Flashcards in Test 1 Deck (68)
What lobe does sensory information?
What lobe does motor information?
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?
What lobe is responsible for putting tone and inflection in language?
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
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
Compression of the superficial radial nerve as it enters
- Sensory loss over the dorsal lateral hand, thumb, and fingers
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)
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.
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
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.
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
