____________ initiate and direct voluntary activity
UMN initiate and direct voluntary activity
Damage to white matter results in _______ signs.
Damage to white matter results in UMN signs.
Grey matter damage results in _________ signs
Grey matter damage results in LMN signs
___________ responsible for proximal and extensor muscles. Importante for posture and balance and whole limb movments.
Ventromedial system responsible for proximal and extensor muscles. Importante for posture and balance and whole limb movments.
____________ travel down the spinal cord in dorsolateral or ventromedial systems.
UMN travel down the spinal cord in dorsolateral or ventromedial systems.
_________ Bladder
Continuous leakage
No tone in urethralis muscle
Manual expression of bladder with little to no resistance
LMN Bladder
Continuous leakage
No tone in urethralis muscle
Manual expression of bladder with little to no resistance
SNS innervation of the bladder by _____ nerve
SNS innervation of the bladder by Hypogastric nerve
Lesion in the sacral region of the spinal cord results in ______ bladder.
Lesion in the sacral region of the spinal cord results in LMN bladder.
________ nerve inhibits contraction of the detrussor muscle for urine storage.
Hypogastric nerve inhibits contraction of the detrussor muscle for urine storage.
________ clinical signs are seen in regions of the body directly innervated by damaged segments.
LMN clinical signs are seen in regions of the body directly innervated by damaged segments.
Clinical signs of _________ damage are “decreased” (muscle tone, etc)
Clinical signs of LMN damage are “decreased” (muscle tone, etc)
___________ maintain muscle tone, support and posture
UMN maintain muscle tone, support and posture
Damage to ________ matter results in motor commands unable to reach spinal cord segments caudal of damage and sensory defects at the region and caudal to damage.
Damage to White matter results in motor commands unable to reach spinal cord segments caudal of damage and sensory defects at the region and caudal to damage.
Damage to _______ matter results in afferent information not being sent to the brain and efferent information not sent to the muscles. Cannot support reflexes.
Damage to Grey matter results in afferent information not being sent to the brain and efferent information not sent to the muscles. Cannot support reflexes.
__________ terminate on LMN and influence their activity.
UMN terminate on LMN and influence their activity.
Somatic innervation of the bladder by ______ nerve.
Somatic innervation of the bladder by Pudendal nerve.
_____________ responsible for distal and flexor muscles. Important for fractionated, precise movements.
Dorsolateral System responsible for distal and flexor muscles. Important for fractionated, precise movements.
PSNS innervation of the bladder by ________ nerve.
PSNS innervation of the bladder by Pelvic nerve.
Damage to the _________ system causes decreased or absent voluntary movement caudal to the lesion
Damage to the ventromedial system causes decreased or absent voluntary movement caudal to the lesion
Lesion in crainial cervical region to lumbosacral region of the spinal cord causes _______ bladder.
Lesion in crainial cervical region to lumbosacral region of the spinal cord causes UMN bladder.
