[The human pineal gland. Study performed on 747 glands]

Area of Science:

• Endocrinology
• Histology

Context:

• The human pineal gland's weight and composition are crucial for understanding its function.
• Variations in pineal gland weight can indicate underlying health conditions.

Purpose:

• To investigate the variability in human pineal gland weight and microscopic structure.
• To determine correlations between pineal gland characteristics and disease states.

Summary:

• Human pineal gland weight is highly variable and shows seasonal changes.
• Pineal gland weight is similar in cancerous and non-cancerous individuals but lower in hepatic diseases.
• Microscopic analysis revealed diverse origins for pineal concretions, including vessel walls and pinealocytes.

Impact:

• Provides baseline data on pineal gland morphology.
• Highlights potential diagnostic indicators related to hepatic diseases.
• Enhances understanding of pineal gland physiology and pathology.
