Transmission speed of Nerve A: 19 m/sec. Transmission speed of Nerve B: 45 m/sec.

Which one is myelinated? explain why.

Expert Solution

Ans. MYELINATED is 45 m/ sec.( Peripheral nerve ) median sensory

19m/sec. ( Intrafusal muscle fibres) -----> THIN MYELIN,, free nerve ending of touch and pressure Nociceptors of neospinothalamic tract cold thermoreceptor .

By jumping from node to node , the impulse can travel much more quickly( 120m/s) .myelinated axons transmit action potential faster than Unmyelinated axon.

Majorities of normal individual fall with in defined ranges : Age, sex, temperature,height,medical conditions etc.

By acting as an electrical insulator ,mylein greatly speeds up action potential conduction . Normal impulse in peripheral nerve of legs travel at 40-45 m/sec.

Myelinated nerve fibre is very fast compared to speed of blood flow, with some myelinated neurons conducting at speed up to 120 m/ sec. ( 432km/h or 275 mph).

A car is safely negotiating an unbanked circular turn at a speed of 19 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one-fourth of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the car?
