What lobe does sensory information?

parietal lobe


What lobe does motor information?

frontal lobe


What is neuroplasticity?

change in the brain when learning new information


What are the three basic ways the brain can change to support learning?

Chemical, alter structure, and alter function


What is the leading cause of long term disability in adults in the world?



What are the two lessons learned studying the brain after stroke?

neuroplasticity varies, what works for one person doesn't work for the other


What are the two types of stroke?

hemorrhagic and infarct


What lobe is responsible for language?

Left frontal


What lobe is responsible for putting tone and inflection in language?

R frontal


Compression of the radial nerve against the head of the humerus, Weakness in all radial nerve innervated muscles and sensation over the dorsal lateral
hand, thumb, and fingers

crutch palsy


Compression of the radial nerve from prolonged stretch in spiral groove of humerus under the common insertion of the deltoid and triceps which roofs over the spiral groove

Weakness in brachioradialis, wrist and finger extensors, and sensory loss over the dorsal lateral hand, thumb, and fingers

saturday night palsy


what are the terminal branches of the radial nerve and are they sensory or motor?

deep radial (motor) and superficial radial nerve (sensory)


Entrapment of the deep radial nerve (motor) as it passes thru the Arcade of Froshe in the supinator leading to weakness of the finger and wrist extensors

supinator syndrome


Compression of the superficial radial nerve as it enters
the hand
- Sensory loss over the dorsal lateral hand, thumb, and fingers

handcuff neuropathy


Ulnar nerve as it passes around the olecranon to enter the cubital tunnel
- Compression from holding head in hand with elbow flexed on edge of table, trauma to nerve from hiWng a point (table, countertop, etc)

retrocubital compression


Compression of the ulnar nerve in cubital tunnel
- Repetitive episodes of medial epicondylitis resulting in a thicken roof over tunnel compressing nerve in the tunnel
• Weakness in ulnar hand muscles, decreased sensation in proper digital ulnar, palmar ulnar and dorsal ulnar nerves.

cubital tunnel syndrome


Weakness in ulnar innervated hand muscles, sensa3on loss over palmar aspects of medial one and a half digits.

Pisiform-Hamate Syndrome


Boney spur on anterior distal humerus with a ligament stretching from spur to medial epicondyle, roofing over the medial neurovascular bundle, median nerve and brachial artery.

Can compress median nerve leading to a Pronator syndrome with a weak pronator and sensory loss over palmar aspect of lateral 3 1⁄2 digits and skin over thenar eminence

• Ligament of Struthers


Poorly localized forearm pain and weakness of flexion of the DIP joint of Digit 1 (flexor pollicis longus) and the DIP joints of Digit 2 & 3 ( flexor digitorum profundus of digits 2 & 3). Patient cannot make an "OK" sign with their thumb and index fingers as DIP joints do not flex due to muscle weakness.

anterior interosseous syndrome


Median nerve compressed between the two heads of the pronator teres
- Weakness in all median muscles distal to the pronator teres • Flexorcarpiradialis • Palmarislongus • Flexordigitorumsuperficialis
• Flexorpolliicislongus, • Flexordigitorumprofundus,Digits2&3 • Abd.Poll.Brevis • Opponenspollicis • Flexorpollbrevis • LumbricalI&II
- Sensory loss over palmar aspect of lateral 3 1⁄2 digits and skin over thenar eminence

pronator syndrome


Compression of the median nerve in the carpal tunnel
• Weakness of median innervated intrinsic hand muscles - Abd. Poll. Brevis
- Opponens pollicis - Flexor poll brevis - Lumbrical I & II
• Sensory loss over the palmar aspect of lateral 3 1⁄2 digits

carpal tunnel syndrome


medial wall of the motor homunculus is supplied by?

anterior cerebral a.


convexity of the motor homunculus

middle cerebral a.


thalamus is



globus pallidus and putamen



decreases facilitation of Interneuron

Decreased UMN firing


RMP moves closer to threshold

Decreased inhib of LMN


Decreases facilitation of LMN Tap tendon see more LMNs fire to muscle Hypereflexia

Decreased UMN firing


The most common nontraumatic condition and usually affects the upper plexus and shoulder girdle muscles

Neuralgia amyotrophy


Stretch injuries to the upper trunk may be combined with a C5 C6 root avulsion which is?

erb's palsy
