5.3 neuro - vestibular

Question 1

what are the receptor organs for equilibrium of the vestibular apparatus

Answer 1

saccule, utricle, semicircular canals

Question 2

what are the two types of equilbrium

Answer 2

static: maintenance of the position of the body relative to the force of gravity
dynamic: maintenance of the position of the body in response to sudden movements / acceleration

Question 3

what membrane is involved in static equilibrium

Answer 3

otolithic

Question 4

what is a capula

Answer 4

glycoprotein layer, helps the body sense spacial orientation, otolithic membrane of the maculae

Question 5

what are the sensory structures in the semicircular canals

Answer 5

ampulla

Question 6

Answer 6

capula

Question 7

Answer 7

hair cell of maculae (ampulla of semicircular canals, static) or cristae (utricle and saccule, dynamic), vestibular gangion, vestibular nuclei brain stem (pons and medulla), ventral posterior nucleus of the thalamus
