Physiology :Higher Brain Functions & Renal

Characterized by uniform arrangement

Highly affected by gravity

The density of the cupula is higher than the endolymph

It is a chemoreceptor

. May occur due to stoppage of rotation

Due to momentum of endolymph

Not related to menier's disease

. Its nervous pathway are vestibulo-cerebello-thalamo-cortical and vestibulo-reticulo-thalamo-cortical

. Random arrangement of stereocillia

Uniform arrangement of stereocillia

The cells are covered by a gelatinous layer which is of the same density of the endolymph

It's not affected by gravity

It's stimulated in case of forward& backward tilt

It's stimulated in case of horizontal acceleration

It's stimulated in case of side by side tilt

Both a & b

Afferent arteriole

Arcuate artery

Interlobular artery

Efferent arteriole

Present in juxta medullary nephrons

Its macula densa act as baro receptor

Its juxtaglomerular cells are innervated by symp.

. Its macula densa is modified smooth muscle

Excretory func. In acute renal failure

Secretory func. In choronic renal failure

Homeostatic func. In acute renal failure

Homeostatic func. In choronic renal failure

Its function is concentration of urine

It's characterised by long loop of henl

It's characterised by autoregulation

It's characterised by absence of J.G.A
