Introduction to Glands and Hormones

  • Glands are groups of secretory tissues classified into exocrine and endocrine types
  • Exocrine glands have ducts and release secretions into target organs (liver, salivary glands)
  • Endocrine glands are ductless and release hormones directly into blood

Comparison: Nervous vs Endocrine System

  • Both systems control and coordinate body activities and provide communication
  • Nervous system: Fast conduction, localized effect, short-lived response, direct pathway
  • Endocrine system: Slow conduction, widespread effect, long-lasting response, bloodstream pathway

Pituitary Gland - The Master Gland

  • Pea-sized whitish gland (5g) hanging from hypothalamus by infundibulum
