1. The nervous system and the endocrine system both regulate body activities, but they differ in speed and duration. The nervous system uses electrical impulses and neurotransmitters for rapid, short-term responses. The endocrine system uses hormones released into the bloodstream for slower, longer-lasting effects.
2. Hormones are chemical messengers secreted by endocrine glands directly into the bloodstream. They travel to target organs or tissues where they bind to specific receptors to trigger a response. Hormones regulate processes like metabolism, growth, and reproduction.
3. The pituitary gland is called the “master gland” because it controls many bodily functions by secreting hormones that regulate other endocrine glands. It influences growth, metabolism, and reproductive processes through hormones like growth hormone, TSH, ACTH, FSH, LH, and others.
4. Endocrine glands: pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, testes.
Exocrine glands: salivary, sweat, sebaceous, mammary, liver (bile), pancreas (digestive enzymes).
