Anatomy of the Adrenal Glands01:17

Anatomy of the Adrenal Glands

3.2K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...

External Anatomy of the Kidney

2.1K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla01:27

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

1.7K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

2.3K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Renal Corpuscle01:20

Renal Corpuscle

4.2K
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Area of Science:

  • Endocrinology
  • Pathology

Background:

  • Adrenal incidentalomas are common findings during abdominal imaging.
  • Their differential diagnosis can be challenging, requiring consideration of various adrenal and non-adrenal lesions.

Purpose of the Study:

  • To highlight the presence of splenules within the adrenal glands.
  • To emphasize the importance of considering splenules in the differential diagnosis of adrenal incidentalomas.

Main Methods:

  • Review of relevant literature and case reports.
  • Pathological examination of adrenal tissues.

Main Results:

  • Splenules, which are small portions of splenic tissue, can be found incidentally within the adrenal glands.
  • These ectopic splenic tissues may mimic or be mistaken for adrenal tumors.

Conclusions:

  • The presence of splenules in the adrenal glands is a recognized phenomenon.
  • Radiologists and clinicians should include splenules in the differential diagnosis of adrenal incidentalomas to avoid misdiagnosis and unnecessary interventions.
