• exteroceptors response to outside stimuli
• interceptors respond to inside stimuli
• proprioceptors response to degree of stretch
• mechanoreceptors response to mechanical force
• thermoreceptors respond to temperature change
• chemoreceptors respond to chemicals ex. ph
• photoreceptors respond to light
• nociceptors respond to pain
• the somatic nervous system is voluntary and deals with skeletal muscle
• the autonomic nervous system is involuntary and deals with smooth and cardiac muscle plus glands
• the sympathetic nervous system is the fight or flight response (exercise)
• the parasympathetic nervous system is basal and conserves energy
• the muscle spindle is the stretch recpetor
• the Golgi tendon is the tension receptor
• the ipsilateral response occurs on the same side of the body
• the contralateral response occurs on the opposite side of the body
• autogenic inhibition deals with excess tension by having relaxation
• in reciprocal inhibition the agonist muscle contracts causing the antagonist muscle to relax
• spinal reflexes are somatic but involuntary
• the stretch reflex deals with excess stretch by contracting ex. pateller
• the tendon reflex deals with excess tension by relaxing the muscle ex. GTO
• the flexor reflex is the withdrawal reflex
• the crossed-extensor reflex coordinates for both sides
• The trigeminal nerve is the biggest cranial nerve and is responsible for sensation of the face
• the VII nerve is in the right hemisphere
• the vagus nerve is responsible for the parasympathetic nervous system
