Introduction

The adrenal cortex is the outer layer of endocrine tissue in the adrenal gland. It consists of three zones: the zona glomerulosa, the zona fasciculata, and the zona reticularis. The zona glomerulosa primarily secretes mineralocorticoids, which regulate electrolyte and water-salt metabolism in the body. The zona fasciculata mainly produces glucocorticoids, which play a role in regulating the metabolism of fats and proteins. The zona reticularis primarily secretes adrenal hormones.

　　Under normal circumstances, the adrenal cortex is the outer layer of endocrine glandular tissue of the adrenal gland. Specifically:
　　The adrenal cortex consists of three layers: the outer zona glomerulosa, the middle zona fasciculata, and the inner zona reticularis. The zona glomerulosa primarily secretes mineralocorticoids, which regulate electrolyte and water-salt metabolism in the body. The zona fasciculata mainly produces glucocorticoids, which help regulate the metabolism of fats and proteins. The zona reticularis secretes adrenal hormones and small amounts of sex hormones. Abnormal levels of mineralocorticoids or glucocorticoids in the body may lead to conditions such as adrenal cortical hyperfunction, adrenal cortical insufficiency, or adrenal cortical hyperplasia.
　　Therefore, when a patient shows signs of adrenal cortical dysfunction, timely medical evaluation is necessary. Treatment should be carried out under a doctor's guidance using appropriate medications to prevent further, more serious damage to the body. Additionally, maintaining a positive mood, consuming vitamin-rich foods, and engaging in moderate exercise in daily life can help strengthen the body's constitution and protect the glands.

What surrounds the kidney and adrenal gland?

Under normal circumstances, the renal fascia surrounds the kidney and adrenal gland. The renal fascia lies outside the perirenal fat capsule and is a connective tissue membrane that envelops the adrenal gland and the outer surface of the kidney. The renal fascia sends septa (trabeculae) inward to connect with the perirenal fat capsule and the renal fibrous capsule, helping to stabilize and fix the position of the kidney. The portions of the renal fascia located anterior and posterior to the kidney are known as the anterior renal fascia and posterior renal fascia, respectively.

Can adrenal gland thickening cause hypertension?

Adrenal gland thickening may cause hypertension, and patients should cooperate with their doctors to receive targeted treatment. The adrenal glands are a pair of endocrine glands located above the kidneys. Both the adrenal cortex and medulla secrete various hormones, such as aldosterone, cortisol, epinephrine, and norepinephrine. In severe cases, this condition can lead to adverse effects including palpitations, shortness of breath, chest tightness, and even coma.

What is the adrenal gland?

Under normal circumstances, the adrenal glands are important endocrine organs in the human body. The adrenal glands are located above the kidneys, one on each side; the left adrenal gland is crescent-shaped, while the right adrenal gland is triangular. Together with the kidneys, they are enclosed by renal fascia and adipose tissue, occupying a relatively fixed position within the retroperitoneal space. This organ consists of two parts: the cortex and the medulla.
