Q

What are the functions of the extrapyramidal tracts?

A

Coordinate automated movements of locomotion & posture (eg to painful stimuli), regulate posture to maintain balance, facilitates mainly a-motor neurones of postural, anti-gravity (extensor) muscles

Q

What are the components of a reflex arc? What happens?

A
  • Sensory receptor responds to stimulus by producing generator or receptor potential.
  • Sensory neurone activated and goes to dorsal part of spine, connecting to interneurone & conducting impulse from receptor to integrating centre
  • motor neurone activated and goes to effector muscles or glands to produce response to stimulus.

Q

What is the moro reflex? When is it developed/when should it disappear? What if it persists?
