What is the Endocrine System?
Hormone - Secreted chemicals that are
formed in specialized cells, travel in body
fluids, and act on specific target cells in other
parts of the body to change their functioning
Endocrine System - The internal system of
communication involving hormones, the
ductless glands that secrete hormones, and
the molecular receptors on or in target cells
that respond to hormones
Target Cells are those cells equipped to
respond to hormones
Endocrine glands which are hormonesecreting organs
Neurosecretory cells secrete hormones into
the blood
Signaling Molecules
Hormones: send regulatory messages
throughout the body in extracellular fluid
Endocrine signaling
Local Regulators - cells adjacent to or near
point of secretion
Neurotransmitters
Cytokines and growth factors
Nitric oxide
Prostaglandins - help regulate the
aggregation of platelets
Paracrine Signaling
Autocrine Signaling
Neurotransmitters and Neurohormones
Neuroendocrine Signaling
Synaptic Signaling
Pheromones
Chemical Classes of Hormones
Cellular Response Pathways
Water-Soluble
Hormones
Lipid-Soluble
Hormones
Multiple Effects of
Hormones on target
cells that have:
Different
receptors for the
hormone
Different signal
transduction
pathways
Different
proteins for
carrying out the
response
Simple Hormone Pathways
Insulin and
Glucagon: Control of
Blood Glucose
Diabetes Mellitus
Type 1 (InsulinDependent)
Type 2 (NonInsulinDependent)
Coordination of the Endocrine and
Nervous Systems
Invertebrates
Vertebrates
Posterior Pituitary Hormones
Oxytocin
Antideuretic hormone (ADH)
Anterior Pituitary Hormones
Each hypothalamic hormone is
either a releasing or inhibiting
hormone
Hormone Cascade Pathway
Tropic Hormones
Follicle-stimulating Hormone
(FSH)
Luteinizing Hormone (LH)
Adrenocorticotropic hormone
(ACTH)
Thyroid-stimulating hormone
(TSH)
Nontropic Hormones
Prolactin (PRL)
Melanocyte-stimulating
hormone (MSH)
Growth Hormones (GH)
Endocrine Glands
Thyroid Gland
Control of Metabolism and
Development and Homeostasis
Thyroid Hormone:
Triiodothyronine (T3) and
thyroxine (T4)
