Every function is controlled by _____ system
Nervous System
What is the difference between the PNS & CNS?
PNS: -detect environmental stimuli & pass info to the CNS - carry out the order given by the CNS CNS: -Receive & analyze info -transmit decisions back to the PNS
Afferent Neurons Vs Efferent Nuerons
Afferent: carry info from sensory neurons to the CNS
-stumili from skin ->dorsal horn
Efferent: Carry info form the CNS to motor neurons
-back of the muscle -> skin
Trochlear
Motor
Trigeminal
Sensory (face, sinuses, teeth)
Abduscent
Motor: External rectus muscle (side eye muscle)
Facial
motor muscles of the faec
Vestibulocochlear
Sensory: inner ear
Glossopharyngeal
Motor: controls swallowing
Vagus
Motor: motor hear lungs bronchi
Accessory
Motor:
Hypoglossal
Motor: muscle of the tongue
Intermediate
Major Salivary glands in the mouth
Metencephalon
pons: sensory relay
Cerebellum: Maintaining posture, timing, planning movements
Myelencephalon
Medulla: controls basic life functions breathing heart rate
