banner2 info because the bladder is

innervated by sympathetic innervation

in segmented 12-2

parasympathetic innervation in segments S2 to S4

and somatic innervation namely net

pudendus there are two main phases

filling phase and emptying phase the process

for micturition requires cooperation of

autonomic and semantic nerves [Music]

[Music]

afferent nerve endings in the

detrusor muscle are activated then the

afferent nerve fibers carry the infusion to the

posterior horn of the thoracolumbar spinal cord

the info is forwarded to the sympathetic preganglionic nucleus

In segments t12 to L2 the

preganglionic efferent fibers to the

inferior mesenteric ganglion Um

postganglionic fibers IQ run through the

inferior hypogastric plexus to the

bladder wall and the internal sphincter muscle

there is relaxation of the

detrusor muscle and contraction of the internal sphincter muscle

for relaxation of the

detrusor muscle the neurotransmitter that

will be beta-adrenergic While

for muscle contraction

internal sphincter neurotransmitter

released Alpha adrenergic in the

spinal cord sacral segment there are

motor neurons called nucleoid porno

fountains coret center or other name

pontien continents Center

phone storage center is in the

lateral cell phone Therefore it is

also called the lateral nucleus region contents

coret center innervates the nucleus on

uh in the sacral spinal cord fibers

from the nucleus ono are the

pudendal nerve that innervates the

external sphincter muscle

Hi Polytron from Ponpes orange center

this is to maintain the tone of the external sphincter Bengkulu the

infusion is sent

continuously to keep the

so that when coughing sneezing or laughing

urine does not flow out

involuntarily all This process continues

until the urinary bladder is full

as a note the pudendal nerve

Indonesia

hi when the urinary bladder is

full beyond the threshold of stimulation the

afferent nerve endings in the detrusor muscle

are activated due to muscle strain

Peren foam is sent to the God nucleus in the

spinal cord segments 1 to S2 there are

also fibers that form a

direct reflex arc with the

parasympathetic preganglionic nucleus

Hi preganglionic fibers run

into the inferior hypogastric plexus

where there are parasympathetic postganglionic neurons IX there is a

contraction of the

detrusor muscle and relaxation of the internet printer muscle for

for

detrusor muscle contraction the neurotransmitter

released acetylcholine While for

inhibition or relaxation of the

internal sphincter muscle the parasympathetic nerve

puts electricity offside in

normal conditions the process of this nerve arch

will be suppressed by central nervous control

Okay we return to the nucleus get

afferent fibers God nuclei run up

to the mesencephalon Regency to Feri

I stirred the year Grey in Messenger Balloon

Hi Barry I stirred know Grey sends

impulses copotin micturition Center in

pond content micturition center

also called the nucleus baring ton or medial

region micturition center this content then

sends efferent input to the

spinal cord efferent fibers to the

preganglionic neurons Nick parasympathetic

located in segments es 2-4 occurs

contraction of the detrusor muscle and

content micturition center also contacts with

interneurons that will initiate the bisi

nucleus ono so that relaxation

of the external sphincter muscle occurs

Hi ponten micturition center also inhibits

sympathetic neurons so that the

process of micturition occurs [Music]

[Music]

Hi so the pontien micturition center plays a role in

activating the parasympathetic nerves

inhibiting the sympathetic nerves and

inhibiting the nucleus so

this whole is called the reflex pathway Kino bullboss

finalis bulbo means brainstem so the

journey of this reflex pathway from the

spinal cord to the brainstem then

back to the spinal cord this reflex pathway

can be influenced by the

central nervous components above the sport distance from the

Bird nucleus in addition to Feri Aquatic Grey

there are also those that go up to the thalamus and

cerebral cortex so that we become

aware that there is a feeling of wanting to urinate the process

process

involves the medial prefrontal cortex

Thalamus hypothalamus insula convection

nguli anterior and basal ganglia

after analysis it turns out that the condition does not

allow for perfect urination

medial prefrontal will send

inhibitory impulses to Feri I stir sabre

so that the urination process is inhibited [Music]

then the motor cortex sends efferent

impulses through the

pyramidal tract or corticospinal fibers of the

pyramidal tract to the sacral and

activates motoneurons or

ponoes nucleus PIN kuse Frendy

will go through the pudendal nerve to cause

contraction of the external sphincter muscle

and pelvic floor muscles which is done

voluntarily or consciously so

to hold urination requires the role

of the sympathetic nerves and control from the

motor cortex through the

pyramidal tract pay attention to the medial prefrontal protest

inhibiting Perry I stir tal

Grey and the motor cortex sends

efferent infusion through the pyramidal tract [Music]

[Music]

Complex process to assess the situation

and conditions continues after a

safe decision is obtained and will

start for

this inhibition of Ferry I stir tal

Grey and infusion from the tract

corticospinal to sacral Motor Neuron

will be stopped [Music]

[Music]

Hi so that the process of urination occurs

Hi tends other data even though

efforts have been made to hold urination when it

has reached the critical stretching point

of the detrusor muscle, a

large ampere infusion will be released

Hi so that activation of the reflex pathway occurs

Vino bullboss finalist large infusion

due to critical stretching will

activate this reflex pathway despite the

imbibition of the cortex so that

urination occurs due to being

unable to hold urination lazy Supra tree

will cause loss of

voluntary control for urination and awareness when

urinating or Incontinence occurs

hyperreactive and [ __ ] from the muscles

and cursor which are the characteristics of

Um Lesions but Attitude Synergy hot and

good levels remain good

selection in the brainstem to the

spinal cord segment N1 will disconnect the

control center mix ID iPhone with the

spinal cord causing

hyperreflexia and spasticity of the bladder

bladder volume can be Normal

or reduced with

more frequent emptying contractions In addition,

lesions in the brainstem to the F1 segment

will cause detrusor

finger dyssynergia, namely where detrusor contractions

involuntary without external sphincter relaxation

due to the disruption of the pathway from the

fontin micturition center that

inhibits the conus nucleus,

causing incomplete bladder emptying.

Traction and crusor without

external sphincter muscle sensation will

cause incomplete bladder emptying

and intermittent urine output.

Lesions in segments 2-4

will cause detrusor areflexia

or type l m n selection paralysis and

cause overflow incontinence or

continual gripping even though it is

very full there is no contraction of the

detrusor muscle, resulting in

overflow incontinence because the
