The Cavernous Sinuses
This arterial vessel is the first branch of the external carotid artery and supplies the upper pole of the thyroid.
The Superior Thyroid Artery
This branch of the celiac trunk follows a tortuous path along the superior border of the pancreatic body and tail.
The Splenic Artery
This venous vessel receives the drainage from the left adrenal gland, whereas the right adrenal vein drains directly into the IVC.
The Left Renal Vein
Lymphatic drainage from the testes bypasses the inguinal nodes and terminates in these abdominal nodes.
The Para-aortic (Lumbar) Lymph Nodes
During pelvic surgery, the ovarian artery must be carefully identified as it crosses anterior to this muscular tube.
The Ureter
These specific parathyroid glands are embryologically derived from the third pharyngeal pouch and often migrate with the thymus.
The Inferior Parathyroid Glands
The pineal gland lies in the midline, immediately superior to these two rounded structures of the midbrain.
The Superior Colliculi
This vascular network allows hypothalamic releasing and inhibitory hormones to travel from the median eminence to the anterior lobe.
The Hypophyseal Portal System
This layer of deep cervical fascia encloses the thyroid gland, anchoring it to the larynx and trachea.
The Pretracheal Fascia
This specific projection from the lower part of the pancreatic head extends medially behind the superior mesenteric vessels.
The Uncinate Process
The adrenal glands are separated from the kidneys by this thin septum, though both are enclosed within the renal fascia.
Perirenal Fat
This network of veins in the spermatic cord helps maintain a testicular temperature of approximately 35°C.
The Pampiniform Plexus
This cord-like structure connects the medial pole of the ovary to the lateral angle of the uterus.
The Ligament of the Ovary
The superior parathyroid glands are generally found at the level of the inferior border of this laryngeal cartilage.
The Cricoid Cartilage
Postganglionic sympathetic fibers reach the pineal gland from this specific cervical ganglion.
The Superior Cervical Ganglion
Arising from the internal carotid artery, these specific vessels supply the pars tuberalis and the infundibulum.
The Superior Hypophyseal Arteries
Present in approximately 50% of people, this anatomical variant extends upward from the isthmus toward the hyoid bone.
The Pyramidal Lobe
Unlike the head and body, the tail of the pancreas is intraperitoneal, contained within this ligament.
The Splenorenal (Lienorenal) Ligament
This specific artery, supplying the adrenal gland, arises directly from the inferior phrenic artery.
The Superior Suprarenal Artery
This thick, fibrous white capsule lies immediately deep to the visceral layer of the tunica vaginalis.
The Tunica Albuginea
Pain from the ovaries is referred to this dermatome, which corresponds to the level of the umbilicus.
T10
During thyroidectomy, these glands are often preserved by leaving this part of the thyroid capsule intact.
The Posterior Capsule
This large venous channel, which drains the internal cerebral veins, is situated immediately superior to the pineal gland.
The Great Cerebral Vein (of Galen)
