A motor neuron's cell body is where?

At end of axon (inside spinal cord)

Along axon (outside spinal cord)

Each neuron contains what

Nucleus, axon, dendrites and terminal branches

Nucleus

Overview of neural circuitry?

Spindle - interneuron - muscle

Spindle - sensory neuron - interneuron - lower motor neuron - muscle

What initiates nervous command?

Cerebral cortex

Motor cortex

Does a reflex require any thought input?

Yes

Ions move...?

Up the concentration gradient

Down the concentration gradient

What is the resting voltage of neurons?

-70v

-90v

What is the resting voltage of skeletal muscle?

-70v

-90v

What is an action potential?

A wave of depolarisation that travels along an axon to stimulate another neuron or muscle fibre

A sea of membrane depolarisation that does not travel along the axon and stimulate another neuron

What is the function of the myelin sheath?

Speed up propogation

Slow down propogation

Electrophysiologic ecording?

1) resting membrane potential 2) depolarisation 3) overshoot 4) repolarisation 5) afterhyperpolarisation 6) return to resting potential

1) resting membrane potential 2) repolarisation 3) overshoot 4) depolarisation 5) afterdehypolarisation 6) return to resting membrane potential

What is the absolute refractory period?

During depolarisation, neuron unable to respond to another stimulus, Na+ channels already open, cant open more

During repolarisation, neuron responds only to very strong stimulus, K+ channels open (Na+ closed, could open again)

What is the relative refractory period?

During depolarisation, neuron unable to respond to another stimulus, Na+ channels already open, cant open more

During repolarisation, neuron responds only to very strong stimulus, K+ channels open (Na+ closed, could open again)
