what type of senses are touch, pressure, vibration, itch, tickle, warm, and cold?
somatic senses
what type of senses provide information about conditions within internal organs?
visceral senses
what type of receptor is sensitive to touch, pressure, vibration, proprioception, hearing, and equilibrium?
mechaoreceptors
what type of receptors detect changes in temperature?
thermoreceptors
what type of receptors respond to pain?
nociceptors
what type of receptor detects light?
photoreceptors
what type of receptor detects taste and smell?
chemoreceptors
what type of receptor picks up on fine touch, pressure, and slow vibration?
meissner corpuscle
what type of receptor picks up on fine touch and pressure?
merkle disc
what type of receptor picks up on crude touch and stretch?
ruffini corpuscle
what type of receptor picks up on pressure and fast vibration?
pacinian
what is the order of mechanoreceptors on touch to the skin?
meissner, merkel, ruffini, and pacini
what is pain felt on the skin?
superficial somatic pain
what is pain felt in skeletal muscles, joints, tendons, and fascia?
deep somatic pain
what type of pain is felt in visceral organs?
visceral pain
what type of pain is felt far away from the stimulated organ?
referred pain
what monitors the change in muscle length?
muscle spindles
what is responsible for the stretch reflex?
muscle spindles
what is located the junction of tendons and muscles?
golgi tendon organs
what monitors tension?
golgi tendon organs
what forces a muscle to relax?
golgi tendon organs
what is located in and around the joint capsule of synovial joints?
joint kinesthetic receptors
what monitors joint position and joint movement?
joint kinesthetic receptors
what are the sensory neurons?
first order, second order, and third order neurons
what conducts ascending impulses from the brain stem or spinal cord to the thalamus on the opposite side of the brian?
second order neurons
what conducts ascending impulses from the thalamus to motor neurons?
third order neurons
what does it mean to occur on the opposite side of the brain?
decussation
what are the two neurons in the pathway from the brain to skeletal muscle?
upper and lower motor neurons
what extends from the brain to the brainstem or spinal cord?
upper motor neuron
what passes via cranial or spinal nerves to the neuromuscular junction to innervate skeletal muscle?
lower motor neurons
