Peripheral Nervous and Endocrine System
Names of Cranial Nerves and Functions
Olfactory
sensory nerve that functions in sence of smell
Optic
arises from retina of the eye and functions sin vision
Oculomotor
mostly motor functions most of muscle eye, eyelid , and pupillary constriction
Trochlear
superior oblique muscle of eye
Trigeminal
motor-chewing sensory-skin of face
Abducens
laeral rectus eye muscle abducts the eye
Facial
motor-muscles of face expression sensory-taste
Vestibulocholear
sensory-hearing and equilibrium
Glossopharygeal
motor-secretion of saliva sensory-taste,regulation of blood pressure ans proprioception of muscles involved in swallowing
Vagus
-motor-smooth muscle contraction and relaxsation,secretion of digestive fluids sensory-from visual organs it supplies and proprioception
Accesory
motor-swallowing and movements of head sensory-proprioception
Hypoglossal
motor-movement of tounge during speech and swallowing sensory-proprioception
Divisions of Autonomic Nervous System
Sympathetic
originates in Thoracolumbar segments of spinal cord, Synapses in ganglia near spinal cord
Parasympathetic
originates in brainstem and sacral
Names of Endocrine Organs, Hormones, & Functions
Pineal Body
Melatonin-controls the sleep cycle , alertness and temperature
"master gland" signals other glands to produce their hormones when needed
Anterior lobe
makes and releases hormones under the control of the hypothalamus
Hypothalumus
produses hormones that stimulates the pineal gland
Posterior Lobe
stores and secretes hormones that are made in the hypothalumus ,such as antidiuretic
oxytocin
stimulates contraction of tthe uterus during labor and milk lett down
Follicle stimulating hormone
stimulates egg maturation in ovary and release sex hormones
Luteinizing hormone
involved with development of ovaries and testes
Adrrenocorticotropic hormone
stimulates the adrenal gland to release cortisol
human growth hormone
stimulates growth during infancy and puberty
prolactin
initiates and maintains milk secretion
Thyroid stimulating hormone
controls basal metabolic rate by releassing thyroxine
Melanocyte Stimulating hormone
stimulates productionn of melanin in the skin
Differnces between Functions of Divisions
Neurotransmitters(Sympathetic)
Epinephrine and Norepinephrine
Long pre ganglionic and short postganglionic nueron
Effector Organs
salivary glands,digestion and reproduction organs
Neurotrasmitters(Parasympathetic)
Acetylcholine
Short pre-ganglionic and long postganglionic neuron
Effector Organs
eyes lungs heart ect
Effects of Parasympathetic & Sympathetic on Organs
Sympathetic
"E"
excersize,excitement,emergency, and embarassment
Parasympathetic
"D"
digestion, defecation, diuresis
