Endocrine System
Nervous system
Autonomic Nervous System
Anatomical organization of the somatic and autonomic motor pathways
Sympathetic Nervous system
Anatomical organization of the sympathetic Nerves
Parasympathetic Pathways
Sensory Components of the Visceral Motor System
Neurotransmission in the Visceral Motor System
Autonomic Regulation of Cardiovascular Function
The Enteric Nervous System
Autonomic Regulation of the Bladder
Autonomic Regulation of Sexual Function
Female Reproductive organ
Higher Control of the Autonomic Nervous System
The Hypothalamus
Hypothalamus
Hypothalamic afferents from Limbic System
Hypothalamic afferents from Cerebral Cortex
Hypothalamic efferents to thalamus and mammillary body
Hypothalamic efferents to Pituitary gland and Frontal Lobe
Hypothalamic control of Endocrine system
Homeostatic processes can be analyzed in terms of control systems
Temperature Regulation
Feeding Behavior Is Regulated by a Variety of Mechanisms
Feeding Behavior
Dual Controlling Elements in the Hypothalamus Contribute to the Control of Food Intake
•Lateral Hypothalamus•Feeding center
•Medial Hypothalamus
•Satiety center
Food Intake Is Controlled by Short-Term and Long-Term Cues
Hypothalamus and Energy Homeostasis
Drinking Is Regulated by Tissue Osmolality and Vascular Volume
