Nerves and meridians 2 Flashcards
What is the meridian relation function of the Radial nerve?
Supplies extensor muscles of the arm and forearm; sensory to the posterior arm, forearm, and hand.
What is the dermatome function of the Musculocutaneous nerve?
Innervates anterior arm muscles (biceps, brachialis); provides lateral forearm sensation.
What is the motor function of the Radial nerve?
Supplies extensor muscles of the arm and forearm; sensory to the posterior arm, forearm, and hand.
Which nerve innervates the quadriceps femoris?
Femoral nerve (L2-L4), responsible for knee extension.
What is the myotome function of the Ulnar nerve?
Controls hand movements, including finger abduction and adduction; provides sensation to the medial hand.
What is the motor function of the Ulnar nerve?
Controls hand movements, including finger abduction and adduction; provides sensation to the medial hand.
What is the meridian relation function of the Sciatic nerve?
Innervates posterior thigh muscles and splits into tibial and fibular nerves; sensory to posterior leg and foot.
What is the dermatome function of the Fibular nerve?
Superficial branch controls foot eversion; deep branch controls dorsiflexion and toe extension.
What is the primary sensory area of the musculocutaneous nerve?
Lateral forearm, through its continuation as the lateral cutaneous nerve of the forearm.
What is the meridian relation of the tibial nerve?
Kidney & Liver Meridians, particularly at the medial ankle and foot.
What is the myotome function of the Fibular nerve?
Superficial branch controls foot eversion; deep branch controls dorsiflexion and toe extension.
Which nerve is responsible for finger abduction and adduction?
Ulnar nerve (C8-T1). It innervates the interossei muscles that control these movements.
What is the primary sensory region of the deep fibular nerve?
The web space between the first and second toes.
What is the meridian relation function of the Musculocutaneous nerve?
Innervates anterior arm muscles (biceps, brachialis); provides lateral forearm sensation.
Which nerve is most commonly compressed in carpal tunnel syndrome?
Median nerve, leading to numbness and weakness in the hand.
What is the dermatome function of the Median nerve?
Innervates forearm flexors and thenar muscles; sensory function includes lateral palm and fingers.
What is the motor function of the Femoral nerve?
Controls knee extension via quadriceps; provides sensation to anterior thigh and medial leg.
What is the motor function of the Fibular nerve?
Superficial branch controls foot eversion; deep branch controls dorsiflexion and toe extension.
What is the major function of the femoral nerve?
Hip flexion (via iliacus) and knee extension (via quadriceps femoris).
What is the sensory function of the Radial nerve?
Supplies extensor muscles of the arm and forearm; sensory to the posterior arm, forearm, and hand.
What movement is lost with radial nerve palsy?
Wrist and finger extension, leading to ‘wrist drop’.
What is the motor function of the Sciatic nerve?
Innervates posterior thigh muscles and splits into tibial and fibular nerves; sensory to posterior leg and foot.
What is the sensory function of the Fibular nerve?
Superficial branch controls foot eversion; deep branch controls dorsiflexion and toe extension.
What is the sensory function of the Femoral nerve?
Controls knee extension via quadriceps; provides sensation to anterior thigh and medial leg.
