Integumentary System
Chapter 5
Sympathetic division of the ANS regulates sweat glands and
blood vessels of skin (therefore heat loss/retention)
Skin serves as heat loss surface
Skeletal System
Chapters 6–8
Nerves innervate bones and joints, providing for pain and joint
sense
Bones serve as depot for calcium needed for neural function;
skeletal system protects CNS structures
Muscular System
Chapters 9–10
Somatic division of nervous system activates skeletal muscles;
maintains muscle health
Skeletal muscles are the effectors of the somatic division

Endocrine System
Chapter 16
Sympathetic division of the ANS activates the adrenal medulla;
hypothalamus helps regulate the activity of the anterior pituitary
gland and produces the two posterior pituitary hormones
Hormones influence neuronal metabolism
Cardiovascular System
Chapters 17–19
ANS helps regulate heart rate and blood pressure
Cardiovascular system provides blood containing oxygen and
nutrients to the nervous system and carries away wastes
Lymphatic System/Immunity
Chapters 20–21
Nerves innervate lymphoid organs; the brain plays a role in
regulating immune function
Lymphatic vessels carry away leaked tissue fluids from tissues
surrounding nervous system structures; immune elements
protect all body organs from pathogens (CNS has additional
mechanisms as well)
Respiratory System
Chapter 22
Nervous system initiates and regulates respiratory rhythm and
depth
Respiratory system provides life-sustaining oxygen; disposes of
carbon dioxide
Digestive System
Chapter 23
ANS (particularly the parasympathetic division) regulates
digestive motility and glandular activity
Digestive system provides nutrients needed for neuronal health
Urinary System
Chapters 25–26
ANS regulates bladder emptying and renal blood pressure
Kidneys help dispose of metabolic wastes and maintain proper
electrolyte composition and pH of blood for neural functioning
Reproductive System
Chapter 27
ANS regulates sexual erection and ejaculation in males; erection
of the clitoris in females
Testosterone causes masculinization of the brain and underlies
sex drive and aggressive behavior
