somatic senses and motor control Flashcards
what are special senses within the body
balance
hearing
sight
taste
smell
chemoreceptors
detect chemicals dissolved in fluid eg taste
photoreceptors
detect change in light intensity, colour and movement Eg eyes
mechanoreceptors
detect mechanical pressure Eg touch, pressure
free nerve endings receptor
nociceptors
thermoreceptors
hair root plexuses
merkel nerve endings
encapsulated nerve ending receptors
Meissner (tactile)
Ruffini (bulbous)
Pacinian (lamellar)
tactition
sense of touch, pressure, vibration,tickle, itch
superficial mechanoreceptors
meissners corpuscles
merkel nerve endings
olfaction area
required for smell found in the superior and upper nasal septum
epithelium involved with taste
gustatory receptor cells
supporting cells
basal cells
4 types of papillae
circumvallate
foliate
fungiform
fillform
5 types of taste
bitterness
saltiness
sweetness
umami
sourness
what detects linear motion
saccule and utricle
what is static equilibrium
maintenance of the body position relative to the force of gravity
what 3 detects angular acceleration
anterior, posterior, lateral
dynamic equilibrium
maintenance of body position in response to sudden movements
flow of tears
lacrimal gland ->excretory lacrimal ducts ->superior or inferior lacrimal canal ->lacrimal sac ->nasolacrimal duct -> nasal cavity
extra ocular muscles
eye muscles
6 muscles of the eye
superior rectus
lateral rectus
inferior rectus
inferior oblique
medial rectus
superior oblique
what are the general somatic senses
tactician
nociception
proprioception
nociception
unpleasant sensations arising from noxious stimuli
thermoception
sense of presence or absence of heat
proprioception
awareness of the bodies position in space
types of proprioceptors
tendon organ
muscle spindle
stretch reflex
