The Peripheral Nervous/Endocrine System
arises from retina of the eye and functions in vision
mostly motor function- most of muscles of eye,eyelid and pupillary constriction.
sensory- nerve that functions in sense of smell
Superior oblique muscle of eye.
3 branches-motor-chewing sensory-skin of face
Laeral rectus eye muscle abducts the eye
motor-muscles of facial expression; sensory-taste
Sensory-hearing and equilibrium(balance)
motor-secretion of saliva; Sensory- taste
Autonomic Nervous System
Sympathetic Nervous System
Associated with the "fight or flight" response
Short pre-ganglionic/long postganglionic
Originates in the thoracolumbar (T1-T2)
Neurotransmitters: Epinephrine and norepinephrine
Parasympathetic Nervous System
Associated with the "daily" body functions
Long pre-ganglionic/long postganglionic
Originates in brainstem and sacral (S1-S4)
Produces hormones that stimulate the pituitary gland.
"Master gland' that signals other glands to produce hormones.
Makes and releases hormones
Stores and releases hormones such as antidiuretic hormone and oxytocin
Controls sleep cycles,alertness and temperature.
Stimulates contraction of the uterus during labour and milk
Regulates fluid balance by increasing body fluid volume and decreasing urine output.
Follicle stimulating hormone (FSH)
Stimulates egg maturation in the ovary and release sex hormones
Adrenocortictropic hormone (ACTH)
Stimulates the adreanal gland to release cortisol
Human growth hormone (HGH)
Stimulates growth during infancy and puberty
Thyroid stimulating hormone (TSH)
Control basal metabolic rate by releasing thyroxine
Parathyroid hormone (PTH)
Increases blood calcium levels.
Stimulates the development of the T-cells involved in the immune response.
Thyroid hormone (thyrokine T3-T4)
Control the basal metabolic rate
Controls blood sugar levels
Decrease blood glucose
Increase blood glucose
Stimulates the "fight or flight" response.
Responds to stress or injury and releases anti-inflammatory
"E" exercise,excitment,emergency, and embarrasment
"fight or flight" response
"D" Digestion,defecation, and divresis (urination)
Salivary glands,digestive and reproductive organs
"daily" body functions
