The Peripheral Nervous & Endocrine System
Name of Cranial Nerve/Functions
Abducens-lateral rectus muscle
Facial-motor to muscles of facial expressions;sensory taste
Trigeminal-motor function for chewing and bitting
Vestibulocochlear-Sensory for hearing and balance
Trochlear-Superior oblique muscle of eye
Oculomotor-Mostly motor function/most muscles of eye,eyelid,pupillary constriction
Vagus-control heart and lungs & muscle contraction
Optic-arises from retina of the eye and functions in vision
Accessory-Swallowing and movements of head
Olfactory-Sensory nerve that functions in sense of smell
Hypoglossal-movement of tongue during speech and swallowing
Glossopharyngeal-secretion of saliva
Endocrine organs
hypothalamus-produces hormones stored in pituitary gland
pineal gland-regulates sleep cycles, temp, and alertness
pituitary gland-hormones that stimulate endocrine glans
parathyroid-increases blood calcium levels
thyroid-control metabolic rate and decrease calcium levels
adrenal gland-hormones that control mineral balance and inflammation
pancreas-produces insulin and glucagon to regulate blood sugar levels
ovary-produces estrogen and progesterone
testes-produces testosterone
Hormones
Prolactin- increases and maintains milk secretion
ACTH- adrenal gland to release cortisol
FSH-egg maturation in the ovary and release sex hormones
Oxytocin- contraction of uterus during labor
ADH-regulates fluid balance by increasing body fluid volume on decreasing urine output
hGH- growth during puberty
LH- development of ovary and testes
Melatonin- controls sleep cycles, temp and alertness
TSH- control basal metabolic rate by releasing thyroxine
OTC- increases blood calcium levels
Adenohypophysis- production and secretes hormones
Thymosin- develop of the T-cells involves in the immune response
Neurphypophysis- stores and secretes oxytocin
GH- causes growth and division of cells
MSH-produces melanin in the skin
Divisions of the Autonomic NS
Sympathetic
Lungs-dilates bronchi
muscle- increases muscle function
Blood vessel- constricts
Digestive tract- inhibits it
Heart-accelerates it
Urinary- relaxes
Salivary glands- inhibits flow of saliva
Sweat glands- increases sweat
eyes- dates pupils
Reproductive- inhibits of erection
function-shuts down digestive functions
Parasympathetic
Lungs- constricts bronchi
Muscle- relaxes
Blood vessels- Disabtes
Digestive tract- stimulates digestion
Salivary glands- stimulates saliva
Urinary- constrict bladder
Heart- Slow rate
Sweat glands- inhibits sweat
eyes- constricts them
Reproduction- stimulates erection
Function- digestion, kidney filtration
