Explanation / Answer

Babinski sign is the extensor Plantar response.

Explanation: Plantar reflex elicitation is a very important neurological tool used in bedside clinics.

It is elicited by rubbing the lateral aspect of foot with a designated blunt object(The other side of a knee hammer)

There are 3 responses:

a> Flexor: great toe moves downward(Normal)

b> Indifferent: or absent/No movement of Great toe visible.

c> Extensor: Upward deflection of great toe(Abnormal)

Extensor response is abnormal in adults and found in Upper motor neuron lesion.

However in Infants due to immature Corticospinal tracts, Extensor response is normal.

Q2: nerves that carry both sensory and motor response are knownm as MIXED NERVES

The following cranial nerves are mixed nerves:

Occulomotor

Trigeminal

Facial

Glossopharyngeal

Vagus

Q4. transection of spinal cord leading to permanent paralysis of BOTH lower extremities are known as Paraplegia

*remember Hemiplegia is paralysis of one half of the body(e.g. Left upper and left lower extremities)

Q5. The connective tissue sheath in which every neuron is encapsulated is known as NEURILEMMA
